The title says all. I tried to convert a mod from 1.7.10 to 1.10.2 and I'm stuck with this error: "The method getBlock(int, int, int) is undefined for the type IBlockAccess" And I have another problem with the getLightValue: "The method getLightValue(IBlockState, IBlockAccess, BlockPos) in the type Block is not applicable for the arguments (IBlockAccess, int, int, int)"

Hope in advance!

(Almost) every method taking 3 coordinate integers take a BlockPos argument now.

thanks!

but how do I take a BlackPos?

Edited by DoubleSix6

You either create a new instance of BlockPos, or use one you already get from method arguments. In this case, you have to create a new instance.

Just create a new BlockPos(x, y, z)

And I don't understand this. Can anyone send me the piece of code withthe blackpos? Because I am new to this

Do you know Java? Do you know how to create a new instance of an Object? You should learn at least learn the Java basics before trying to mod.
