[1.7.2] How do you make a fluid that only does damage to specific mobs?

[kennybenny]

I am making a fluid (oil) and I want it to do damage to most of the non-hostile mobs in minecraft, how could I do this?

 

Here's my code:

 

 

package k3.moremetals.mod.block;

 

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import k3.moremetals.mod.MoreMetalsMod;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IIconRegister;

import net.minecraft.creativetab.CreativeTabs;

import net.minecraft.util.IIcon;

import net.minecraft.world.IBlockAccess;

import net.minecraft.world.World;

import net.minecraftforge.fluids.BlockFluidClassic;

import net.minecraftforge.fluids.Fluid;

 

public class BlockOil extends BlockFluidClassic {

 

     

public IIcon stillIcon;

public IIcon flowingIcon;

       

        public BlockOil(Fluid fluid, Material material) {

                super(fluid, material);

                setCreativeTab(MoreMetalsMod.moreMetalsTab);

                setDensity(1500);

        }

       

        @Override

        public IIcon getIcon(int side, int meta) {

                return (side == 0 || side == 1)? stillIcon : flowingIcon;

        }

     

 

        public void registerBlockIcons(IIconRegister register) {

            stillIcon = register.registerIcon(MoreMetalsMod.modid + ":oil_still");

            flowingIcon = register.registerIcon(MoreMetalsMod.modid + ":oil_flow");

    }

       

        @Override

        public boolean canDisplace(IBlockAccess world, int x, int y, int z) {

                if (world.getBlock(x,  y,  z).getMaterial().isLiquid()) return false;

                return super.canDisplace(world, x, y, z);

        }

       

        @Override

        public boolean displaceIfPossible(World world, int x, int y, int z) {

                if (world.getBlock(x,  y,  z).getMaterial().isLiquid()) return false;

                return super.displaceIfPossible(world, x, y, z);

        }

       

}

You might want to look how lava does this. Remeber lava is a fluid and not all entities/mobs are hurt by it. I never made a fluid, but I would start looking there. Hope it helps!

I can't find the code for lava, I searched for it and all that. I think that I need to make a custom material for my fluid too, how would I do that (preferably without editing minecraft code)?
