The way this was done was a major headache inducer, requiring reconstruction of the function each time the value was changed and in general made actor damage a major hassle.
There was a DECORATE wrapper to mimic the original behavior but this looked quite broken because it completely ignored the different semantics of both damage calculation types.
It also made it impossible to determine if damage was a function or a value.
This accessor has been reverted to what it should be, only returning the constant, which now is -1 for a damage function. I am sorry if this may break the odd mod out but a quick look over some DECORATE-heavy stuff showed that this was never combined in any of them so that accessing 'damage' in DECORATE code depended on an actual damage function.
To get proper damage, a future commit will add a DECORATE function which calls AActor::GetMissileDamage.
This is necessary to prevent moving sectors from altering the bridge's z-position. The bridge should remain at its current z, even if the sector change would cause floorz or ceilingz to be changed in a way that would make P_ZMovement adjust the bridge.
- don't let P_PushUp move any actors with the same z as the pushing actor. This should solve most monster pile-ups, but the entire logic here needs some serious rethinking. The only reason this doesn't cause more problems is some fudging in several other places.
- ALLOWTHRUFLAGS must be used on the puffs, added for the sake of compatibility with older mods. This applies to the following:
-- Bullets: THRUACTORS, THRUSPECIES
-- Rails: Same as bullets, but includes THRUGHOST.
- restored the original 3D floor code to retrieve the current floor in P_CheckPosition. The portal aware version was a bit too strict and could place the actor on the wrong side when moving at high speeds.
This got accidentally committed. Even if this gets extended to reach through portals it needs to be done differently. FMultiBlockLinesIterator can't guarantee to get every sector that's being touched.
This is for rendering the sprite properly in all areas the actor touches. The original thinglist is not sufficient for this and Boom's touching thinglist has other purposes and collects too much data.
This new list will only get filled in when the actor is actually crossing a portal plane, for the normal sector thinglist will still be used.
This piggybacks on the msecnode_t code which has been extended to be able to handle more than one list by passing the sector's membert pointers as parameters.
This required some changes to the Trace function because it turned out that the original was incapable of collecting the required information:
* actors are now also linked into blockmap blocks on both sides if they occupy the boundary of a sector portal.
* Trace will no longer set up parallel traces in all parts connected with sector portal, but only use one trace and relocate that on the actual boundary.
The only reason this even existed was that ZDoom's original VC projects used __fastcall. The CMake generated project do not, they stick to __cdecl.
Since no performance gain can be seen by using __fastcall the best course of action is to just remove all traces of it from the source and forget that it ever existed.
Sadly the mappers cannot be trusted to use a feature correctly. Despite repeatedly telling that portals on one-sided lines are problematic, everybody seems to do it this way - and then report bugs if it doesn't work. Under such circumstances the only safe option is to block such portals entirely.
See http://forum.zdoom.org/viewtopic.php?f=2&t=51511&p=898522#p898522 for a typical example of the problems this might cause.
This was accidentally deleted during one round of portal refactoring but is essential to prevent multiple teleport activations in one move.
Fixing this also allowed removing the fudging that was added to work around the issue in P_TryMove.
This could happen if the damage calculations resulted in a value between 0 and 1, which for the actual check was multiplied with the damage parameter of P_RadiusAttack which inflated the fractional value to something that looked like actual damage but was later truncated.
While testing this it became clear that with the higher precision of doubles it has to be avoided at all costs to compare an actor's z position with a value retrieved from ZatPoint to check if it is standing on a floor. There can be some minor variations, depending on what was done with this value. Added isAbove, isBelow and isAtZ checking methods to AActor which properly deal with the problem.
Only things left here are accesses to AActor::ceilingz and radius in A_PainShootSkull, plus scaleX and scaleY in the ScriptedMarine sprite setting code.
Most is still using wrapper functions around the fixed point versions.
- Converted P_MovePlayer and all associated variables to floating point because this wasn't working well with a mixture between float and fixed.
Like the angle commit this has just been patched up to compile, the bulk of work is yet to be done.
