Trigger mechanism in Unity

Question

Lets say I'm creating a game like Flappy bird, I wanted to trigger when ever the player passes between two pipes so that i can count how many pipes dose the player crossed.

Thanks in Advance.

Answer 1

Create a gameobject with a BoxCollider component, but no renderer.

Scale the BoxCollider such that it encompasses your trigger area.

Then set the collider as a trigger and attach a script to it that contains some desired functionality in the OnTriggerEntered function.

Note: your player gameobject should have a rigid body and collider attached to it, or no collisions will be recorded.

If you wish for this trigger to appear with every obstacle, add it to your obstacle prefab.
