* Add "Options" support for Doodads: these allow for individual Actor instances
on your level to customize properties about the doodad. They're like "Tags"
except the player can customize them on a per-actor basis.
* Doodad Editor: you can specify the Options in the Doodad Properties window.
* Level Editor: when the Actor Tool is selected, on mouse-over of an actor,
clicking on the gear icon will open a new "Actor Properties" window which
shows metadata (title, author, ID, position) and an Options tab to configure
the actor's options.
Updates to the scripting API:
* Self.Options() returns a list of option names defined on the Doodad.
* Self.GetOption(name) returns the value for the named option, or nil if
neither the actor nor its doodad have the option defined. The return type
will be correctly a string, boolean or integer type.
Updates to the doodad command-line tool:
* `doodad show` will print the Options on a .doodad file and, when showing a
.level file with --actors, prints any customized Options with the actors.
* `doodad edit-doodad` adds a --option parameter to define options.
Options added to the game's built-in doodads:
* Warp Doors: "locked (exit only)" will make it so the door can not be opened
by the player, giving the "locked" message (as if it had no linked door),
but the player may still exit from the door if sent by another warp door.
* Electric Door & Electric Trapdoor: "opened" can make the door be opened by
default when the level begins instead of closed. A switch or a button that
removes power will close the door as normal.
* Colored Doors & Small Key Door: "unlocked" will make the door unlocked at
level start, not requiring a key to open it.
* Colored Keys & Small Key: "has gravity" will make the key subject to gravity
and set its Mobile flag so that if it falls onto a button, it will activate.
* Gemstones: they had gravity by default; you can now uncheck "has gravity" to
remove their Gravity and IsMobile status.
* Gemstone Totems: "has gemstone" will set the totem to its unlocked status by
default with the gemstone inserted. No power signal will be emitted; it is
cosmetic only.
* Fire Region: "name" can let you set a name for the fire region similarly to
names for fire pixels: "Watch out for ${name}!"
* Invisible Warp Door: "locked (exit only)" added as well.
The gamepad mouse cursor has become THE mouse cursor. It is always visible and your
real cursor is hidden, and this way the game can swap out other cursors for certain
scenarios:
* The Pencil Tool in the editor will use a pencil cursor over the level canvas.
* The Flood Tool has a custom Flood cursor so you don't forget it's selected!
Other improvements:
* The Palette buttons in the editor now render using their swatch's pattern
instead of only using its color.
* If you have an ultra HD monitor and open a Bounded level in the editor which
is too small to fill your screen, the editor canvas limits its size to fit
the level (preferable over showing parts of the level you can't actually play
as it's out of bounds).
* The "brush size" box is only drawn around the cursor when a relevant tool is
selected (Pencil, Line, Rect, Ellipse, Eraser)
* Editor: Auto-save on a background goroutine so you don't randomly freeze
the editor up during.
* Fix actor linking issues when you drag and re-place a linked doodad: the
level was too eagerly calling PruneLinks() whenever a doodad was 'destroyed'
(such as the one just picked up) breaking half of the link connection.
* Chunk unloader: do not unload a chunk that has been modified (Set or Delete
called on), keep them in memory until the next ZIP file save to flush them
out to disk.
* Link Tool: if you clicked an actor and don't want to connect a link, click
the first actor again to de-select it.
Updates to the `doodad` tool:
* `doodad edit-level --resize <int>` can re-chunk a level to use a different
chunk size than the default 128. Large chunk sizes 512+ lead to performance
problems.
* Added to the F3 Debug Overlay is a "Texture:" label that counts the number
of textures currently loaded by the (SDL2) render engine.
* Added Teardown() functions to Level, Doodad and the Chunker they both use
to free up SDL2 textures for all their cached graphics.
* The Canvas.Destroy() function now cleans up all textures that the Canvas
is responsible for: calling the Teardown() of the Level or Doodad, calling
Destroy() on all level actors, and cleaning up Wallpaper textures.
* The Destroy() method of the game's various Scenes will properly Destroy()
their canvases to clean up when transitioning to another scene. The
MainScene, MenuScene, EditorScene and PlayScene.
* Fix the sprites package to actually cache the ui.Image widgets. The game
has very few sprites so no need to free them just yet.
Some tricky places that were leaking textures have been cleaned up:
* Canvas.InstallActors() destroys the canvases of existing actors before it
reinitializes the list and installs the replacements.
* The DraggableActor when the user is dragging an actor around their level
cleans up the blueprint masked drag/drop actor before nulling it out.
Misc changes:
* The player character cheats during Play Mode will immediately swap out the
player character on the current level.
* Properly call the Close() function instead of Hide() to dismiss popup
windows. The Close() function itself calls Hide() but also triggers
WindowClose event handlers. The Doodad Dropper subscribes to its close
event to free textures for all its doodad canvases.
Two new tools added to the Level Editor:
* Pan Tool: left-click to scroll the level around safely.
* Text Tool: write text onto your level.
Features of the Text Tool:
* Can choose from the game's built-in fonts, size and enter the message
you want to write.
* The mouse cursor previews the text when hovered over the level.
* Click to "stamp" the text onto your level. The currently selected
color swatch will be used to color the text in.
* Adds two new fonts: Azulian.ttf and Rive.ttf that can be selected in
the Text Tool.
Some implementation notes:
* Added package native/engine_sdl.go that handles the lower-level
SDL2_TTF logic to rasterize the text into a black&white image.
* WASM not supported yet (if the game even still built for WASM);
native/engine_wasm.go stubs out the TextToImage() call with a "not
supported" error just in case.
Other changes:
* New Toolbar icons: they are 24x24 instead of 32x32 to make more room
for more tools.
* The toolbar now shows two buttons per row for a more densely packed
layout. For very narrow screen widths (< 600px) the default Vertical
Toolbar layout will use one-button-per-row to not eat too much screen
real estate.
* In the Horizontal Toolbars layout there are 2 buttons per column.
* Clean up unused msgpack code for levels and doodads
* Fix the cosmetic bug where actors in your level would display wrongly
when scrolling off the top/left edges of the screen: they used to
anchor at their own 0,0 coordinate and crop their width/height leading
to a 'scrolling' effect that didn't happen on the right/bottom edges.
* The level scroll logic was getting a null pointer crash if you open a
doodad rather than a level file.
* Add a crosshair option to the level editor, configurable in the Game
Settings window.
* Recolor some of the region doodads
* Add command: `doodad edit-level --remove-actor` to remove actors from
your level.
* Tweak the player jump velocity from playtesting levels.
In the level editor, the "Play (P)" button has a new feature: Play
From Here. On mouse down you begin dragging a silhouette of Boy or
whoever the default player character is, as if you were dragging a
doodad onto your level.
Drop the silhouette on your level and enter Play Mode from that
location instead of the Start Flag.
Release your cursor over the Play button or press the "P" key to
spawn at the Start Flag as usual.
Improvements to the Zoom feature:
* Actor position and size within your level scales up and down
appropriately. The canvas size of the actor is scaled and its canvas
is told the Zoom number of the parent so it will render its own
graphic scaled correctly too.
Other features:
* "Experimental" tab added to the Settings window as a UI version of the
--experimental CLI option. The option saves persistently to disk.
* The "Replace Palette" experimental feature now works better. Debating
whether it's a useful feature to even have.
The Doodad Properties window brings many features that used to be
available only in the `doodad` CLI tool into the Doodad Editor.
* In the Doodad Editor there is a new menubar item: "Doodad" which
corresponds to the "Level" menu when you're editing a level.
* The "Doodad" menu has two items:
- "Doodad Properties" (NEW)
- "Layers" (moved here from the Tools menu)
* The Doodad Properties window lets you edit the Title and Author values
of the doodad, as well as modify its Tags and manage its Script.
* Its script can be attached (browse for .js file on disk), its existing
script saved back to disk (dev shell prompt) or deleted altogether
from the doodad.
* You can create, modify, and delete Tags on the doodad.
Other changes:
* In the Level Editor, the "Level->Page Settings" menu is renamed to
"Level->Level Properties" to match with "Doodad->Doodad Properties"
and the pop-up window is retitled accordingly.
* The Exit Flag only exits if the Player touches it - not just any
mobile doodad!
New feature: link a Start Flag to another doodad in your level
and you will play as that doodad instead of Boy. All Creatures
are designed to be playable. Playing as "other" doodads leads
to interesting effects, like not being able to activate buttons,
switches, or warp doors and not having an inventory to pick up
keys. The Anvil is fun: it can destroy other mobile doodads by
jumping on them.
If the actor does not specify that it has gravity, the gameplay
starts in antigravity mode. This will be the vast majority of
non-mobile doodads and the Bird.
Other changes:
* The Blue and Red Azulians now share a doodad script.
* The Azulians AI is still to walk back and forth, pickup keys and
press buttons. The Blue Azulian walks slower than the red one.
* The Blue Azulian is no longer hidden from the doodads list.
* Actor UUID values in levels are now V1 UUIDs (time-ordered).
This will help to reliably resolve conflicts in draw order
of overlapping doodads (newest added to level wins).
* Link Tool: clicking on a pair of already-linked doodads will
now unlink them, so you don't have to delete one to delete
the link.
* Actor Tool: deleting an actor immediately calls PruneLinks()
to clean up any links that the deleted doodad might have.
* pkg/loadscreen implements a global Loading Screen for loading heavy
levels for playing or editing.
* All chunks in a level are pre-rendered to bitmap before gameplay
begins, which reduces stutter as chunks were being lazily rendered on
first appearance before.
* The loading screen can be played with in the developer console:
$ loadscreen.Show()
$ loadscreen.Hide()
Along with ShowWithProgress(), SetProgress(float64) and IsActive()
* Chunker: separate the concerns between Bitmaps an (SDL2) Textures.
* Chunker.Prerender() converts a chunk to a bitmap (a Go image.Image)
and caches it, only re-rendering if marked as dirty.
* Chunker.Texture() will use the pre-cached bitmap if available to
immediately produce the SDL2 texture.
Other miscellaneous changes:
* Added to the Colored Pencil palette: Sandstone
* Added "perlin noise" brush pattern
Note: this commit introduces instability and crashes:
* New `asyncSetup()` functions run on a goroutine, but SDL2 texture
calls must run on the main thread.
* Chunker avoids this by caching bitmaps, not textures.
* Wallpaper though is unstable, sometimes works, sometimes has graphical
glitches, sometimes crashes the game.
* Wallpaper.Load() and the *Texture() functions are where it crashes.
* Added a Settings window for game options, such as enabling the
horizontal toolbars in Edit Mode. The Settings window also has a
Controls tab showing the gameplay buttons and keyboard shortcuts.
* The Settings window is available as a button on the home screen OR
from the Edit->Settings menu in the EditScene.
* Bugfix: using WASD to move the player character now works better and
is considered by the game to be identical to the arrow key inputs. Boy
now updates his animation based on these keys, and they register as
boolean on/off keys instead of affected by key-repeat.
* Refactor the boolProps: they are all part of usercfg now, and if you
run e.g. "boolProp show-all-doodads true" and then cause the user
settings to save to disk, that boolProp will be permanently enabled
until turned off again.
* Free (shareware) versions of the game will not be able to Publish
Levels (attach custom doodads to the level file) and they will not be
able to load a level which relies on embedded doodads.
* The UI for the Publish Level window is still available, but clicking
on the confirm button will just open the Register (License) window.
* When loading a level containing embedded doodads: if some can't load
because they're embedded and you're using the free version of the
game, the error message is customized to reflect that.
* New command-line tool: doodle-admin for signing license keys for
users. Includes functions to initialize a keypair, sign license keys
and validate existing keys.
* The Main Menu screen shows a blue "Register Game" button in the bottom
right corner of the screen, for unregistered users only.
* In Edit Mode, there is a "Help -> Register" menu item that opens the
License Window.
* The License UI Window lets the user select the license.key file to
register the game with. If registered, a copy of the key is placed in
Doodle's profile directory and the licensee name/email is shown in the
License UI window.
* Unregistered games will show the word "(shareware)" next to the title
screen version number and Edit Mode status bar.
* No restrictions are yet placed on free versions of the game.
On small screen sizes like the Pinephone, the toolbars in the Level
Editor are best made horizontal across the top and bottom of the screen
leaving more room for the drawing.
Enable it with a boolProp for now, and then reopen the level editor:
boolProp horizontalToolbars true
When launching `doodle -w mobile` it will automatically enable this
option.
In the Level Editor, the "Level->Attached files" menu opens the
FileSystem Window, which shows a paginated list of attached files and a
"Delete" button to remove them.
- Custom doodads which also exist locally can be deleted from the
level's filesystem at any time.
- If a custom doodad does NOT exist locally, and one of them is still
placed somewhere within the level, you can not delete it.
- You can't delete the custom wallpaper image IF the level is still
using it. Change to a default wallpaper and then you can delete the
custom wallpaper image.
* File->Publish Level in the Level Editor opens the Publish window,
where you can embed custom doodads into your level and export a
portable .level file you can share with others.
* Currently does not actually export a level file yet.
* The dialog lists all unique doodad names in use in your level, and
designates which are built-ins and which are custom (paginated).
* A checkbox would let the user embed built-in doodads into their level,
as well, locking it in to those versions and not using updated
versions from future game releases.
UI Improvements:
* Added styling for a "Primary" UI button, rendered in deep blue.
* Pop-up modals (Alert, Confirm) color their Ok button as Primary.
* The Enter key pressed during an Alert or Confirm modal will invoke its
default button and close the modal, corresponding to its Primary
button.
* The developer console is now opened with the tilde/grave key ` instead
of the Enter key, so that the Enter key is free to click through
modals.
* In the "Open/Edit Drawing" window, a "Browse..." button is added to
the level and doodad sections, spawning a native File Open dialog to
pick a .level or .doodad outside the config root.
* The "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
the door closes; player is teleported to the linked door which opens,
appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
(dotted outline), the door still opens and drops the player off but
returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.
* Added Feature Flag support, run doodle with --experimental to enable
all flags. Eraser Tool is behind a feature flag now.
* + and - on the top row of keyboard keys will zoom the drawing in and
out in Edit Mode. The wallpaper zooms nicely enough, but level
chunkers need work.
* A View menu is added with Zoom in/out, reset zoom, and scroll to
origin options. The whole menu is behind the Zoom feature flag.
* Update README with lots of details for fun debug mode options to play
around with.
* pkg/keybinds holds central functions to check global keybinds, like
DebugOverlay (F3), Undo (Ctrl-Z), GotoPlay/GotoEdit (p/e), etc.
* The Tools menu in the editor mode lists out more options to select
various drawing tools (line, pencil, etc.) - and showing the hotkey
for each tool.
* When editing a doodad in the Editor Mode, the toolbar has a "Lyr."
button that opens the Layers window.
* The Layers window allows switching the active doodad layer that you
are drawing on, as well as create and rename layers.
* With this feature, Doodads may be fully drawn in-game, including
adding alternate named layers for animations and multiple-state
doodads.
* Update the Pager component to have a configurable MaxPageButtons.
Controls that have more pages than this limit will stop having buttons
drawn after the limit. The "Forward" and "Next" buttons can still
navigate into the extra pages.
* Refactored and centralized the various popup windows in Editor Mode
into editor_ui_popups.go; the SetupPopups() and various methods such
as ShowPaletteWindow() and ShowDoodadDropper() make management of
popups simple for the editor_ui!
* The Menu Bar in Editor Mode now has context-specific tools in the
Tools menu: the Doodad Dropper for levels and Layers for doodads.
* Bugfix the Palette Editor window to work equally between Levels and
Doodads, by only having it care about the Palette and not the Level
that owns it.
* Adds global modal support in the pkg/modal/ package. It has easy
Alert() and Confirm() methods to prompt the user before calling a
callback function on affirmative response.
* Modals have global app state: they're processed in the main loop in
pkg/doodle.go similar to the global command shell.
* When a modal is active, a semitransparent black frame covers the
screen (gameplay loop paused, last game frame rendered below) and the
modal window appears on top.
* The developer console retains higher priority than the modal system
and always renders on top.
* Editor Mode: track when the level pixels have been modified, and
confirm the user about unsaved changes when they attempt to close the
level (New, Open, Close, etc.)
* Global: the Escape key no longer immediately shuts down the game, but
will confirm the user's intent via a modal.
* File->Quit in the Editor Mode also invokes the confirm shutdown modal.
* Start the program window maximized with the `-w maximized` CLI option.
* Move the Doodad Palette off the right-side dock of the Editor Scene and
into its own pop-up window: the DoodadDropper.
* Shrink the width of the Color Palette panel and show only the colors in
the buttons. The name of the swatch is available in the mouse-over tooltip.
* Added an "Edit" button to the Color Palette. It opens a Palette Editor
window where you can rename, change colors and attributes of existing colors
OR insert new colors into your palette. (Deleting colors not yet supported).
* level.Chunker gets a Redraw method: invalidates all cached textures of all
chunks forcing the level to redraw itself, possibly with an updated palette.
* Integrate the new ui.MenuBar into the Editor Scene.
* File: New Level/Doodad, Save [as], Open, Close, Exit
* Edit: Undo, Redo, Level options
* Level: Playtest
* Tools: Debug overlay, Command shell
* Help: User Manual, About
* Add an About dialog accessible from the Help menu.
* With the Window Manager update you can open the Level Settings window
while editing a level, to change its wallpaper or page type. But you
could "draw" in the level "through" the opened window. This bug is now
fixed: if the cursor is on top of a managed UI window, the Canvas loop
is not called.
* Take advantage of the new Window Manager feature of the UI toolkit.
* Move the MenuScene's "New Level" and "Play/Edit Level" windows into
stand-alone functions in new pkg/windows/ package. The 'windows'
package is isolated from the rest of Doodle and communicates using
config variables and callback functions to avoid circular dependency.
* MenuScene calls the window constructors from the new package.
* Add an "Options" button to the Menu Bar in the Editor Scene, which
opens the "New Level" window to allow changing the wallpaper or
bounding type of the level currently being edited.
* Move the cheat codes into their own file, cheats.go
* Player character now experiences acceleration and friction when
walking around the map!
* Actor position and movement had to be converted from int's
(render.Point) to float64's to support fine-grained acceleration
steps.
* Added "physics" package and physics.Vector to be a float64 counterpart
for render.Point. Vector is used for uix.Actor.Position() for the sake
of movement math. Vector is flattened back to a render.Point for
collision purposes, since the levels and hitboxes are pixel-bound.
* Refactor the uix.Actor to no longer extend the doodads.Drawing (so it
can have a Position that's a Vector instead of a Point). This broke
some code that expected `.Doodad` to directly reference the
Drawing.Doodad: now you had to refer to it as `a.Drawing.Doodad` which
was ugly. Added convenience method .Doodad() for a shortcut.
* Moved functions like GetBoundingRect() from doodads package to
collision, where it uses its own slimmer Actor interface for just the
relevant methods it needs.
* Update code for recent changes in UI toolkit around event handlers for
buttons.
* Add tooltips to various buttons in the Editor Mode. The left toolbar
shows the names of each tool, the Doodad Palette shows the title of
each doodad and the Color Palette shows the swatch attributes (solid,
fire, water, etc.)
Add new doodads:
* Start Flag: place this in a level to set the spawn point of the player
character. If no flag is found, the player spawns at 0,0 in the top
corner of the map. Only use one Start Flag per level, otherwise the
player will randomly spawn at one of them.
* Crumbly Floor: a solid floor that begins to shake and then fall apart
after a moment when a mobile character steps on it. The floor respawns
after 5 seconds.
* State Blocks: blue and orange blocks that toggle between solid and
pass-thru whenever a State Button is activated.
* State Button: a solid "ON/OFF" block that toggles State Blocks back
and forth when touched. Only activates if touched on the side or bottom;
acts as a solid floor when walked on from the top.
New features for doodad scripts:
* Actor scripts: call SetMobile(true) to mark an actor as a mobile mob
(i.e. player character or enemy). Other doodads can check if the actor
colliding with them IsMobile so they don't activate if placed too close
to other (non-mobile) doodads in a level. The Blue and Red Azulians
are the only mobile characters so far.
* Message.Broadcast allows sending a pub/sub message out to ALL doodads
in the level, instead of only to linked doodads as Message.Publish does.
This is used for the State Blocks to globally communicate on/off status
without needing to link them all together manually.
* The `doodad` CLI tool got a lot of new commands:
* `doodad show` to verbosely print details about Levels and Doodads.
* `edit-level` and `edit-doodad` to update details about Levels and
Doodads, such as their Title, Author, page type and size, etc.
* Doodads gain a `Hidden bool` that hides them from the palette in
Editor Mode. The player character (Blue Azulian) is Hidden.
* Add some boolProps to the balance/ package and made a dynamic system
to easily configure these with the in-game dev console.
* Command: `boolProp list` returns available balance.boolProps
* `boolProp <name>` returns the current value.
* `boolProp <name> <true or false>` sets the value.
* The new boolProps are:
* showAllDoodads: enable Hidden doodads on the palette UI (NOTE:
reload the editor to take effect)
* writeLockOverride: edit files that are write locked anyway
* prettyJSON: pretty-format the JSON files saved by the game.
* The game's tick counter was moved from Doodle.ticks to shmem.Tick
where it is more easily available from every corner of the code.
* Fix a bug in the Level Editor where dragging an already-existing actor
from one part of your map to another, would cause it to lose all its
data (especially its UUID), breaking links to other doodads. Now the
existing Actor catches a ride on the drag object to be reinserted
later.
* Animate the Link Line visualizers between actors. They now animate a
blinking color between magenta and grey-ish.
* Add the other trapdoor directions: Left, Right and Up.
* UI: Show a color square in each Palette Swatch button in Edit Mode.
* Instead of just the label like "solid", "fire", "decoration" it also
shows a square box colored as the swatch color. The label and box
are left-aligned in the button.
* Minor Play Mode physics update:
* The player jump is now limited: they may only continue to move
upwards for 20 ticks, after which they must touch ground before
jumping again.
* Remove the "press Down to move down" button. Only gravity moves you
down.
* Fix a crash in the Editor Mode when you dragged doodads on top of each
other. Source of bug was the loopActorCollision() function, which only
should be useful to Play Mode, and it expected the scripting engine to
be attached to the Canvas. In EditorMode there is no scripting engine.
* Rudimentary scrolling shows a Left and Right button at the top of the
Doodad Palette if your window is deemed not tall enough to contain all
of the doodads.
* A "progress bar" is shown between the buttons indicating the
percentage of your scroll down the doodad list. When you're able to
see the final row of doodads, the progress bar is at 100%.
* Toolbar has icon buttons for the Pencil Tool, Line Tool, Rect Tool,
Actor Tool and Link Tool.
* Remove the tab buttons from the top of the Palette window. The palette
tab is now toggled between Swatches and Doodads by the tool selected
on the tool bar, instead of the tab buttons setting the tool.
* Remove the "Link Doodads" button from the Doodad Palette. The Link
Tool has its own dedicated toolbar button with the others.
* Add support for the LineTool and RectTool while in the EditorMode to
easily draw straight lines and rectangle outlines.
* Key bindings were added to toggle tools in lieu of a proper UI to
select the tool from a toolbar.
* "F" for Pencil (Freehand) Tool (since "P" is for "Playtest")
* "L" for Line Tool
* "R" for Rectangle Tool
* Add a Level Exit doodad, which for now is a little blue flag on a pole
that reads "END"
* JavaScript API: global function EndLevel() will end the level. The
exit doodad calls this when touched by the player.
* Add a "Level Completed" alert box UI to PlayScene with dynamic button
layouts.
* The alert box pops up when a doodad calls EndLevel() and contains
action buttons what to do next.
* "Play Again" restarts the current level again.
* "Edit Level" if you came from the EditorScene; otherwise this button
is not visible.
* "Next Level" is a to-be-implemented button to advance in the single
player story mode. Only shows up when PlayScene.HasNext=true.
* "Exit to Menu" is always visible and closes out to the MainScene.
* Load SDL2 fonts from go-bindata storage so we don't have to ship
external font files on disk.
* Dedupe names of doodads so we don't show double on the front-end
(go-bindata bundled doodads + those on local filesystem)
* Use go-bindata for accessing wallpaper images.
* Better flashed messages walking you through the Link Tool.
* Stylize the title screen (MainScene) by rendering a live example level
as the background wallpaper, with mobile doodads in motion.
* Instead of needing to press the "P" and "E" keys to toggle from edit
mode to play mode (and back again), respectively, the UI now draws a
"Play (P)" or "Edit (E)" button on the bottom right corner of the
level canvas. Clicking it will toggle the mode.
* Fix the EditorUI not showing the correct palette baked into the level
and only showing the default. This was tricky because the palette UI
can only be configured at setup time but not updated later.
* Add a new default palette for the Blueprint theme. Blueprint has a
dark background, so the palette colors should be bright. This palette
is chosen when you start a map with the blueprint wallpaper.
* Add a background Canvas to the MenuScene. In the "New Level" screen,
the background canvas will update to show the wallpaper settings
you've chosen as a preview of the level theme you're about to create.
* To the MenuScene add the "Load Drawing" window UI.
* Displays the user's Levels and Doodads using rows of buttons, 4
buttons per row. Clicking the button loads the EditorScene with that
filename.
* Free Version does not display the Doodads label or button on this
menu screen.
