Player Tick Event on Serverside [Problem] [1.12]

[#ÖCT]

Hey

I have a problem with the server compatiblility.

Both Sides starts, but I can`t connect to the server...

 

I used the common PlayerTickEvent

Spoiler

 

 

package oect.lwaltens.luckyblockoect.utils;

import java.util.Random;

import net.minecraft.block.Block;
import net.minecraft.block.state.IBlockState;
import net.minecraft.client.Minecraft;
import net.minecraft.entity.item.EntityFallingBlock;
import net.minecraft.entity.item.EntityItem;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Blocks;
import net.minecraft.init.Items;
import net.minecraft.item.ItemStack;
import net.minecraft.server.MinecraftServer;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.Mod.EventHandler;
import net.minecraftforge.fml.common.eventhandler.SubscribeEvent;
import net.minecraftforge.fml.common.gameevent.TickEvent;
import net.minecraftforge.fml.common.gameevent.TickEvent.ServerTickEvent;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;
import oect.lwaltens.luckyblockoect.registeries.LuckyBlockOect_Potions;

public class ServerEvents 
{

	@SubscribeEvent
	public void PotionFakeBlockAll(TickEvent.PlayerTickEvent event) 
	{
		Minecraft mc = Minecraft.getMinecraft();
		EntityPlayer player = event.player;
		World world = player.getEntityWorld();
		if(player.isPotionActive(LuckyBlockOect_Potions.fakeblockall)) 
		{
			if(!world.isRemote) 
			{
				BlockPos pos = player.getPosition();
				BlockPos pos1 = new BlockPos(pos.getX(), pos.getY()-1, pos.getZ());
				
				IBlockState state = world.getBlockState(pos1);
				
				
				if(state != null) 
				{
					EntityFallingBlock modelblock = new EntityFallingBlock(world, (int)player.posX+0.5, (int)player.posY, (int)player.posZ-0.5, state);
					world.spawnEntity(modelblock);
				}
				
				
			}
		}
	}
}

I register the EventHandler, like this in my preInit:

MinecraftForge.EVENT_BUS.register(new ServerEvents());

 

I think i must to change something only for server/client side, but what??

 

Thank you for help!

You can't reference client-side only code like that from your common code, use proxies. Or delete that line entirely since you do nothing with the mc local anyway.

What do you mean by "can't connect"? Is there an error in your log?

Ahhhhhh, that was from the old code.

I don`t need them and when I removed it all works perfectly.

Thank you!
