/vr/ - Retro Games

so, ive been trying to port over the dragon claw from heretic to doom 2 for a deathmatch wad that uses a_firebullets, and for some reason everything after the firing frame (D frame) is invisible
i have no fucking clue whats causing this and id be very grateful if you guys could fill me in on whats probably a very very simple coding issue on my part
