Pipes only connecting to my entity if the pipe is placed 1st

Posted: Mon Jul 24, 2017 10:59 pm

I am making a gas-powered boiler, which works with a compound entity (a special boiler type, and a hidden gas-input assembler underneath). It all works, except for the fact that the hidden assembler only connects to pipes if the pipe is placed first. I have no idea why this is. The assembler's recipe is set the moment it is created and placed in the world.

Relevant code:

Code: Select all

Re: Pipes only connecting to my entity if the pipe is placed 1st

For those who may be reading, I have a workaround, but it is fairly crappy: Destroy and replace my entity if a pipe is placed nearby, making an attempt to preserve properties like fluid contents and active recipe. This works...mostly, but is still messy.

It would be so much better if there was native support for fluids to be used as fuels.

Which we were promised would be a thing by 0.13 in a features list posted back in the 0.10 roadmap.

It was part of the fluid overhaul system, were the two key features were fluid wagons and fluids as fuels. Which was bumped to 0.14 in 0.11 roadmap, which would put it as a 0.15 feature as part of the fluid overhaul (we got fluid wagons) since 0.14 was basically 0.13 with better multiplayer and vehicle equipment grid support.

Therefore, we SHOULD be able to do it, but the devs broke their promise.
