I'm looking for a way to check if a player uses any sort of teleportation, since with this code, people can't "move" out of my borders, they can however, teleport. I was wondering if I can force survival on those who may try to teleport out of the borders.

 

Here's the code:

 

package com.troelsen.buildingarea;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.TickEvent.PlayerTickEvent;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.world.WorldSettings.GameType;

import java.awt.*;

public class EventHandlerCommon {

    @SubscribeEvent
    public void tickEvent(PlayerTickEvent event) {
       
        Rectangle rec1 = new Rectangle(-10, -10, 20, 20); // constructor er (x, z, width, height)
        Rectangle rec2 = new Rectangle(-15, -15, 30, 30);
        
        Point playerPos = new Point((int)event.player.posX, (int)event.player.posZ);
       
        // Hvis man er inden for den yderste rectangle, og uden for den inderste
        if (event.player.capabilities.isCreativeMode && rec2.contains(playerPos) && !rec1.contains(playerPos)) {
            event.player.setGameType(GameType.SURVIVAL);
        }
    }
}

 

Thanks in advance

There's no event fired for player teleportation.

 

You could attach an IExtendedEntityProperties implementation (or a Capability in 1.8.9+) to

EntityPlayer

that stores whether they were in the borders the previous tick.

 

If they were in the borders last tick but they're not this tick, set them to survival mode.

Thank you for the quick response!

 

I thought of checking for the last tick as well, and I also tried.

 

However player.lastTickPosX/Z doesn't seem to work as I thought it would

 

public class EventHandlerCommon {

    @SubscribeEvent
    public void tickEvent(PlayerTickEvent event) {
       
        Rectangle rec1 = new Rectangle(-10, -10, 20, 20); // constructor er (x, z, width, height)
        Rectangle rec2 = new Rectangle(-12, -12, 24, 24);
        
        Point playerPos = new Point((int)event.player.posX, (int)event.player.posZ);
        Point playerPose = new Point((int)event.player.lastTickPosX, (int)event.player.lastTickPosZ);
       
        // Hvis man er inden for den yderste rectangle, og uden for den inderste
        if (event.player.capabilities.isCreativeMode && rec2.contains(playerPos) && !rec1.contains(playerPos)) {
            event.player.setGameType(GameType.SURVIVAL);
        } else if (rec2.contains(playerPose) && !rec1.contains(playerPose)) {
        	event.player.setGameType(GameType.SURVIVAL);
        }
    }
}

 

There's no errors in my code, it does however not change the gamemode once teleported

Try setting a breakpoint and stepping through the method in a debugger. Is the previous tick position accurate after teleporting? Is the current position accurate?

 

Something I just remembered: All subclasses of

TickEvent

are fired twice per tick of their corresponding system, once with

Phase.START

and once with

Phase.END

. Make sure you check the

Phase

to avoid running your code twice per tick.

Hai Choonster!

 

I got working by making an IExtendedEntityProperties as you told me to.

 

Thanks again for your help!
