[ Solved ]An item fuel that uses energy stored on equipment grid to power vehicles

Yep it's buffering

Energy: 1.0MJ/1.0MJ

Okay, let's try some debugging.

Inside the "onBuilt", just before the "end", insert:

Code: Select all

game.print("Registered vehicle "..entity.unit_number)

Likewise inside "onMined", add:

Code: Select all

game.print("Unregistered vehicle "..entity.unit_number)

This should cause a chat message to appear when you place or remove vehicles. If this works, then the registration part is working fine and the problem lies in the onTick part, so this is a great way to divide up the debugging problem!

[N0TZ3R0]

Sir, it's unregistering the vehicles ( I can c their IDs ) but not registering, I think it's something with onBuilt.

[N0TZ3R0]

If I remove this line do to a test:

if not (entity and entity.valid and isVehicle(entity)) then return end ( it's in control.lua )

And place a vehicle, I get an error:

O mod ZElectricEngine (0.0.1) causou um erro não recuperável.
Por favor, reporte este erro ao autor do mod.

Error while running event ZElectricEngine::on_built_entity (ID 6)

stack traceback:

Aha, I see.

Code: Select all

  local entity = event.entity or event.built_entity

This line is wrong. It should be:

Code: Select all

  local entity = event.entity or event.created_entity

Whoops!

Some good News, It's working perfectly fine as I wanted, I will remove the debugging and change somethings then release it, bro thanks a lot for the help, I'll put your name there haha

[N0TZ3R0]

Only one thing I notice is that it drains power while the vehicle isn't used, Is there a way to add a check if player is inside then debit the energy ?

[PFQNiet]

It's supposed to drain power to fill up the fuel bar. Once the fuel bar is full, "missing" should be 0 so it shouldn't be draining any power.

Might be worth adding this debug line after the "local missing = CAPACITY - ..." line:

Code: Select all

game.print("Vehicle "..car.unit_number.." is missing "..missing.." energy")

That number should start out at a million (1MJ) and gradually drop to 0 as the generator fills the fuel bar. Can you test that?

[N0TZ3R0]

Oh I c, it was my fault sorry, I checked it again and I changed a wrong value, so now it's fully working.

I feel like I've just accidentally written an entire mod without having Factorio available XD

[N0TZ3R0]

Yep sir haha, I'll give u credit when I post it.
