Why doesn't CompareTag work?

Question

C++ / C#

Hello. I'm trying to make the character take damage from poking into the spikes, he takes damage twice, because there are 2 colliders on him for different purposes, I marked the character's hitbox with the "Player" tag, and the hitbox of the spikes with the "Spike" tag, but I have CompareTag doesn't work, what am I doing wrong?

Here is the code:

private float health = 10f;

    private void OnTriggerEnter(Collider other) {
        if(other.gameObject.CompareTag("Spike") && gameObject.CompareTag("Player")) {
            StartCoroutine(SpikeDMG());
        }
        if(health <= 0)
            Destroy(gameObject);
    }

    IEnumerator SpikeDMG() {
        health -= 5f;
        yield return new WaitForSeconds(0.1f);
    }

Answer 1

you can make a separate empty object on the player, which will contain, in your words, a collider for collisions, and throw a script on this dummy that tracks the touch of the spikes. As a result, only 1 collider will be read, and not as you had 2. You will only have to link 2 scripts (well, the player and the script for responding to the spikes so that when the player gets up on the spike, the damage method is called)
