aab13addb7 -renamed spritetype’s owner field to ‚intowner‘ 
Mainly for easier searching.
Also remove the duplicate ‚detail‘ field.

4e2a9f6e59 - use float wall positions in portal code. 2022-02-15 22:18:26 +01:00

651c25a7be - do the 'inside' check with integers. 
Using floats and multiplications is not robust enough. This is a bit slower, but doesn't run the risk of underflows and other nasties.
Q: How many bits of fractional precision should we use? 16 seems fine

a781517780 - renamed PlanesAtPointf to PlanesAtPoint 
The old PlanesAtPoint is not needed anymore.

f44736a5b6 -use an access function for reading wall positions so that we have a non-modifiable value wherever this is possible. 2022-02-15 22:18:23 +01:00

89ef81da55 - renamed walltype::pos as preparation for refactoring. 
no functional changes here

e892de21ec - preparations for unlimited tsprites. 
Right now it is a no-op because Polymost cannot deal with this properly.

91d51d518b - this hack is needed because dragging vertices around can randomly create wall intersection. 
In clear English: Geometry in Build maps is always broken by design. :(

415dc5246d - fixed sprting of non-translucent sprites. 2022-01-08 21:18:18 +01:00

1849fe541e - fixed alignment of sloped sprites. 
The offset fields are not valid for them so thwy may not be used for offsetting.

717dd123e5 - fixed slope sprite flag getting cleared by some leftover code. 
Also merged copyfrom into the one single function that called it.

4bc32e2777 - use actors in the sloped sprite utilities. 2021-12-30 16:11:14 +01:00

44d2cc1951 - eliminated usectorptr_t. 2021-12-30 11:45:58 +01:00

3fee8f3c4e - replaced dragpoint (both the generic and the Blood variant) with a newly written vertexscan function. 
This is a template allowing to run any task on a set of walls with equivalent start point.
Code was redesigned from scratch to be more clear than the existing variants.

The idea here is to reuse the base algorithm for other things that need to operate on the equivalent set of a given wall's start point.

f602cf3806 - deal with s() in shared code. 
clip.cpp was left alone, except for the actual call.

beddf1e1ca - add slope sprite support to the new renderer. 
Some fudging was needed to avoid positioning problems as the renderer is more sensitive to this than Polymost.
 2021-12-30 09:56:55 +01:00
Christoph Oelckers
65bc6e6aef - removed the now redundant wall() and sector() interator helper functions. 
With both wall and sector now being TArrays they are not needed anymore.

82fb03e399 - another batch of search&replace, with smaller results. 2021-12-30 09:56:48 +01:00
Christoph Oelckers
1edccf1423 - added slope setter methods to sectortype. 
To make sure that setting the slope flags is always done properly. (Why are the flags even needed?)
As a nice side effect, this, plus use of other inlines made the align*slope functions implode into virtually nothing.
 2021-12-30 09:53:56 +01:00

24a6d45f97 - minor slope math optimization. 
May save one division and merges the '<< 5' into the main calculation.
 2021-12-30 09:53:56 +01:00
Christoph Oelckers
5f18109371 - consolidated all getslope code into a single function. 
This also caches a wall's length to avoid taking the square root every single time for a slope calculation.
 2021-12-30 09:53:55 +01:00
Christoph Oelckers
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.

eaff9e359f - 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.
 2021-12-26 23:09:53 +01:00
Christoph Oelckers
12f6b05cbe - use access functions, all done by search & replace. 2021-12-26 23:09:44 +01:00

9380819e4e - initialize actorArray for all games. 
- the foundation for an actor aware backend.

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

5ba005276f Revert "- redid the 'inside' function." 
This reverts commit c034c2a299.

While the function works, it is subtly different for points exactly on a line - enough to cause problems with Shadow Warrior's waypoint implementation.

c034c2a299 - redid the 'inside' function. 
This is based on external information and does not use any of the original Build code.
Despite being a lot clearer than Build's bit masking voodoo and using 64 bit math to avoid overflows it is roughly 10% faster. :)

Code was moved to gamefuncs.cpp because this no longer falls under the Build license.
