Collision Updating UI Slider only once.
I'm making a flat 2D fighting game, and I'm trying to update my player2Health slider when player 1 collides with player 2 (of course I don't know if I am going this the right way, it's my first game). Preface: Also spent about an hour or so researching, but maybe I didn't search for the right thing.
For now I have the step working of where the slider updates OnCollisionEnter2D but it's only firing once.
void OnCollisionEnter2D (Collision2D col) {
if (col.gameObject.tag == "Player2")
{
GameHud.player2HealthUI.value = currentHealth - 10f;
Debug.Log ("Colliding with player 2");
}
}
Am I using this the wrong way? I thought to use OnTriggerEnter2D but then making my player gameobjects triggers make them fall through other colliders.
You should be doing this in order to ceep track of the currentHealth
void OnCollisionEnter2D (Collision2D col) {
if (col.gameObject.tag == "Player2")
{
currentHealth-= 10;
GameHud.player2HealthUI.value = currentHealth;
Debug.Log ("Colliding with player 2");
}
}
Wow. Thanks so much and all it took was one line. I will keep this in $$anonymous$$d when I have other objects (like special moves) or so. So for future reference, when I am updating a gameobject value, or meter, etc.. I should update the variable before changing the value, correct? (Not try and do both at the same time which is probably what I was doing) Just making sure I understand this right.
