Links through sector portals are not done because nearly all the checks can be performed without doing this so if it works without there's no need to add more processing time.
Will have to see if there's cases left where such a link is needed and if so, whether there's better options to do it.
For line portals such links are necessary to have proper collision detection with actors that are currently transitioning the portal.
- fixed: P_FindFloorCeiling set the floorsector for a new ceilingheight.
Note: P_DrawRailTrail still needs to be changed, at the moment rail trails through portals will not work correctly.
To allow processing the hit through an arbitrary portal without reference to the portal group table, P_AimLineAttack and P_LineAttack need to pass some more info than just the linetarget.
We need the relative positions of shooter and target within the visual reference of the other to calculate proper angles and we need to know if such a portal was crossed at all, because a few things, e.g. seeker missiles won't work with them.
- fixed setup of target acquisition for the Mage Staff.
The pre-acquired seeker target was never passed to the spawned projectiles.
* Arch-Vile resurrection
* Boom point pushers (due to complete lack of z-handling only for line portals.)
* A_RadiusGive
These also require a more thorough collection of portal groups than simple position checks.
- added portal offsetting to all AproxDistance, AngleTo and Vec*To members of AActor.
- optimized displacement retrieval so that the most common case with no offset retrieves a constant null-vector which can be optimized away fully by the compiler.
- early out in P_GetOffsetPosition if there's no portal lines nearby, so that the common case can skip the traverser completely even on maps with line portals.
- Don't use isMissile(). Check directly for the flag at the moment of calling and not the default. Otherwise, things changing themselves will still be ineligible for non-missile checks.
- This is an effort to emphasize that these are just type casts. Now they
look like function-style casts with no action function styling.
They do no magic joojoo at all. The only reason they exist is because
the DECORATE parser can only parse return statements that call a
function, so these satisfy that requirement. i.e. *return int(666);* is
identical to *return 666;* (if the parser could handle the latter).
- Now that state jumps are handled by returning a state, we still need a
way for them to jump to a NULL state. If the parameter processed by this
macro turns out to be NULL, Actor's 'Null' state will be substituted
instead, since that's something that can be jumped to.
- Since DECORATE's return statement can only return the results of
function calls (I do not want to spend the time necessary to make it
return arbitrary expressions), here are three functions to get around
this limitation:
* A_State - Returns the state passed to it. You can simulate A_Jump
functions with this.
* A_Int - Returns the int passed to it.
* A_Bool - Returns the bool passed to it.
- e.g. If you want to return the number 3, you use this:
return A_Int(3);
If you want to jump to a different state, you use this:
return A_State("SomeState");
- The A_Jump family of action functions now return the state to jump
to (NULL if no jump is to be taken) instead of jumping directly.
It is the caller's responsibility to handle the jump. This will
make it possible to use their results in if statements and
do something other than jump.
- DECORATE return statements can now return the result of a function
(but not any random expression--it must be a function call). To
make a jump happen from inside a multi-action block, you must
return the value of an A_Jump function. e.g.:
{ return A_Jump(128, "SomeState"); }
- The VMFunction class now contains its prototype instead of storing
it at a higher level in PFunction. This is so that
FState::CallAction can easily tell if a function returns a state.
- Removed the FxTailable class because with explicit return
statements, it's not useful anymore.
This was to resolve some circular dependencies with the portal code.
The most notable changees:
* FTextureID was moved from textures.h to doomtype.h because it is frequently needed in files that don't want to do anything with actual textures.
* split off the parts from p_maputl into a separate header.
* consolidated all blockmap related data into p_blockmap.h
* split off the polyobject parts into po_man.h
- With multiple A_Jump calls possible in a single action now, it is now
possible for DoJump() to be called with a callingstate that does not
match self->state because the state had been changed by a prior A_Jump
in the same action function.
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.
