Good afternoon,
I am doing a test for platform game but when falling from the platform and colliding by the sides my character is clinging to the platform and stops falling.
How can I resolve this?
How can I make a collision with a certain object, without being with everyone?
Follow the link for my project:

Thank you very much !
Not sure what you mean by this? Can you provide screenshots?
This is known as collision filtering. The physics library we use is ammo.js which a compiled version of Bullet. Collision filtering is not exposed in the editor but you can set the group and masks (both are bitmasks) in code like so:
this.entity.rigidbody.group |= 1 << 6;
this.entity.rigidbody.mask |= 1 << 6;
The Bullet documentation on how this works can be found here: http://www.bulletphysics.org/mediawiki-1.5.8/index.php/Collision_Filtering
If you are making a 2D physics based game, then you may also want to consider using p2.js which is lighter weight than ammo.js. Will wrote the integration scripts on this project: PlayCanvas 3D HTML5 Game Engine
