Ok, I dont get the crash anymore when I join. Everything seems working right now, 

I returned

LazyOptional.of(() -> INSTANCE).cast();

https://github.com/cinsiian/mod/tree/master/java/cinsiian/urtima/common/capability/mana

Thats the full package related to mana, everything should be ok.

Now I will start working on the Bar in the RenderGameOverlayEvent.

Is RenderGameOverlayEvent executed every tick? I will check every tick:

if the mana is 20 I render a thing, if its 19 render another thing ecc...

What part of "create it ONCE" did you not understand?

I dont have another instance of it

....so create one? Like, how hard is it to do this:

Oh ok ill' do it but whats the difference?

Ok so I managed to get the event work but the texture is not rendering correctly:

public final ResourceLocation TEXTURE = new ResourceLocation(Reference.MODID, "textures/gui/mana_hud.png");
   @SubscribeEvent
	public void renderOverlay(RenderGameOverlayEvent event) {	
		if(event.getType() == ElementType.AIR) {
			Minecraft mc = Minecraft.getInstance();
			int x = event.getWindow().getScaledWidth() / 2 + 10;
			int y = event.getWindow().getScaledHeight() - 48;
			if(!(mc.player.isSpectator() || mc.player.isCreative())) {
				mc.getTextureManager().bindTexture(TEXTURE);
				drawBackground(x, y);
			}
		}
	}
	
	private void drawBackground(int x, int y) {
		drawTexturedModalRect(x, y, 0, 0, 89, 9);
	}
	
	private void drawTexturedModalRect(int x, int y, int textureX, int textureY, int width, int height) {
		Minecraft mc = Minecraft.getInstance();
	    mc.ingameGUI.blit(x, y, textureX, textureY, width, height);
	}

What are the RenderGameOverlayEvent.Pre and RenderGameOverlayEvent.Post ?

Is that event executed every tick?

I think Gui#blit expects the texture to be 256x256

Thank you guys, now textures work perfectly but I have few last things to ask.

1) How can I see if the air bubble bar is rendered(so i can move the mana bar up so it does not contrast)?

2) What is the correct way to get/set the capability?, I used:

player.getCapability(ManaProvider.MANA, null).orElseThrow(null).get()
player.getCapability(ManaProvider.MANA, null).orElseThrow(null).set()

It's really buggy, sometimes it doesnt even do anything

you could check if the player is inside water i think there was a way to get if the player is underwater

there is Player.isSwimming but I also need if the player is underwater even without swimming

try EntityPlayer#isInsideOfMaterial and use Material.WATER as parameter thats the dirty way to do it but should work i think..

Use PlayerEntity#areEyesInFluid(FluidTags.WATER)

Ok, it did work but i have few issues setting up the capability adding/setting the value.

https://github.com/cinsiian/mod/blob/master/java/cinsiian/urtima/util/ManaUtils.java

 

The hud displays the correct amount of mana but when I try consuming it for some reason it return that the player does not have the correct mana amount

You need a packet to sync the data you can read up about packets on the forge documentation.

So basically what I did is this and seems that its working.

public static void updateMana(PlayerEntity player) {
		IMana oldMana = ManaUtils.getMana(Minecraft.getInstance().player);
		IMana newMana = ManaUtils.getMana(player);
		
		if(oldMana != null && newMana != null) {
			oldMana.set(newMana.get());
		}
	}

 

Basically if its the same player, it will take the data from the server(ManaUtils methods) and update them to the client player(Minecraft.getInstance().player).

I tried to do that...

Can someone explain how to use the network system? I tried to get it work with the documentation as a reference  without success.

https://github.com/Draco18s/ReasonableRealism/blob/1.14.4/src/main/java/com/draco18s/harderores/network/PacketHandler.java#L12

Namely you just say "here's my packet class's constructor, toBytes, fromBytes, etc." You can call those methods whatever you want as long as they have the right signature.

ok but how do i actually set the client mana? In the packet's Handler?

https://github.com/Draco18s/ReasonableRealism/blob/1.14.4/src/main/java/com/draco18s/harderores/network/ToClientMessageOreParticles.java#L54 Like here?

And how can I get the serverplayer? Do I have to save it in the packet as well?

 

you can get the player from the context

Supplier<NetworkEvent.Context> ctx

?

What handler? The handler of the actual packet or the handler of the network?

So the packet will be(Server-ToClient):

public class ManaPacket {
	
	public int mana;
	
	public ManaPacket() {}
	
	public ManaPacket(int mana) {
		this.mana = mana;
	}
	
	public static void writeIn(ManaPacket packet, PacketBuffer buffer) {
		buffer.writeInt(packet.mana);
	}
	
	public static ManaPacket readIn(PacketBuffer buffer) {
		return new ManaPacket(buffer.readInt());
	}
	
	public static class PacketHandler {
		public static void run(final ManaPacket packet, Supplier<NetworkEvent.Context> context) {
			context.get().enqueueWork(() -> {
				int i = context.get().getSender().getCapability(ManaProvider.MANA, null).orElseThrow(null).get();
				packet.mana = i;
			});
		}
	}

}
