Character Controller wont collide (not a trigger issue)

You posted a generic link to the $$anonymous$$onoBehaviour class which every script derives from; that's not an Answer.

Yes it is because it says there that it is not OnColliderEnter, it is OnCollisionEnter. Thus answering the question of what is wrong with the enclosed code.

Yes it is because it shows the page where the names of all monobehaviour callbacks are listed. If you dont know them you can not search for them. A search for OnColliderEnter is empty.

Yes it is, for more people than the poster, because this is a very useful page that many have not yet found.

Have a nice day, the downvote really made me want to help out more here.

@CarltonSmith, I think what @$$anonymous$$avorka was suggesting (albeit in the most lazy way possible) is that you should check the spelling on your method. Try the following code:

 void OnCollisionEnter(Collision collision) 
 {
     Debug.Log("Collision Detected");
 }

Here is a link to the documentation:

I had a strange issue with mono that was creating lots of red words where there shouldnt be red words. A reinstall of unity and this works fine. Thank you all folks. (All answers upvoted).
