Function: llSetDamage( float damage );

Sets the amount of damage that will be done when this object hits an avatar.

• float damage range: -100.0 (full heal) ~ 100.0 (instant kill)


For an avatar to take damage when the object collides with an avatar...

  • The object must not be phantom or llVolumeDetect(TRUE)
  • The avatar must be on the land where "Safe (no damage)" is disabled.
    • The object however does not need to be on or even partially over damage enabled land.

When these preconditions are met, the avatar receives the damage, and the object will die without calling the collision events.


  • damage is a Prim Property, and may be applied even if there is no running script.
  • If damage is 100.0 or greater, the object will instantly kill even a fully healthy avatar.
  • If damage is less than zero, the avatar will he healed for the indicated amount.
  • If a damage enabled object hits a physics enabled object that one or more avatars are sitting on, damage will be distributed to all seated avatars.
