Store potion in blockdata


BlockyPenguin

Recommended Posts

Hi, I'm fairly new to modding, and I'd like to know if it's possible to store a potion's effect (e.g. slowness, invisibility, strength, etc) inside of some blockdata. If not, how else could I do this?

I'm probably more excited than I should be for something so realistically minor...

What are you trying to do, from a players perspective?

So, I'm looking to make a block that, when right-clicked with a potion, will store that potion's data (effect and length) in some blockdata, then when the player right clicks again with an empty hand, it gives them the correct effect for the correct amount of time. If that sounds too op, don't worry, it only has three uses :)

Edit: Or maybe I could use a String if that's possible?

Your block will need a TileEntity. Then you can store an EffectInstance in that tile entity. You can use EffectInstance#write(CompoundNBT) to store this effect in NBT.

Cool, thx. :)

Okay, so I've added this code to my block's constructor:
 

CompoundNBT nbt = new CompoundNBT();
EffectInstance potion = new EffectInstance(Effects.LUCK, 6000);
potion.write(nbt);

 

but if I run "/data get block <x> <y> <z>" ingame, it doesn't give me any info on the potion, just the x, y, z and id, so I'm guessing it isn't writing properly. Nothing seems to be amiss in the logs. Please forgive me if I'm missing something important here, this is my first time working with TileEntities.

I created an EffectInstance and passed some CompoundNBT in the .write method.
