Example

image = loadImage( "Untied Games/Enemy A", false )
enemy = []
for i = 0 to 4 loop
    enemy[i] = createSprite()
    setSpriteImage( enemy[i], image )
    setSpriteAnimation( enemy[i], 0, 4, 20 )
    setSpriteLocation( enemy[i], { ( i % 2 ) * 400 + 400, int( i / 2 ) * 300 + 200 } )
    setSpriteScale( enemy[i], { 4, 4 } )
repeat

loop
    clear()
    // updateSprite(enemy[0])                  not updated  
    updateSprite( enemy[1] )                  // normal speed
    updateSprite( enemy[2], deltaTime() / 2 ) // half speed
    updateSprite( enemy[3], deltaTime() * 2 ) // double speed
    drawSprites()
    update()
