Galacticraft frozen fuel problem

[Aragrohl]

This happened when using the 78 Beta galacticraft build and the 7.99.1 alpha buildcraft build, here's the log.

looks like the BC fluidrenderer is choking on the galacticraft fuel, might be an issue on their side but the code should probably be made more robust so it doesn't completely crash

[Aragrohl]

Ok I'll post on their github then.

looking more at it BC is purposely crashing atm when it fails to map a texture, i'm not exactly sure if it's a BC issue or that something is wrong with that fluid

@AlexIIL are you sure this is the route we want to take in this case? wouldn't it be better to use the missing texture texture instead so atleast the game can load? that texture should be indication enough that something needs fixing without breaking things on launch

[AlexIIL]

Its alpha. Its crashing so that I can pick up where code doesn't work rather than just logging an error as then they wouldn't get reported.

thanks guys, just confirming this is not a Galacticraft issue :) (it was reported to us as well)

@AlexIIL anything we can do to help on Galacticraft's side, please comment on micdoodle8/Galacticraft#2660 - I can also give you my Skype privately so you can contact me directly if you need it

@radfast I haven’t looked into it yet but it is almost certainly a BC logic bug. I'll post more details when I've looked into it though.

@AlexIIL I think it's likely that what has happened here is that Galacticraft also registers a fluid with the same name fuel and as you know, the Forge fluid system picks one of the two mods registering the fluid as the "default" fluid for that name.

I'm actually not sure how Forge picks between the mods, but I guess in this case it picked us first ... ;)

If there's some parameter I can change when Buildcraft is present, to tell it to give your fluid priority, I don't mind doing that. Obviously we want full compatibility between our two mods. Galacticraft is built to be resilient if another mod registered fuel first. Especially with Buildcraft we have always given priority to Buildcraft's oil and fuel in pre 1.11 versions.

nonono, its a bug in buildcraft's texture duplication + expansion code. Basically, for every fluid's still sprite it creates a new sprite called "buildcraftlib:fluid_" + srcLocation.toString().replace(':', '_') + "_convert_frozen", and if it fails to stitch this new sprite to the map (as no other mod should use the buildcraftlib namespace) then it crashes. I guess what's happening here is they you have two fluids that both use the same sprite (and so I'll tweak the impl to not recalculate a new sprite if its already done it)

frozen fluids, sounds like fun.

We have a Liquid Nitrogen Canister item. If the player activates the item on a water block, it turns it into Ice. Maybe I can extend this to freeze all your fluids too :)

[AlexIIL]

Its used for making the flow effect in fluid pipes - it doesn't look quite right if we use the still image directly, so we double the size of the first frame.

I'll leave you to it, you're welcome to get in touch if any future compatibility issues arise.
