Therefore, here, I'll only list resources to get you started.
Notice: I call map the terrain (walls) only and call level the map + units + zones + everything else.
The Advanced Setup (accessed from Create Game in multiplayer) lets you :
• generate MP levels for all modes
• add and edit zones (but you can't see their name)
• add and position units
• save and load levels
The Level Editor (accessed by typing loadeditor(); in the console (which itself is opened by pressing the ` key) if you used advanced setup before, you must relaunch FS) lets you :
• add and edit high and low walls
• add, position and order units and waypoints around
• simulate a 100 seconds turn
• add and edit zones
• import maps (walls) from a PNG file
• save and load levels
Here are basic things to know before making a map.
Here is a partial guide for singleplayer levels and their zones.
In addition here's a quote from another thread, about mutliplayer zones:
Omroth wrote:For Hostage, you need zons prefixed with Hostage (ie Hostage1,Hostage2, etc) and Exit.
For Secure you need "Move2" (ie "Move2_A", "Move2_B") for the attacker spawn zones, along with "bidzone" for all the bidzones.
For Charge you just need "Move1" and "Move2" for the deploy zones, and "bidzone" for bifzones.
(You hold down "t" and move the mouse to create a zone).
If you want to learn more, open a campaign or level (psychoff/data/encounters/sp/) generated MP level, look what it contains and experiment.
Sharing your levels and maps:
If you're sharing anything it has to work for us, otherwise it's pretty much useless and a waste of time.
So once you have finished drawing your map, export it in PNG format, import it in the Editor and make sure it renders as you intended, also verify that units can go through most doorways. You can add enemy units and do a bit of simulation. After that it's time to save your level as a .enc file (encounter) and eventually play it against the AI via the Campaign which is a faster way than playing it in multilayer but you can't test all zones.
Once you're done testing, upload the .enc to the Modding section of the forum so we can play your level
You may also want to share the map, but the PNG will not be of much use, instead share your source file (ideally created in a 2D vectorial drawing software).
