spotLight()

Purpose

Create a spotlight light source in 3D space

Description

Creates a spotlight source in the specified position of the specified colour, brightness and with the specified spread angle

Syntax

handle = spotLight( position, direction, colour, brightness, spread )

Arguments

handle handle of the light source

position A position vector in 3 dimensional space { x, y, z } where the light source is located

direction A vector to describe the direction in which the light is pointing

colour colour name or RGB values { red, green, blue, opacity } between 0 and 1

brightness A value to indicate the brightness of the light source

spread angle (in degrees) of the spread of the light

Example

setCamera( { 0, 6, 10 }, { 0, 0, 0 } )
spread = 50
light = spotLight( { 0, 4, 0 }, { 0, -1, 0 }, white, 100, spread )

obj = [
    placeObject( cube, { 0, 0, 0 }, { 4, 0.1, 4 } ),
    placeObject( cube, { 0, 1.1, 0 }, { 1, 1, 1 } )
]

setObjectMaterial( obj[0], white, 0, 1 )
setObjectMaterial( obj[1], cyan, 0, 1 )

loop
    c = controls( 0 )
    spread += c.ly
    spread = clamp( spread, 0, 100 )
    setLightSpread( light, spread )
    rotateObject( obj[1], { 0, 1, 0 }, 1.0 )
    drawObjects()
    printAt( 0, 0, "Use Joy-Con left control stick adjust spread: " + spread )
    update()
repeat
