The one you suggested [...] doesn't actually eliminate self intersection


The suggested penalty eliminates the problem of a train pathing into itself while in a roundabout, as shown in the first screenshot. For clarity let me explain how it works in detail.

In that situation, the train computes ...

Could you explain why the cost adjustment I suggested won't work?

Feature request: 133322.

TL;DR

Currently, a train longer than the circumference of a roundabout can collide with itself. Provide an option to prevent that.


What?

Currently, if a long train repaths at just the right moment while in a roundabout, it can choose a new path that will collide with itself. I would like an ...

Since my https://forums.factorio.com/133314 was marked as a duplicate of this issue (which I don't dispute), let me summarize here the essence of what I said there:

This is a bug. A train should never cross a red signal.
The existing replies here (77759) do not adequately justify the current ...

Regarding https://forums.factorio.com/77759 , yes I think that is basically the same issue. Regarding that report, boskid says "Not a bug", but goes on to discuss primarily path cost issues, which I think is secondary to safety.

They also say:

there is exception for signaling that allows train to ...

If a train approaches a red signal controlling access to a block that that train is already in, the train will ignore the red signal and hence crash into itself. This is a bug; the most fundamental rail safety rule is a train should never cross a red signal.

When using my RoboTank mod , I can deploy a squad of tanks remotely using a blueprint, but picking them up again has to be done using the right-click-in-map-view mining trick (which I only learned about from this forum post).

That said, it is sometimes useful that the vanilla tank and car ...

TL;DR
Allow mods to access the tank's trash inventory by providing a proper inventory defines constant.

What?
Currently, there is no symbolic constant in defines.inventory for the tank's trash inventory to use with get_inventory . There is only car_trunk and car_ammo.

Experimentally, I found ...

I ran into this problem myself and found a workaround suitable for some situations:

Wire all of the buffer chests together to get their combined contents.
Put that through an arithmetic combinator set to multiply the "each" (asterisk, "*") signal by -1, and output "each" as well. That gives the ...

When there are a lot of logistic bots in a network, they tend to queue in large numbers on a small number of overloaded roboports even when there are unused roboports nearby.

Example screenshot:

In this screenshot, the network has 2400 bots, with none free. It does not matter ...

I'm working on a mod that adds a form of deconstruction planner that analyzes a portion of the factory to find unused entities and marks them for deconstruction. It would be very convenient if the user could undo this action, but the API offers no way to accomplish that.

Furthermore, I think ...

Thanks! I was able to find the right place to do that, so the issue for Smart Cannon Shells is resolved as of 0.2.1 of that mod.

In the specific case of Smart Cannon Shells, they already have projectile.force_condition = "not-friend" set, but that does not affect explosive splash damage.

I created modded versions of the stock cannon shells that do not do
friendly fire damage:

They work by setting force_condition="not-friend" on the projectile.

I'm glad you like the mod! I noticed this because of your YouTube comment (I don't know how to monitor Factorio forums). I just posted version 0.3.1 that should solve the problem. (I would reply on YouTube too but I get "failed to post comment" error now...)
