My 2D object keeps on falling through the terrain (cube)

I wouldn’t usually ask this because it seems so simple, but I’ve tried so many tutorials and questions on this site. So I really need somebody’s help.

Basically I’m a Unity noob, and i want to make a simple 2D platformer to play and review on. My problem is, is that the 2D player falls through the terrain, even though both of them have a box collider on them.

Sorry for my bad english, if you can answer this then thank you :smiley:

If your terrain is a cube, ensure that the box collider is not, “BoxCollider2D.” Also ensure that they are both on the same Z axis, as it’s possible that your cube may not be touching your sprite at all.
