Hi guys,

How can I set the scale of my first person world ? I want to keep the map/objects in world coordinates and have it be 1:4, meaning a 1x1 floor tile in world coordinates would be 4 feet by 4 feet. When I make a hallway that's one tile wide (equivalent to 4 feet) it's really narrow and looks like maybe 1-2 feet, I can barely go down it. How do I take into account the size of my 'guy' ? All I can set is his eye (camera) height. Also, for a normal person should I keep the perspective set to pi/4.0f ? Thank you.

To force it to be 4 feet i would first have to define how many points big a foot is. Then figure out how many points big 1 tile is. After that I would change the scale of my world matrix to (PointsPerFoot*4)/PointsPerTile. As for your perspective question that depends on you. I think I can clearly see 90 degrees (pi/4), however if I had a huge tv, I would enjoy a higher fov because hey, who doesn't like seeing more stuff? This msdn article on setting up your perspective is pretty detailed without going overboard. http://msdn.microsoft.com/en-us/library/windows/desktop/bb205350(v=vs.85).aspx

I can't get it to work. If I set the world coordinates to be 1 unit = 48 inches (4 feet) and set the camera to a height of 1.33 world units (64 inches=average eye height of person) I can't go down a 4 foot wide (1.0 world units) corridor without the view cutting through the walls on the left and right. I hope I'm explaining that correctly. Thanks.
