I've been searching and searching but can't seem to find any way to give armor/tools an ability (breathing underwater, setting mobs on fire with a sword, etc.) I only found one tutorial, and the code it shows doesn't want to work...

 

 

public void OnTick(float f, Minecraft Minecraft)
    {
    ItemStack boots = Minecraft.thePlayer.inventory.armorInventory[0];
    ItemStack legs = Minecraft.thePlayer.inventory.armorInventory[1];
    ItemStack chest = Minecraft.thePlayer.inventory.armorInventory[2];
    ItemStack helm = Minecraft.thePlayer.inventory.armorInventory[3];
    if(helm != null && helm.itemID == helmetCopper.shiftedIndex && 
       boots != null && boots.itemID == bootsCopper.shiftedIndex &&
       chest != null && chest.itemID == plateCopper.shiftedIndex && 
       legs != null && legs.itemID == legsCopper.shiftedIndex)
    {
        Minecraft.thePlayer.fallDistance = 0.0F;
        Minecraft.thePlayer.isImmuneToFire = true;
            }
    }

 

 

Is there any thing wrong with this code? And if so could you please point it out?

I also have another question... Can I use the same code above to give items an ability?

try looking at ArmorProperties? thats just a guess but it could be worth a look

I am not sure either, but you might need a tick event and test for what you need each tick...

Tick event? Like ModLoader.setInGameHook?

World tick.  Hacky, but I am not sure of a better way off-hand.

Would ISpeacilArmor be better? Been also trying to figure that out as well... but only errors so far...
