- replaced some uses of FRACUNIT with OPAQUE when it was about translucency.
- simplified some overly complicated translucency multiplications in the SBARINFO code.
- 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.
Patched up everything so that it compiles without errors again. This only addresses code related to some compile error. A large portion of the angle code still uses angle_t and converts back and forth.
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.
* removed all code for dealing with z-displacing portals in the iterator loops. This would cause too many problems so I decided to scrap any provisions for allowing interactive portals with z-displacement. They will remain restricted to pure teleporter portals.
* changed spechit to carry a position along with the special line. If something is activated through an interactive portal this is needed to calculate movement.
* pass the abovementioned position to CheckForPushSpecial.
* collect touched portal lines in a second array analogous to spechit.
* use FMultiBlockThingsIterator in P_TestMobjZ.
A big problem with this function was that some flags required setting up some variables before calling it and others did not. It will now set everything up itself so all initializations to AActor::floorz and ceilingz that were made before these calls (which were all identical to begin with) could be removed and the internal initialization logic streamlined.
- removed Plane/Floor/CeilingAtPoint functions because they are overkill for the problem they were meant to solve. Calling ZatPoint with adjusted coordinates created with AActor::PosRelative is just as easy in the few places where this is needed.
- made P_HitWater and P_CheckSplash portal aware.
