transform.localscale
Hi,
I have some questions I haven't been able to find the answers to yet. I'd like to find the height/width of a game object. I know that Transform.localscale will give me something similar, but as far as I know this is from the center of the object. I cannot find anything that will allow me to either get the height/width of an object or work it out via the scale.
Can someone please help?
You can use Mesh.bounds. This will be an axis aligned bounding box in local space. You will need to scale the box by localScale if you have a scale other than (1,1,1).
function Start() {
var bounds = GetComponent(MeshFilter).mesh.bounds;
Debug.Log(bounds);
}
Thanks for your comment, this seems to be what I'm looking for. However, I need a few more specifics. For instance, the second line (this maybe because I'm more used to c#) seems to be collecting a mesh filter but from somewhere I can't deter$$anonymous$$e. I have a gameObject setup in the constructor, the scale of which is different to 1,1,1 as you mentioned.
I'm guessing I'll need to create a new vector3 from the localscale which will be applied to the mesh. However, I'm not sure how I can get the mesh to apply to the specific game object I have created a code reference for in the Constructor; if that makes any sense.
Your help will be greatly appreciated, thanks for replying.
The GetComponent is using the game object the script is attached to. For C# you would get your size like this (untested):
Bounds bounds = GetComponent<$$anonymous$$eshFilter>().mesh.bounds;
Vector3 size = bounds.extents * 2.0f;
size = Vector3.Scale(size, transform.localScale);
Note that the extents are 1/2 the actual size.
