hello

I have a problem, I would like to stop the timer when I press a key.
I know I need to use the function "keyPressed" but I can't do it... Can you please help me?
Thanks!

hi guys

could you explain me what is the interest of using IR LED when you make a ReacTIVision project?

hello guys

I would like to stop the timer in a program but I don"t know how... do you have any idea please?
thanks :)

hi guys

hello

does anybody knows how to manage Simulator with Processing? I have a problem with the field and I would like to make changes but I can not find the variables that it manages on processing.

thanks

Hello guys!

I have a problem and I can't find the solution.
Actually, I don't find how I can select a fiducials and check its position (with TUIO simulator). I want to match a fiducials to a planet of the solar system, and I have 9 planets. So, I need to identify each fiducial and each planet (with its coordinates) to check if the player has matched the right fiducials with the right coordinates .
If you have an idea let me know about it please ;)

thanks
