Get list of nearby targets (JS)
Hello,
I've been attempting to make a function that allocates all nearby gameobjects into a variable and then sorting them by range, but haven't had much success. Would a list or array be more appropriate and how would I be able to implement it successfully?
you have 2 ways:
put a trigger with a colider in the center of your GO and you can check what hit the colider if you are using JS
make an GO array
function OnCollisionEnter(collision : Collision) {
array.Add(collision .gameobject);
}
if you are using c#

and for the sorting use this example

get all the game objets in the scene and filter it first by the minimum distance you want distance and then by the distance itself.
filter any Go outside your radius
var allgameObjs : GameObject[] = FindObjectsOfType(GameObject) as GameObject[];
var gameObjs : GameObject[];
for(i:int=0;i radius) {
gameObjs .Add(allgameObjs[i]);
}
}
then sort them like here
