Available since LÖVE 0.9.0
This function is not supported in earlier versions.

Checks whether a polygon is convex.

PolygonShapes in love.physics, some forms of Geometry, and polygons drawn with love.graphics.polygon must be simple convex polygons.

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
