((In short (if you don't want to read the rest of this post) I'm looking to get the "static final int sqdim = 80;" line of code below to decrease by 10, every 10 seconds). Is this possible?))

Hey guys. . .I found this nice, and rather simple patch on the open processing website.

http://www.openprocessing.org/visuals/?visualID=10820

It's by a user called Daniel Simionato.

It's a series of simple squares but basically I have taken it and made it bigger (by changing the size resolution). However what I'd really like to do is have the size of the squares (i.e the amount of squares on screen increasing) get smaller in number every 5 or 10 seconds but I'm having trouble figuring out how to do this.

I have made 10 videos altering the size of the square (i.e making them smaller and even increasing the padding) that I could edit together in Final Cut Pro - however it's much less messy is I could just have one long recording of the squares getting smaller and thus increasing the number of squares. Does anyone know how i'd go about doing this?

I'm not looking to take credit for this patch - I'm merely going to record me playing with it and then compose some sounds for it (to play as the recording plays - not interactively).
3. static final int sqdim = 80;
4. static final int winwidth = 1280;
5. static final int winheight = 720;
6. static final int numsqrow = (winwidth/sqdim);
7. static final int numsqcol = (winheight/sqdim);
8. static final int sqpadding = 5;
9. static final int fadevel = 10; //fading velocity
10. static final int randomness = 255;
11. static final int randbase = 16; //base value, to avoid "flashing" squares (squares that change colour too fast)

Saving your application to a web page?

Hey guys,

I'm not sure whether this goes in this section but I couldn't think of another section other than Exhibition - and since I'm not showcasing a final piece at the minute this seems the best place.

Basically browsing this site it is clear that you can upload your application for people to use.

I was wondering how this is done?

I'm on a Mac and have an FTP server / website made in iWeb.

Do you "Export Application" and then select Mac. . .or do you simply "Export" (which creates an Applet folder).

Is there a way to make your final app a Java file so that you can just stick it up on your site?

Thanks a lot.

"Record" code?

Hey guys,

I am a Sonic Arts student and some of the apps created in Processing look great. I'd like to take some of the interactive ones and record what's happening on screen and export it as a video that I can compose to - is there a piece of code I can add that allows such a thing?

I'm thinking about one of the Apps that when you click, there are particle effects. I'd like to record the program as I run it and make particles move and have a final video that shows exactly the images.

Thanks a lot,

Aaron.
