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.
- started converting g_hexen.
Most importantly this removes CHolyWeave as it is just a specialized version of A_Weave with far more convoluted use of parameters.
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.
I can't believe I missed this for more than 10 years, considering that A_CustomMissile explicitly implements this case:
It makes a crucial difference whether P_SpawnMissileZ is used or the actual z-position is temporarily changed.
Reverted this function to the position changing method of the original.
- 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.
- 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.
To summarize, anything that just works with map geometry doesn't need to bother, as does the renderer. (i.e. nearly all r_* files, p_floor.cpp, p_ceiling.cpp et.al)
But all calls that are somehow related to actor positions need to be made aware of potential portal transitions:
* added FloorAtPoint, CeilingAtPoint and PlaneAtPoint methods to sector_t, which can be used to calculate a plane's height with relation to a given actor, even if that actor is on the other side of a portal.
* added HighestCeilingAt and LowestFloorAt methods which traverse all ceiling/floor portals until they find an impassable plane.
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
Converting a floating point value that is out of range for a signed integer will result in 0x80000000 with SSE math, which is used exclusively for this purpose on modern Visual C++ compilers, so this cannot be used anywhere.
On ARM there's problems with float to unsigned int conversions.
xs_Float does not depend on these
