hello guys,

 

i got a small problem,

 

i cannot find a small solution for "setBlock" ...

 

and for

 

      int x = par1MovingObjectPosition.blockX;

      int y = par1MovingObjectPosition.blockY;

      int z = par1MovingObjectPosition.blockZ;

 

also not ... x.x

That's because setBlock(x, y, z, block) is now setBlockState(BlockPos, IBlockState)

Individual x/y/z block coordinates have been replaced by

BlockPos

objects.

Block

and metadata arguments have been replaced by

IBlockState

arguments.

 

Use

World#setBlockState

to set a block in the world. Use

Block#getDefaultState

to get the default

IBlockState

of a

Block

and then chain

IBlockState#withProperty

calls to get an

IBlockState

with each

IProperty

set to the appropriate value.

 

Use

MovingObjectPosition#getBlockPos

to get the

BlockPos

that was hit by the raytrace.

 

Forge's documentation has an introduction to block states here.

thank you both, i got it!
