I'm trying to add a "start-finish" line to the demo car-race game. I've added a cylinder, and resized it to stretch across the road, then buried it, with just a bit exposed. When the car crosses it, the trigger is firing twice for some reason. Any ideas why? Mike I’m a beginner with Unity.

With unity 3 custom layers, trigger become even more awesome. Great thanks. With unity 3 custom layers, trigger become even more awesome.

Before reading this, I wasn't really sure that using colliders was the optimal approach to keeping track of objects that are "near" (versus computing the square of the distance) - it just seemed like the "Unity way" of doing things, and it felt right. :) Regarding other uses for triggers, I'm working on a prototype wherein a "bomb" is instantiated on the scene, and destroys everything that is within a certain radius from it. To do this, I instantiate a sphere collider with the same position as the bomb at the time of the explosion, and a script is attached to this that does a "yield WaitForSeconds(epsilon)", where "epsilon" is a small time value (1/8 of a second or so) representing the effectivity time of the explosion. Then I have an OnTriggerEnter that destroys the entering game objects. Sorry if my description isn't so clear, but I hope you got the idea. :) Thanks for the article and for sharing all this Unity knowledge through all the posts so far, and I'm looking forward to future posts! :) Great post!
