A_WeaponAlert

A_WeaponAlert is a weapon function that is part of the MBF21 specification. It alerts monsters within sound-travel distance of the player's presence. It can be used to override the effect of the SILENT flag, which stops a weapon from alerting monsters.

Example

The following is an example of how to set the A_WeaponAlert code pointer in a DeHackEd file using BEX syntax:

Frame 13
Next frame = 1234

Frame 1234
Next frame = 14

[CODEPTR]
FRAME 1234 = WeaponAlert

Or using DECOHack syntax:

state 13
{
PISG A 4
goto 1234
} 

state 1234
{
 TNT1 A 0 A_WeaponAlert
 goto 14
}

The example above uses A_WeaponAlert on an invisible, zero-duration state to alert nearby monsters the moment the pistol is fired (state 14). This assumes that the pistol itself has been given the SILENT flag, since the use of A_WeaponAlert would otherwise be redundant.
