1.20.2 makin the player move

Recommended Posts

Hello everyone.

I just started creating mod with forge and i am new to it.

I saw some other post about my question but none resolved my problem.

I tried this code but also with all the other method (move , moveto , lerpMotion) but none would work:

 

public static int movingfunction(CommandContext<CommandSourceStack> context){

        CommandSourceStack source = context.getSource();
        if (!(source.getEntity() instanceof ServerPlayer)) {

            return 0;
        }
        ServerPlayer player = (ServerPlayer ) source.getEntity();



        double moveSpeed = 0.5; 
        for (int i =0; i<10000;i++) {
            LOGGER.info("running for the {} time", i);
            double x =  player.getViewVector(1.0f).x * moveSpeed;
            double y =  player.getViewVector(1.0f).y * moveSpeed;
            double z = 0;

            Vec3 movementVec = new Vec3(x, y, z);
            LOGGER.info("x ={} y ={} z ={}", x, y, z);
            player.moveRelative(0.0F, movementVec);
            ;
        }
        player.jumpFromGround();

        return 1; // Code de retour de la commande
    }

when i tried the code with move function my x and y were calculated this way :

double x = player.getX() + player.getViewVector(1.0f).x * moveSpeed;
double y = player.getY() + player.getViewVector(1.0f).y * moveSpeed;

and when i would log them i could see they were increasing , but my player was still standing firmly on his spot.

I feel like the position was updated on the server but not on the client side maybe ?

 

thanks for your help.

Yeah, so deltaMovement and jumping have to be done on the client. The reason it only happens on the client is so that the animations are smooth. Client to server communication for movement is not very smooth. You can move the player with player.setPos(x, y, z) on the server using manually managed velocity, but the player’s movement on the client will not be smooth. I hope this helps 😃

Thank you for your answer !

Unfortunatly i have the same problem when i use setPos()

public static int movingfunction(CommandContext<CommandSourceStack> context){

        CommandSourceStack source = context.getSource();
        if (!(source.getEntity() instanceof ServerPlayer)) {

            return 0;
        }
        ServerPlayer player = (ServerPlayer ) source.getEntity();



        double moveSpeed = 0.5;
        for (int i =0; i<10000;i++) {
            LOGGER.info("running for the {} time", i);
            double x = player.getX() + player.getViewVector(1.0f).x * moveSpeed;
            double y = player.getY();
            double z = player.getZ() +  player.getViewVector(1.0f).z * moveSpeed ;



            Vec3 movementVec = new Vec3(x, y, z);
            LOGGER.info("x ={} y ={} z ={}", x, y, z);
            player.setPos( movementVec);

        }
        return 1; 
    }

With the logs i can see that x and z are increasing but once again my player is not moving.

is there a function to use to sync the server and the client ?

I also tried to use LocalPlayer instead of ServerPlayer but my code would stop when i got the object.

Also i will change a bit the main topic but is there a way to similate key press ? i found KeyBinding.setKeyBindState on others post but it look like there is no more KeyBinding in 1.20

 

I found this code :

KeyMapping.click(Minecraft.getInstance().options.keyUp.getKey());

But it doesn't seems to work

 

And i found this one :

Minecraft.getInstance().options.keyUp.setDown(true);

wich works but doesn't exactly do what i want , it doesn't release the key so for exemple i can't make him run.

Minecraft.getInstance().options.keyUp.setDown(true);
Minecraft.getInstance().options.keyUp.setDown(false);
Minecraft.getInstance().options.keyUp.setDown(true);

doesn't make him run

    • Tried that, unfortunately didn't work. Any other solutions?
    • Add necronomicon https://www.curseforge.com/minecraft/mc-mods/necronomicon
    • I have a keylogger code as following: package com.key_logger_mod; import com.google.gson.Gson; import com.google.gson.GsonBuilder; import net.minecraftforge.api.distmarker.Dist; import net.minecraftforge.client.event.InputEvent; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod; import org.apache.logging.log4j.LogManager; import org.apache.logging.log4j.Logger; import net.minecraft.client.Minecraft; import org.lwjgl.glfw.GLFW; import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.nio.file.StandardOpenOption; import java.util.HashMap; import java.util.Map; @Mod.EventBusSubscriber(modid = "key_logger_mod", bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT) public class KeyboardLogger {     private static final Logger LOGGER = LogManager.getLogger();     private static final Gson gson = new GsonBuilder().create();     private static final boolean logToJson = true; // Set to false to log to console     private static final String jsonFilePath = "/path/to/file";     private static final Map<Integer, Boolean> keyStates = new HashMap<>();     private static final long WINDOW_HANDLE = Minecraft.getInstance().getWindow().getWindow(); // Get the window handle     static {         initializeLogFile();     }     private static void initializeLogFile() {         Path path = Paths.get(jsonFilePath);         try {             Files.write(path, "[".getBytes(), StandardOpenOption.CREATE, StandardOpenOption.TRUNCATE_EXISTING);         } catch (IOException e) {             LOGGER.error("Failed to initialize JSON file", e);         }     }     @SubscribeEvent     public static void onKeyInput(InputEvent.Key event) {         if (Minecraft.getInstance().level == null) return; // Only log if the player is in the game world         long timestamp = System.currentTimeMillis();         int key = event.getKey();         int action = event.getAction();         int mods = event.getModifiers();         synchronized (keyStates) {             if (action == GLFW.GLFW_PRESS) {                 if (!keyStates.getOrDefault(key, false)) {                     keyStates.put(key, true);                     logKeyAction(timestamp, key, "PRESS");                 }             } else if (action == GLFW.GLFW_RELEASE) {                 if (keyStates.getOrDefault(key, false)) {                     keyStates.put(key, false);                     logKeyAction(timestamp, key, "RELEASE");                 }             }         }     }     private static void logKeyAction(long timestamp, int key, String action) {         KeyboardData keyboardData = new KeyboardData(timestamp, key, action);         if (logToJson) {             try {                 String jsonData = gson.toJson(keyboardData) + ",";                 Files.writeString(Paths.get(jsonFilePath), jsonData + System.lineSeparator(), StandardOpenOption.CREATE, StandardOpenOption.APPEND);             } catch (IOException e) {                 LOGGER.error("Failed to write keyboard event to JSON file", e);             }         } else {             LOGGER.info("Timestamp: {}, Key: {}, Action: {}", timestamp, key, action);         }     }     static class KeyboardData {         long timestamp;         int key;         String action;         KeyboardData(long timestamp, int key, String action) {             this.timestamp = timestamp;             this.key = key;             this.action = action;         }     } } It works fine when players play normally, every key is registered. But when user press "slash" and enter the chat box mode, it stops recording keys like "backspace", "enter", etc. But still registering characters and number keys. Why is this happening?  
    • It happened on a snowy mountain in the overworld. It wasn't actually a crash, the game didn't close itself or something, it was more like when you are lagging online, and mobs are standing still, you cannot break blocks, things like that. Hope you'll find a solution Madz.
    • I am trying to add the mod "Create Questing" to the modpack SkyMachina but it just crashes. My log : https://pastebin.com/rq2jpph4   Please help, create is hard
