Uses[edit]
The A_Saw code pointer appears in the following states in Doom's state table:
| Frame number | Doom internal name | Use |
|---|---|---|
| 71 | S_SAW1 | attack animation for the chainsaw |
| 72 | S_SAW2 | attack animation for the chainsaw |
Example[edit]
The following is an example of how to set the A_Saw code pointer in a DeHackEd file:
Pointer 21 (Frame 34) Codep Frame = 72
Or using BEX syntax:
[CODEPTR] Frame 1234 = Saw
Code structure[edit]
A_Saw uses largely the same underlying functions as A_FirePistol and other tracer attack functions. P_AimLineAttack is used to aim in the direction of a monster in front of the player and P_LineAttack performs the attack. Unlike with ranged weapons, the functions are called with a very limited range. These two functions use the standard path traversal functions (P_PathTraverse) to identify targets in the direction the player is facing.
