Hi, I think I already know the answer to this, but will ask it anyway

Is there anyway to show the current X,Y,Z axis when playing the game based on current camera view in 3D view ? If not, would be a useful display function to add - useful for debugging purposes.

Yes... and no.
There is no built-in Visualisation of the Data., but it's quite easy to model the axis (say in Blender or such); then essentially load it in at the X/Y/Z Position and Rotation... once you've done that use the "FixObjectToObject( Child, Parent)" to then not have to update anything else; the Engine will pretty much handle updating the Position and Rotation.

If you the SetObjectDepthWrite( Object, 7 ) this will ALWAYS Draw the Object... of course another approach is to hide it, and render it to another RenderImage; As once you're not longer rendering to it, you can use that on a Sprite (with a Transparency Key) and you have complete control over the depth of Sprites ... although I think the 7 Setting just ignores Depth and always renders the object on top.

Hi, maybe you are looking for this...

Print( "Xangle "+str(GetCameraAngleX(cam1))+" Yangle "+str(GetCameraAngleY(cam1))+" Zangle "+str(GetCameraAngleZ(cam1)))

Y rotation is displayed 0 to 360, Z and X are not and that can be a bit of a pain sometimes.

Here is a little demo code....
