Error with Processing Beta 4 implementation

[.lov.]

Hey,

just trying to send frames from Processing 2.0a6 using the Beta 4 version of Syphon-Processing. When I start the sendFrames example, I got the following exception:

java.lang.NullPointerException

Some other informations:

– the issue is happening on both 10.6 and 10.7
– with Processing 2.0a4 everything is perfect.

Seems the newer Processing alpha has some API changes.

Thanks for the report – if you have the know-how feel free to submit a fix. I’ve opened this as an issue on the implementations project:

http://code.google.com/p/syphon-implementations/issues/detail?id=19

Unfortunately I have no experience with library creation for Processing, but as far I see the PTexture class now exists as Texture. I think this is the issue, but its just a tip.

Okay, I gave it a try, and fixed the issues happened by API changes. Now the app running, however, I can’t send or get frames from or to Processing. What I get is always a blank frame.

Since I don’t know really much about Processing under the hood, I cannot find what cause the issue. If someone wants the modified source code to take a look into, let me know!

Yo

New download is available for Processing 2

Thanks for the heads-up, it works great!
