Unity - Checking if the player is grounded not working

Question

I want the player to jump when the player is grounded.

private void OnTriggerStay(Collider other)
{
    if(other.gameObject.layer == 8)
    {
        isGroun         


        

Answer 1

Use this to check if collision is detected at all, it's good starting point for further debuging:

private void OnTriggerStay(Collider other)
{
   Debug.Log(other);
}
