Hello I'm using Playmaker on my first game and it's awesome, I had a lot of help by reading this forum already!

My game is a platformer 2D and I would like to have the same feeling as Celeste or Meatboy. I started to handle the control of the player by using a Rigidbody2D but I noticed that the jump is inconsistent and the ground check not really good.

Here is one of my issues:



The collider in red is to small and when i hit the border of a platform I can't jump anymore because the ground is not checked.



If i make the ground check collider bigger it might touch the wall when stick to a wall and can jump infinitely.



I tried using raycast2d but I had the same issue. the Ray origin was in the wall due to Physics that allow a small overlapping between the Rigidbody and the collider.

I saw some nice tutorial to create a controller without using Unity physics but they usually don't really explain well the logic behind the code:

My biggest issue is that I don't know how to use Raycast to set up the velocity of my controller. I have all the info with the Playmaker action but I'm lost when i need to use them.

Is it possible to combine as well Rigidbody with this Raycast solution?
OR to say that the raycast only detect a specific normal, so it will hit only the top edge of a boxcollider?
