llSetDamage

Summary

Function: llSetDamage( float damage );

0.0	Forced Delay
10.0	Energy

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

• float

damage

–

range: 0.0 (no damage) ~ 100.0 (instant kill)

Specification

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.

Caveats

• damage is not a Prim Property, and thus damage is only active so long as the script applying the damage is in the object, and is running.
• If damage is 100.0 or greater, the object will instantly kill even a fully healthy avatar.
• If damage is zero or less, no damage will be inflicted and the object will not die and the collision or land_collision events will be queued.
• If a damage enabled object hits a physics enabled object that an avatar is sitting on, the avatar receives the damage just the same as they would if they had been hit directly.

Examples

//Simple autokiller bullet:
// This will instantly "kill" on collision if contact is made with avatar on damage enabled land.

default
{
    on_rez(integer param) // Becomes active when rezzed.
    {
        llSetDamage(100.0); // Set the damage to maximum.
        llSensor("", "", AGENT, 96.0, PI); // Sweep a 96 meter sphere searching for agents.
    }
    sensor(integer num) // If an agent is detected...
    {
        llSetStatus(STATUS_PHYSICS, TRUE); // Enable physics to allow physical movement.
        llSetTimerEvent(10.0); // Set a 10 second timer.
        llMoveToTarget(llDetectedPos(0), 0.5); // Move to the detected position.
    }
    no_sensor() // If no agents are detected...
    {
        llDie(); // Auto destruct.
    }
    timer() // If we missed our target...
    {
        llDie(); // Auto destruct.
    }
}
