* Increase the default window size from 800x600 to 1024x768.
* Move the drawing canvas in EditorMode to inside the EditorUI where it can
be better managed with the other widgets it shares the screen with.
* Slightly fix Frame packing bug (with East orientation) that was causing
right-aligned statusbar items to be partially cropped off-screen. Moved a
couple statusbar labels in EditorMode to the right.
* Add `Parent()` and `Adopt()` methods to widgets for when they're managed
by containers like the Frame.
* Add utility functions to UI toolkit for computing a widget's Absolute
Position and Absolute Rect, by crawling all parent widgets and summing
them up.
* Add `lib/debugging` package with useful stack tracing utilities.
* Add `make guitest` to launch the program into the GUI Test.
The command line flag is: `doodle -guitest`
* Console: add a `close` command which returns to the MainScene.
* Initialize the font cache directory (~/.cache/doodle/fonts) but don't
extract the fonts there yet.
The `level.Canvas` is a widget that holds onto its Palette and Grid and
has interactions to allow scrolling and editing the grid using the
swatches available on the palette.
Thus all of the logic in the Editor Mode for drawing directly onto the
root SDL surface are now handled inside a level.Canvas instance.
The `level.Canvas` widget has the following properties:
* Like any widget it has an X,Y position and a width/height.
* It has a Scroll position to control which slice of its drawing will be
visible inside its bounding box.
* It supports levels having negative coordinates for their pixels. It
doesn't care. The default Scroll position is (0,0) at the top left
corner of the widget but you can scroll into the negatives and see the
negative pixels.
* Keyboard keys will scroll the viewport inside the canvas.
* The canvas draws only the pixels that are visible inside its bounding
box.
This feature will eventually pave the way toward:
* Doodads being dropped on top of your map, each Doodad being its own
Canvas widget.
* Using drawings as button icons for the user interface, as the Canvas
is a normal widget.
* Added a "menu toolbar" to the top of the Edit Mode with useful buttons
that work: New Level, New Doodad (same thing), Save, Save as, Open.
* Added ability for the dev console to prompt the user for a question,
which opens the console automatically. "Save", "Save as" and "Load"
ask for their filenames this way.
* Started groundwork for theming the app. The palette window is a light
brown with an orange title bar, the Menu Toolbar has a black
background, etc.
* Added support for multiple fonts instead of just monospace. DejaVu
Sans (normal and bold) are used now for most labels and window titles,
respectively. The dev console uses DejaVu Sans Mono as before.
* Update ui.Label to accept PadX and PadY separately instead of only
having the Padding option which did both.
* Improvements to Frame packing algorithm.
* Set the SDL draw mode to BLEND so we can use alpha colors properly,
so now the dev console is semi-translucent.
* Add ui.Window to easily create reusable windows with titles.
* Add a palette window (panel) to the right edge of the Edit Mode.
* Has Radio Buttons listing the colors available in the palette.
* Add palette support to Edit Mode so when you draw pixels, they take
on the color and attributes of the currently selected Swatch in your
palette.
* Revise the on-disk format to better serialize the Palette object to
JSON.
* Break Play Mode: collision detection fails because the Grid key
elements are now full Pixel objects (which retain their Palette and
Swatch properties).
* The Grid will need to be re-worked to separate X,Y coordinates from
the Pixel metadata to just test "is something there, and what is
it?"
These properties will be globally useful to all sorts of Widgets and
have been moved from the Button up into the Common widget, and its
interface extended to configure these:
* Padding int32
* Background color
* Foreground color
* Border size, color and style (default solid; raised; sunken)
* Outline size and color
The button adjusts its border style from "raised" to "sunken" for
MouseDown events and its Background color for MouseOver events. Other
widgets such as Labels and Frames will be able to have borders, paddings
and outlines too, but they will be off by default.
The Buttons can now be managed by a ui.Supervisor and be notified when
the mouse enters or leaves their bounding box and handle click events.
Current event handlers supported:
* MouseOver
* MouseOut
* MouseDown
* MouseUp
* Click
Each of those events are only fired when the state of the event has
changed, i.e. the first time the mouse enters the widget MouseOver is
called and then when the mouse leaves later, MouseOut is called.
A completed click event (mouse was released while pressed and hovering
the button) triggers both MouseOut and Click, so the button can pop
itself out and also run the click handler.
With Labels and Buttons so far.
* Labels are pretty much complete, they wrap a render.Text and have a
Compute() method that returns their Width and Height when rendered
onto an SDL Surface.
* Buttons wrap a Label widget and Compute() its size and takes that into
consideration when rendering itself. Buttons render themselves from
scratch in a "Windows 95" themed way, with configurable colors, border
widths and outline.
* Add a debug view that draws the player bounding boxes.
* Improve the collision detection to add support for:
* Doodads being "Grounded" so gravity need not apply.
* Walking up hills, albeit a bit "bouncily"
* Harder to clip out of bounds
Implements the dev console in-game with various commands to start out
with.
Press the Enter key to show or hide the console. Commands supported:
new
Start a new map in Edit Mode.
save [filename.json]
Save the current map to disk. Filename is required unless you
have saved recently.
edit filename.json
Open a map from disk in Edit Mode.
play filename.json
Play a map from disk in Play Mode.
