No collision with the character!

Questions & Answers

I got a problem with my character’s collision: nothing happen when he get hit by the enemy’s bullets (trigger or not). When a bullet hit him, he don’t loss from his health, I checked many times if I add a tag to the bullets and if all the bullets are triggers.

This it part of my character’s code:

function OnTriggerEnter ( hit : Collider)
 {
     //pick ups
	 //works perfect
	 if (hit.gameObject.tag == "bombPick")
	 {
	     bombAmmo += 5;
		 Destroy(hit.gameObject);
	 }
	 if (hit.gameObject.tag == "telePick")
	 {
	     teleAmmo += 4;
		 Destroy(hit.gameObject);
	 }
	 if (hit.gameObject.tag == "rocketPick")
	 {
	     rocketAmmo += 2;
		 Destroy(hit.gameObject);
	 }
	 if (hit.gameObject.tag == "healthCapsule")
	 {
	     if (healthBarDisplay <= 0.6)
		 {
		     healthBarDisplay += 0.4;
		     Destroy(hit.gameObject);
		 }
		 else
		 {
		     healthBarDisplay = 1;
		     Destroy(hit.gameObject);
		 }
	 }
	 
	 //enemy hits
	 //don't works
	 if (hit.gameObject.tag == "STBullet")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.07;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
	 if (hit.gameObject.tag == "LIBullet")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.15;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
	 if (hit.gameObject.tag == "RHBullet")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.1;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
	 if (hit.gameObject.tag == "SPBullet")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.16;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
	 if (hit.gameObject.tag == "SPDrop")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.2;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
	 if (hit.gameObject.tag == "BEBullet")
	 {
	     gotHit = true;
		 healthBarDisplay -= 0.2;
		 yield WaitForSeconds (5.0);
		 gotHit = false;
	 }
 }

If you think it because I loss too low health so I can’t see I lost - you wrong, 100% of the health is 1, so 10% is 0.1.

Another problem with the character collision: I made an ice that should break when something collide with it (if it the character, enemy or something thet fall on it).
When my character collide with it, it don’t break and it only with my character!

This is the ice’s code:

function OnCollisionStay ( collision : Collision) 
 {
     print(collision);
	 Destroy(gameObject, 0.5);
 }

How I make my character have a collision with the bullets and the ice?? My character have CharacterController and Capsule Collider that I added to try solve the problem, and it didn’t helped…

Sorry for poor english.

function OnTriggerStay ( collision :
Collision) {
print(collision);
Destroy(gameObject, 0.5); }

Check out the “Trigger/Collision Action Matrix”

http://unity3d.com/support/documentation/Manual/Physics.html

Are you adding rigidbodies to your colliders? If not then they are “static colliders” and if you check the matrix, static colliders do not interact and send messages with each other. For the collision messages to work correctly it is recommended to have at least one of the colliders to also have a rigidbody component.

I suspect that your pickup objects have rigidbodies attached and your bullets do not, so that could be why one is working and not the other?
