Good day engineers,

I am attempting to create a bot to play factorio in Python with the use of reinforcement learning. But I am dealing with some dilemmas:

How can I move the player around? In mod API I did not find any command like "move(player, x, y)". Nearest I can get is a teleport. But moving is not all. What about placing entities? I did find command LuaSurface.create_entity but it is more like spawn not a simulation of player placement, so the item is not removed from players inventory and distance is also ignored. So I am looking for some way to control player through a mod API. EDIT: SOLVED

As far as I know, a mod can r/w to file which I can use to connect a bot (python) and factorio mod. Idea is that python writes command (in LUA https://lua-api.factorio.com/latest/) to file and mod reads this command from a file, execute the command and delete command. But I assume this approach will not perform enough as I plan to run factorio with game speed as high as possible. So my question is: is there any way to send commands to mod remotely?

Eventually, I can use direct x to send keystrokes to the game but I assume it will not be precise enough and use a mod to only receive information about the game like player and entities location and state.

Thanks for any advices.

The game doesn't have any built in API for building and moving, You will have to build it from constituent methods.

For instance building is just creating an entity and removing an item.

Moving is done by seting the walking state each tick: https://lua-api.factorio.com/latest/LuaControl.html#LuaControl.walking_state

Etc.
