Touchdesigner - Equivalent in processing - Realtime button

Sugarbank

Hey guys, Just wanted to see if there is a similar functionality in processing where processing will wait until an entire frame is "cooked" until moving onto the next frame.....without trying to maintain real time playback. Basically the functionality of the realtime button in TD

Trying to write out frames with out the skletch running in realtime, however having the same result. Cheers oin advance

Thanks GoToLoop. If the sketch is running approx 30fps when set frameRate(60)...

Then if I want a stable 25fps output(saveFrame) would I use
noLoop() and then millis to call redraw() (millis() > 40) ? Also What function would I put this under though as it can't exist in the draw()

GoToLoop

• noLoop() puts the sketch's frame refresh on a trigger driven state.
• That is, the canvas is refreshed once per demand via calling redraw().
• Generally redraw() is invoked by user input callback functions, such as mousePressed() or keyPressed().
• But other events can be used as well, such as serialEvent() or movieEvent(), which are controlled by a separate Thread.
• We can also make our own Thread and invoke redraw() on demand from it.

Or you can just put your time trigger in draw. I also agree, the movie event would be a great place for you. However, I don't know how accurate would it be when it comes to get it down to 25fps consistently. It shouldn't be hard to test.

Hi kfajer....just wondering what you ment by "time trigger in draw"?Cheers mate

@Sugarbank Something like this if (millis() - startTime > DISPLAY_DURATION) in the following post: https://forum.processing.org/two/discussion/8084/how-do-i-display-a-message-for-a-few-seconds
