Bounds.SetMinMax

Description

Sets the bounds to the min and max value of the box.

Using this function is faster than assigning min and max separately.

    // These represent the corners of the box in world space.
    // 'min' is the corner with the smallest X, Y, and Z values — typically bottom-left-back.
    // 'max' is the corner with the largest X, Y, and Z values — typically top-right-front.
    public Vector3 min = new Vector3(-1, -1, -1); // Bottom-left-back
    public Vector3 max = new Vector3(1, 1, 1);    // Top-right-front
