Prototype of all stuffs related to train has rail_category field, what are they used for?

Is there a way to make a custom entity pop up its own GUI or open up other entity GUI? Like when I click it, it will open its neighbour's GUI.

Well, I want to make something entirely different gameplay wise, so making oil barrels have fuel value doesn't really seems all that different from vanilla.

I'm thinking of making invisible fluid wagon or storage tank as a proxy for the locomotives, then update remaining energy on the locos according to how much liquid left in the tank. Liquid wagon has better refuelling animation but the game doesn't allow me to place them overlapping with the loco no ...

Mod used :
Bugged Mod in my attachment

How to recreate :
place a locomotive on rail, then place another train part overlapping the locomotive, the game just crashed afterwards.

Are pumps hard coded to execute that animation only for fluid-wagon entity type or is it possible to use it for example a storage tank with opening on top?

LuaSurface::createEntity

orientation :: float : only for car, tank, locomotive, and wagons.

I want to create fluid wagon directly on top (overlapping) of locomotive every time I place locomotive. So far it seems I always end up making collision box and rendering problem.

How if I want to fill up vehicle energy with a type of fuel? Like electric train but uses rocket fuel acceleration bonus.

Where do I tweak vehicle acceleration variable for each fuel?

Is it possible for making locomotive able to hold liquid? I'm trying to make locomotive that works by consuming oil.

Factorio of course, what do you mean? I plan on tweak some biter behaviour.

Is there any development tools to aid modding, so that it allows for easy debugging?

Hello, how do I set up LDT (Lua Development Tools) to aid in modding. I can't find how to open factorio mod so that they show dependency between files like it did with java eclipse. Newbie modder here.

Seems like half the reply don't understand the problem, It's not when you want to use light oil/gas that is the problem. It is when you don't want to use them. And I stated earlier that it is unlikely scenario but doesn't mean it is not a problem.

The Original Problem : At some point of the game we might be needing lots of heavy oil but none of the other oil. The other oils will pile up no matter how much storage you dedicate and the best we can do is convert it to other product and store them. But then, we need to keep making storage for th...

Now that steam engine, steam turbine only consume steam, how do we burn excess oil byproduct? At some point of the game, I may need to produce large amount of lubricant but nothing else. If that happen, I need to constantly create new space for light oil and gas for it to work, but then at some poin...

I never see this idea before, awesome idea though.

Bots should be fire immune, it is very annoying if flamethrower turret put some flame puddle on a building and bots try to repair them at the same time. They will repair each other even so wasting even more repair pack. It's not even adding more difficulty to the game, it is just annoying to see you...
