Oh and the Sven coop map i am thinking of is a defense map. If anyone has a work around this wad and rad compile problem please let me know! :) I was thinking of using the stand alone game to compile and test my maps then transfer the maps across to the steam apps folder so i can run it through steam. I have also installed the original half-life game from CD and compiling the maps gives me no problems at all, i can compile and run and test but when i try using the Steam half-life game it completely screws up :( Can not find the WAD files ( i was told to put the wad files on the same drive as the Editor, i have done this but still get the error.) I am currently trying to create a Sven coop map for the game Half-life, however i can't seem to get the setup right when i try to compile the map through Steam HL.exe.ġ.
