What does it mean by camera number?
Doesn’t it means I can create more than one camera?
Yes, you can have multiple cameras.
Just pick a number for the camera, and fill the layer field to assign a layer to that camera.
How to assign?
Can you please give a simple screenshot?
Here’s an example:
I’m assigning layer boulets to camera #7 and making it follow camera #0 on the Y axis.
Multiple camera is a rest of multiple camera support than was in GD4 native games. They are not supported (yet?).
See this post for continue the discussion.
There are some Interesting proposal.
