[1.15.2]How do I fire events?


kyazuki

Recommended Posts

My mod changes player's height on every tick.

So I use EntityEvent.EyeHeight#SetNewHeight method.

I want to fire the event on every tick.

This cord doesn't work.

What's wrong?

@SubscribeEvent
  public static void sethitboxPlayer(TickEvent.PlayerTickEvent event) {
    float hitboxScale = event.player.getHeight() * scale;
    AxisAlignedBB playerBoundingBox = event.player.getBoundingBox();
    event.player.setBoundingBox(new AxisAlignedBB(playerBoundingBox.minX, playerBoundingBox.minY, playerBoundingBox.minZ, playerBoundingBox.maxX, playerBoundingBox.minY + hitboxScale, playerBoundingBox.maxZ));
    
    Pose pose = event.player.getPose();
    EntitySize size = event.player.getSize(pose);
    net.minecraftforge.event.entity.EntityEvent.EyeHeight evt = new net.minecraftforge.event.entity.EntityEvent.EyeHeight(event.player, pose, size, event.player.getEyeHeight(pose));
    net.minecraftforge.common.MinecraftForge.EVENT_BUS.post(evt);
  }

Just because you fired the event doesn't mean Forge is listening. And Forge is never listening to its own events. Events are for mods to listen to and do what they want.

 

(read: that's not how you set the eye height)

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

Sorry for my lack of explanation.

I set the eye height by this cord.

It works, but it fires only when the pose changes.

Can't I fire Forge events manually in my mod?

@SubscribeEvent
  public static void setEyePlayer(EntityEvent.EyeHeight event) {
    if (event.getEntity() instanceof PlayerEntity) {
      PlayerEntity player = (PlayerEntity) event.getEntity();
      event.setNewHeight(event.getOldHeight() * scale);
    }
  }

You can; however, that is not what you want to do in this case.

Why do you want to change the eye height every tick? What are you trying to achieve?

AFAIK you only need to change the eye height when the event fires, as the event is used for all cases of determining an entity's eye height.

I think there are a few exceptions such as ForgeInternalHandler.

Yes you can. However you fire the event and your event only sets the events new height. It doesn't actually set the eye height. When the event is normally fired you'll notice that after it has fired forge takes the new eye height from the event and uses that.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

Fair enough, but in general, Forge fires events and doesn't listen for them.

My mod makes player tall as the player walks.

@SubscribeEvent
  public static void calc(TickEvent.PlayerTickEvent event) {
    if (!event.player.world.isRemote()) {
      walkDistance = event.player.distanceWalkedModified / 0.6f;
      scale = walkDistance * 0.001f + minScale;
    }
  }

However, I can't access player's height.

So I change render scale, hitbox and eye height.

@SubscribeEvent
  public static void onRenderPlayerPre(RenderPlayerEvent.Pre event) {
    event.getMatrixStack().push();
    event.getMatrixStack().scale(1.0f, scale, 1.0f);
  }

  @SubscribeEvent
  public static void onRenderPlayerPost(RenderPlayerEvent.Post event) {
    event.getMatrixStack().pop();
  }
@SubscribeEvent
  public static void sethitboxPlayer(TickEvent.PlayerTickEvent event) {
    float hitboxScale = event.player.getHeight() * scale;
    AxisAlignedBB playerBoundingBox = event.player.getBoundingBox();
    event.player.setBoundingBox(new AxisAlignedBB(playerBoundingBox.minX, playerBoundingBox.minY, playerBoundingBox.minZ, playerBoundingBox.maxX, playerBoundingBox.minY + hitboxScale, playerBoundingBox.maxZ));
    //Fire EyeHeightEvent
  }
@SubscribeEvent
  public static void setEyePlayer(EntityEvent.EyeHeight event) {
    if (event.getEntity() instanceof PlayerEntity) {
      PlayerEntity player = (PlayerEntity) event.getEntity();
      event.setNewHeight(event.getOldHeight() * scale);
    }
  }

You can subscribe to PlayerTickEvent and manually change Entity::eyeHeight to fit your need. After that, simply simulate what Entity#recalculateSize does on the PlayerEntity.

    • I changed it to public static void but I can't find anyway to get level from the event even if it isn't a listener parameter. @JimiIT92
    • I didn't yet see this happening on 1.20.2 forge, but sadly, I noticed that my mod is incompatible with this version because of this event handler: @SubscribeEvent public static void onPlayerRightClickItem(PlayerInteractEvent.RightClickItem e) { if (e.getItemStack().getItem() instanceof EggItem) { List<ThrownEgg> eggs = e.getLevel().getEntitiesOfClass(ThrownEgg.class, new AABB(e.getEntity().blockPosition().immutable() .below(5) .north(5) .west(5), e.getEntity().blockPosition().immutable() .above(10) .south(5) .east(5))); if (!eggs.isEmpty()) { eggs.forEach(ThrownEgg::discard); if (!e.getEntity().getAbilities().instabuild) e.getItemStack().grow(1); } if (!e.getEntity().level().isClientSide) { ((ServerPlayer) e.getEntity()).connection.send( new ClientboundStopSoundPacket(SoundEvents.EGG_THROW.getLocation(), SoundSource.PLAYERS)); // Minecraft Forge 1.20.2 crashes because of NoSuchMethodError here } e.setCancellationResult(InteractionResult.SUCCESS); e.setCanceled(true); } }  
    • It might just be a misleading log, if you run the command while debugging what's the outcome?  I've tried checking the item inside the RightClickBlock event and it works just fine private static final Ingredient FOOD_ITEMS = Ingredient.of(Items.WHEAT_SEEDS, Items.MELON_SEEDS, Items.PUMPKIN_SEEDS, Items.BEETROOT_SEEDS, Items.TORCHFLOWER_SEEDS, Items.PITCHER_POD); @SubscribeEvent public static void onRightClickBlock(final PlayerInteractEvent.RightClickBlock event) { final ItemStack itemStack = event.getItemStack(); LOGGER.info(FOOD_ITEMS.test(itemStack) + ""); } When I right click a block with an Item it checks if is one of the ingredients of FOOD_ITEMS. Clicking with an empty hand (air) logs false, as expected. Tip: please use the "spoiler" tags for long code snippets and don't merge all your classes into one code snippet EDIT: just noticed you are on 1.20.1. Maybe is just a bug with the Forge version? Try update to the latest Forge 1.20.2 and see if it still occurs
    • I created a temp command with this syntax: /isfood <entity to check> <player to check the item in main hand or off hand> It outputs either string respiration of an ItemStack (<count of items> <item name>) that player holds in his hand if it's a food item for specified entity, or "none" if specified player isn't holding an item which is a food item for the specified entity. Command's code if you didn't understand: event.getDispatcher().register(Commands.literal("isfood").then(Commands.argument("animal", EntityArgument.entity()) .then(Commands.argument("player", EntityArgument.player()).executes(context -> { Entity entity = EntityArgument.getEntity(context, "animal"); Player player = EntityArgument.getPlayer(context, "player"); if (entity instanceof Animal mob) { if (mob.isFood(player.getItemInHand(InteractionHand.MAIN_HAND))) context.getSource().sendSuccess(() -> Component.literal(String.valueOf( player.getItemInHand(InteractionHand.MAIN_HAND))), true); else if (mob.isFood(player.getItemInHand(InteractionHand.OFF_HAND))) context.getSource().sendSuccess(() -> Component.literal(String.valueOf( player.getItemInHand(InteractionHand.OFF_HAND) )), true); else context.getSource().sendSuccess(() -> Component.literal("none"), true); } return 1; })))); So, I tested it on my entity, and command output was: 0 air (also want to say that it happens only if I play Minecraft for a long time) Anyways, the entity code: package mymod.entities.chicken;
