[1.8]Set Block State

[KingOfMiners]

I'm making a cherry leaf block and i want it so it has a small chance to change into a leaf that has cherries on it and i would be able to do it but i don't know how to use setBlockState[move]*Fail*[/move] but i need help

if(this.hasCharry == false && rand.nextInt(500) < 1){
        	
        	int i = pos.getX();
        	int j = pos.getY();
        	int k = pos.getZ();
        	BlockPos bpos = new BlockPos(i, j, k);
        	
        	worldIn.setBlockState(bpos, state);
        	
        }

oh and yes i googled it.

Will It Work Now:

public void updateTick(World world, BlockPos pos, IBlockState state, Random rand)
    {
        super.updateTick(world, pos, state, rand);

        if(this.hasCharry == false && rand.nextInt(500) < 1){
        	
        	int i = pos.getX();
        	int j = pos.getY();
        	int k = pos.getZ();
        	BlockPos bpos = new BlockPos(i, j, k);
        	
        	world.setBlockState(bpos, MoreOresModBlocks.charry_leaves_full.getDefaultState(), 0);
        	
        }
        
    }

Will It Work Now:

Why ask when you can simply try it in your development environment? Then you can find out immediately whether it works or not.

 

Btw, that last argument to setBlockState is a bit flag that tells Minecraft whether or not to update the client side / notify neighboring blocks / other things, and you almost always want it set to either 2 (notify client) or 3 (notify client AND notify neighbors, IIRC).
