Sending command to server from client

[sheepie20]

I have:

Minecraft.getInstance().player.sendChatMessage(command);

but im getting an error saying: Cannot resolve method 'sendChatMessage' in 'LocalPlayer':49

Now, I know what this error means, but I have no clue how to fix it. I am knew to java and forge modding.

I was thinking maybe it was an import issue? here are all my imports:
 

import net.minecraft.client.Minecraft;
import net.minecraftforge.common.MinecraftForge;
import net.minecraftforge.event.entity.player.PlayerEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.client.event.ClientChatEvent;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import java.util.Timer;
import java.util.TimerTask;

 

 

Does anybody know the solution?

you cannot sent chat message to server coze you cannot display messages in the server side
thats a client only thing

if you wanna make something happend server side from a client side trigger then
