Get list of nearby targets (JS)

you have 2 ways:

1. 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

1. 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
