If I bring up anything that has either been mentioned and/or resolved, forgive me.
* When testing any of the Buster Upgrades at Light's Lab, it gives you the weapon instead of replacing the Mega Buster with it. Another bug associated with this is that you are unable to swap weapons via your WEAPPREV bind from the Mega Buster to any Buster Upgrade including IG Metal Blade (if you have no other weapons besides the latter.)
* I know that it is impossible to do (unless proven wrong,) but Gamma can be knocked down by either Mega Ball or Oil Slider. Doing so will produce a pain sound that is abnormally loud.
* KO'd Gamma can still be hit by Super Arm and Ballad Cracker even though it will just re-trigger him getting knocked out.
*Tornado Man's skin has these fluxuating black pixels underneath his arm on his Front and Back second firing sprites (shown in red on the picture below.)
*Whenever a player walks, regardless of skin, there is one frame where the player's sprite will jitter to the first walking sprite and back to standing after the code for walking finishes. This is caused by the PlayerPawn actor coding:Spawn:
PLY1 A 0
PLY1 B 1
PLY1 A 1
Goto Spawn+2
See:
PLY1 BCDE 5
Goto Spawn
The solution to this would be to edit the actor's "See" states thusly:See:
PLY1 BCDE 5
Goto Spawn+2
*I'm almost fairly certain that I pointed this out years ago and I'm slightly miffed that it wasn't resolved.
Looking through DoomBuilder shows that this is caused by the F_SKY1 textures behind those walls. As to why they were pasted there to begin with is anybody's guess.
I haven't gone through everything and might post another thing in the future when I get to it.
