Gess1t

not as much java as i would need apparently for minecraft modding, know some C# for unity, and basics in python for school

updated the github https://github.com/Mrcubix/Full-Inventory-Checker, with my actual code: package Gess.mod; import Gess.mod.proxy.iProxy; import net.minecraft.client.Minecraft; import net.minecraft.entity.player.EntityPlayer;

for the first part, make it an if statement with a boolean i set to false when activated so it only run once, then for the second part, i apparently have to set it outside of if statement, but where, and how? it's not return ItemStack.EMPTY; cause it error and ask to edit void for ItemStack instead, whihch isn't what i want EDIT: so apparently i have to use NonNullList<ItemStack> previous = NonNullList.withSize(player.inventory.getSizeInventory(), ItemStack.EMPTY); as someone suggested me, but just using this line won"t work

in theory, i should just have to do that : this.previous = new ItemStack[player.inventory.getSizeInventory()]; but it doesn't work package Gess.mod; import Gess.mod.proxy.iProxy; import net.minecraft.client.Minecraft; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import net.minecraft.util.text.TextComponentString; import net.minecraftforge.common.config.Configuration; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.fml.common.Mod.EventBusSubscriber; import net.minecraftforge.fml.common.Mod.EventHandler; import net.minecraftforge.fml.common.SidedProxy; import net.minecraftforge.fml.common.event.FMLInitializationEvent; import net.minecraftforge.fml.common.event.FMLPostInitializationEvent; import net.minecraftforge.fml.common.event.FMLPreInitializationEvent; import net.minecraftforge.fml.common.eventhandler.SubscribeEvent; import net.minecraftforge.fml.common.gameevent.TickEvent; import util.Reference; @EventBusSubscriber @Mod(modid=Reference.MODID, name=Reference.MODNAME, version=Reference.VERSION) public class Main { public static Configuration config; //public static int time = 10; public static Main instance; //float lastMessageTime = 0; public boolean inventoryIsFull; public static final String CLIENT = "gess.mod.proxy.ClientProxy"; public static final String SERVER = "gess.mod.proxy.CommonProxy"; @SidedProxy(clientSide = Reference.CLIENT, serverSide = Reference.COMMON) public static iProxy proxy; @EventHandler public void preInit(FMLPreInitializationEvent e){ //File directory = event.getModConfigurationDirectory(); //config = new Configuration(new File(directory.getPath(), "FullInventoryChecker.cfg")); //Config.readConfig(); } @EventHandler public void init(FMLInitializationEvent e){} @EventHandler public void postInit(FMLPostInitializationEvent e){ // if (config.hasChanged()) // config.save(); //} } public void log() { System.out.println("Does PckUpItm actually output anything?"); } private ItemStack[] previous; private ItemStack[] now; private EntityPlayer playerEntity; final EntityPlayer player = (EntityPlayer)Minecraft.getMinecraft().player; @SubscribeEvent public void PckUpItm(TickEvent.ClientTickEvent event) { if(Minecraft.getMinecraft().player != null) { this.playerEntity = player; this.previous = new ItemStack[player.inventory.getSizeInventory()]; Main pui = new Main(); pui.log(); EntityPlayer player = Minecraft.getMinecraft().player; int g = 0; System.out.println("starting to count e"); for(int e=0; e < 36; e++) { System.out.println("checking slot " + e); ItemStack stack = player.inventory.getStackInSlot(e); if(ItemStack.areItemStacksEqual(previous[e], stack)) { if(!stack.isEmpty() && stack.getCount() == stack.getMaxStackSize()) { g++; System.out.println("g = " + g); previous[e] = stack; System.out.println("Itemstack " + e + "copied"); if(g > 34) { Minecraft.getMinecraft().player.sendMessage(new TextComponentString("Your inventory is full")); return; } } } } } } @SubscribeEvent public static void chkInv(TickEvent.ClientTickEvent event) throws InterruptedException { if(Minecraft.getMinecraft().player != null) { int s = 0; for(int i=0; i < 37; i++) { if(!Minecraft.getMinecraft().player.inventory.getStackInSlot(i).isEmpty() && Minecraft.getMinecraft() .player.inventory.getStackInSlot(i).getCount() == Minecraft.getMinecraft().player.inventory.getStackInSlot(i).getMaxStackSize()) { s++; if(s > 35) { if(Minecraft.getMinecraft().world.getTotalWorldTime() % 200 == 3L && event.phase == TickEvent.Phase.END) { Minecraft.getMinecraft().player.sendMessage(new TextComponentString("Your inventory is full")); System.out.println("chkInv: Triggerred with s = " + s); return; } } } } return; } } } log timeout: [04:19:47] [main/INFO] [GradleStart]: Extra: [] [04:19:47] [main/INFO] [GradleStart]: Running with arguments: [--userProperties, {}, --assetsDir, C:/Users/[user]/.gradle/caches/minecraft/assets, --assetIndex, 1.12, --accessToken{REDACTED}, --version, 1.12.2, --tweakClass, net.minecraftforge.fml.common.launcher.FMLTweaker, --tweakClass, net.minecraftforge.gradle.tweakers.CoremodTweaker] [04:19:47] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [04:19:47] [main/INFO] [LaunchWrapper]: Using primary tweak class name net.minecraftforge.fml.common.launcher.FMLTweaker [04:19:47] [main/INFO] [LaunchWrapper]: Loading tweak class name net.minecraftforge.gradle.tweakers.CoremodTweaker [04:19:47] [main/INFO] [LaunchWrapper]: Calling tweak class net.minecraftforge.fml.common.launcher.FMLTweaker [04:19:47] [main/INFO] [FML]: Forge Mod Loader version 14.23.5.2768 for Minecraft 1.12.2 loading [04:19:47] [main/INFO] [FML]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_212, running on Windows 8.1:amd64:6.3, installed at C:\Program Files\Java\jre1.8.0_212 [04:19:47] [main/ERROR] [FML]: Apache Maven library folder was not in the format expected.

I had followed a tutorial for another mod before that one, it was using 1.12.1 version, since no stable version of 1.12.2 was available in forge mod builder (discovered it after rewatching the vid)

Code from the 1.12.2 version of InventorySpam by gigahertz https://pastebin.com/WtPT3CYT

thought it would have worked since it come from the 1.12.2 of inventoryspam (not available on github) that i reversed engineered, what should i initialize it with? EDIT: i can go on the server without it crashing now, however, i can't do anything cause i timeout around .5s after being able to move around and in solo, the method doesn't even run EDIT n°2: deleting the static, prevent the crash, not the timeout

i don't only use it to store size but the itemstack infos in itself, should i reset it to null? why would it be always true? if a stack is different, it should be true yes, but if it's the same, it's false, isn't it? if i use your method, how should i make it more precise? i mean, will it consider 2 differents heads as the same?

so i fixed the first issue by redoing the setup, this time in the recommended 1.12.2 forge build. The issue with events is gone, now, i trying to debug my code, and when connecting to the server, the client crash cause of this line : if(previous[e] != stack) { i can't see what's wrong here, did someone cursed me with blindness 255 for infinity?

hey, i'm back, to ask one question : i'm trying to make e.entity work, but "e" cannot be resolved, so i assume there is a way to make it work, but from what i saw in other mods, it just work, normally, so why isn't it working in mine? EDIT: something might have happened cause i see this : event.getEntityPlayer()or other such things related to minecraft doesn't work anymore event also doesn't work in any of my project anymore MOAR EDIT: using a method that compare items in inventory with a previous one, it doesn't work, like it doesn't even trigger : private ItemStack[] previous; private ItemStack[] now; @SubscribeEvent public void PckUpItm(TickEvent.ClientTickEvent event) { if(Minecraft.getMinecraft().player != null) { EntityPlayer player = Minecraft.getMinecraft().player; int g = 0; System.out.println("starting to count e"); for(int e=0; e < 36; e++) { System.out.println("checking slot " + e); ItemStack stack = player.inventory.getStackInSlot(e); if(previous[e] != stack) { if(!stack.isEmpty() && stack.getCount() == stack.getMaxStackSize()) { g++; System.out.println("g = " + g); previous[e] = stack; System.out.println("Itemstack " + e + "copied"); if(g > 34) { Minecraft.getMinecraft().player.sendMessage(new TextComponentString("Your inventory is full")); return; } } } } } }
