I am trying to make a level system. I have succseeded in some places but in other not. The main problem is: how to get current minecraft player, like i mean EntityPlayer.

Here is the error log: http://pastebin.com/ZMVjyjD6

This is the Gui class code:http://pastebin.com/LkVbuNQB

Before i have had 

EntityPlayer p = mc.theplayer;

but this doesn't work.

 

Example where it works:

I the Block On Activated method:

public boolean onBlockActivated(World world, int x, int y, int z,EntityPlayer p, int a, float f, float b, float c){
	nbt=p.getEntityData();
	nbt.setInteger("level", getLevel()+1);
	return true;
	}
public int getLevel() {
	return nbt.getInteger("level");
}

because here i have the EntityPlayer supplied.

Chemistryzation.java(main class):http://pastebin.com/aNg5VYCq

 

Please help!

For any useful info you will be credited!

It doesn't work because of the client-server architecture.

 

A SSP game and a SMP game with one connected user are indistinguishable.

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.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

You can, you just have to approach it differently.

 

You are going to need an event hook to listen for players joining the server, then save data into the player that way.

btw not to be mean but i suggest you attack smaller mods. This is a pretty obvious error.

can we see the class "Chemistryzation". why are you calling a gui from there ? Even worst, why is it from a method called postInit ?

1 please use spoilers,

 

2 ..................

 

 

 

 

what you are saying to the mod right now is

"oh you're initializing the server? OPEN A GUI NOW NOW NOW" which cant happen server side

 

1 make a class that implements IGuiHandler

2 register this class like this

NetworkRegistry.instance().registerGuiHandler(this, new GuiHandler());

3 make GuiChemistryLevel  extends GuiScreen instead

4 call the gui from any method (either right click a block or bind it to a key)

5 look at the wiki and tutorials.

      Reproducing F3 Entities in FOV/Entity Count 1.20.4

      By MichaelQc · Posted

      New to forge modding, I'm currently trying to make a client side only mod that basically just reproduces the numbers for entities in FOV and total entity count shown in the F3 toggle (E: # in fov/# total). Basically just trying to take these numbers and display them in the center of the screen (without having F3 open) so they can be seen constantly.Been primarily learning forge using ChatGPT but it seems to spew out incorrect code over and over again when I ask it how it would do something like this (probably confusing versions and such). Not sure if these numbers can be directly accessed or not or if its more complicated than that.   This is my current code I basically just need to implement the 2 methods at the bottom. Any info/help is appreciated. import java.util.ArrayList; import java.util.List; import java.util.stream.Collectors; import net.minecraft.client.Camera; import net.minecraft.client.Minecraft; import net.minecraft.client.gui.GuiGraphics; import net.minecraft.client.renderer.culling.Frustum; import net.minecraft.world.entity.Entity; import net.minecraft.world.phys.AABB; import net.minecraft.world.phys.Vec3; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.client.event.RenderGuiOverlayEvent; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod; import net.minecraft.world.entity.Entity; import net.minecraft.client.multiplayer.ClientLevel; @Mod.EventBusSubscriber(modid = "myforgehudmod", value = Dist.CLIENT) public class MyCustomHUD { @SubscribeEvent public static void onRenderHUD(RenderGuiOverlayEvent.Post event) { Minecraft minecraft = Minecraft.getInstance(); GuiGraphics guiGraphics = event.getGuiGraphics(); int screenWidth = minecraft.getWindow().getGuiScaledWidth(); int screenHeight = minecraft.getWindow().getGuiScaledHeight(); int totalEntities = countTotalEntities(minecraft); int entitiesInFOV = countEntitiesInFOV(minecraft); String hudText = entitiesInFOV + " / " + totalEntities; int textWidth = minecraft.font.width(hudText); int x = (screenWidth / 2) - (textWidth / 2); int y = screenHeight / 2; y = y + 10; // x,y is directly below crosshair by 10 pixels with centered text guiGraphics.drawString(minecraft.font, hudText, x, y, 0xFFFFFF); } private static int countTotalEntities(Minecraft minecraft) { return 0; } private static int countEntitiesInFOV(Minecraft minecraft) { return 0; } }

      Modpack crashes when trying to open world. Due to JurassicCraft and JurassicWorldReborn, I believe [Java] 1.12.2 Exit Code: -1

      By DavidMMTX · Posted

      Please let me know if there is a good solution: Hey Y'all, sorry to bother you, but I believe I'm getting an error between jurassicworld reborn and jurassicraft when I'm attempting to open my world. The world used to work with both mods active, and so I'm posting here to see why it doesn't work anymore, and if there is a solution to fix it that doesn't include taking out either, as doing that will take out a big part/amount of blocks out of my world. If not, then please let me know. Also, please let me know if more info is needed, as this was all of the crash report that would fit. Thanks for the help, look forward to hearing from you!
