getVertex()

Purpose

Find the screen position of a vertex (point) in a shape

Description

Returns a vector describing the screen position of a desired vertex in a shape drawn with drawShape()

Syntax

position = getVertex( shape, vertex )

Arguments

shape Handle which stores the shape in question

position Vector describing the screen x and y position of the desired vertex

vertex Float index of the desired vertex (begins at 0, clockwise)

Example

gw = gwidth()
gh = gheight()

shape = createBox( gw / 2, gh / 2, gw / 2, gh / 2 )
coords = []

for i = 0 to 4 loop
    col = {random(1.0), random(1.0), random(1.0), 1}
    setVertexColour( shape, i, col )
    coords[i] = getVertex( shape, i )
repeat

loop
    clear()
    for i = 0 to len( coords ) loop
        printAt( 0, i, "Vertex ", i, " Screen Coordinate: ", coords[i] )
        if i == 0 or i == 3 then
            drawText( coords[i].x - 40, coords[i].y - 20, 40, white, i )
        else
            drawText( coords[i].x + 20, coords[i].y - 20, 40, white, i )
        endif
    repeat
    drawShape( shape )
    update()
repeat
