[Help!] How to make a block spawn another block

[MINERGUY67880]

Hi, I am trying to make my stone crusher machine make my smoke gas when it is activated. I am trying to use this code:

//Smoke Spawning Method
    public void updateTick(World world, int x, int y, int z, Random rand) {
    	int CurrentY = y + 1;
    	TileEntity tileEntity = world.getBlockTileEntity(x, y, z);
    	if (tileEntity instanceof TileEntityStoneCrusher) {
            TileEntityStoneCrusher crusher = (TileEntityStoneCrusher) tileEntity;
    	if (crusher.active) {
    world.setBlock(x, CurrentY + 1, z, TechnicCraftCommon.SmokeGasBlock.blockID );
    
    }
    }
    }

 

But it doesn't work, what am I doing wrong?

Throw some debug in there and work out if its being called.

[MINERGUY67880]

i put in a system.out.println and it didnt write it in the console. It isn't getting called.

[skullywag]

so what have you got making it tick, tickrandomly?, tickscheduler?

Random question:

 

Why do you set currentY to the block above your block, then set the smoke to appear one block above that?

 

Second, is metadata 0 appropriate for that particular gas?

[MINERGUY67880]

Im not sure why I did the +1 for the CurrentY. Heres my new code:

//Smoke Spawning Method
    public void updateTick(World world, int x, int y, int z, Random rand) {
    	TileEntity tileEntity = world.getBlockTileEntity(x, y, z);
    	if (tileEntity instanceof TileEntityStoneCrusher) {
            TileEntityStoneCrusher crusher = (TileEntityStoneCrusher) tileEntity;
    	if (crusher.active) {
    world.setBlock(x, y + 1, z, TechnicCraftCommon.SmokeGasBlock.blockID );
    
    }
    }
    }

Try using the onUpdate() method.

Still doesn't work.

Where is this Update Ticker? Block? Tile Entity?

 

Also as I put above put some debug in there to be sure its even being called, you could be staring at this code and it not be the problem.

world.scheduleBlockUpdate(x, y, z, blockID, ticks_of_delay)?
