Development Assistance sender not working

Whenever i type a line of code with sender in it, it turns red, for instance. I type sender.sendMessage("Test"); and sender is underlined in red.. and wont fix.. help?

 

@EthanB7272
Could you post the entire method?

 

Um.. Maybe "sender" doesn't exist...

 

I was trying to do sender.sendMessage("&l&cMniGame HG Help")

 

@EthanB7272 Well one, no ";". Second, please post full class so we can see the issues and help you correct them.

 

When adding color to messages, rather than using the "&" symbol, use "§" or "ChatColor."

Code:

sender.sendMessage(ChatColor.RED + ChatColor.BOLD + "Minigame HG Help");

If it's any help to you, the onCommand method should look something like this:

Code:

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args){
if(cmd.getName().equals("command")){
sender.sendMessage("Testing");
}
return true;
}

You can use this as a reference when creating your plugin if you'd like, although I'd recommend that you post your entire block of code so that people can give you more helpful information.

 

Ok i fixed it but now i get this error in console when i try to load it
