Hope this is the right forum, anyway this is my first piece of processing beyond just "ohh look a line" so its probably quite a mess and maybe a few things I don't need but anyway works as intended in the enviroment but only the drawing works in a browser.

Anyone got any idea why? Cheers

left mouse:draw
right mouse:delete

Thanks for the reply, tried moving that in to setup but I get
"Semantic Error: No accessible field named "drops" was found"
as soon as it reaches
Code:

"drops[numdrops] = new Water(200,0);" 

at the start of draw.

Ahh yeah I see, that one works the same in the dev environment. However the same result when exported, drawing and deleting works but no water.

and to add to that, you may need to flush your browser's cache, or the java applet cache, and/or quit and restart the browser completely because it may be using the broken version of your code even after re-exporting.

or simpler, try changing the name before the next export.
