- Includes four functions, A_SetSprite(Angle/Rotation) and GetSprite(Angle/Rotation).
- SpriteRotation offsets the angle of the sprite, allowing for actors to move backwards or sideways for example.
- SpriteAngle requires +SPRITEANGLE and sets the actor's sprite to the absolute rotation found at that angle. Overrides SpriteRotation once the flag is on.
- Clears a set of overlays in ranges [start,stop]. If unspecified, wipes all non-hardcoded layers. Safety determines whether to affect core layers or not (i.e. weapon). Returns the number of layers cleared.
Added no override boolean to A_Overlay and a boolean return type.
- If true, and a layer already has an active layer, the function returns false. Otherwise, sets the layer and returns true.
SPF_NOTIMEFREEZE processes particles with this flag regardless of time freeze. The endsize parameter changes the scale of the particle to that size throughout its lifetime linearly.
- Source is the actor to blame for the cause of damage (monster infighting for example). For missiles, modders should consider setting to AAPTR_TARGET.
- Inflictor is the actor doing the damage itself. Note that by changing this, it will take into account the flags on the pointed actor.
- float GetZAt(x, y, angle, flags, pick_pointer);
- Gets the floor z at x distance ahead and y distance to the side in relative form from the calling actor pointer. Flags are as follows (GZF_ prefix):
- CEILING: Returns the ceiling z instead of floor.
- ABSOLUTEPOS: x and y are absolute positions.
- ABSOLUTEANG: angle parameter does not add the pointer's angle to the angle parameter.
- FLATSPRITE: An actor becomes flat as if they were a decal on the floor.
- PITCHFLATSPRITE: A flat sprite tilts up and down based on pitch.
- WALLSPRITE: Similar to a Y billboarded sprite. The degree of the flattening is determined by the FlatAngle property.
- ROLLSPRITE: The sprite of the actor is affected by the Roll property.
- This reverts commit 06216d733e.
- I don't know what I was thinking. Since stateowner is always available
to the wrapper function, and this code is only generated for the wrapper
function, it's a nonissue. The state is already located before calling
any function that uses it.
- This reverts commit 39df62b20e.
- Anything that needs to lookup a state also needs stateowner. See
FxMultiNameState::Emit(). I will need to be more selective when
de-actionifying functions.
- An actor function really only needs to be an action function if:
1. It can be called with no parameters specified, either because it takes
none or because all its parameters are optional. This lets SetState()
call it directly without creating a wrapper function for it.
2. It wants access to the callingstate or stateowner parameters. Most
functions don't care about them, so passing them is superfluous.
- Includes 2 flags, affixed by CBF_: AbsolutePos, and AbsoluteAngle.
- AbsolutePos: Absolute position of where to check.
- AbsoluteAngle: Angle parameter is used as is, not added onto the actor's current angle.
