How do I get bounds or width/height of grouped objects?
Hi, Is it possible to get height and width of grouped objects like this?
I tried boxcollider2d.bounds and renderer.bounds. Each shapes in the group has collider component.
Is it possible?
Basically, you need to loop through the bounds or vertices (depending on the level of precision and optimization you need) and get the min/max values for all of them in every dimension you use (Vector2 for 2D, Vector3 for 3D, etc). Something like this (pseudocode, won't compile):
Vector2 min = Vector2.MaxValue;
Vector2 max = Vector2.MinValue;
foreach(Object obj in AllObjects)
{
min = Min(min, obj.Bounds.Min);
max = Max(max, obj.Bounds.Max);
}
Then the min and max define an AABB that will bound all of your objects.
