New Lua Camera Control

I'm having a bit of trouble with the new SetCameraMode, SetCameraFocus and the old GetCameraMode. I may just be confused on terminology.

Firstly when doing in default, what I call first person view:


	Code: /lua print(GetCameraMode())

always returns zero. I get one and two in mouse look and appearance edit, respectively. I would expect those values from inspecting the enum in indra/newviewer/llagent.h. It seems there might not be a value for 'default, first person view' because it really is 'third person view'?

Secondly, I cannot seem to change to third person view with:


	Code: /lua print(SetCameraMode(0))

to change the camera, though the output is true when attempting. Using the values one, minus one and minus two do mouse look, default and reset (though I can't really tell the difference in those last two). Again, I may be confusing this mode with 'Camera Front View', debug setting CameraFrontView?

Finally, and this is probably just cosmetic:


	Code: /lua print(SetCameraFocus())

has no output though it does return the focus to my avatar when shifted elsewhere.

I'm using today's official build with the following:

This is the expected behaviour and reflects exactly how camera modes are implemented internally in the viewer.

You are confusing camera focus and camera modes.

The function works accordingly with the documentation, please re-read it and, again, do not confuse camera modes with camera focus... Basically SetCameraMode() is only useful to switch to and out of mouse look and to reset the camera view (like with SHIFT ESC).

This function never returns any value. That was a mistake in the documentation which I fixed now.

Re: New Lua Camera Control

Thanks Henri. I think I have always though of the 'direction' the camera was facing, first person...the back of my head and third person...looking at my face. In strict terms though, they are both third person, i.e. not out of my own eyes.

My misunderstanding, really. Sorry to create a message thread for nothing.

It was not for nothing, since I did indeed a mistake in the documentation, which I noticed thanks to your message.
