Checking Neighbour Block

Recommended Posts

Hi, I am trying to make a block that explodes when in contact with water (lithium).

 

I have tried to make this code, but it only works if the neighbour block is a liquid, and THEN it is replaced. I want it to explode as soon as water is placed next to or flows to the block. (water_still and water_flow)

 

Here is my current code (the spoiler button decided not to work, sorry):

 

 

public MMCLithiumBlock(int par1, Material par2Material) {

super(par1, par2Material);

}

 

public void onNeighborBlockChange(World world, int i, int j, int k, int l){

 

if(l > 0 && Block.blocksList[l].isBlockReplaceable(world, i, j, k) == true)

        {

world.createExplosion((Entity)null, i, j, k, 1, true);

}

}

By the way, "Block.blocksList[l].isBlockReplaceable(world, i, j, k)" won't just explode on water.

 

It'll explode on a whole host of other things too.  Like snow, lava, tall grass, and many mod blocks such as mod added liquids and gasses.  I even have a mod that creates a solid block you can walk on, but has no outline, no texture, and can be replaced by other blocks.

 

Dimensional Doors uses a isReplacable block for the volume-material of its pocket dimensions.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Use what both of these guys said. Check if the block id is water, not if it's replaceable. Also use onBlockAdded so that way it doesn't have to wait for the block next to it to change once it's placed.

If you really want help, give that modder a thank you.

 

Modders LOVE thank yous.
