Gets the bounding box of the shape. This function can be used in a nested fashion with love.graphics.polygon.
Function
Synopsis
A bounding box is the smallest rectangle that encapsulates the entire polygon.
x1, y1, x2, y2, x3, y3, x4, y4 = Shape:getBoundingBox( )
Vertexes are returned starting in the top-left in a counterclockwise fashion (top-left, bottom-left, bottom-right, top-right).
Arguments
None.
Returns
number x1- The x-component of the first vertex.
number y1- The y-component of the first vertex.
number x2- The x-component of the second vertex.
number y2- The y-component of the second vertex.
number x3- The x-component of the third vertex.
number y3- The y-component of the third vertex.
number x4- The x-component of the fourth vertex.
number y4- The y-component of the fourth vertex.
