Draw a polygon.
Following the mode argument, this function can accept multiple numeric arguments or a single table of numeric arguments. In either case the arguments are interpreted as alternating x and y coordinates of the polygon's vertices.
|
When in fill mode, the polygon must be convex and simple or rendering artifacts may occur. love.math.triangulate and love.math.isConvex can be used in 0.9.0+. |

Examples
Two ways of drawing the same triangle
This example shows how to give the coordinates explicitly and how to pass a table argument.
-- giving the coordinates directly
love.graphics.polygon('fill', 100, 100, 200, 100, 150, 200)
-- defining a table with the coordinates
-- this table could be built incrementally too
local vertices = {100, 100, 200, 100, 150, 200}
-- passing the table to the function as a second argument
love.graphics.polygon('fill', vertices)
