<p>Create a separate page for each callback</p> <p><b>New page</b></p><div>== Length of animation frame (20/27/142/154/15A) ==<br /> <br /> Called to decide how long the current animation frame should last. The value of the delay should be given in the same way as for property 1B/10/17. Decreasing the return value speeds the animation up instantly. Increasing, on the other hand, doesn&#039;t slow it down instantly: the actual duration of the current frame will be somewhere between the old and the new delays. The new delay is applied correctly for later frames.<br /> <br /> Note: This is one of the most time consuming callbacks as it is called for every animated tile every ≈30 milliseconds. For better performance try to avoid using it where reasonable, e.g. try to use only the properties and put multiple identical looking animation frames after each other.<br /> [[Category:Callbacks]]</div>
