504bb08a64 - we do not really need the old rintersect function.
Its only difference is using potentially overflowing 32 bit math for demo compatibility. Aside from that it has no real-life advantage.

a23d2ae656 - fixed OOB access in pushmove.
The backwards search loop starts at one element behind the data it is supposed to check. If this is the last wall in the map it accesses undefined memory.

This tripped the range check in TArray for wall[].

d8ccfa1a5f - cleaned up nextsectorneighborz, added a safe variant and use this in all places where the sector pointer is not validated. 2021-12-26 23:10:05 +01:00

1ee1c0c920 Revert "- fixed: updatesectorneighborz may not return -1."
This reverts commit c074b0995648a4057c516e5646f5fe7a11719317.

* The commit notes talk about `updatesectorneighborz()`, but the change is applied to `nextsectorneighborz()`. Further to this, `nextsectorneighborz()` is only called from some ptr wrappers in `build.h` and they both test against `-1` return values.

```
inline sectortype* nextsectorneighborzptr(int16_t sectnum, int32_t refz, int16_t topbottom, int16_t direction)
{
	auto sect = nextsectorneighborz(sectnum, refz, topbottom, direction);
	return sect == -1? nullptr : &sector[sect];
}

inline sectortype* nextsectorneighborzptr(sectortype* sectp, int32_t refz, int16_t topbottom, int16_t direction)
{
	auto sect = nextsectorneighborz(sector.IndexOf(sectp), refz, topbottom, direction);
	return sect == -1? nullptr : &sector[sect];
}
```

* Also fixes broken Duke elevators and possibly a whole raft of issues.

8e2d324e85 - fixed: updatesectorneighborz may not return -1.
This value gets never validated by any caller and isn't really what is wanted in this situation.

838bed7800 - final cleanup of sectnum related stuff.
Made sure that remaining uses of sector indices are safe to be kept and deleted a few redundant functions.

d3b1e34d78 - moved sprite[], spriteext[] and spritesmooth[] into DCoreActor.
Also removed the last remaining sprite pointer in saveable data.

f855b1020f - actor lists refactored.
No more shorts, no more static arrays.
This was one of the biggest blockers for unlimiting the engine.

87ac9bee44 - refactored the owner index in tspritetype.
This is now a separate type from spritetype which contains an actor pointer instead so that sprite display can be handled without requiring a static sprite array.

19236b2526 - removed compatibility handling for the oldest level from hitscan.
This stuff isn't even slope aware so the only legitimate reason for keeping it would be demo playback.

d30bf8c8bb - fixed Blood's mirror render hack for Polymost.
This adds 4 walls and 1 sector without counting them, so we must adjust allocations and array access to handle OOB access and temporarily increase the counter for the mirror render pass.

The new renderer does not need this stuff.

999ec3c95a use validSectorIndex checks where appropriate.
Let’s hope that this sloppiness doesn’t have negative effects with broken maps.
