[0.17.43] Weird corner pipe hitboxes

In this example, the character can successfully navigate between the underground pipe and the regular pipes in the first three examples, where there is no corner of pipe. Inconsistently, however, the character can not navigate round the corner of pipes in the last two examples. They can only make it to the corner from either end, but not leave. This is very weird that there would be enough room for the character to go through vertically or horizontally, but not both!

Although I didn't include examples in this save, this also happens when the straight pipes are replaced with underground pipes or vice versa---in particular, you cannot navigate around nested corners of pipes.

No mods are necessary to see this behaviour. Attached save and log.

Thanks for the report.

You could argue that not being able to walk between pipes in some scenarios is a bug but I can also argue that at no point have we ever said being able to walk between pipes was meant to even be a thing.

More so, it's one of those "it works this way, lets just keep it working that way".

I don't consider this worth the incredibly large risk of breaking everything else involved with pipes by changing pipe collision boxes.

You could also say that the corner piece’s outer edge doesn’t make an exact, sharp 90 degree corner and instead curves/rounds into it, thus cutting into the available walking space. Makes sense from that pov.

I think that moving between two parallel pipes is quite reasonable personally (in actuality, large pipelines are often above ground level so you can sometimes even go underneath!). I wanted to look into doing this with a mod, but is the enlarged hitbox for a corner pipe hardcoded? I can't find anything that looks like it might code for it in the game files.

Yes, though if you think about it, you could potentially put them too close together IRL, too, which is exactly what what you’re doing here. These pipes are almost a meter across. There’s maybe 20-40 cm max between the pipes at the widest points. You can just simply build the pipes with a meter/tile space between them and this would solve that.

Eh. That's been reported ages ago (can't find any of the though). Happens in all sorts of weird configurations, for example when you build pipes on a shoreline, or around steam engines. I personally "fixed" it by decreasing the size of the players collision box by 25% to a diameter of 0.3.

Would you mind sharing how to do it?

Thanks!

It's only one string in the data.lua:

Code: Select all

data.raw.character.character.collision_box = {{-0.15, -0.15}, {0.15, 0.15}}

Just make new mod, copy and change info.json from another mod, than add the file data.lua with the code above.

I just ran into the same problem, I don't remember having this problem in 1.16...

I would suggest a simple fix that shouldn't break anything: Instead of reducing pipes hitbox, why not reduce only underground pipes hitbox?

That *is* the risky change: reducing pipe hitboxes. Pipes are pipes and underground pipes

What's risky about it? Squeak Through does it as a matter-of-course.

Edit: Though I guess there's only really one lever for collision box with pipes and like 20+ configurations, so you can't change only one and not the others.
