Xpresso Counter ( How to make ? )

[Srek]

How do you want to define the timespan in which the counter shall go from 0 to 100?
The easiest way is to use a rangemapper node

every frame 1 count up

1 count up /frame

Try the attached example. Just set the Start Frame and Max Count user data values in the AM with the Xpresso tag selected. Result shown in Current Count and a result node in the Xpresso editor.

I added some clamping and modulo to prevent negative values and to allow wrap-around when the max count is exceeded.

Your version with the rangemapepr would be extremely interesting shrek,,, but how would you do it? Can u use the rangemapper to count every frame 1 value up to 100


JamesMk....
thx james very nice from you.
your solution depends on setting the starting time on a selected frame before

but how can i make this expression depend on the frame when i activate it

something like, activating > reading frame when it was activated > beginning count from this frame on

?
thanks

That would be a little more complicated. I would suggest looking into the Memory and FlipFlop nodes and see what you can come up with.

Otherwise, unless it's some prohibitively complex setup you need to use this for, you could simply keyframe the start frame value as you progress through the animation.

ok i will have a try, it would be just very interesting to know how to read the current time ( frame) only once.
Because normally the Time operator refreshes every frame.

Check this example (http://www.bonkers.de/forums/xpcounter.c4d). Since you only need a 1:1 frame counter the rangemapper is not needed, but for the enable logic some more nodes are needed.
