[SOLVED] trigger every 10th frame

[Jesper Rahlff]

hey guys.

simple question which I do not hold the answer to.

I have a switch and I want it to switch input number every 50th frame going between 0 and 1.

so example would be that for the first 50 frames the active switch value is 0 and then on frame 51 it goes to 1, hold that for 50 frames and then turns back to 0.

I need this to be a procedural expression if possible rather than key framing it.

 

Thanks

this expression does it (floor(($F+50)/50)%50)%2

but I'm sure there is an easier one. I even remember a thread here on odforce where I posted the solution but it was a long time ago and I can't find it anymore..

 

EDIT: found it! In your case it would be $F%100<50

So we can say that if you need to turn something on (= 1) every n frames for a certain duration (num_frames_turned_on)
the general form is $F % ( every_n_frames + num_frames_turned_on ) < num_frames_turned_on

just messing around, also found this to work: 

floor(fit($F % 101,0,101,0,2))

old thread but really helpful. i want to do the same but with a small difference. when i want to change from 0 to 1 i would like the change to be smooth

0000 0.25 0.5 0.75 1111 0.75 0.5 0.25 0000
