* 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%.
* 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.
* In WASM build, user levels and doodads are written to localStorage
using their userdir path as keys (".config/levels/test.level")
* LoadFile() and WriteFile() for both Levels and Doodads interact with
the localStorage for WASM build instead of filesystem for desktop.
* userdir.ListLevels() and ListDoodads() for WASM scan the localStorage
keys for file names.
* userdir.ResolvePath() now works for WASM (previously was dummied out),
checks for the file in localStorage.
* Use `go-bindata` to embed built-in doodads and levels directly into
the Doodle binary. `make bindata` produces the bindata source file.
* Add `FromJSON()` method to Levels and Doodads to load objects from
JSON strings in memory (for bindata built-ins or WASM ajax requests)
* Update file loading functions to check the embedded bindata files.
* pkg/config.go#EditFile:
* Supports editing a level from bindata (TODO: remove this support)
* If the "assets/levels/%(simple-name.level)" exists in bindata,
edits that drawing.
* No such support for editing built-in doodads.
* WASM has no filesystem access to edit files except built-in
levels (yet)
* pkg/doodads#ListDoodads:
* Prepends built-in doodads from bindata to the returned list.
* WASM: no filesystem access so gets only the built-ins.
* pkg/doodads#LoadFile:
* Checks built-in bindata store first for doodad files.
* WASM: tries an HTTP request if not found in bindata but can go no
further if not found (no filesystem access)
* pkg/filesystem#FindFile:
* This function finds a level/doodad by checking all the places.
* If the level or doodad exists in bindata built-in, always returns
its system path like "assets/doodads/test.doodad"
* WASM: always returns the built-in candidate path even if not found
in bindata so that ajax GET can be attempted.
* pkg/level#ListSystemLevels:
* New function that lists the system level files, similar to the
equivalent doodads function.
* Prepends the bindata built-in level files.
* WASM: only returns the built-ins (no filesystem support)
* Desktop: also lists and returns the assets/levels/ directory.
* pkg/level#LoadFile:
* Like the doodads.LoadFile, tries from built-in bindata first, then
ajax request (WASM) before accessing the filesystem (desktop)
* Menu Scene: TODO, list the built-in levels in the Load Level menu.
This feature will soon go away when WASM gets its own storage for user
levels (localStorage instead of filesystem)
* Implement the handler code for `return false` when actors are
colliding with each other and wish to act like solid walls.
* The locked doors will `return false` when they're closed and the
colliding actor does not have the matching key.
* Add arbitrary key/value storage to Actors. The colored keys will set
an actor value "key:%TITLE%" on the one who touched the key before
destroying itself. The colored doors check that key when touched to
decide whether to open.
* The trapdoor now only opens if you're touching it from the top (your
overlap box Y value is 0), but if you touch it from below and the door
is closed, it acts like a solid object.
* Move all collision code into the pkg/collision package.
* pkg/doodads/collision.go -> pkg/collision/collide_level.go
* pkg/doodads/collide_actors.go for new Actor collide support
* Add initial collision detection code between actors in Play Mode.
Fixes:
* Move the call to CollidesWithGrid() inside the Canvas instead of
outside in the PlayScene.movePlayer() so it can apply to all Actors
in motion.
* PlayScene.movePlayer() in turn just sets the player's Velocity so the
Canvas.Loop() can move the actor itself.
* When keeping the player inside the level boundaries: previously it was
assuming the player Position was relative to the window, and was
checking the WorldIndexAt and getting wrong results.
* Canvas scrolling (loopFollowActor): check that the actor is getting
close to the screen edge using the Viewport into the world, NOT the
screen-relative coordinates of the Canvas bounding boxes.
