NBT Tag Help (Fetching it Client / Server Side)

Alright, so I'm working on my mod and trying to launch a player in a certain direction. That works. However, I am only doing it when a player clicks and if they have an ability "selected". This simply checks if an ability is bound to their current slot. It is a bit complex, but I'll supply the necessary code.

 

My problem: I want to check if the player has an Ability Bound. If they do, it runs a certain block of code.

 

Here is the code that I want to run:

@ForgeSubscribe
public void onUpdate(LivingUpdateEvent e) {
	if (e.entity instanceof EntityPlayer) {
		EntityPlayer player = (EntityPlayer) e.entity;
		if (BendingPlayerTracker.benders.get(player.username) == Element.Chi) {
			if (BendingMethods.knowsMove(player, Ability.HighJump) && BendingMethods.isAbilitySelected(player, Ability.HighJump)) {
				if (player.swingProgress == 0.8333333F) {
					while (BendingMethods.isAbilitySelected(player, Ability.HighJump)) {
						double motionX = 1.0 * (double) (-MathHelper.sin(player.rotationYaw/ 180.0F * (float) Math.PI)* MathHelper.cos(player.rotationPitch / 180.0F* (float) Math.PI));
						double motionZ = 1.0 * (double) (MathHelper.cos(player.rotationYaw	/ 180.0F * (float) Math.PI)* MathHelper.cos(player.rotationPitch / 180.0F* (float) Math.PI));
						double motionY = 1.0 * (double) (-MathHelper.sin((player.rotationPitch)/ 180.0F * (float) Math.PI) );
						player.motionX = motionX;
						player.motionZ = motionZ;
						player.motionY = motionY;
					}
				}
			}
		}
	}
}

 

Everything in that chunk works except for BendingMethods.isAbilitySelected. It returns true 50% of the time, and false the other 50%. I added debug messages to get this. The Abilities and the slots they are on are stored server side. Here is the code for that:

 

public static boolean isAbilitySelected(EntityPlayer player, Ability ability) {
	NBTTagCompound nbt = player.getEntityData().getCompoundTag(player.PERSISTED_NBT_TAG);
	int slot = player.inventory.currentItem + 1;
	if (nbt.getString("BendingSlot" + slot) != null && nbt.getString("BendingSlot" + slot).equals(ability.toString())) {
		return true;
	}

	return false;
}

 

The ability selected returns true if it is run on server side I believe. When I run a command, it returns true, etc. Anyway, I think the reason it is returning true 50% of the time is because it checks if it is client side and server side (with server side returning true and client side false). Now, the player motion is client side. How do I get these to work nicely together. I can assure you that the slot is bound correctly, as I've used it plenty of times before. My problem only comes up when I'm trying to use the player.motion methods.

 

Huge thanks in advance.

    • Hello! When I'm trying to get items by tag during the recipe serialization, I'm getting an empty list. I have a guess that item tags're not loaded by the time minecraft loads my recipes. Here's my code: Class that saves information about ingredient's count Recipe serializer with some aux methods: Registry: Example of the json recipe file:  
    • I tried to install client forge on my linux desktop. But after "installation" it's missing forge[version].jar file in .minecraft/versions. I tried java 11 and 8 environment with same result. Here link to log file from installation: https://drive.google.com/file/d/1vtg9NT-WX5ilb1aNUvZlOv54gKWJuaT1/view?usp=share_link. I don't know what to do. I give for every directory permissions that I don't think that is issue. I will try check older versions if universal file work. Debian 11 (kernel 5.10)
    • I recently got error 1 in the launcher, so I restarted the .minecraft. After restarting it, I can't get the Forge 1.19.2 - 43.1.1 installer to run, I tried other versions and I get the same result, it opens a black box that closes instantly and nothing happens. I already tried to restart my pc, minecraft, update and reinstall java, run vanilla 1.19.2 and more recent versions of the game, disable Windows Firewall and antivirus and I still haven't solved it. Many times I installed forge and never ran into this problem. If I could receive assistance I would be very grateful.  
    • Here's the default loot table for gravel block: { "type": "minecraft:block", "pools": [ { "rolls": 1.0, "bonus_rolls": 0.0, "entries": [ { "type": "minecraft:alternatives", "children": [ { "type": "minecraft:item", "conditions": [ { "condition": "minecraft:match_tool", "predicate": { "enchantments": [ { "enchantment": "minecraft:silk_touch", "levels": { "min": 1 } } ] } } ], "name": "minecraft:gravel" }, { "type": "minecraft:alternatives", "conditions": [ { "condition": "minecraft:survives_explosion" } ], "children": [ { "type": "minecraft:item", "conditions": [ { "condition": "minecraft:table_bonus", "enchantment": "minecraft:fortune", "chances": [ 0.1, 0.14285715, 0.25, 1.0 ] } ], "name": "minecraft:flint" }, { "type": "minecraft:item", "name": "minecraft:gravel" } ] } ] } ] } ] } This is a finicky loot table. If I add anything to it, nothing drops. I've added pools, entries, children ... you name it. Does anyone know the particulars about this table? I mean, periodically gravel drops flint instead of a gravel block. I understand the condition that could drop flint if the block survives an explosion. Otherwise, it drops the gravel block itself. I would like to further understand why the use of `children` and the set of `chance` values given in the explosion child entry. What I do understand is that `"type" : "minecraft:alternatives"` means that if this child/entry is successful, then it stops generating loot for this entry/pool. How often does the flint drop and is that taken care of in another location? Is that in a `"condition" : "minecraft:table_bonus"` loot table? Hmmm... I'll have to go take a look and see if there is something called table_bonus.json.
