Blank screen in OS X El Capitan, errors in Processing

[Andrew-i2o3d]

Hi,

I'm trying to test MusicBeam on MacBook Air/OSX El Capitan with projector set as second monitor, and it's not working.

It's giving a blank/black main screen with no UI or anything at all.

I've tried opening the MusicBeam.pde in Processing, and installing the libraries as described in the readme file, and it gives errors when running in Processing which make me think one or more library is not loading correctly - eg. line 26 "Stage stage = null;" give the error "The class "Stage" does not exist", and likewise for many classes thereafter.

Any help appreciated.

Thanks,

Andy

Hi @Andrew-i2o3d,

do you happen to have a screenshot for me?

The error you are getting when running from source is strange. I guess there seems to be something wrong in your environment.

Make sure you have the code checked out clean, open the MusicBeam.pde file. Nothing else. It will open the processing IDE with tabs for all other files in that folder. If they don't show up, something is wrong.

Cheers,
Joe

Hi Joe,

Thanks for your reply.

Renaming the 'source' folder to 'MusicBeam' allows it to run in Processing, but the control window is always on the external screen (projector) and the effects on the main monitor, irrespective of the relevant preference setting. I could probably use it in this way of the effects were on the projector and not the computer monitor(!).

Re-saving it as a stand-alone application gives the same result as the downloaded MusicBeam - black main screen and ignored projector screen, with no UI anywhere. Escape quits it.

Attached are some screen grabs of main display and projector with MusicBeam app running, and Processing 3.2.2 with MusicBeam.pde open and running.

Cheers,

Andy

Hi can you change the 2 into a 1 at this line? This might help.

[Andrew-i2o3d]

Hi, makes no difference. I can set that number to any integer and it shows the effects on the main monitor and the GUI on the projector.

[codingjoe]

Hm... you should actually be able to move windows around using Mission Control.

Any update on this. Same exact problem. Running OS X 10.11.6. Only thing I can think of that im using Processing 3 instead of recommended 1.5 ...Tried installing that version but it wont even open. Please help.

[codingjoe]

Oh yes, where does it say 1.5? That's old news. You should use the latest version. Sorry.

@codingjoe Still getting black screen :(

[codingjoe]

@zombi3-h3ro black is good! That's the effect stage. The default effect is black-out ;)
Just switch to the controls window and select a different effect.

[zombi3-h3ro]

@codingjoe How do I switch to the controls window. As soon as I run the program, my computer screen goes to black and no controls show...My projector continues to cast my computer background. I would figure it would be the other way around.

[codingjoe]

@zombi3-h3ro that depends on your operating system. On mac you use MissionControl, on windows, Alt+Tab

[zombi3-h3ro]

@codingjoe THAT DID IT. Think it may have been working the whole time. That windows a phantom without mission control. THX x 1,000.
