Problems with BoxColliders2D

Can someone help me?

I have a problem with BoxColliders2D.They are normal, but when I press play and the player falls, he leaves a small space between it and the platform also has the normal BoxCollider2D.

(Here are the Box colliders, all normal.)


(When I press play and the player falls, Box colliders do not touch, it is a small space separating the two. I tried with a cube and made no difference, it looks like it is with any object.)

Please helpp!

(If it says something wrong, sorry, I do not speak English.(Thanks Google Translate))

Do we have any Portuguese speaking people here? :3

You must follow Unity 2D tutorials

Or download the platformer game in the asset store and dig how it is done and re use same scripts

Look at the reply from the Unity mod on this, he explains the cause
