I am printing out a box collider’s size (collider.size), and its bounds size (collider.bounds.size). They give me two distinct values:
“=> (0.6, 0.4, 0.5) vs (0.4, 0.4, 0.4)”
I have made sure that the object is not in some strange transform or anything (since I know the collider.size is represented in local space). I have also tried converting the collider.size to world space and still the same discrepancy. Is this known/expected? Is the collider’s bounds more liberal on purpose?
A BoxCollider’s size is expressed in local space; its bounds are an axis-aligned bounding box (or “AABB”) expressed in world space. If your box is scaled or rotated, the two values will not necessarily agree.
As you might infer from the above, an object’s AABB will always be at least as large as its actual size.
BoxCollider2D collider.bound.size is change when your are scale or rotate game object it will change the bund size value. In collider.size is depends on only size value shown in inspector.
