Player Tick Event on Serverside [Problem] [1.12]

Posted May 15, 20187 yr

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

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.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!

hi i'm new to this. where does "--enable-native-access=com.sun.jna" go?

Hold on, wait a minute. So are you saying that the server you are trying to run is crashing or failing to work properly? If this is the case, then it should have nothing to do with a warning message. Could you be a little more specific as to what's going on? Are you just annoyed that there are some warning messages being displayed? (I mean, if that's the case then I can totally understand.) Again, I notice that you use the word "attempted" when referring to launching the forge server. This gives me the impression that something is going much more wrongly than a warning.

i am playing on a linux mint distro, and am attempting to run a forge 1.20.1 server

this seems to be the relevant warning message:
