Controlling The Tempo

Since the introduction of BPM for setting the speed of an effect, it is possible to have very fast effects in MADRIX. Furthermore, using the Speed Master it is possible to increase the speed even more. And some effects can even be played backwards. Several static effects, like SCE ColorScroll, may also be controlled via their frame ID. It enables the user to "scroll" the effect to a well defined "position".

All those things can also be done with an effect written in MADRIX Script. But the script author should take some precautions. This chapter describes what is necessary in order to have a script that can be run very fast or even backwards due to the Speed Master. A deeper insight into the topic FrameId is provided as well.

All the relationships will be illustrated with the help of a simple script, which moves a rectangle from left to right, or backwards.
