New to D2k modding?
It's kind of a hassle to add new units in D2k. You may need to replace pre-existing stuff to get the new turrets you desire. You can add a new TYPE of building, but adding new structures in the list on the right will cause shenanigans.
Try setting one of the Rocket Turrets to be owned by all factions, then change one of the other Rocket Turrets to the sort you want. You'll need to give it a new building type in the list on the left. That will work just fine.
trying to add another rocket turret (shooting sonic tank gun) causes game to crash. i am using the modded templates.bin from the there ,opened the map editor,launched structure editor and added new large turrets for atreides/ordos/harkonnen.. they are all just copiesof exsisting ones but just changed their weapon.. but game crash if i try to place it.
what i need to modify yet?
and did you try downloading the "windows 10 fix" from gruntmods webpage? I cannot say you too much options besides that and using the config.exe and trying with multiple configurations. I have been playing with gruntmods since, 8-10 years by now, with a few formating here and there and changing S.O and the game worked on Xp, on 7 and on windows 10 just fine.
Make sure you copy a .map file, a .mis file and a .ini file into Data/maps, as Fey said above. You need all 3 files AND they have to be in Data/maps for it to work. The CnCNet client also has to be restarted if you copied the files while it was open.
By the way, we are all assuming you're using the CnCNet client to play skirmish. If you aren't and you are asking about how to add the maps so you can access them straight from in-game's Practice menu, then the answer is yes, it can be done, but please don't, that is a very outdated way of adding skirmish maps to the game which is no longer needed since around 2015. The CnCNet launcher can provide everything the in-game Practice menu can, plus a bunch of other cool features such as different individual AI difficulty levels or higher starting cash options PLUS 8 player support AND the fremen (gray) and ixian (light brown) colors.
