Instantiate random prefab along z axis

Hi! I'm trying to instantiate 5 random prefabs after eachother along the z axis.
I have 5 pieces of a map that should randomly generate itself.
I want to start the instantiate fiva seconds after the scene has loaded and every five seconds after that.
Could someone please help me with this, I'm totally stuck!

 

Do somethhing like

if(Time.time - lastSampledTime >= 5000) { // do it }

So that you can execute your code after passing 5 seconds.

 

That worked great! But how do I do the instantiate part? 'Cause that's where I'm stuck

 

Try to put your maps under Resources directory (if there is no create one) Then you can use Resources.Load to load your maps. Please check Resources.Load function for details.I hope it helps

 

Welcome to the forum, Jappejab!

If you want to make something happen at a regular time interval, you can put it in a function and use InvokeRepeating:-

Code (csharp):

1. function RandomPrefabFunc() {
2.   // Instantiation code goes here...
3. }
4.  
5. function Start() {
6. // Call RandomPrefabFunc every 5 seconds.
7.    InvokeRepeating("RandomPrefabFunc", 0, 5.0);
8. }

Note that time is measured in seconds rather than milliseconds in Unity, so you should not multiply the interval by 1000.

 

You would need the Instantiate part as well, I am guessing...

Code (csharp):

1.  
2. Instantiate (prefab, transform.TransformPoint(Vector3(0, 0, Random.Range(-100.0, 100.0))), Quaternion.identity);
3.  

So this would be a random point between -100 and 100 along the Z axis of the current transform.

 

Thanks alot! This is the script I now have but it doesn't work. What am I doing wrong?

Code (csharp):

1.  
2. var mapPiece : Rigidbody[];
3.  
4.  
5. function RandomPrefabFunc() {
6. Instantiate (Rigidbody, transform.TransformPoint(Vector3(0, 0, Random.Range(-100.0, 100.0))), Quaternion.identity);
7. }
8.  
9. function Start() {
10. // Call RandomPrefabFunc every 5 seconds.
11.    InvokeRepeating("RandomPrefabFunc", 0, 5.0);
12. }

 

mapPiece is declared as a Rigidbody array, so you must access the array locations.
Try:

Instantiate (mapPiece[Random.Range(0, mapPiece.length)], transform.TransformPoint(Vector3(0, 0, Random.Range(-100.0, 100.0))), Quaternion.identity);

I could be wrong on syntax, but that ought to do it.

 

Okey, that helped a bit. But the prefab still won't instantiate, my current code is:

Code (csharp):

1. var mapPiece : Rigidbody[];
2.  
3.  
4. function RandomPrefabFunc() {
5. Instantiate (mapPiece[Random.Range(0, mapPiece.length)], transform.TransformPoint(Vector3(0, 0, Random.Range(-100.0, 100.0))), Quaternion.identity);
6. }
7.  
8. function Start() {
9. // Call RandomPrefabFunc every 5 seconds.
10.    InvokeRepeating("RandomPrefabFunc", 0, 5.0);
11. }

 

Need a bit more information bud. Lol. Is there an error? Are you sure it isn't instantiating and you just can't see it?

Note, I just copy/paste your code into my own unity file and it worked as expected. Make sure in the inspector you are filling out your mapPiece array with rigidbodies. Also, make sure you can see them! Lol.

 

i restarted Unity and now it works xD

 

Okey, so the instantiate function works perfect, now I want it to create the prefabs at a set position. That position is the same as the objekt the script I put on, plus 10 in the z axis. How do I do this?

 

You do realize that forum users aren't going to just write the script for you right? You have to learn and figure some things out on your own. When there's a hang up it's great to ask a question, but it isn't realistic to keep asking until the project is done. Look at the docs, it's how I learned. Read some tutorials, unity is wide-spread by now and they're everywhere. Then get back to your project.

But to answer your question, currently the script instantiates them in a range along the z that is +/- 100 from the center of the GameObject the script is attached to. If you want it to spawn always at position+10,

Code (csharp):

1. Instantiate (mapPiece[Random.Range(0, mapPiece.length)], transform.TransformPoint(Vector3(0, 0, 10)), Quaternion.identity);

Or if you mean the +/- range occurs with it's center at position+10, then use

Code (csharp):

1. Instantiate (mapPiece[Random.Range(0, mapPiece.length)], transform.TransformPoint(Vector3(0, 0, 10+Random.Range(-100.0, 100.0))), Quaternion.identity);
