I have a player, which can turn into a ball (Metroid-clone)
I have a tile map, inside a grid (Layer is ground).
I also have an empty game object named boundaries (That represent the boundaries of the camera) and obviously the layer for this is “No collision”
I went to my project setting and turn off all the interaction with that layer

So, I have my ball, to be a child of my player, and by default is not active, and if I hold the X key, I run a coroutine, that turns my ball on, and I added a raycast, to see if I have something above me, if this is the case I don’t turn of the ball
But I have some problems with this
- if I jump, when I hit the floor, I change into a ball
- I can’t turn back’
If I print what the rayast hit, it was the “Camera boundaries” and of course I is not null
