[1.8.9][Loot] Changing default values of Minecraft entities, blocks or items

[Major Squirrel]

Good evening,

 

This question has surely be asked but I couldn't find an available answer for 1.8.9 with the search engine.

 

Is it possible to change the loot values/probabilities of Minecraft basic entities, and blocks such as BlockBushes ? Also, can I easily change the saturation of existing food ?

 

I suppose this is possible for BlockCrop/BlockBush and ItemFood, using substitution aliases, but I can't see any way for existing entities in Minecraft.

There is no way to try the substitution aliases for blocks and item ?

Unfortunately, that's a little beyond my current experience. I'm sorry.

You should be able to register substitution aliases for blocks and items (in fact those are the only things you can register substitution aliases for), but I haven't managed to get it working myself (see this thread).

 

You should always try to use events or hooks before you resort to drastic measures like replacing vanilla classes or modifying them with ASM. If there's no hook or event for your use case, consider suggesting one in the Suggestions section or on GitHub.

 

HarvestDropsEvent

lets you change drops from blocks.

LivingDropsEvent

lets you change drops from living entities (including players).

 

There's no direct way to modify the saturation value of existing food without resorting to some hacky reflection that makes the fields in

ItemFood

non-final, but you can subscribe to

PlayerUseItemEvent.Finish

and modify the player's food values through their

FoodStats

object if they used a particular food item.

Yeah I paid attention to your thread few days ago, in fact I was wondering if this was fixed in next builds or not. However, the thing that bothers me with events or hooks is that I have to use them as I implement new types of blocks or items, instead of coding them in their own class and be quiet.

At the moment I'm facing a problem : I would like to add a slow effect (not the enchant) to the player when wearing basic Minecraft armors. There is a specific value for each piece of armor, made of each ItemArmor.ArmorMaterial.

 

I suppose I have two possibilities : the first one would be to re-create the existing armors, adding my own onArmorTick event and registering the Items as a substitution, but it seems that it doesn't work very well (cf. Choonster post above). The second one would be to catch a specific TickEvent for my uses and checking each piece of armor the player is wearing, but it is called every tick for players and not every tick for pieces being worn.

 

I would implement this for a private server, and I can't really imagine how fast/slow it would be.

[Major Squirrel]

Using PlayerTickEvent for this should be fine.

 

Thank you diesieben07, I was wondering if I had to check the side of the event (Side.CLIENT or Side.SERVER) since it is a calculation assigned to the player ? I don't understand in which way I should handle sides in events...

Neither.  Use

World#isRemote

, specifically,

!isRemote

[Major Squirrel]

Is accessing to the player worldObj okay ?

 

    @SubscribeEvent
    public void                 onArmorWorn(TickEvent.PlayerTickEvent event) {
        Double                  result = 0.0D;
        Item                    itemArmor;
        AttributeModifier       armorSlowModifier;
        IAttributeInstance      attributeInstance;

        if (!event.player.worldObj.isRemote && event.phase == TickEvent.Phase.START) {
            for (int index = 0; index < 4; ++index) {
                if (event.player.getCurrentArmor(index) != null) {
                    itemArmor = event.player.getCurrentArmor(index).getItem();
                    result += ItemArmorHelper.getSlowValue(itemArmor);
                }
            }
            result = (1.0D / (1.0D + (result / 1.5D) / 2.0D));
            armorSlowModifier = new AttributeModifier(heavinessModifierMalus, "Armor heaviness malus", result - 1, 2).setSaved(false);
            attributeInstance = event.player.getEntityAttribute(SharedMonsterAttributes.movementSpeed);
            if (attributeInstance.getModifier(heavinessModifierMalus) != null)
                attributeInstance.removeModifier(armorSlowModifier);
            attributeInstance.applyModifier(armorSlowModifier);
        }
    }
