Hi there - I have a program which creates particles and has them floating on screen. What I would like to do is update the number of created particles through a slider in the GUI. I've tried a few things but I can't get it to work, I got it to work once but a new particle system was created every frame so not too useful..
If you have any ideas or places I could look it would be greatly appreciated!
you should post your code or a mcve of your code
anyway, maybe you want to look here:
(I guess it's for processing 1 / 2)
that doesn't sound to good
actually, you should start the particle system in setup() and then run it in draw()
so in draw read the values from the sliders (or read the values in the event functions, store them in a global var and that var gets used by draw())
Hi Chrisir, thanks for the comments!
I've uploaded the sketch here, name of sketch is "Sketch_02_GUI". There are some classes in there also.
I can control the threshold for when points are connected but not the number of particles in the running sketch. What would you recommend? - Thanks!
well, compare the number of the particles with the number the GUI gives you
then either append items p or remove items
this would be easier if p were an ArrayList but never mind
for append iirc
