Problem getting objects to collide

Questions & Answers

Seriously, I have tried everything! My dilemma is that I am within a outreach of completing my first game. It seriously can be finished within the next week or two. But there is this certain code (actually two codes but the first one is making me furious) that won’t do want I want it to do. I basically have this code where I want to have a projectile collide with the enemy I have programmed but under any circumstance, the two just will not collide with each other. They both have a collider set upon them, both the same, and the two just won’t collide with each other. I have went through tutorial after tutorial, even to the scripting reference, to figure out this problem but no luck. Here’s the code for the enemy:

#pragma strict

var Miner : GameObject;
var currentHealth : float = 0.0f;
var maximumHealth : float = 20.0f;

function Start () {
	currentHealth = maximumHealth;
	collider.enabled = true;
	collider.material.dynamicFriction = 1;
}

function OnCollisionStay (col : Collision){
	if(col.gameObject.name == "telekinesisball(Clone)")
	{
		Destroy(gameObject);
	}
}


function ApplyDamage (projectiledamage : float) {
	currentHealth -= projectiledamage;
	if(currentHealth <= 0){
	Destroy(Miner);
	}
}

And here’s the one for the projectile moving:

#pragma strict

var object : GameObject;
var speed = 20.0;
var time = 0.0;

function Start () {
	collider.enabled = true;
	collider.material.dynamicFriction = 1;
}

function Update () {
time += Time.deltaTime;
transform.Translate(Vector3.forward * speed * Time.deltaTime, Space.Self);
if(time > 5)
{
Destroy(gameObject);
}
}

function OnCollisionEnter (projectileCollision : Collision)
{
Destroy(object);
}

I probably am missing an important step but it probably flew over my head so some help would be obliged. Please, I am in the final stages of this game and I need this to work. Please help me! thank you.

A common issue with projectiles is that when they are based on colliders, they won’t be detected by the physics engine as rhey are too fast and the colliderof the enemy to thin. To get this working, try to switch detection mode on the projectile rigidbody to contineous or contineous dynamic. Read the Rigidbody docs for further details on which fits your needs exactly. Another option is raycasting, which will definetely solve your problem and es very easy and simple.
