If I remember correctly, your question was about how to add an empty item to the undo stack that you could add things to later. The existing API lets you read and modify the undo and redo stacks, but does not let you create entries without invoking an action that emulates a player action that would ...

This is a terrible idea...

Just a heads up, starting a post in this manner might set the wrong tone. :)

I don't care if it's terrible. The game doesn't seem to offer a clean way of letting mods undo things. The devs give mod authors the silent treatment. So anything that works is a good idea ...

Use the C-style escape sequence "\n" (backslash n)

Probably because the the 2.0.56 package was malformed and they pulled it from the release channel. You'll have to manually update to 2.0.57 from whatever version you are on now.

What did you do?
1. Place a non-player character entity inside a car.
2. Store a LuaEntity reference to the non-player character entity.
3. Used a script to teleport the car to another surface.

To replicate, load the attached save and run the following command:
/c game.print("Before teleport ...

LuaEntity::set_driver() and LuaEntity::set_passenger() both list the parameter with a "?" at the end, implying that the parameter is optional. However, calling either function with 0 parameters will cause a script error.

You must explicitly write "nil" in the argument list in order to use the ...

I agree. Even though the most common thing to do after installing a mod is load a save that does not already have the mod in it, you should always be given the options to sync. There should not be special treatment given to saves without *any* mods yet. Especially since Space Age DLC exist as mods ...

Potentially a duplicate of the very unintuitive behavior you called intentional here: viewtopic.php?p=673916

Edit: Apparently this is a different behavior altogether.

Suggestion to solve the original problem:
Check the last_user or the just built entity.
Check the cursor_stack of that player.
If it's not an underground pipe, don't do anything.
That way if they are holding a blueprint, it won't trigger.

1. It's impossible to delete forces. You can only merge them. You can choose to delete all the entities on the unwanted force before you merge them, or you can allow them to be reassigned.
2. Many mods make hidden forces to achieve certain things. The mod that lets you make overlapping independent ...

The force parameter of each entity is changed automatically by the game during the "game.merge_forces" function call. The entities continue to exist and the same LuaEntity references are still valid. You do not have to do anything, except any special logic that you need to run to make your mod work ...

All the entities in the "source" force should have their force changed to the "destination" force before the source force is deleted.

+1, but OP I think you put the wrong pictures in the first post? I see several versions of the "trash unrequested" inventory checkbox instead if the R/G circuit wire selector. And change the title to explain what "those" checkboxes are.

What do you mean by that ? We both had the problem.

The computer that shows the desync error isn't necessarily the one that is faulty. If your computer has a faulty component, then it will desync when connected to a non-faulty server. But also, if the faulty computer is the server, the non ...

Have you tried connecting your brother's computer to his switch? It's possible your computer has an issue.

An even unload is ensured for my examples in the second post. No matter how uneven the unloading is performed. Just one lane, complete block, slow, fast. All the chests will be empty within the same second. No circuit control required. That's because of the balancers at the output.


I tried ...

You can always add a bypass route instead of having the buffer directly in series between input and output.

You need to identify the reasons for the uneven unloading before you can fix it. Tertius's example solves one issue, which is that the inserters placing items farther from the exit will ...

For a better example of compound entity management, look at how Shortwave Fixed radios work, and how Cargo Ships oil rigs work.

Nevermind, I think this is not a bug. After some testing I figured that interrupts with the same name override each other as well. I changed name from "Dispatch" to "Dispatch - *W" in my case where * is number of wagons and started to work.


Oh right. Interrupt names are also overridden by what ...
