Why doesn't my collision detection script work when using OnTriggerEnter, however when using OnCollisionEnter it doesn't work at all... Would really like to know.. Thank you in advance

When your Collider is marked as isTrigger (in the inspector) you can use OnTriggerEnter else you can use OnCollisionEnter

I did that, I disabled isTrigger, however the same problem still happens
