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 "Use Key" (Q or Spacebar) now activates the Warp Door instead of a
collision event doing so.
* Warp Doors are now functional: the player opens a door, disappears,
the door closes; player is teleported to the linked door which opens,
appears the player and closes.
* If the player exits thru a Blue or Orange door which is disabled
(dotted outline), the door still opens and drops the player off but
returns to a Disabled state, acting as a one-way door.
* Clean up several debug log lines from Doodle and doodad scripts.
* The blue and orange ON/OFF state blocks have all been increased in
size to better match the player character (42x42 up from 33x33)
* Added a new mob: the Red Bird. It flies back and forth while
maintaining its altitude, similar to the Red Azulian. Planned AI
behavior is to divebomb the player when it gets close. Dive sprites
are included but not yet hooked up in JavaScript.
* Warp Doors! (WIP). They have a golden "W" on them and come in three
varieties: Brown, Blue and Orange. The blue and orange ones are
sensitive to the State Block and will become dotted outlines when
inactive (and can not be entered in this state). The door opens for
the player character, makes him disappear, then closes again. The plan
is it will then warp you to the location of a linked Warp Door
elsewhere on the level, but for now it will just make the player
re-appear after completing the Close Door animation.
