I made a quick edit on the action to show exactly what options I would like to add.


I think I should remove Jump eight and run speed, these options will be drive by the vector3 Move.

Obviously I don't know anything about coding so I have no clue of how I will do that.

I think this is exactly what I want to achieve. But can't figure out how to transpose it in playmaker. There lots of things like the Hit distance that is already made is in the Raycast action. But I am always lost when I need to make the collision between my character and the ground.

So to be sure there was not any piece of code making this issue, I started with a fresh new scene.

There is nothing except a the player and the ground, 2 FSM for registering the A input, and the Jump system.



The listener is just a bool test on the press A button.
When A is pressed, the velocity is set to 0 to be sure we start from scratch then set velocity at 5 for 0.25 sec in realtime (I use this because later I need to make a jump that is jumping a bit higher if you hold the button, and it's not something I could do with an addforce2d)

So this is just basic and should work perfectly but:


The Jump should stop just on the top of the edge of this line but goes a bit higher sometime ( usually when  I have many windos open in the editor and checking the fsm to debug)



And a bit shorter sometime (when everything run smoothly and no window is open in the editor)

So I guess the rigidbody or the gravity is not calculated with fixed update.
This is a big issues when you need to do really precise jumps.

Thanks for your help.I didn't really understood what you mean Jean. My issue was the overlapping contact with the "ground checker" and the side walls. The "ground checker" was detecting ground on a side wall because of the tiny overlap collision between the rigidbody2D and the TileMap wall.But what you wrote about probes made me think about a new fix, and this one seems to work well for the moment.
It's simple and didn't think about it before!



I just made an other raycast2D on each side just for detecting side walls.



Then when this ray hit, it changes the length of one of the "ground checker Raycast", so this one will not detect ground any more.
I don't have any slopes in my game so this is working fine.
I let you know if I encounter any unexpected issues!

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?
