A_FireShotgun
From DoomWiki.org
A_FireShotgun is a code pointer used in the attack animation for the shotgun. It implements the main shotgun firing logic.
A_FireShotgun does the following:
- Sets the player into state
S_PLAY_ATK2so that other players in the game see the player firing a weapon. - Activates the weapon's "flash state" that shows the gun-barrel flash.
- Plays the sound effect DSSHOTGN.
- Fires seven pellets in the direction that the player is facing (performing autoaim to determine vertical angle).
Uses[edit]
The A_FireShotgun code pointer appears in the following states in Doom's state table:
| Frame number | Doom internal name | Use |
|---|---|---|
| 22 | S_SGUN2 | attack animation for the shotgun |
Example[edit]
The following is an example of how to set the A_FireShotgun code pointer in a DeHackEd file:
Pointer 21 (Frame 34) Codep Frame = 22
Or using BEX syntax:
[CODEPTR] Frame 1234 = FireShotgun
Code structure[edit]
A_FireShotgun uses the same P_GunShot function as A_FirePistol and so its code structure is largely identical.
