createPoly()

Purpose

Creates a polygon to be drawn with drawShape()

Description

Creates a polygon with centre origin to be drawn at the specified x and y location with the specified dimensions and number of points

Syntax

shape = createPoly( point1, point2, ... pointN )
shape = createPoly( points )

Arguments

shape Handle to store the newly created shape

point1 Position vector for the first point of the polygon

point2 Position vector for the the second point of the polygon

pointN Position vector for the Nth point of the polygon (you can create any number of points)

points Array of vectors describing the desired points of the polygon

Example

// draw a multicoloured irregular 4 sided polygon on screen
w = gwidth()
h = gheight()

points = [
    { w / 3, h / 3 },
    { w - w / 3, h / 3 },
    { w - w / 4, h / 1.5 },
    { w / 8, h / 2.5 }
]

cols = [
    red,
    green,
    blue,
    bisque
]

shape_1 = createPoly( points )

for i = 0 to len( cols ) loop
    setVertexColour( shape_1, i, cols[i] )
repeat

drawShape( shape_1 )
update()
sleep( 3 )
