MovableText

Hi!

I am working on a PyOgre based client for my game project called Thousand Parsec ( http://www.thousandparsec.net/ ). You can see some of the progress of the client with the screen shots of the (simple) results here -> http://darcs.thousandparsec.net/tp/scre ... tarmap.png

However I would like to display text below each Star displaying their names.

From the #ogre3d channel I was recommend to do a search for MovableText and use that. However nobody could point me to a link and the only code I found was for a much older version of Ogre (before they used SharedPtrs). I tried converting it to the current Ogre and wrap it with SWIG but it just segfaults.

I also tried rendering it to a data string using another library (pygame), but I couldn't figure out the correct way to load it and display as a material.

I also tried rewriting the whole the whole class in Python but it appears that the RenderOperation needed by the code is not wrapped.

Any ideas on what I could do?

Both seems like such a simple problems (much simpler then loading 3d meshes etc) but it sad Ogre has not easy support.

Thanks for your help.

You could dynamically create your own overlays (one per star) and position them using some sort of Entity.GetScreenCoord() or something to position it, there should be something like that.

Just a suggestion.

Overlays won't work because they won't be obscure by other things in the world.

It actually turned out that Overlays work pretty well. It's a lot slower then I would like but still usable.

It turns out that I want the text to stay the same size even when the objects are really tiny.

Thanks for pointing me in that right direction.

mithro, I'm trying to do something similar with my game. How did you determine the X, Y screen coordinates of the given entity?

Is there something within Ogre that already calculates this, or did you use something similar to the conversion thats in MovableText?

There's a patch here to implement OgreMovableText from the DSISceneViewer, with a simple demo. Not very pythonic though.
