A_Lower
From DoomWiki.org
A_Lower is a code pointer used in the weapon lower animation for all weapons.
A_Lower moves the Y position of the weapon sprite towards the bottom of the screen by a small amount each time it is invoked. If the bottom of the screen is reached, the next weapon is selected and the raise state is invoked to bring it up. A_Lower is usually used in a state that is an infinite loop that repeatedly jumps back to itself; the loop terminates when the weapon has finished lowering.
Uses[edit]
The A_Lower code pointer appears in the following states in Doom's state table:
| Frame number | Doom internal name | Use |
|---|---|---|
| 3 | S_PUNCHDOWN | weapon lower animation for the fist |
| 11 | S_PISTOLDOWN | weapon lower animation for the pistol |
| 19 | S_SGUNDOWN | weapon lower animation for the shotgun |
| 33 | S_DSGUNDOWN | weapon lower animation for the super shotgun |

Example[edit]
The following is an example of how to set the A_Lower code pointer in a DeHackEd file:

Or using BEX syntax:
