Cstat (wall): Difference between revisions

Revision as of 00:43, 31 October 2018

A bitfield for how to draw a wall, as well as a few flags for interaction. Add all together all wanted flag values.

Flag values for wall cstat are:

1 - Make wall blockable

2 - Make bottoms of invisible walls swapped

4 - Align picture on bottom

8 - Flip wall around x-axis

16 - Make wall masking, two-sided

32 - Make wall masking, one-sided

Combine 16 and 32 to disable transparency in the masked texture

64 - Make wall able to be hit by weapons

128 - Make wall transparent

256 - Flip wall around y-axis

512 - Second transparency level (combine with cstat 128)

Unused bits are NOT free for user programming, but are rather reserved for potential future EDuke32 features.
