FWIW, this is not specific to vscode. I can get the same behavior in IntelliJ as well. This is a video from an intellij session where I actually crashed the game (no dap log captured here, need to figure out how the intellij dap adapter does that).

As this is not from vscode, I don't expect this to ...

When debugging code, sometimes execution jumps forward while adding or removing breakpoints. The behavior is not deterministic, I seen it most with breakpoints in early runtime stage (on_init, on_load, on_configuration_changed).

attached is a video, game log and dap log from a session where this ...

Amazing, thank you!

Now, combinators! We need combinators. And (I guess it is controversial because you live in the home town of prusa), any chance to get colored .3mf files? I can see people starting to recolor those but with real multicolor printing starting to become real, it would be great to ...

Thanks for pointing this out; as this is per-player it might work for me (need to test it).

(this is very loosely related to the "Allow placing GUI elements relative to the "Surface List" GUI" threads)

I have a mod where clicking on an entity may bring you to a remote view of a specific surface. I only want to show that surface and not allow navigating away. But I can't see a way to turn ...

(I have done some research and looked at the various threads over the years about the various controllers inventory but have not found a good answer)

Scenario: I have an entity that, when clicked, opens a different surface to allow building. Similar to what Factorissimo does. That gives me three ...

It took me a bit to understand how this jumped to locale. If I understand you correctly, this is because there can be "hidden" entities of a specific type and if they get built, you would need the locale to display the "technology researched" message, right?

Anyway, thanks for explaining; the ...

I am playing around with a mod that moves a player temporarily to a different surface in god mode. In that situation, I want the player only to be able to craft a few specific items, not everything that they have researched.

I was looking into ways to temporarily restrict which items can be ...

currently, a technology can be unlocked by building a specific entity. This leads to problems if e.g. the unlock is by building a roboport but some mod have changed the available roboport types (and removed the default game roboport).

It should be possible to unlock a technology by building ...

- Place the attached "Warehousing_1.1.1.zip" in your mods folder.
- Load the attached "hidden test" map. This should contain only the base game, the Warehousing mod and EditorExtensions

- Open the tech tree and look for Warehousing. There should be the base Warehousing researched and two logistics ...

- clone https://github.com/hgschmie/factorio-miniloader-redux.git into "miniloader-redux" in your mod folder. Checkout the 2.2.1 tag
- open the mod code in vscode.
- put a breakpoint on line 178 in scripts/event-setup.lua

- create a new game under the ...

Tell me what you need and I can provide it. I can do a full screen video if needed. It is one of two issues I have with FMTK right now.

The log is from the session where I took the screenshots. If you say it does not match, maybe that is the problem.

The portal is just a list of releases. It shows the latest release in the changelog bit you can release in any order. I do it all the time. E.g. https://mods.factorio.com/mod/electric- ... /downloads

FMTK 2.1.9

Stepping (using F7) through a mod. After receiving a `on_pre_player_mined_item` event, the debugger stops on this breakpoint:

This code lives in "scripts/controller.lua", lines 233-241:

Pressing F7 should ...

It used to be possible to modify the values of variables (locals, globals etc.) in the debugger by right-clicking in the Variables section in vscode. Using FMTK 2.1.9 and Factorio 2.1.17 however, it looks like this:

It is still possible to do so in the Debug ...

Probably should be a modding request (add an entity_type field).

I can unlock a technology by requiring the user to build a specific entity, but I can not do so on a specific entity type. This may lead to soft-locks if e.g. a trigger depends on "roboport" but some mod removed roboport and replaced them with "foo-roboport". It would be nice if BuildEntityFilter ...

Consider this technology prototype:


{
type = "technology",
name = "secret-gate",
hidden = true,
research_trigger = {
type = "build-entity",
entity = "roboport"
}
}


This works fine and the technology is not visible in the tech tree (so I can have other technology depend on it which in ...

Did this fix make it into 2.1.17? There was no mentioning of it in the release notes.

First thank you for adding this to 2.1.15! For the first time, I am able to draw the connectors for my miniloaders correctly by moving the connectors to the right layer!

However, it seems that the shadows don't move with them.
