Collision with ground problem (no collision detected)

Questions & Answers
1

I have a cube that can move around (orthographic 2D view), but I also want it to be able to jump when grounded, but I just can't get it to work, and I don't know why, as this should be very simple. Keep in mind that I'm pretty new to Unity.

Here is my script:

void Update()
{
    if (Input.GetButtonDown("Jump") && isJumping == false)
    {
        isJumping = true;
        transform.Translate(Vector3.up * JumpSpeed * Time.deltaTime);
    }

void onCollisionEnter(Collision collision)
{
    if (collision.gameObject.tag == "Ground")
    {
        isJumping = false;
        print("colliding");
    }
}

void onCollisionExit(Collision collision)
{
    isJumping = true;
}

Even though I try to make it print "colliding" while it's in collision, nothing appears in the console. When I test my game, I can only jump once, because the bool isJumping never goes back to false.

Try "OnCollisionExit" and "OnCollisionEnter" instead "onCollisionExit" and "onCollisionEnter".

When you have a doubt, F1 ;)
