A smaller delta can make the movement smoother but also present the CPU with a heavier load. <dt><b>now</b> <dd>The "current time" in the animation. For every frame, the position and size of each object is calculated at the time now. If no tick matches now exactly in the object's script, the values are interpolated from the surrounding ticks. </dl> <hr> <address>Ulric Eriksson - July 1997 - ulric@siag.nu</address> </body> </html>
