Thanks! Works now.

I have a float Capabilty for players and I have it so that it increases by 0.05 when a certain item is used. But when I use the item it does not increase exactly. (For example, instead of going from 1.05 to 1.1, it goes to 1.0999999). How would I fix this? Relevant code: // SkillLevel.java public class SkillLevel implements ISkillLevel { private float level = 1F; @Override public void remove(float num) { this.level -= num; } @Override public void add(float num) { this.level += num; } @Override public void set(float num) { this.level = num; } @Override public float getLevel() { return this.level; } public static class SkillLevelProvider implements ICapabilitySerializable<FloatNBT> { @CapabilityInject(ISkillLevel.class) public static Capability<ISkillLevel> SKILL_CAP; private LazyOptional<ISkillLevel> instance = LazyOptional.of(SKILL_CAP::getDefaultInstance); @Nonnull @Override public <T> LazyOptional<T> getCapability(@Nonnull Capability<T> cap, @Nullable Direction side) { return SKILL_CAP.orEmpty(cap, instance); } @Override public FloatNBT serializeNBT() { return (FloatNBT) SKILL_CAP.getStorage().writeNBT(SKILL_CAP, instance.orElseThrow(() -> new IllegalArgumentException("LazyOptional cannot be empty!")), null); } @Override public void deserializeNBT(FloatNBT nbt) { SKILL_CAP.getStorage().readNBT(SKILL_CAP, instance.orElseThrow(() -> new IllegalArgumentException("LazyOptional cannot be empty!")), null, nbt); } } @Override public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) { ISkillLevel skill = playerIn.getCapability(SkillLevel.SkillLevelProvider.SKILL_CAP).orElse(null); skill.add(0.05f); System.out.println(skill.getLevel()); } Thanks!

Thanks! Looks perfect!

I would like to create a points system where a player has to have a certain amount of points to do a special ability. What is the best way to store these points? I thought of NBT tags or a json file but I don't know the best method

Where would I call it from? Is there a method for it?

Thanks so much! And how would I make it get the tags from the /give command?

How would I implement this? I have this: @Override public void fillItemGroup(ItemGroup group, NonNullList<ItemStack> items) { if (this.isInGroup(group)) { ItemStack stack = new ItemStack(this); CompoundNBT nbt = stack.getOrCreateTag(); TestMod.LOGGER.info(stack.getTag()); ListNBT bookPages = new ListNBT(); String[] values = {"test", "test2", "test3", "test4"}; for (String text : values) { bookPages.add(StringNBT.valueOf("{\"text\":\"" + text + "}\""));} nbt.put("pages", bookPages); nbt.putString("author", "Test Author"); nbt.putString("title", "Test Title"); TestMod.LOGGER.info(stack.hasTag()); TestMod.LOGGER.info(stack.getTag()); TestMod.LOGGER.info(nbt); items.add(new ItemStack(this, 1, nbt)); } } But still doesn't work

I have made a custom boom item and I would like to add default NBT data: the author the title and the pages. This is my code: package com.scottbot.testmod.objects.items; import com.scottbot.testmod.TestMod; import com.scottbot.testmod.gui.ModBookReadScreen; import net.minecraft.client.Minecraft; import net.minecraft.client.util.ITooltipFlag; import net.minecraft.entity.player.PlayerEntity; import net.minecraft.item.Item; import net.minecraft.item.ItemStack; import net.minecraft.item.WrittenBookItem; import net.minecraft.nbt.CompoundNBT; import net.minecraft.nbt.ListNBT; import net.minecraft.nbt.StringNBT; import net.minecraft.util.ActionResult; import net.minecraft.util.Hand; import net.minecraft.util.StringUtils; import net.minecraft.util.text.ITextComponent; import net.minecraft.util.text.TextFormatting; import net.minecraft.util.text.TranslationTextComponent; import net.minecraft.world.World; import javax.annotation.Nullable; import java.util.List; public class ModBookItem extends WrittenBookItem { public ModBookItem(Properties builder) { super(builder); ItemStack stack = new ItemStack(this); TestMod.LOGGER.info("tagging"); addTags(stack); } public void addTags(ItemStack stack) { CompoundNBT nbt = stack.getOrCreateTag(); TestMod.LOGGER.info(stack.getTag()); ListNBT bookPages = new ListNBT(); String[] values = {"test", "test2", "test3", "test4"}; for (String text : values) { bookPages.add(StringNBT.valueOf("{\"text\":\"" + text + "}\""));} nbt.put("pages", bookPages); nbt.putString("author", "Test Author"); nbt.putString("title", "Test Title"); stack.setTag(nbt); TestMod.LOGGER.info(stack.hasTag()); TestMod.LOGGER.info(stack.getTag()); } @Override public void onCreated(ItemStack stack, World worldIn, PlayerEntity playerIn) { addTags(stack); super.onCreated(stack, worldIn, playerIn); } @Override public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) { ItemStack stack = playerIn.getHeldItem(handIn); Minecraft.getInstance().displayGuiScreen(new ModBookReadScreen(new ModBookReadScreen.WrittenBookInfo(stack))); return ActionResult.resultSuccess(stack); } @Override public void addInformation(ItemStack stack, @Nullable World worldIn, List<ITextComponent> tooltip, ITooltipFlag flagIn) { TestMod.LOGGER.info(stack.getTag()); TestMod.LOGGER.info(stack.hasTag()); if (stack.hasTag()) { CompoundNBT compoundnbt = stack.getTag(); TestMod.LOGGER.info(compoundnbt); assert compoundnbt != null; String s = compoundnbt.getString("author"); TestMod.LOGGER.info(s); if (!StringUtils.isNullOrEmpty(s)) { tooltip.add((new TranslationTextComponent("book.byAuthor", s)).applyTextStyle(TextFormatting.GRAY)); } } } When I start the game, it logs that the tags were added: But when I actually get it from the creative menu it doesn't have the author tag and when I open the book it says invalid tag. Any help would be appreciated, thanks!

Where do I get GuiScreen? I couldn't find a class called GuiScreen, only GuiScreenEvent.

So I have an class extending Item and would like to add a tooltip when SHIFT is pressed while mousing over the item. I have the addInformation method but I don't know how to check if a key is pressed down. Thanks in advance

I am making a mod that I can use on servers and what I would like to do is monitor the messages being sent by the player and if they contain a certain string to not send them. For example if it has bad language it will prevent it from being sent. I could not find an event for this, only for receiving chat and not for sending it. I am new to modding and any help would be appreciated. Thanks!
