I am trying to create an animation module that will act as a power switch for a amplifier project I am working on. The module will have a switch to the amplifier and also run an animation of vacuum tubes warming up. It is based on work by philter5, (tubes), mwvdlee (nixie tubes), and tor (tubeglowshow). However, I want the animation to be automatic, to run when the switch is turned on. I have hacked together a simple time counter, but because it uses steps to the animation module, the animation is not smooth. When you toggle the switch on, the tubes "warm up" and start to glow. Then you toggle the switch off, the tubes "cool down".

Is there a better way of accomplishing this so the animation is still automatic and smooth? I have looked at the animated module by tuz, but can't seem to get it to work right for this application. I have posted a pic and osm (excuse the poor tube graphics, done quick and dirty in Paint.Net using glow effect).

here is a little example of a smoother animation. it uses the float slide primitive and you can adjust the step rate in ms and set the step size. another way is : you take two bitmaps, one is the tube when its cold, and the other shows the tube in it´s final warming stage. put the 2 images exactly over each other and modulate the alpha value from the top layer bitmap (the warm tube). this way you can create the whole animation inside sm, but i prefer knobman for this task...

Very cool! Thanks philter5, just what I was looking for. Much smoother animation and your approach seems simpler too.

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
