kwpugh Posted July 24, 2019 Share Posted July 24, 2019 (edited) Hi, I'm looking for some guidance on how to effectively interate through the player inventory, test for a condition, and take an action. The following code is something I am attempting to migrate from 1.12.2, but having little luck. package com.kwpugh.gobber2.util; import com.kwpugh.gobber2.Gobber2; import com.kwpugh.gobber2.lists.ItemList; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.inventory.EquipmentSlotType; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraftforge.eventbus.api.EventPriority; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod.EventBusSubscriber; import net.minecraftforge.fml.common.gameevent.TickEvent; import net.minecraftforge.items.CapabilityItemHandler; import net.minecraftforge.items.IItemHandler; @EventBusSubscriber(modid = Gobber2.modid, bus = EventBusSubscriber.Bus.FORGE ) public class RepairTickHandler { int DELAY; Item repairGring; int time; public RepairTickHandler(Item item, int delay) { repairGring = item; DELAY = delay; time = DELAY; } @SubscribeEvent(receiveCanceled = true, priority= EventPriority.HIGHEST) public void onPlayerTick(TickEvent.PlayerTickEvent event) { PlayerEntity player = (PlayerEntity) event.player; IItemHandler inv = (IItemHandler) player.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, null); for (int i = 0; i < inv.getSlots(); i++) { ItemStack target = inv.getStackInSlot(i); if (target.getItem() == ItemList.gobber2_ring_repair) { time--; if (time <= 0) { time = DELAY; repair(player); } } } } private void repair(PlayerEntity player) { IItemHandler inv = (IItemHandler) player.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, null); for (int i = 0; i < ((IItemHandler) inv).getSlots(); i++) { ItemStack target = inv.getStackInSlot(i); if (!target.isEmpty() && target.getItem().isRepairable(target)) { if (!(player.isSwingInProgress && target == player.getItemStackFromSlot(EquipmentSlotType.MAINHAND))) { if (target.isDamaged()) { target.setDamage(target.getDamage() - 1); return; } } } } } } It is not working as expected and I am not sure why. Any guidance would be helpful. Regards, Thank you. Edited July 24, 2019 by kwpugh Quote Link to comment Share on other sites More sharing options...

Define not working as expected have you tried outputting values to the console? Specifically to determine where the execution stops and the values of the variables to determine why it stopped.

kwpugh Posted July 24, 2019 Author Share Posted July 24, 2019 I had put System.out.println statements in the onPlayerTick and repair methods and nothing prints in the log, telling me that my code is never hit. Quote Link to comment Share on other sites More sharing options...

But that kinda brings back an old issue we had pre 1.10(I think). Where you had to know which bus you needed to use.

kwpugh Posted July 24, 2019 Author Share Posted July 24, 2019 Ok, I see. I mis-read. The doc explains BOTH static and non-static methods and indicates that "An event handler may also be static", I didn't understand that it is required. I got it working, thank you.

Read the documentation about events. Ok, you confused me. You said the event handler methods must be static before. Quote Link to comment Share on other sites More sharing options...
Draco18s Posted July 24, 2019 Share Posted July 24, 2019 1 minute ago, kwpugh said: Ok, you confused me. You said the event handler methods must be static before. Option A: - The event class is registered statically, therefor the methods must be static Option B: - The event class is registered as an instance, therefor the methods must not be static Notice how the first part and the second part match? Notice how both options are possible? Event handlers are not required to be static, but you have to match.
