Hi great codder firstly sory for my bad english. So ı wrote this cod for my player enable to jump only his child emty object touch the ground layer mask

public void isGrounded() { Collider[] collider = Physics.OverlapSphere(GroundChecker.position, GroundCheckerRadius, GroundLayer); if(collider != null) { Debug.Log(name); CanJump = true; } else { Debug.Log(2); CanJump = false; } }

But the main problem is whenever ı try consol gave me player name even player arent on Ground Layer mask
