In-Depth Information
component Emit is turned off (a script activates it). This script is called
SteamEmitters and it simply turns the emitters on and off based upon the
distance the emitters are from the player:
private var fpcAegis : GameObject;
function Start (){
fpcAegis = GameObject.Find(“FPC_AegisChung”);
}
function Update () {
var dist = Vector3.Distance (fpcAegis.transform
.position, transform.position);
if (dist <=25){
particleEmitter.emit = true;
} else {
particleEmitter.emit = false;
}
}
This is so that when walking through the dark version of the model, the
steam for the entire level isn't visible (the shaders for particles are light
independent). So as the player gets closer, the emitter emits.
The version of steam included in the Steam Unity package also includes
an Audio Source component (Component>Audio>Audio Source) with a
looping steam sound. Importantly, it contains a Box Collider component
(Component>Physics>Box Collider) that is set to be a trigger. Finally, the
Steam GameObject has attached to it the DamagePlayerScript with a Damage
Amount set to 2 (
