I´m new with this program so i think that i miss something, in the AUM (97) I found a script of a shooter template, but when I change the wmb file, the player begins to "fly", to ascend, and walk THROUGH the walls, even if I just delete one build of the original wmp file and then compile,What´s going on?

be sure that you have "create meshes" checked in the map compiler

...or just click Default Settings in the build window before building

to see the "create meshes" option, you have to click the button ">>>" in the building window

Thanks I almost kill myself
