Tween library - 2 Tween instances crashing sketch
Jan 23rd, 2010, 6:17am  
Hi.
I'm working on a simple user interface that is controlled by arrow keys.

I use the tween library for smooth transitions.

The library and the transitions work fine as long as i use just one instance of the Tween object. As soon as I add another instance, it causes the sketch to crash, producing an error.

working sketch with only one instance of Tween, problematic line commented out.
error message

How do I fix this

I like what youre doing with the library, thanks for posting this could be used as a good example! The problem is how your passing the PApplet object into the Tween object. Its best if you make a seperate class called main or something which you can instantiate as an object using new... and pass to the Tween object.

Thanks for your hint. I haven't yet figured out how exactly your suggestion translates into code, so could you please post an example of this? thank you.

heres an example which takes an object named rect and tweens some of its parameters...

http://ekeneijeoma.com/processing/tween/examples/Tween_TweenObject/applet/

you can use any object of a custom class you've written to do the same. so you have to write a custom class, overlaymanager which "manages" a list of overlays. then you can pass the overlaymanager to the overlay class and use overlaymanager to as an object and not PApplet which is return by calling this classThis() in your sketch...
