Thanks for the QR Michel, I tried including the fast within the forever loop, and DBN just ignores it… Ia also went into the preferences file and included the “slowdown=false” line in it, and nothing really changed. I did try what you mentioned on the online DBN about commenting out one of the loops and it worked wonderfully, that’s the reaction speed we’re trying to get at… I guess I’m gonna try to load the whole editor applet in the gallery and see if that helps any… I don’t even know if we’ll be able to do that, but we’ll try and I’ll let you know…

Thanks
Leon

Hi Leon,

I opened the page you mention and the speed seems fine to me. Note that it takes some time for the lines to appear from the top right to the bottom left because most of the lines (the A and B loops) are drawn outside the 100×100 square. Just to be sure, I copied the code into the online DBN editor at MIT, and after I commented out one of the loops and commented in again, then suddenly the speed increased phenomenally. It seems the ‘fast’ directive is ignored the first time the program is loaded. I don’t know how to work around this apparent DBN bug: maybe put the directive within the forever loop so that the interpreter is forced to take notice of it? Let me know if it worked.

Hi, I wrote to you a few weeks ago, now I bother you again with a new question. We’re trying to set up a gallery of pieces created in DBN for a class project, but the programs run super slow in the web… DO you know if there is anything we can do to alleviate this? all the codes do have “fast” in them.
here’s an example of what we’re uploading:
