Can't detect collision.

[Dragonic_TV]

I have a problem with collision detection.
I have my character, he is moving to the z axis automatically.
I have some columns and i want to detect collision with the character…but nothing happens.

Character Movement Script(JS):

function speed_up(){
    for(var i = 0; i  < 200; i++){
        yield WaitForSeconds (10);
        if(speed < 9){
            speed = speed + 0.3 ;
            InvokeRepeating("speed_up", 0, 2);
            can_speed = false;}else{return;}
    }
}

Collision Script:

function OnCollisionEnter(collision: Collision) {
	Debug.Log("LOST");
    if (collision.gameObject.tag == "Block"){
		DefeatText.active = true;
		Time.timeScale = 0;
		Debug.Log("LOST");
    }
}

The Column :

The Character :

TRIED ALSO WITH RIGIDBODY Nothing Happened

Thank you so much for your time!

one of 2 objects needs to have a rigidbody.

both objects need to have colliders.

the moving object needs to move with physics (AddForce).
