Sometimes a texi component may refer to a material that was initialized by some other costume than the owner costume of the texi component. For example, the candles in gmi have a costume "fx/aura1.cos" that controls the animation of a material originally initialized by a sprite component of "fx/candle.cos".
In Lua, The wear chore of dumbshadow.cos is only started if GetActorPuckVector returns a non-nil value. In the original game GetActorPuckVector seems to always return nil until a call is made to SetActorFollowBoxes.
This fixes the candles not appearing in the set gmi. The original Lua code only starts the candle animation if the candle actor is not playing any chores. Previously the wear chore of dumbshadow.cos was playing, so the animation was never started.
This adds math classes for doing frustum culling in software. These could be used for optimizing performance in many other places as well. For example, if an actor is outside the view frustum, it may not be necessary to do expensive keyframe animation and vertex skinning calculations for that actor.
Lighting is done by calculating vertex colors in software, since the attenuation model used in EMI cannot be simulated with OpenGL fixed function lighting. The original game does the lighting this way as well. Ideally for the modern shader-based renderer a shader would be used for this instead.
The code in pushCostume and the behavior for setColormap(NULL) has been
unchanged since 0.1.0, so there are probably no unintended consiquences
and the functionality should not change without this line.
Fading out chores remain in playing state until they have completely faded out. Also using StopChore on a fading out chore will actually stop the chore, unlike in Grim where the chore will keep fading out.
Some chores need to stay active even after a call to
StopAllChores(). E.g. the hold chores should stay active
even after changing the set (which calls StopAllChores()).
It looks like that the previously unknown boolean paramter
of StopAllChores() controls that behavior. If set to TRUE,
stop only the non-looping chores.
This patch fixes:
- hold chore was lost when switching sets
- blue painting did not show the ultimate insult when opening
the inventory
The hold chore was always lost after e.g. turning left or right.
Although that chore was still in _playingChores, it was not shown.
The patch uses the following order for drawing the chores:
- wear chores
- rest chores
- walk/turn chores
- other chores (in order of the playChore calls)
When attaching an actor to another one, set its local position
so that its final position (position of the parent actor + the
local position) remains the same as the final position before
it was attached.
Use matrix multiplications to fix the rotation for attached actors:
- calculate the final transformation matrix recursively for attached
actors (instead of using getWorldPos and getWorldRot)
- use a different order for building the quaternions out of the Euler
angles
- changed handling of camera position (just apply the rotation of the
camera, the (inverted) position of the camera and the position of the
actor
- no functional changes for GRIM
- no changes for drawing in overworld
Code simplification for GRIM:
- no need to use _currentPos in calculations for GRIM since it is
always (0, 0, 0)
This fixes:
- the rotation of any items Guybrush is holding in his hands
- the handling of the pole when using the raft in the swamps
- getting the bananas with the banana picker
Two animations (guy_puton_cap, guy_holdstickystuff) contain bone names
which which don't match any joints. To avoid that the holding actor is
drawn with a wrong orientation, ingore the unknown bone names when
running the animations.
Skeleton::getJointNamed() will now return null for unknown names.
The original behaviour for Actor::getWorldPos and
Actor::getRotationQuat is kept.
This patch fixes the problem, that Guybrush is "lying down" once he
holds the bottle of glue.
When drawing attached actors the engine uses the parent's sort order
plus one. This offset can move the attached actor behind a background
plane, for instance the chess board in the Lucre docks or Guybrush when
riding the manatee.
