Question by skate4life13010 · Nov 13, 2014 at 09:25 PM · cubelistscubesinstantiate-objects

Add gameObjects to List as objects are instantiated

I have a player who moves in a snap grid form. Every movement my player instantiates a cube where it is standing. How can I add these instantiated cubes to a List as they are instantiated? This way I can refer back to this list to see if a cube exisits at a particualr location. In javascript please

 var cube : GameObject; // the cube you want to create
 var cubes : Array = new Array(); //list of cubes
 
 function spawnblock()
 {
 var obj : GameObject = Instantiate(cube, transform.position, transform.rotation);
 
 cubes.Add(obj);
 }

     endCube = gameObject;
     var prefab = gameObject;
     
     var collide : boolean = false;
     
     function OnCollisionEnter(coll: Collision){   //Colliding with object?
         if(coll.gameObject.tag=="floor"){
             collide=true;    
             Debug.Log("collision On");
             }
         else{
             collide=false;
             Debug.Log("collision off");
             }
     }
     function OnCollisionExit(coll: Collision){
         collide=false;            
     }
     
     
     function Update () {
         var myPosition = transform.position;
         if(Input.GetButtonDown("up")){
             transform.position.y = transform.position.y+1;
             Instantiate(prefab, transform.position, Quaternion.identity);
         }
         if(Input.GetButtonDown("down")){
             transform.position.y = transform.position.y-1;        
             Instantiate(prefab, transform.position, Quaternion.identity);
         }
         if(Input.GetButtonDown("left")){
             transform.position.x = transform.position.x-1; 
             Instantiate(prefab, transform.position, Quaternion.identity);
         }
         if(Input.GetButtonDown("right")){
             transform.position.x = transform.position.x+1;        
             Instantiate(prefab, transform.position, Quaternion.identity);
         }
         
         if (Input.GetKeyDown (KeyCode.Space)){
             Instantiate(endCube, transform.position, Quaternion.identity);
     }
 }


I would like to store their vector3 locations so I can go back to look if one has already been instantiated at that place. Unless there is another way to just not instantiate an object when I move on top of a cube. I've tried the simple if (collide == false) but this does not work because the collision functions seem to be called after movement so a cube is placed every other step regardless if there is a cube there
