[1.12.2] Get amount of fluidTank in GUI


Yruel

Recommended Posts

I have a tileEntity with two FluidTanks but if i want to show the amount of fluid in one tank in the GUI the amount is always null. I tried many different solution but no one worked. I get the capacity of the tank in the gui but not the liquid in it or the amount of liquid which is is the tank, can anybody help me out?
