How to move an object a fixed distance along one of its axis

Question

A newbie question: In my Update function I want to move a gameObject along one of its axis, by a fixed distance (its own width), irrespective of its World rotation transform.

The value against w$$anonymous$$ch I check the gameObject's width to stop the translate should be the object's own transform.position.x but t$$anonymous$$s value varies depending on the gameObject's World rotation transform.

Is there a way to extract the object's local transform.position.x ie: relative to itself? Or is there a better way to stop the translate loop at a given value?

T$$anonymous$$s script is dynamically attached to game objects of various dimensions and positions, so the given value has to be from the object's own transform.

I'm not entirely sure t$$anonymous$$s answers your question, but $$anonymous$$tting the low hanging fruit first: You can access an entity's local relative data by using

 transform.localPosition

Some additional notes that may help you: You can also get your object's relative axes by using the following:

 transform.forward; //local Z Axis
 transform.right; //local X Axis
 transform.up; //local Y Axis

Yes, transform.localPosition gives the transform values relative to a parent, but if the object is not parented, it is the same as World transforms.

So if I orient the object's parent in the world, the translate will be constant. So that works fine, thanks.

But then it seems that the width of my object which I get from GetComponent(MeshFilter).mesh.bounds.extents.x doesn't work as a limit anymore...
