We're having trouble with our torch turning on and off all lights

We need to see codes. Right now we can only say that maybe you are using FindObjectsWithTag and all torches have the same tag. But how would I know...?

fafase is right. You need to post the code, or we won't know what you might have done wrong.

It's likely because you're using static variables, so don't do that.

I don't know if this is the right script and I can't get of my friend because he has the script and I wont be able to see him for a while but we're using the toggleLight.

@Eric5h5 is right (as always)

wherever toggleLight is declared, it probably says something like:

static var toggleLight : boolean;

just remove the "static" keyword
