Trouble with light switch
I know there are quite a few topics to do with light switches but I'm really having trouble getting this to work.. I have 3 objects; - sphere (player) - cube (wall) - light
I want to make it so when the player hits the wall, it switches on a light.. I'm trying to get all this done in JavaScript but because I'm still learning it seems to be giving me trouble.. any help would be great! ^_^ Thanks.
Can you describe what you have done and tried? You may want to check up Collier and the trigger functions in the documentation for starters
Well I finally got this thing working!
var linkedLight : Light; //linked to switched off light
function OnControllerColliderHit(triggerLight : ControllerColliderHit)
{
if(triggerLight.gameObject.tag == "wall") //"wall" is the tag on the wall I'm colliding with
{
linkedLight.enabled = true;
}
}
Sorry to bother everyone with the question.. but thanks a lot for the resources, it took me a while, but I finally figured it out :) Now I can add some variables to toggle the light back off again!
Make sure you have physics colliders on all of your GameObjects.
Then, make sure you enable the "Is Trigger" in the Wall GameObject.
You can choose from a number on OnCollision Functions to complete this.
Is this helpful? I can give you more advice if you have more details to share about what you want to accomplish.

I have physics colliders on the sphere and the wall, I didn't think I would need one on the light because it's floating above the player. When I turned on "Is Trigger" for the Wall GameObject it made me run through it.. so I've made a new one just in front which acts as the trigger but doesn't get rendered, I think that way I can still collide with it even though it can't be seen.. The biggest problem I am having now is actually switching the light, I can't seem to find any way of making it work..
Turns out my light switch was fine.. I tried:
var linkedLight : Light; //this is liked to a light which is switched off
function Update ()
{
if (Input.GetKey("q"))
{
linkedLight.enabled = true;
}
}
This worked fine.. when I run the game and press "q" the light switches on.. so I guess my problem lies in the collision... I'm using:
function OnCollisionEnter(triggerLight : Collision)
{
if(triggerLight.gameObject.tag == "wall")
{
linkedLight.enabled = true;
}
}
