Im not too familiar with the game, but i think its really simple. The items and ability that you will need to fool around with are the item "Tiny Farm" in the miscellaneous folder. And the ability "Build Tiny Farm". Just copy each of those abilitys, and paste them. Then edit them as needed.
First, before anything, create a new unit..just base it off the farm. Now you will have to change the name, text, icon, and stats as you want. A barricade with 500 health isiant the best...you may need to fool around with the collision size, as it will be turned into a barricade. Also, you will have to change the model of it to the barricade and the cooldown that its built, as thats how fast it will be made after being placed down.
Next, you should edit the ability, build tiny farm. If youve already copied as above, that dont worry about it, but if you havent, copy the ability, and paste it, as youll be editing that one. After thats done, you dont have to change a lot here, just need to change the name, icon, and Data - Unit Created, youll have to change that to the newly made barricade. Im not familiar with this, so you will have to mess around with the number listed to meet your desired result.
Finally, you need to edit the item. Change "Ability - Abilities" to the newly made ability, invalid, text, icon, and whatever else ya need.
And..that should be it. As ive said, im not too familiar with the game, so if theres something i missed that the makers added just state so.
