Collision with water won't work

Unity Engine
1

Hey you guys, I’m new to Unity but not at all to scripting and coding.
I have a simple (yet frustrating) problem.
So, I have this ball (my player) that rolling around a surface.
I added water around this surface.
I wanted to trigger a sound when the ball falls into the water but the collision never works.
That’s weird because I have a lot of other collisions with all kind of things that works perfectly fine.
I guess I’m forgetting to configure something with the water but i don’t know what.

I tried to put a tag to the water and check if the collision occurs (from the ball script).
I tried to check with the layer (number 4 - water) also without any luck.
I also tried to detect the collision from the water script.

Is there a component I need to add? Adding a box collider didn’t solve my problem.

This is my first thread so I hope I didn’t left out any important details. If so, tell me and I will add.

Thank you in advance.

*** Update - Works:
It was the silliest thing, I had to use “OnTriggerEnter” instead of “OnCollisionEnter” because the ball fell in to the water and did not “collide” and stopped on the water. ***

Physics is super basic to get things to just collide. Honestly, it just sounds like you need to follow one of the Starter tutorials on physics on Unity Learn.

Also, we don’t need to know that it’s “water”. If you keep your descriptions to physics then it’d be easier to understand i.e. the collider types, the configuration of them i.e. a trigger for instance.

Maybe an image to show it or some code etc.

If the “water” is a trigger then maybe you don’t know you have a different callback than a non-trigger (collision). There are OnTrigger and OnCollision callbacks. Again, starter tutorials go over this.

Yeah I am in the middle of my learning curve. Just couldn’t figure it out…
Thanks anyway.
