- An actor function really only needs to be an action function if:
1. It can be called with no parameters specified, either because it takes
none or because all its parameters are optional. This lets SetState()
call it directly without creating a wrapper function for it.
2. It wants access to the callingstate or stateowner parameters. Most
functions don't care about them, so passing them is superfluous.
- DECORATE now has atan2(y,x) and VectorAngle(x,y) functions. They are
identical except for the order of their parameters. The returned angle
is in degrees (not radians).
Two issues:
Portal linking requires all skyboxes in the sectors to be present, without them some info is not there when needed.
UpdateWaterLevel was called in AActor::Serialize, which operated on the freshly loaded level where lots of things haven't been set up yet and plane heights may be wrong.
All the PortalBlocks* functions were turned into real function calls which for such a frequent check should be avoided. So now any linked portal sets a flag in the attached sectors so that it isn't necessary to check the skybox pointer each time which makes the functions subject to inlining again.
- When the camera texture for a player view was rendered, its psprites
would overwrite the ones stored for hardware acceleration.
* Use a temporary vissprite in R_DrawPSprite() until it's known that it
will be accelerated.
* Do not write to any of the VisPSprites*[] arrays until it's known that
the sprite will be accelerated.
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 needs to be incremented more locally to the place where it is used, so that it is guaranteed that each viewpoint that needs to be rendered increases it.
As a result the uses in the portal code could be removed.
