OnTriggerEnter requiring both to be rigidbodies ?
I've been reading that for OnTriggerEnter you only need one of the gameObjects to be a rigidbody.
Now that worked just fine for my Tower to detect my Enemy. But when my Tower shoots at the Enemy, the bullet trigger does not work unless I also add a rigidbody to it.
Why is that? The enemy cube is already a rigidbody, why won't OnTriggerEnter work for the bullet unless both the bullet and the enemy cube are rigidbodies?
Is there a better way to do it? Am I doing it the wrong way?
I hope this isn't a bad way to ask a question, I would just like to understand how things work. Thanks in advance for any help
Edit: Posting code as requested, they both already have tags
//enemy
function OnTriggerEnter( other : Collider ) {
if(other.gameObject.tag == "Bullet") {
Destroy(other.gameObject);
}
}
//bullet
function OnTriggerEnter( other : Collider ) {
if(other.gameObject.tag == "Enemy") {
Destroy(gameObject);
}
}
Post the code that is relevant here as there might be a problem with it. And try adding a tag to your enemy and make sure that when the collision happens between the two game objects that the tag is found.
This rule is valid when the trigger is static and other colliders hit it; if the trigger moves and hits other colliders, it must have its own rigidbody - preferably a kinematic rigidbody, since apparently you're moving the bullet via Translate.
Aw I can't upvote you till I have 15 rep. Anyway this makes sense now, thank you so much for explaining it, I knew it had to be something simple. I love you! Is there something wrong with moving the bullet via Translate btw?
Usually the bullet is a regular (non-kinematic) rigidbody, and you just launch it with AddForce or by directly setting its velocity - in this case, the event OnCollisionEnter must be used to detect when the bullet hits something. Take a look at this question to see an example of how to launch a rigidbody bullet.
The rigidbody bullet is easier because you just have to launch it - the physics does the rest. $$anonymous$$oving the bullet yourself via Translate may be better when you want some special behaviour, like a ho$$anonymous$$g bomb.
