i have created this but the methods are out of date and i don't know how to update them. help appreciated

package ashtonsmod.common;
import net.minecraft.block.Block;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;


public class WoodStaff extends Item {
public WoodStaff(int par1) {
super(par1);
}

public boolean onItemUse(ItemStack is, EntityPlayer player, World w, int x, int y, int z, int l, float f, float f1, float f3){
if(w.getBlockId(x, y, z) == Block.planks.blockID){
w.setBlockMetadataWithNotify(x, y, z, w.getBlockMetadata(x, y, z)+1);

if(w.getBlockMetadata(x, y, z) == 4){
w.setBlockMetadata(x, y, z, 0);
}
else if(w.getBlockId(x, y, z) == Block.wood.blockID){
w.setBlockMetadataWithNotify(x, y, z, w.getBlockMetadata(x, y, z)+1);

if(w.getBlockMetadata(x, y, z) == 4){
w.setBlockMetadata(x, y, z, 0);
}
}else if(w.getBlockId(x, y, z) == Block.stairsWoodSpruce.blockID){
w.setBlockWithNotify(x, y, z, Block.stairsWoodBirch.blockID);
}else if(w.getBlockId(x, y, z) == Block.stairsWoodBirch.blockID){
w.setBlockWithNotify(x, y, z, Block.stairsWoodJungle.blockID); 
}else if(w.getBlockId(x, y, z) == Block.stairsWoodJungle.blockID){
w.setBlockWithNotify(x, y, z, Block.stairCompactPlanks.blockID); 
}else if(w.getBlockId(x, y, z) == Block.stairCompactPlanks.blockID){
w.setBlockWithNotify(x, y, z, Block.stairsWoodSpruce.blockID); 


return false;
		}
	}
}
}

 

the errors are under all of the .setBlockWithNotify and the .setBlockMetadataWithNotify

i know they updated these methods

someone must have updated a mod with similar problems?

they're backin 1.5.1. update to 1.5.1

or explain what the problem is, more specifcly

the firs method is undefinable and the second is unaccpetable

setBlockMetadataWithNotify(x, y, z, BlockID, metaData, notify, 2)

 

setBlockWithNotify(see above)

by using your brain ... T.T
