AI falls half way in to ground

hey guys, i got a problem and am hoping you guys can fix it. im using unity and im turning a ball in to a AI to chase the player, but when ever i run the game the ball falls half way threw the ground and still chases the player.

I’m sorry, but without further explanation, we can’t do much… Is a SphereCollider attached to your object ? Could you publish some bit of the code you use to chase the player ?

Take a look at this page (Unity - Manual: Introduction to collision). At the very bottom you’ll find a table showing what collider properties and rigidbody combinations that work together.

Note that this is only for collision reference, so far I can’t do much more to help. Hope you find it useful !
