Set only one child object visible

Questions & Answers

Hi everyone,

This is my first question on these boards.

I have a scene for a RTS game that is filled with units (just basic capsules). When I click a unit I wan’t to set a plane visible that is attached as a child to the unit. All the child objects have the same name (“Plane”). The problem is when I select one unit all of the planes become visible.

The code:

#pragma strict

var selectedUnits = new Array();
var isSelected = false;
var target : Vector3;
private var selectableLayerMask = 1 << 9;	//Units
private var walkableLayerMask = 1 << 10;	//Ground
var hit : RaycastHit;

function Start () {
}

function Update () {	
	if (Input.GetMouseButtonDown(0)) {
		if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition),hit,200,selectableLayerMask)) {
			Debug.Log("Clicked on a unit");
			Debug.Log(hit.collider.name);
			AddUnit(hit.collider.gameObject);
			isSelected = true;
		}
		else {
			Debug.Log("Clicked on the ground");
			ClearSelectionList();
		}
	}
	
	if (isSelected) {
		transform.Find("Plane").renderer.enabled = true;
	}
	
	
}

function AddUnit (unitToAdd : GameObject) {
	selectedUnits.Push(unitToAdd);
	GetComponent(MoveUnit).targetPosition = transform.position;
	//transform.Find("Plane").renderer.enabled = true;
}

function ClearSelectionList () {
	selectedUnits.Clear();
	transform.Find("Plane").renderer.enabled = false;
	isSelected = false;
}

Can someone help me with this issue.

Thanks in advance.

Remove the lines:

if (isSelected) {
   transform.Find("Plane").renderer.enabled = true;
}

and put them into ‘AddUnit’, with a small modification:

function AddUnit (unitToAdd : GameObject) {
    selectedUnits.Push(unitToAdd);
    GetComponent(MoveUnit).targetPosition = transform.position;

    unitToAdd.transform.Find("Plane").renderer.enabled = true;

    // This bit was almost right!
    //transform.Find("Plane").renderer.enabled = true;
}
