robots816, the easiest way to test your map is to use a batch file:
1.open notepad and type:
cd (type the path of teeworlds here eg C:\folder1\folder2\folder3\teeworlds)
teeworlds_srv "sv_map [type your map name here with out the braces]" "sv_gametype [put game type here]"
2.goto save as and change save type as to "all files" then name it anythingyoulike.BAT
3.Save it and then execute it.
4. if done correctly command prompt should open and you should see a load of text.
5. execute teewrolds and goto "LAN" you should see your game {if you cant see it try unticking game types , has people playing , etc}
6. if you still cant see your game. you prob messed up the batch file.
7. if you messed up the batch file then remake it (make sure to put the exact path of teeworlds , etc)
8. oh yh make sure your map is in the map folder in data folder in your teeworlds directory
9. hope this helps? / if you need any help just let me know.
