Issues this fixes:
* all original Doom attack functions unconditionally altered the flash state.
* A_FireOldBFG, A_RailAttack and A_Blast never checked for a valid ReadyWeapon.
* CustomInventory items could deplete an unrelated weapon's ammo.
- SPF_FULLBRIGHT makes the particle full bright.
- SPF_RELATIVE encapsulates the following flags:
- SPF_RELPOS: Position is relative to angle.
- SPF_RELVEL: Velocity is relative to angle.
- SPF_RELACCEL: Acceleration is relative to angle.
- SPF_RELANG: Add caller's angle to angle parameter for relativity.
- NODISTANCE: Disables distance checking.
- CHECKSIGHT: The qualifying actor must be in sight in order to count.
- SET<TARGET/MASTER/TRACER>: Gets the first qualifying actor and sets the calling actor's specified pointer to it.
- SETONPTR: If the function is being aimed at another actor other than the caller, sets that actor's pointers instead. Requires a SET* flag to work.
- FARTHEST: The actor farthest from the checking actor is set as the pointer. Requires a SET* flag to work.
- CLOSEST: The closest qualifying actor is set as the pointer. Requires a SET* flag to work.
- Checks to see if a certain actor class, in numbers, is close to the actor/pointer via distance, based upon count. Can check for ancestry, disable Z searching, perform less than or equal to instead of greater or equal to, exact counts, check a pointer instead of itself and differentiate between live monsters and dead.
- Now includes anglelimit and pitchlimit.
- Anglelimit and pitchlimit only allows the actor to turn this much, similar to A_FaceTarget's limit. FVF_RESETPITCH also respects the pitch limit.
- (offset, anglelimit, pitchlimit, flags, ptr)
- Changes the caller's angle and pitch according to the direction of velocity they're travelling.
- FVF_NOPITCH and FVF_NOANGLE disable changing of pitch/angle respectively and should be counted as mutually exclusive, or the function does nothing.
- FVF_INTERPOLATE - Interpolate's the angle and pitch changes.
- FVF_RESETPITCH will, if there's no z velocity, reset the pitch to 0. Otherwise, the pitch remains unchanged.
The previous version didn't detect some real mistakes in code which used operator& with the wrong flagset (for now 'converted' to the correcly equivalent counterpart, waiting for the proper fix).
- Added 'threshold' and 'defthreshold' to DECORATE expression exposure.
- ChaseThreshold sets the default threshold for how long a monster must chase one target before it can switch targets. Default is 100, must not be negative.
- A_SetChaseThreshold can be used to alter the current or default threshold of an actor <pointer>.
- Changing current threshold has no effect on what the default will be once it hits 0 and something makes it infight with another.
- Performs a jump if an actor or a line is in the way.
- Can be used without a jump state if the desire is only to have a pointer change.
- CBF_NOLINES disables jumping if a line is involved.
- CBF_SET* flags set the target, master or tracer to whoever is blocking, for the actor calling the function.
- CBF_SETONPTR causes the pointer changing flags to apply to the pointed actor instead of itself.
- RadiusOffset is a multiplier of the target actor's radius added onto the offsets x and y.
- Pitch is added to the warping actor's current pitch, provided WARPF_USEPITCH is supplied.
- Fixed WARPF_TOFLOOR not working as intended.
- Actors must be this far away to receive items. Mindist must be less than distance.
- Fixed RGF_OBJECTS not discriminating players and monsters from shootable or vulnerable actors.
- WARPF_ADDHEIGHT adds the pointed actor's height to heightoffset, and adds to the pointed actor's z position.
- WARPF_MULHEIGHT multiplies the pointed actor's height by heightoffset, and adds to the pointed actor's z position. Overridden by ADDHEIGHT.
- Added filter and species parameter.
- Added new flags: RGF_INCLUSIVE, RGF_ITEMS, RGF_KILLED, RGF_EXFILTER, RGF_EXSPECIES, and RGF_EITHER.
- RGF_ITEMS: Items can receive inventory.
- RGF_KILLED: Actors who are truly dead might not be corpses, and vice versa.
- RGF_EXFILTER: Blacklists the specified actor filter. All but the filtered actor can receive the item.
- RGF_EXSPECIES: Blacklists the specified species. All but the filtered species can receive the item.
- RGF_EITHER: The actor can receive the item if it satisfies either the filter or the species. Only useful when both are used.
- RGF_INCLUSIVE: An actor marked as more than one pointer to the calling actor can ignore the exclusion pointers, but only if at least one is missing. I.e. an actor who is a target and tracer of the calling actor can still receive the item, if the calling actor doesn't pass RGF_NOTARGET and NOTRACER at the same time. RGF_INCLUSIVE only works with the pointer filtering flags. By default, if not specified, the actor will not be loopholed the item if they are under any one of the three filters.
- Fixed discrepancies and dependencies upon several flags and actor conditions which caused the function to fail.
- Overrides the NOTELEPORT flag so actors with velocity don't need to disable it in order to perform A_Teleport, which could be screwed up by a teleporting line or sudden ACS interference.
- Ensure that the result is set to false if it fails prematurely. Wasn't sure if this was needed, but with the upcoming if/else statements, better safe than sorry.
- (int ptr = AAPTR_TARGET, state high, state low, float offsethigh = 0, float offsetlow = 0, bool includeHeight = true)
- Jumps if the pointer of the calling actor is higher or lower than itself, adding offsethigh or offsetlow depending on the circumstance.
- includeHeight works twofold.
- Includes the height of the calling actor if the pointer is higher to truly determine if they are completely above them or not.
- Includes the height of the pointer if the pointer is lower.
- Disable it to only check z differences without adding height.
