Bucket for Custom Fluid Support [SOLVED]

[calebty1]

Hi all, I have recently started becoming a minecraft modder, and I have the basics down. Adding items and all that stuff. I recently moved into adding custom fluids which I was able to achieve. I am stuck on adding a bucket that can pick up and place my fluid. I have followed the tutorial provided by MinecraftForge, but it still doesn't work. I also went as far as referencing from the BuildCraft code. I'm pretty sure I am overlooking something small, but can't figure out what it is. I have already debugged enough NPEs to know where to start, but I am not sure what is causing this one. I have taken a look at the FluidRegistry and Fluid stuff with Minecraft Forge.

Like I said I know exactly where it's coming from, but I don't quite know why it's returning null. Something with this line perhaps?:

        if (!fluidIDs.containsKey(fluidName))
        {
            return null;
        }

Anyways, I will leave it up to you to try and figure out. Thanks .

[sequituri]

It's a matter of case in FLuid names. They are internally converted to lower case. That cannot be found by GetFluidStack except in lower case. So, you get a null for the fuild.

 

There should be some documentation about that, as it is a very common crash.

[calebty1]

Sure enough that fixed it. Thanks!
