* Tweak max gravity speed to match player max velocity.
* Boy's script watches for his velocity to flip suddenly and stops
animations, limiting the moonwalking a bit.
* JS API: Self.GetVelocity() added.
This commit adds the Thief character with starter graphics
(no animations).
The Thief walks back and forth and will steal items from other
doodads, including the player. For singleton items that have no
quantity, like the Colored Keys, the Thief will only steal one
if he does not already have it. Quantitied items like the
Small Key are always stolen.
Flexibility in the playable character is introduced: Boy,
Azulian, Bird, and Thief all respond to playable controls.
There is not currently a method to enable these apart from
modifying balance.PlayerCharacterDoodad at compile time.
New and Changed Doodads
* Thief: new doodad that walks back and forth and will steal
items from other characters inventory.
* Bird: has no inventory and cannot pick up items, unless player
controlled. Its hitbox has also been fixed so it collides with
floors correctly - not something normally seen in the Bird.
* Boy: opts in to have inventory.
* Keys (all): only gives themselves to actors having inventories.
JavaScript API - New functions available
* Self.IsPlayer() - returns if the current actor IS the player.
* Self.SetInventory(bool) - doodads must opt-in to having an
inventory. Keys should only give themselves to doodads having
an inventory.
* Self.HasInventory() bool
* Self.AddItem(filename, qty)
* Self.RemoveItem(filename, qty)
* Self.HasItem(filename)
* Self.Inventory() - returns map[string]int
* Self.ClearInventory()
* Self.OnLeave(func(e)) now receives a CollideEvent as parameter
instead of the useless actor ID. Notably, e.Actor is the
leaving actor and e.Settled is always true.
Other Changes
* Play Mode: if playing as a character which doesn't obey gravity,
such as the bird, antigravity controls are enabled by default.
If you `import antigravity` you can turn gravity back on.
* Doodad collision scripts are no longer run in parallel
goroutines. It made the Thief's job difficult trying to steal
items in many threads simultaneously!
* The F4 key to draw collision boxes works reliably again: it draws the
player's hitbox in world-space using the canvas.DrawStrokes()
function, rather than in screen-space so it follows the player
reliably.
* The F4 key also draws hitboxes for ALL other actors in the level:
buttons, enemies, doors, etc.
* The level geometry collision function is updated to respect a doodad's
declared Hitbox from their script, which may result in a smaller box
than their raw Canvas size. The result is tighter collision between
doodads, and Boy's sprite is rather narrow for its square Canvas so
collision on rightward geometry is tighter for the player character.
* Collision checks between actors also respect the actor's declared
hitboxes now, allowing for Boy to get even closer to a locked door
before being blocked.
* The colored locked doors and the Electric Door are increased in size
to better match Boy's sprite size.
* Colored doors now have a "locked" and "unlocked" state when closed;
when locked, a gold padlock hangs on the door with a keyhole shaped to
match the corresponding Colored Key.
* Added initial walking sprites for the player character, "Boy."
* Player doodad filename and title screen level are now configurable in
the balance/numbers.go package.
