Add the JSON format for embedding Actors (Doodad instances) inside of a
Level. I made a test map that manually inserted a couple of actors.
Actors are given to the Canvas responsible for the Level via the
function `InstallActors()`. So it means you'll call LoadLevel and then
InstallActors to hook everything up.
The Canvas creates sub-Canvas widgets from each Actor.
After drawing the main level geometry from the Canvas.Chunker, it calls
the drawActors() function which does the same but for Actors.
Levels keep a global map of all Actors that exist. For any Actors that
are visible within the Viewport, their sub-Canvas widgets are presented
appropriately on top of the parent Canvas. In case their sub-Canvas
overlaps the parent's boundaries, their sub-Canvas is resized and moved
appropriately.
- Allow the MainWindow to be resized at run time, and the UI
recalculates its sizing and position.
- Made the in-game Shell properties editable via environment variables.
The kirsle.env file sets a blue and pink color scheme.
- Begin the ground work for Levels and Doodads to embed files inside
their data via the level.FileSystem type.
- UI: Labels can now contain line break characters. It will
appropriately render multiple lines of render.Text and take into
account the proper BoxSize to contain them all.
- Add environment variable DOODLE_DEBUG_ALL=true that will turn on ALL
debug overlay and visualization options.
- Add debug overlay to "tag" each Canvas widget with some of its
details, like its Name and World Position. Can be enabled with the
environment variable DEBUG_CANVAS_LABEL=true
- Improved the FPS debug overlay to show in labeled columns and multiple
colors, with easy ability to add new data points to it.
Some of the constants in the `balance` package can be set at startup
time via environment variables. With this, you can customize the color
and style of the developer shell, turn on debugging visuals to outline
Canvas widgets, and more.
The parser is at `balance/debug.go` and human readable descriptions
are in the `balance/README.md`
Apart from putting the cached bitmaps in a better place, this about
finishes up the texture caching optimization and IT IS FAST!
When I spam drag a lot of pixels around the FPS may drop to the 40's but
once the caches are warmed up the FPS returns to 60 and stays there,
even if the screen is very busy with pixels.
An undocumented debug feature: set the environment variable
DEBUG_CHUNK_COLOR='#00FFFF' to set a bitmap background color besides
white to be used when caching the chunks. It helps to visualize where on
the screen the bitmaps are being used. May go away in the future.
Changes:
- Found that the old default chunk size of 1000 was slow to generate
bitmap images to cache. The 100px test size was fast and 128 sounds
like a good middle ground number to pick for now.
- Fixed all the problems with scroll behavior and offset by inverting
the sign of the scroll behavior. Scrolling to the Right and Down
actually subtracts X,Y values instead of adds them.
