setVertex()

Purpose

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

Description

Used to change the on-screen position of a vertex in a shape drawn with drawShape()

Syntax

setVertex( shape, vertex, position )

Arguments

shape Handle which stores the shape in question

position Vector describing the desired x and y position of the supplied 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 = []
col = {}

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()
    j = controls( 0 )
    coords[0] += { j.lx, -j.ly } * 10
    coords[2] += { j.rx, -j.ry } * 10

    setVertex( shape, 0, coords[0] )
    setVertex( shape, 2, coords[2] )

    drawShape( shape )
    printAt( 0, 0, "Use the left control stick to adjust the position of Vertex 0" )
    printAt( 0, 2, "Use the right control stick to adjust the position of Vertex 2" )

    for i = 0 to 4 loop
        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

    update()
repeat
