Checks whether a polygon is convex.
PolygonShapes in love.physics, some forms of Meshes, and polygons drawn with love.graphics.polygon must be simple convex polygons.
Contents
Function
Synopsis
convex = love.math.isConvex( vertices )
Arguments
table vertices- The vertices of the polygon as a table in the form of
{x1, y1, x2, y2, x3, y3, ...}.
Returns
boolean convex- Whether the given polygon is convex.
Function
Synopsis
convex = love.math.isConvex( x1, y1, x2, y2, x3, y3, ... )
Arguments
number x1- The position of the first vertex of the polygon on the x-axis.
number y1- The position of the first vertex of the polygon on the y-axis.
number x2- The position of the second vertex of the polygon on the x-axis.
number y2- The position of the second vertex of the polygon on the y-axis.
number x3- The position of the third vertex of the polygon on the x-axis.
number y3- The position of the third vertex of the polygon on the y-axis.
Returns
boolean convex- Whether the given polygon is convex.
