Method Detail

initSpritePixels

protected void initSpritePixels(int turtleSideSize)

Initialize the turtle's pixels, an arrow. The arrow's geometry has a shaft either half the spriteHeight (for arrows with widths equal-to or greater than their height) or two-thirds the spriteHeight (for arrows whose heights are greater than their widths). The arrowhead is one-third the spriteHeight tall. The shaft's width is one-third of spriteWidth.
