i just started 3d programming and i was wondering how to find out the x and z coordinates of a level so i know where to stop the player at the edge of the map

have you tried dbSetCameraRange ( float fNear, float fFar )

The simplest way is to just check manually. Walk around as the charecter in game and see where you are when you arrive at the edge.

dbText(10,10,dbStr(dbObjectPositionX(charecterobjectnumber));
dbText(10,30,dbStr(dbObjectPositionZ(charecterobjectnumber));

There are likely better ways but it sorta depends on how exactly your level is constructed. Is it just one massive directx file?

If you have a level that is any more complex then a 2d rectangle though then manually writing in what x and z coordinates the player cant pass likely isn't a time effective way of constructing boundaries. Your probable going to want to set up some form of proper collision checks. Sparky's collision dll is great for that. http://forum.thegamecreators.com/?m=forum_view&t=74762&b=5

ok i figured that out. i made a test level with some ground and a box and i was wondering if there is a way to select just the box in dgdk its just one .3ds file
