Modding in new Buildings

How could I mod in a new building, I want to add a tower that slowly heals all nearby units. It would be buildable by commanders and adv-fabbers. Has anyone here modded in a building before? Also how could I create custom behaviour for my building?

Also, first post!

There is something similar going on in this thread. No definite results yet though.

Custom is a limited term. However, it sounds like you could take a single laser tower, change the weapon to a combat fabber's weapon, and give it a large range of like 150-250.

Take some server mods that add units. Use them as a framework of how a server mod works. Read up on it. From there, just note that the combat fabber's build arm in their folder (or possibly in the "pa/tools" folder), can copy pasted into the single laser tower's weapon .json with notepad, and pretty much work instantly. It already specifies "auto repair in range" and you would have to turn up the range value.

Also, as denim pointed out, the structure apparently needs a navigation field. Just copy another unit's "navigation":{...} area and paste it into the single laser tower, and give it movement values of 0. Oh, also, give it "Command Caps" like a base_commander's command caps, that is what give the unit it's sidebar. Give it assist, reclaim, repair, and patrol. Obviously don't give it fire-secondary and "move".

Something i made for me, double laser tower with autorepair.

If you set it on patrole, it supports factorys or constructing

Weapon base is the advanced bot fabber

Edit: picture

"UNITTYPE_CmdBuild", to let to commander build it

Thanks for this! But what about also making another (new) unit able to build it as well, but ONLY that unit and commanders?

fabrication bot
"buildable_types":"Land & Structure & Basic | Factory & Basic | Factory & Advanced & Bot & Land | FabBuild",

maybe you need to create a new unittype for your bouilding and add it to the buildable types

just an idea, dont know if it works

You can't create unit types, but you can use custom1, custom2, etc for it.
