NotSoLegacy

I want to expand the capabilities of one mod. Here is a fragment of his code that interests me: @SubscribeEvent(priority = EventPriority.HIGHEST) public static void cancelDamageSource(LivingAttackEvent event) { EntityLivingBase entity = event.getEntityLiving(); DamageSource source = event.getSource(); EntityConfig config = ModConfigs.entityConfigs; ResourceLocation entityName = Utils.getEntityName(entity); Set<String> sourcesToCancel = new HashSet<>(); sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, null))); if (source.getTrueSource() != null) { sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, Utils.getEntityName(source.getTrueSource())))); } if (source.getImmediateSource() != null) { sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, Utils.getEntityName(source.getImmediateSource())))); } if (sourcesToCancel.contains(source.getDamageType())) { event.setCanceled(true); } } The result of this block of code is event.setCanceled(true);, meaning the creature will not take damage from the attack. But instead of completely canceling the damage, I want the entity to take more damage. I thought that immediately after canceling the previous damage event, I could create a new one with an increased damage value. I wrote @SubscribeEvent(priority = EventPriority.HIGHEST) public static void cancelDamageSource(LivingAttackEvent event) { EntityLivingBase entity = event.getEntityLiving(); DamageSource source = event.getSource(); float amount = event.getAmount(); EntityConfig config = ModConfigs.entityConfigs; ResourceLocation entityName = Utils.getEntityName(entity); Set<String> sourcesToCancel = new HashSet<>(); sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, null))); if (source.getTrueSource() != null) { sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, Utils.getEntityName(source.getTrueSource())))); } if (source.getImmediateSource() != null) { sourcesToCancel.addAll(config.damagesToCancel.get(Pair.of(entityName, Utils.getEntityName(source.getImmediateSource())))); } if (sourcesToCancel.contains(source.getDamageType())) { event.setCanceled(true); new LivingAttackEvent(entity, source, amount * 7); } } But the last line has no effect on the game: the damage is blocked and no new damage is dealt. What is my mistake and how can I achieve the desired result?

Oh, the problem really was in the import. But now other problems have appeared: (i can't post it, my message mark as spam) I'm guessing most of the problems stem from the fact that this code is provided in the absence of other code that it references. Here is the /give command code taken out of context: package com.purplerupter.survivalreward.command; import java.util.List; import net.minecraft.command.CommandBase; import net.minecraft.entity.item.EntityItem; import net.minecraft.entity.player.EntityPlayerMP; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.server.MinecraftServer; public class CommandGive extends CommandBase { public String getCommandName() { return "give"; } /** * Return the required permission level for this command. */ public int getRequiredPermissionLevel() { return 2; } public String getCommandUsage(ICommandSender par1ICommandSender) { return par1ICommandSender.translateString("commands.give.usage", new Object[0]); } public void processCommand(ICommandSender par1ICommandSender, String[] par2ArrayOfStr) { if (par2ArrayOfStr.length >= 2) { EntityPlayerMP var3 = func_82359_c(par1ICommandSender, par2ArrayOfStr[0]); int var4 = parseIntWithMin(par1ICommandSender, par2ArrayOfStr[1], 1); int var5 = 1; int var6 = 0; if (Item.itemsList[var4] == null) { throw new NumberInvalidException("commands.give.notFound", new Object[] {Integer.valueOf(var4)}); } else { if (par2ArrayOfStr.length >= 3) { var5 = parseIntBounded(par1ICommandSender, par2ArrayOfStr[2], 1, 64); } if (par2ArrayOfStr.length >= 4) { var6 = parseInt(par1ICommandSender, par2ArrayOfStr[3]); } ItemStack var7 = new ItemStack(var4, var5, var6); EntityItem var8 = var3.dropPlayerItem(var7); var8.delayBeforeCanPickup = 0; notifyAdmins(par1ICommandSender, "commands.give.success", new Object[] {Item.itemsList[var4].func_77653_i(var7), Integer.valueOf(var4), Integer.valueOf(var5), var3.getEntityName()}); } } else { throw new WrongUsageException("commands.give.usage", new Object[0]); } } /** * Adds the strings available in this command to the given list of tab completion options. */ public List addTabCompletionOptions(ICommandSender par1ICommandSender, String[] par2ArrayOfStr) { return par2ArrayOfStr.length == 1 ? getListOfStringsMatchingLastWord(par2ArrayOfStr, this.getPlayers()) : null; } protected String[] getPlayers() { return MinecraftServer.getServer().getAllUsernames(); } /** * Return whether the specified command parameter index is a username parameter. */ public boolean isUsernameIndex(int par1) { return par1 == 0; } }

Introduction: I'm developing a modpack for version 1.12.2, it contains a lot of mods, interaction with some mods is only possible through commands. If players are prohibited from using cheats, they still have access to some harmless commands, such as /seed and the schematic mod commands. But there are also some informative commands - they simply display information in the chat for the player who type it, they do not give an unfair advantage, unlike /give, /gamemode, /teleport commands, but nevertheless they are prohibited when playing without cheats. One such command is /srpevolution getphase from the SRParasites mod. The FTB utilities mod should solve my problem, but it doesn't work (https://github.com/FTBTeam/FTB-Mods-Issues/issues/1124). So I thought about writing my own mod. However, before this I had never developed mods for Minecraft. The essence of the problem: I want to write a mod that, based on data from the config, will add commands to the game that are available to players when playing without cheats. All these commands will do is call commands from other mods (for example /srpevolution getphase - that is, include commands consisting of several words), which are not available to players by default. I tried to find the documentation https://docs.minecraftforge.net/en/1.12.x/search.html?q=command, but did not find a page describing adding commands to the mod, I found only a page about permissions and unrelated pages. I tried to find information on this forum, but found information that is not relevant for 1.12.2 (either too old or too new). After copying the complete code, I received many red errors such as public class CommandGive extends CommandBase Cannot resolve symbol 'CommandBase'".
