Spreading objects randomly..

Is there a way to initialize a object randomly across a surface with Javascript? If there is, could you show it to me or make suggestions what I have to look up in order to script something like that?

:roll:

Thanks!

 

Thats the idea!

 

Ah, I'll try to cook up something and get back with some real questions :wink:

 

Could something like this work?

Code (csharp):

1.  
2. //-- Assign to Emty Obj to make it initiate medkits around the scene:
3. //-- Var's:
4. var initMedKit : GameObject;
5.  
6. private var medkitTransform = 0;
7. private var medkitCount = 0;
8. private var totalmedkitCount = 10;
9.  
10. //-- Func's:
11. function Start () {
12. endlessLoop ();
13. }
14. function objMadman () {
15.     if (medkitCount < totalmedkitCount) {
16.    
17.     //-- assigns a var to the initiated medkit's transforms:
18.     medkitTransform = hit.point;
19.  
20. //-- initiate a medkit at the position it should be:
21.     instantiatedExplosion = Instantiate (initMedKit, medkitTransform, transform.rotation);
22.     medkitCount++;
23. //-- Figure out the forward look of the medkit:
24.     var forwardLook = Vector3.Cross (hit.normal, instantiatedExplosion.TransformDirection (Vector3.left));
25.  
26. //-- Build a rotation and assign to the medkit:
27.     instantiatedExplosion.rotation = Quaternion.LookRotation (forwardLook, hit.normal);
28.     }
29. }
30. function endlessLoop () {
31. //-- By the way; will this sort of looping cause strain to the computer? Is there a better way?
32. moveObj ();
33. }
34. function moveObj () {
35. yield WaitForSeconds (5.0);
36. transform.position = Vector3 ( Random.Range (5, 40), 0, Random.Range (5, 40));
37. endlessLoop();
38. }
39. function Update () {
40. //-- cast a ray down from the emty-object
41. var hit : RaycastHit;
42.  
43.     if (Physics.Raycast (transform.localPosition, transform.TransformDirection (Vector3.down), hit)) {
44.     objMadman ();
45.     }
46. }
47.  

But the problem with that is that I've got no way to hit only the desired surfacemesh, the idea here is that the emty object just trasfer itself around the scene like a madman, initiating obj all over the place! But I really need to only initiate obj on 1 surface; the floor!

 

And regarding endless loops, it's much more straightforward to use a while loop than infinite recursion:

Code (csharp):

1.  
2. function LoopDeLoop () {
3.     while(true){
4.        //do something
5.        yield ....;
6.    }
7. }
8.  

... the recursion trick might also overrun your stack space, as mono allocates a stack frame for every function call, but since you never return, the stack never shrinks back. (We might optimise for tail-recursion, but I'm not sure if we do or whether it would kick in in your case.)

 

Ah, thank you for the great input! :wink:

Joachim -> I don't really understand the Renderer.bounds method? Do you have any examples of that( do you use obj.Renderer.bounds or how do I access it? and what does it return?)

 

Thanks! I'll try it..

 

This will be soooo much easer once we have access to the mesh atthe face level! ;-)

 

Then I'll hold my breath and wait for Scheme!
