Proper way to implement a camera?

[R Blau]

What's the suggested way to implement a large 2D space that can be panned through?

I achieved it with stage.setTransform(..) and it feels nice, but I noticed that Mouse Events for objects on that stage don't work as they should. The clicking area stays on its original place when I move away the viewport.

Is this a bug? Am I missing something here?

Hi,

Do you want to pan the whole stage, or only a smaller part of the stage (like window)?

If you only want to pan a smaller part, you can use the ViewportContainer display object.
https://github.com/bp74/StageXL/blob/master/lib/src/display_ex/viewport_container.dart

If you want to pan the whole stage it is very easy:

var panningSprite = new Sprite();

stage.addChile(panningSprite  );

now add all your display objects to the panning sprite and move it:
panningSprite.x = 100; 
panningSprite.y = 200;  

hope this helps,

Bernhard

Yeah, that's exactly what I needed (to pan the whole stage). Thank you very much!

Certainly looking forward to work with this library. Seems very promising so far.
