Hi, I'm trying to make boots that when worn as you are walking, it changes water to ice if you walk on the water.  Can someone help me with this?

I recommend checking out onArmorTickUpdate in the Item.class.  You can use it on your boots so that when they are equipped, you can check where the player is and see what block they might be standing on.

I've been using the onArmorTick method, however I'm having trouble finding out how to find and replace the right block.  So far I've got this.

 

 

@Override

public void onArmorTick(World world, EntityPlayer player, ItemStack armor) {

int x = (int) player.posX;

int y = (int) (player.posY - 0.5D);

int z = (int) player.posZ;

Block block = world.getBlock(x, y, z);

        if(armor.getItem() == ElementalArmor.iceBoots){

if(block == Blocks.water){

world.setBlock(x, y, z, Blocks.ice);

}

        }

}

 

 

Well, with the y, I recommend just doing y = ((int)player.posY)-1

That worked about the same.  I should probably specify.  It will replace the water block to the east but not to any other direction.

Maybe you can search several blocks around the player and changes the water block(s) to the ice.

 

like:

for(int i = -1; i <= 1; i++)

for(int j = -1; j <= 1; j++)

for(int k = -2; k <= -1; k++){

if(world.getBlock(posX-i, posY-k, posZ-j) is waterblock)

change the block to ice block.

}

That changed the water to ice all around me but only while I'm at least half way in the water.

Which is why you change it back to 0.5D <3

@Override

public void onArmorTick(World world, EntityPlayer player, ItemStack armor) {
   int x = (int) player.posX;
   int y = (int) (player.posY - 0.5D);
   int z = (int) player.posZ;

   if(armor.getItem() != ElementalArmor.iceBoots) return;

   for(int i = -1; i <= 1; i++)
     for(int j = -1; j <= 1; j++)
       for(int k = -2; k <= -1; k++){
           if(world.getBlock(x-i, y-k, z-j) == Blocks.water)
                world.setBlock(x-i, y-k, z-j, Blocks.ice);
      }
        
}

 

Did you try this?
