I ran into this recently when writing a mod. I accidentally set the speed of the car to some really high value -- which meant that the engine had to generate a full 25 chunks every single tick. The game effectively froze entirely, and I had to kill it. It might have been nice to get a more graceful ...

The rail segment visualisations appear to come from data/base/graphics/entity/rails/rail/rail-segment-visualisations-endings.png (and likely rail-segment-visualisations-middle.png as well). The sprite sheet uses 64x64. But each element only uses a portion of the space.

I tried changing a single ...

The Toggle entity control is great. However, it is missing one key feature: it needs a sound effect to confirm that it has taken effect. This could be as simple as adding utility/gui_click to it. Each of the operations that it simplifies (automatic/manual for trains and on/off for constant ...

Setting player.zoom should update the current remote view history item just like it would if the player changed the zoom with the mouse wheel.

If the zoom level is changed with the mouse wheel, the current zoom level is remembered when traveling backward and forward within the remote view history ...

Sometimes a mod would like to remove a button (or frame) that it previously added. This is trivially done by calling destroy() on the gui element. This will of course remove the element from the button flow or the frame flow.

However, the top frame and inner frame elements still exist. And if the ...

Alright; the first version has been released: Speed Governor. Give it a try, and let me know if it works!

LocomotivePrototype.reversing_power_modifier is not exposed via LuaEntityPrototype at runtime.

I would like to read this value at runtime to support arbitrary custom locomotives when calculating how much energy was actually consumed during a tick while a train is reversing manually.

A follow-up:

I'm making good progress on this. I'm very proud of the GUI I've developed to show the current vehicle speed limit.

I realized that I didn't support trains initially, but I really do need to. That support should be added tonight.

In terms of the keybindings, I've currently ...

I was already thinking about implementing mod like this recently. I want the ability to drive along a wall and pick up items faster. But the car moves too fast. I typically manage this by manually pumping the accelerator, but that is error prone. It would be great if I could set a lower top speed ...

I'm not entirely sure what you are trying to achieve here, but there is something you may be interested in:

mods are stored in a directory called "mods" inside your game folder (right next to saves). The executable has an option to specify a different directory. So, without having different saves ...

When processing an on_selected_entity_changed event, I would like to know if the rail planner is active (as distinguished from a rail item in the cursor stack). In my research, I don't think this is possible, but perhaps I missed something?

If this is not possible, I would like to request an API ...

I would be particularly interested in this feature.

The holmium-solution recipe requires 2 holmium-ore, 1 stone, and 10 water. By default, holmium-ore is not used for anything else. So, if I have higher quality holmium-ore (whether intentionally or not), the only way to consume it is to create ...
