New doodad interactions:
* Sticky Buttons will emit a "sticky:down" event to linked doodads, with
a boolean value showing the Sticky Button's state.
* Normal Buttons will listen for "sticky:down" -- when a linked Sticky
Button is pressed, the normal Button presses in as well, and stays
pressed while the sticky:down signal is true.
* When the Sticky Button is released (e.g. because it received power
from another doodad), any linked buttons which were sticky:down
release as well.
* Switch doodads emit a new "switch:toggle" event JUST BEFORE sending
the "power" event. Sensitive Doodads can listen for switches in
particular this way.
* The Electric Door listens for switch:toggle; if a Switch is activated,
the Electric Door always flips its current state (open to close, or
vice versa) and ignores the immediately following power event. This
allows doors to toggle on/off regardless of sync with a Switch.
Other changes:
* When the player character dies by fire, instead of the message saying
"Watch out for fire!" it will use the name of the fire swatch that
hurt the player. This way levels could make it say "Watch out for
spikes!" or "lava" or whatever they want. The "Fire" attribute now
just means "instantly kills the player."
* Level Editor: You can now edit the Title and Author name of your level
in the Page Settings window.
* Bugfix: only the player character ends the game by dying in fire.
Other mobile doodads just turn dark but don't end the game.
* Increase the size of Trapdoor doodad sprites by 150% as they were a
bit small for the player character.
* Rename the game from "Project: Doodle" to "Sketchy Maze"
* 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.
