Question

Character falls through the Platform Effector 2D in Unity. How can I fix it?

Here is the demonstration: https://imgur.com/G5YkTxa.

I tried changing the Edit - Project Settings... - Physics 2D - Default Contact Offset from the current 0.01 value to the 0.1 value. The result is the same and here is the demonstration of it: https://imgur.com/3TAOsNY.

Here are my settings for the platform:

Here are my settings for the character's RigidBody 2D:

Here is what character colliders look like when my character runs: https://imgur.com/CTialU3.

I basically run the recorded inside Unity animation of running and move my character with the help of the:

        private void FixedUpdate()
        {
            ... some code which computes the velocity vector depending on the input (the pressed buttons)
            characterRigidBody2D.velocity = velocityVector;
        }

I googled for a while now similar issues, but was not able to find a solution. I want to avoid the character falling down randomly during running.

Answer 1

I really did not want to resort to the one collider per character solution. Even if it is a widespread approach, I feel satisfaction by making the character colliders as accurate as possible. So, I just added an edge collider under the character. A lot of my issues got gone after that. Including the issue described in the question.
