Runtime error on moveCamera / lookAt
« on: November 09, 2012, 09:15:28 am »
Hi,

i have made an app like HelloWorldAe.
When i compile this app it is ok but at runtime there is an error by moveCamera, lookAt or setPosition method.
If i comment out the lines with moveCamera, lookAt and setPosition then it's fine.
I have tested the HelloWorldAe example too and there is the same error.

Currently i'm at work. I post the error log when i get home.

On line 83 is
Code: [Select]

It's impossible to tell without looking at the exception's stack trace. Might be that it simply can't find the class files. If that's the case, look here for a solution: http://www.jpct.net/forum2/index.php/topic,2663.0.html

I have solved my problem.
My mistake was that i called world.getCamera(); but getCamera return the Camera object so i got an empty Camera object.
