Question about Instantiate rotation

I'm new to Unity, javascript and so..

So, I'm having an issue with the rotation of an instance of an prefab.

My character shoots projectiles, and when it hits something, it's supposed to spawn another prefab at the same position, and the Y rotation parallel to the plane it hits. But with the following code, the prefab spawns at the opposite rotation, perpendicular to the plane...

Any clues how I can get this to work properly ?
Thanks

 

what's your issue? Is your splash not oriented properly? The look rotation will align the forward vector of the transform to the supplied direction in this case.

 

Yeah...it goes the opposite orientation....

 

well you can try:

Code (csharp):

1. function OnCollisionEnter (collision : Collision)
2. {
3. var contact : ContactPoint = collision.contacts[0];
4. var rot : Quaternion = Quaternion.LookRotation(-contact.normal);
5. var pos : Vector3 = contact.point;
6.  
7. Instantiate(splash, pos, rot);
8.  
9. // Destroy the projectile
10. Destroy (this.gameObject);
11.  
12. }

 

unfortunately it remains the same =(

 

what does your splash look like? If the splash is just a plane then its forward vector (blue arrow) should be sticking out of the plane.

 

Well...I've just solved it, I think....

The splash looks like a plane, for testing purposes..
And i've never thought the orientation i used to build the prefab would make a diference....

You made me realise that....I've just switched the X and Z dimensions and it's all right now
and i'm laughing a lot at it....a simple sollution to something i've spent almost a hole day to solve =D

Thanks a lot man !
Specially for answering so fast
