* Fix collision detection to allow actors to walk up slopes smoothly, without
losing any horizontal velocity.
* Fix scrolling a level canvas so that chunks near the right or bottom edge
of the viewpoint were getting culled prematurely.
* Centralize JavaScript exception catching logic to attach Go and JS stack
traces where possible to be more useful for debugging.
* Performance: flush all SDL2 textures from memory between scene transitions
in the app. Also add a `flush-textures` dev console command to flush the
textures at any time - they all should regenerate if still needed based on
underlying go.Images which can be garbage collected.
* Added a Cheats Menu UI accessible from the Settings window's "Experimental"
tab and from there you can enable the Cheats Menu from the "Help" screen of
the gameplay mode.
* Commonly used cheats all have corresponding buttons to click on, especially
helpful for touchscreen devices like the Pinephone where keyboard input
doesn't always work reliably.
* The buttons in the Cheats Menu just automate entry of the cheat commands.
* `boolProp` command has a new `flip` option to toggle their value (e.g.
`boolProp show-hidden-doodads flip`)
Previously: the Chunker tracks with chunks were gotten during the
current game tick and the N-1 and N-2 ticks, and chunks not accessed in
two ticks were freed immediately.
Now: they go into a "garbage collection" pool with a minimum number of
game ticks to free. So if they're needed again, they're saved from the
gc pool. F3 overlay data shows the count of the gc pool.
* Bird is not solid when colliding with other birds.
* If the dev shell is used to run JavaScript during Play Mode, consider
it cheating (so player can't `$ d.Scene.ResetTimer()` for example)
* On Survival Mode levels, DieByFire immediately opens the End Level
(silver score) modal rather than respawn from checkpoint, so levels
don't need checkpoint contraptions to end the level.
* During level loading screens, wait and call doodads' main() function
until the very end.
* When playing as the Bird, the dive attack is able to destroy other
mobile doodads such as Azulians and Thieves.
* The Box has been made invulnerable so it can't be destroyed by Anvils
or player-controlled Birds.
* Bugfixes with pop-up modals:
* The quit game confirm modal doesn't appear if another modal is
already active on screen.
* The Escape key can dismiss Alert and Confirm modals.
* Add "Level" menu items to Play Mode to restart the level or retry from
the last checkpoint (in case of softlocks, etc.)
* The title screen now loads the default maps from a LevelPack. The game
no longer ships with the Tutorial levels in the "levels" folder as
default; they are in the LevelPack so the "Edit Drawing" screen begins
as a blank slate for only user levels.
* Add the Zoo level to the Tutorial levelpack
* Bugfixes around changing the player character to work around clipping
issues if the character has changed height drastically.
* Add methods `Invulnerable() bool` and `SetInvulnerable(bool)` to the
Actor API accessible in JavaScript (e.g. `Self.SetInvulnerable(true)`)
* The Anvil is invulnerable - when played as, it can crush other mobs by
jumping on them but is not defeated by those mobs at the same time.
* Anvils don't destroy invulnerable mobs, such as other Anvils.
* Bugfix: the Electric Door is considered to be opened from the first
frame of animation when the door begins opening, and remains opened
until the final frame of animation when it is closing.
* New cheat code: `megaton weight` to play as the Anvil by default.
* 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.
* If the player runs the PlayAsBird cheat they shouldn't be able to win
a high score on a level, so at level startup it detects whether the
DefaultPlayerCharacterDoodad has changed from default on a level that
doesn't use the Start Flag to set a specific doodad - and immediately
marks the session as cheated
* New doodad: Invisible Warp Door
* All warp doors require the player to be grounded (if affected by
gravity) to open them. No jumping or falling thru and opening
a warp door mid-air!
* Title Screen now randomly selects from a couple of levels.
* Title Screen: if it fails to load a level it sets up a basic
blank level with a wallpaper instead.
* New developer shell command: titlescreen <level>
Opens the MainScene with a custom user level as the background.
* Add Auto-save to the Editor to save your drawing every 5 minutes
* Add a MenuBar to the Play Scene for easier navigation to other
features of the game.
* Doodad JS API: time.Since() now available.
* Added the Death Barrier to Play Mode to catch players from falling off
the map and then falling indefinitely, especially on Unbounded maps.
* The Death Barrier is set 1,000 pixels below the lowest point on your
map. If the player falls here they get a death message: "Watch out for
falling off the map!"
* Added cheat codes to change the default Player Character doodad, as a
way to force play as a different character (for levels which don't
specify a custom character):
* Play as Bird: fly like a bird
* Play as Blue Azulian: the cell
* Play as Thief: play as thief
* Reset to default (Boy): pinocchio
* The pattern textures for level palettes have been brightened and work
better with bright colors.
* The three default palettes for new levels now have patterns applied to
each of their colors.
* Bugfix around resetting keybind states for Zoom In/Out, Scroll to
Origin and Reset Zoom Level bindings.
