how exactly do I use it? here's what I have so far. but it doesn't work. By this I mean, it doesn't change anything at all from what I can tell. This is only the relevant part of the class file that I'm posting. so not the whole file.

 

public ArmorLyoko(int i, EnumArmorMaterial enumarmormaterial, int j, int k, String str)
        {
                super(i, enumarmormaterial, j, k);
                this.setCreativeTab(CodeLyoko.LyokoTabs);
                this.armorType = str;
                this.setContainerItem(this);
        }
        
        private ItemInWorldManager iiwm;
        private static double prevReachDistance = 5;
        private static double currReachDistance = 10;

       //non-relevant code here

public void onArmorTickUpdate(World world, EntityPlayer player, ItemStack stack)
        {
        	iiwm = new ItemInWorldManager(world);

        //more non-relevant code here

        else if (helmet.getItem() == CodeLyoko.YumiHelmet && chest.getItem() == CodeLyoko.YumiChest
    					&& legs.getItem() == CodeLyoko.YumiLegs && boots.getItem() == CodeLyoko.YumiBoots)
    			{
    				if(currReachDistance != iiwm.getBlockReachDistance())
    				{
    					iiwm.setBlockReachDistance(10);
    				}

        //more non-relevant code here

        else if (player.getCurrentItemOrArmor(4) == null || player.getCurrentItemOrArmor(3) == null
    				|| player.getCurrentItemOrArmor(2) == null || player.getCurrentItemOrArmor(1) == null)
		{
			if(currReachDistance != prevReachDistance)
			{
				iiwm.setBlockReachDistance(prevReachDistance);
			}
		}
     }

 

since I use multiple armor pieces for it to work, it's ok to use onArmorTickUpdate

You probably won't get around make a TickHandler here. Because: if you set the reach distance in onArmorTickUpdate and then the player removes the armor, it has no chance to set the reach distance back. Here is how to obtain the ItemInWorldManager:

if (player instanceof EntityPlayerMP) {

    ItemInWorldManager iiwm = ((EntityPlayerMP)player).theItemInWorldManager;

    // set reach distance

}

that didn't work. here's my code

https://github.com/code-lyoko-modding/CodeLyokoMod/blob/master/matt/lyoko/items/ArmorLyoko.java

you don't understand how the armor works. you need ALL pieces equipped to get the specified effect. So putting it in onArmorTickUpdate works. and I purposefully made it use one class.

would that get rid of the problem?

I mean it doesn't change the player's range for hitting blocks.

no. i guess i could try.
