Find Size of GameObject

Questions & Answers
1

Hi there,

I would like to know how to find the size of an object. eg vector3(10.0f,10.0f,10.0f); gameOjbject.size:vector3

What code would I have to use to find the total size of a GameObject? How would I do it.

Thanks

If the object has a renderer, then renderer.bounds.size will give you what you want

Next best thing would probably be collider.bounds.size

The correct code for recent version of Unity is:

GetComponent<Collider>().bounds.size
GetComponent<Renderer>().bounds.size

transform.bounds gives you the global size, axis oriented.

if you want the REAL size of the object, ignoring the transformations done to the object, use mesh.bounds which gives you the local size of the mesh.

I believe the correct Unity5 code is:

GetComponent.<Collider>().bounds.size
GetComponent.<Renderer>().bounds.size

The ‘.’ before the requested component is needed.

For 2D sprite:

var p1 = gameObject.transform.TransformPoint(0, 0, 0);
var p2 = gameObject.transform.TransformPoint(1, 1, 0);
var w = p2.x - p1.x;
var h = p2.y - p1.y;

This works whether or not the item is active.
