Load XML file in the background
Jul 20^th, 2009, 11:15am

Hi.
Is it possible to load an xml file in the background without slowing down the draw loop?

For example, I want t write a programme that loads an XML file from the internet when the user klicks on a moving object on the screen. If the xml file is too large, the moving objects will stop until the file is loaded. Since the I the URL of the XML file is influenced by the user, i can't load it in setup().

Is it possible to avoid this break?

stuff i do

Not really, threads are really simple: put computation in a function, run it in a thread...

Now, what is hard, is how to use the result of computation (update once it is computed), how to share data between two or more threads, how to synchronize threads, etc.

I think there's something fundamentally fishy with my threading. So please post your code when you're done, I'll sure like to see it.
