CRSA: the corpses

Each level file holds one unnamed CRSA instance, 22048 bytes in every level (20 slots). The game keeps its pointer at GS+0x2f8 and draws the corpses before the characters (0x4e1540). Status: read from the exe and the level files (confirmed). Reader: src/corpse.c.

Offsets are from the instance's data, after its 8-byte header.

Offset	Size	What
0x00	0x0c	Padding (0xdeadde)
0x0c	u32	The level's own corpses (the first slots): 1 in level 1, 17 in level 3, 0 in level 12
0x10	u32	The next slot for a character's corpse (as saved: the count at 0x0c)
0x14	u32	The slots (20)
0x18	0x44c × slots	The slots

A slot (0x44c bytes):

Offset	Size	What
0x000	0x20	The name: the file it was made from (_lvl_3_Intro_TCL_A_corpse.dat), dynamic_corpse for a character's
0x020	0x80	The octree nodes its box lies in (0x440900: a count, then the node indices; −1 counts as always seen)
0x0a0	link	The character class (ONCC); 0 for an empty slot
0x0a4	19 × 0x30	The body parts' matrices (4×3, the translation last), as the character's A+0x2278
0x434	6 floats	The box: min x, y, z, max x, y, z (the character's C+0x1648)

In the game

• ONrCharacter_LevelBegin 0x4d87b0 → 0x4d9d50: the slots after the level's own are cleared and the next slot is set to the first of them.
• A dead AI character (C+4 flag 4, its dying over: on the ground for 120 ticks, 0x78) is deleted once its corpse time (C+0x1644, the class's ONCC+0xc8a) is out, unless its shield or invisibility still shows, C+4 has 0x400, or the character is seen at a detail above the lowest (A+0x221c not 6 nor 0). Its body goes into the next slot first (0x4ef340: the name, the class, the matrices, the box, its octree nodes), unless it fell for 330 ticks (0x14a) or took more than 900 (0x384) to die (C+4 flag 0x80000). The next slot wraps to the first after the level's own.
• trigvolume_corpse (0x4dcbd0) empties the characters' slots whose box's diagonal meets the volume (OBJrTriggerVolume_IntersectsBBox_Approximate 0x4cc630).
• 0x4e1540 draws each slot with a class: a name starting with _ only from the graphics quality 1 (0x508540); the class's first body (TRBS +0), from the quality 3 (0x508550) its second; the textures from the class (0x427da0); only if one of its octree nodes is visible (0x440b50). The port draws them all (it has no octree visibility yet).
