- 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.
- Places the weapon offset by the defined x and y. Both are floats. This stacks with weapon bobbing.
- WOF_KEEPX: Don't change the X offset.
- WOF_KEEPY: Don't change the Y offset.
- WOF_ADD: Add onto instead of replacing the coordinates.
- 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.
Since decals may have thinkers attached this will crash when such a savegame gets loaded, because the thinker lists get reset in P_SerializeThinkers, deleting any thinker that already was processed.
I also added an error message that immediately aborts the save process if such an out-of-sequence thinker is attempted to be written out.
This obviously breaks savegame compatibility again...
The scripting branch changed camera semantics to default to an actor's center - which for monsters and decorations makes sense - but not for simple mapspots that get used as camera. For those the CameraHeight must be explicitly set to 0.
ZDoom defaulted to Boom's (buggy) angle adjustment.
Changed it so that
* Mode 0 is like Hexen, performing no adjustment at all. This still should match all known maps using this special.
* Mode 1 remains unchanged.
* Mode 2 replicates Boom's broken angle adjustment and is used in the xlat file.
* Mode 3 implements the correct angle adjustment that Boom originally intended.
(Note: Should some map require something different it should be handled with compatibility.txt instead of reverting this back to the broken way it was before.)
