A_Explode [(int explosiondamage [, int explosionradius [, int flags [, bool alert[, int fulldamageradius[, int nails[, int naildamage]]]]]])]


Performs an explosive (radius) attack. The amount of damage and the attack's radius are specified with explosiondamage and explosionradius, respectively. If the actor is a missile, you can set hurtshooter to 0 so that its originator will not be harmed by the attack. If the hurtshooter parameter is omitted, the shot will assume normal behavior and damage the shooter.


  • explosiondamage: How much damage are inflicted at the center of the explosion. (Default: 128)
  • explosionradius: The area covered by the damage (damage inflicted drop linearly with distance). Note that a radius larger than 32767 extends beyond ZDoom's map space limitations, and will overflow with undesired results (such as becoming too small and damaging nothing). (Default: 128)
  • flags: The following flags can be combined by using the | character between the constant names: (New from 2.7.1)
    • XF_HURTSOURCE — Hurts the source: if set, the source can be damaged by the explosion. Note that the source is not necessarily the calling actor. This flag is set by default. (New from 2.7.1)
    • XF_NOTMISSILE — Not a missile: if set, the calling actor is considered to be the source. By default, the calling actor is assumed to be a projectile, and the source is therefore considered to be the calling actor's target. (New from 2.7.1)
  • alert: Whether the explosion rings the alarm? (Default: false)
  • fulldamageradius: The area within which full damage is inflicted. (Default: 0)
  • nails: The number of horizontal hitscan attacks performed in a ring. (Default: 0) A value of 30 emulates the A_NailBomb codepointer from SMMU, while still allowing to modify all other parameters from A_Explode.
  • naildamage: The amount of damage inflicted by nails, if any. (Default: 10)

Do not use the old actor property method of passing the parameters. Only use the parameters of A_Explode directly.
