I've messing about with CP and OpenGLES. Started out with using co-ordinates in this form.. (Try an ignore how rubbish these diagrams are. The origin is in the centre of the screen.)
Code: Select all
1.0
|
-1.5----------1.5
|
-1.0
I've altered the values and those of objects drawn to use this system now.
Code: Select all
16.0
|
-24.0--------24.0
|
-16.0
Any ideas?
