ok,I think there`s better to have a manual to describe how it work.

1.how to modding with it?

this mod is served as a core mod that allow player control "unit" and "deployer"("crafting_machine")

Prototype/Unit — unit
    "not_controllable":Bool
        Default:false
        this property disable unit control to actually control this unit,
        which make mining drone cannot be control by this mod,
        make it work properly.

Prototype/CraftingMachine — abstract
    "is_deployer":Bool
        Default:false
        this property make this entity selectable,
        and checking its output content,to ready output.

2.How deployer work?
whenever deployer compete a recipe,it will trigger this mod to check its "direction" and "output content",
and try to deploy a "entity" which that name.

for example,if you make a "assembling-machine-1" a deployer,
then if it crafting "burner-inserter" item,it will periodically deploy all "burner-inserter" in its output at target direction,
and "assembling-machine-1" only have north direction,as result,it will place alot of burner inserter at north of deployer.

bruh,accidently make more reply.

I was want to title it:
