Get the world coordinates of the polygon's vertices.
This function has a variable number of return values. It can be used in a nested fashion with love.graphics.polygon.
Function
Synopsis
x1, y1, x2, y2, ... x8, y8 = PolygonShape:getPoints( )
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.
And so on, for up to eight vertices.
This function may have up to 16 return values, since it returns two values for each vertex in the polygon. In other words, it can return the coordinates of up to 8 points.
