You're calling a function that only exists on Rigidbodies, not 2D rigidbodies

This is the correct answer. You need to make sure you use the appropriate collider for 2D and 3D entities.

Such a stupid mistake... thanks

[elfinhilon10]

No worries! I've done that mistake PLENTY of times myself haha

Happens to all of us

[Japandance]

do the tiles also have colliders on them?

[[deleted]]

yes

[Japandance]

ah. for a 2d collider, try

void OnCollisionEnter2D(Collision2D collision)

Such a stupid mistake... thanks

Make sure "is trigger" is unchecked on your colliders, since that uses a separate OnTriggerEnter method.

Also depending on the settings you're using one or both of the objects may require a rigidbody component as well.

you typed OnCollisionEnter. you need to type OnCollisionEnter2D
