Question by LukaKotar · May 15, 2012 at 05:54 PM · gameobjecttransformrandom

Pick a Transform[] or GameObject[] from script?

Hi.

I wanted to improve my enemy AI by adding waypoints to it, so it would look a bit more realistic. I've got everything figured out, except for setting a random Transform[] or GameObject[] from a variable for them to go to. Is it possible, or do I need to find another way?

EDIT: Does not need to be random. Just a way to pick them one at a time.

If we assume you have a list or array of items to choose from, you can use Random.Range() to pick an int between 0 and the length of your list, and use the Xth list item.

O$$anonymous$$, thanks! I got the randomization ready, but I don't know how to get it's position. It's just a number.

Here is what I did:

NavComponent.SetDestination(Random.Range(0, wayPoints.Length).position);

NavComponent is a variable that deter$$anonymous$$es which Nav$$anonymous$$eshAgent to use.

For something like that i would use a custom data class like this:

 public class AIPath
 {
     var waypoints : Transform[];
 }

In your actual script you can define a public variable like this:

 var paths : AIPath[];
 private var currentPath : AIPath;

Now you can create multiple seperate pathes. To select a path, just use Random.Range like rutter said.

 currentPath = paths[Random.Range(0,paths.Length)];

Then just use the waypoint array from the currentPath.

 currentPath.waypoints[...]
