I'm curious about this issue as well? Can we get some expeireced people to talk about their favorite mappers? maybe the programs that people like for 3d modeling and texturing?
I'm currently using a custom program as a mapper, I just set the cells in a matrix to various values, and if the cell is one value, I draw a box for a wall, if it's another, it's open floor, so on... I'm sure this is horribly inefficent, and it leads to basic looking levels, but its my first project.
Also if some one would start some posts on sliding collisions with plain objects, .x imported objects, matrix/terrain objects. This could be the hottest thread ever!
i love all you guys... really!
So many games... so little time!
