Im halfway through doing a very basic model of a house, rooms windows doors and all that and wanted to know if there is a way i can then make the camera move in realtime by using movement keys on your heyboard, like wasd in games? Basicaly i want to set it up so that anyone can come along and walk through this house, maybe make it so you can open and close doors but ill leave that for now, just want to be able to move the camera. I really dont know what im doing with this side of blender so would greatly appreciate some help. Thanks

I made a bullet engine compatible walkthrough template some time ago. This one will work correctly with 2.42.

You can get it here: http://blenderartists.org/forum/showthread.php?t=80406

The official walkthrough template can still be downloaded on blenders site: http://www.blender3d.org/cms/3D_Walkthrough.340.0.html

However, they didn’t update it to be used with the latest blender versions, so for now just use my setup.

wow, thats pretty good, thanks. so would it be easiest to delete everything you have othr than the camera and empties, put them on another layer and build up my house thing to avoid me having to re come up with all your settings? also is there any way to play this without having blender installed on your computer?

Yes, you should delete all the crates and the ground plane (things you don’t need), then if you have your mesh/s in another blend file, you can import them with “File->Append”, to the template.

To make a binary, you do “File->Save Runtime”. Then make sure to have a copy of both “SDL.dll” and “Python24.dll” in the same directory where your binary resides (you can find both of those dll files in the main blender directory. If you don’t know where that is, just do a system wide search for both files, and copy them to a folder holding the binary that way.)
