Help with 2d player character collision

Hello everyone,

what is the best way to detect collision with corner of next ground (red circle)?

 

If it has a box collider on the platform/ground the player will collide with the edge of an object as well as the top & bottom if they come into contact with it.

 

If character don't jump so he will crash into next ground. How do I detect collision?

 

If he's not touching it there's no collision, if he's touching it then there's a collision. You can't detect a collision with the ground in the air if he isn't actually touching it.

 

Yes,but he is touching ground and he will crash into next ground.

 

I don't understand what the issue is. If you have a box collider around the next ground he will hit the edge of it & not pass through it.

 

How do I find different between front and bottom collider ? Because character can walk on top on ground. But he cannot touch ground from front.

 

I still don't understand why you don't want him to touch the ground from the side.

Anyway, You can place a cube or something in front of the upper ground & turn the mesh renderer off so you can't see it or you can do a raycast down to detect what is under the players feet.

 

I'd suggest starting here, if you check through them you will find a tutorial section for 2d
