How to add new custom unit???

[bluelaser]

I copy some unit file and rename it. I edit the name and class name in script.lua , and edit the Categories and FactionName in bp file. Add the icon file.
But when I enable this mod and enter the game and open the factory build UI,I found the custom unit is missing . I learn the structure of blackops mod and add custom unit folder with lua file. But the mod still didn't work. I go to study the TotalMayhem mod files and add the hook lua files(gamecommon.lua,unitview.lua and uiutil.lua), then fail agin...
Pleaser help me!

Hello bluelaser,

welcome to the FAForever forum

It's hard to say what's wrong with your unit. without seeing the code and blueprint.

If you want, you can upload your mod and i will take a look at it.
In case you are sure the mod is working you can also just upload the unit (folder).

Post the mod, then (Uveso ) can look at it and tell you what you did wrong

EDIT: Ninja'd by the master...

when a unit is missing completely, that probably means one thing - error in the blueprint file. The engine can forgive an error in the script file ( the unit will be there but the script part will not be working), but if the blueprint is corrupted (for example, you forgot to put a , where there should be one), then you will not see the unit at all.
This can easily be detected by looking at the log-there will be a warning concerning your unit, saying which file for that unit did not load, and the line number where that error is located within the file that did not load.
