Help with simple Collision Detection, no rigid bodies.

Ok, i saw a few post about that but none of them are solving this problem.

I have a simple scene.

One Box

one Plane

Both objects created within unity and both objects with colliders (The plane a mesh collider, the box a box collider)

Now i'm using an script to move the box up and down, now i want to print a message everytime the box crosses the plane, something like

print ("i Crossed");

One script i'm using is this, but don't work, i was looking for the solution within the help, but i cannot find anything.

Code (csharp):

1.  
2.  
3. function Update () {
4. }
5. function OnCollisionEnter(collision : Collision) {
6.     print ("kaka");
7. }
8.  
9.  

Help please! i need this to understand the collisions.

Thanks!

 

Use OnTriggerEnter instead... OnCollisionEnter requires a non-kinematic rigidbody:

I tried too

Code (csharp):

1.  
2. function OnTriggerEnter (other : Collider) {
3.     print ("kaka");
4. }
5.  

But after that i noticed that:

 

You need to attach a rigidbody and make it kinematic.

 

Thanks, it workied...it's not too elegant, but is working
