OpenRA

Newbie in modding here. Tried to make a new unit and building in red alert
I copied the aagun and called it agun2 I also copied agun sequence and called in agun2 but when I fire up the game I get the error below.

You probably need to define in the rules of your agun2. It is hard to tell without seeing the entire yaml though.

Thanks, where would I "define" it. Sorry if this seems stupid.

I did the same method in dune2000 and it worked so wonder what is missing when I do this is ra

Somewhere under agun2
