I'm working on a simple plugin that mimics the default hostile warning in rust and could use a little help. The code I have right now will send a player a message when hostile state is changed. Things I need to figure out are how to only print this once and not on every hostile update, and I don't know how to call/draw the warning symbol in the top right corner. I would also like to make the warning last the duration of the hostile timer but am unsure how I would go about that.

Here's what I got so far:

using Facepunch;
using Newtonsoft.Json;
using Newtonsoft.Json.Converters;
using Newtonsoft.Json.Linq;
using Oxide.Core;
using Oxide.Core.Configuration;
using Oxide.Core.Plugins;
using Oxide.Game.Rust.Cui;
using Rust;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using UnityEngine;

namespace Oxide.Plugins
{
    [Info("HostileWarn", "Savage", "0.0.4")]
    [Description("Hostile Chat Warning.")]
    public class HostileWarn : RustPlugin
    {

        private void OnEntityMarkHostile(BasePlayer player, float duration)
        {
            if (player.IsValid() == true || player.IsHostile() == true)
            {
                SendMessage(player, "You Are Marked <color=red>Hostile</color>!");
                return;
            }

        
        }


        void SendMessage(BasePlayer player, string msg, params object[] args)
        {
            {
                PrintToChat(player, msg, args);
                return;
            }
        
        
        }



    }
}​

1 things I'll like to note.

• OnEntityMarkHostilereturn type is an (object), not a void. Thus, you could return null to execute the hook normally, or anything other than null to prevent execution. (Most just return booleans to prevent executions)

Things I need to figure out are how to only print this once and not on every hostile update

It can be done this way

// This Hook is called before BasePlayer is marked hostile. So you want to your instructions inverted.
public object OnEntityMarkHostile(BasePlayer player, float duration)
{
    if(player.IsValid() && !player.IsHostile()) {
        // send message to player they've been marked hostile.
        SendMessage(player, "You Are Marked <color=red>Hostile</color>!");
    }else {
        // you can increase the player hostility timer. but lets make sure this wasn't their first time being hostile..
        if((int) player.State.unHostileTimestamp != 0) {
            // you can add/decrease timestamp here. (the highest timestamp or duration will be set as true timestamp)
            player.State.unHostileTimestamp += duration;
        }
    }
    return null;
}

I don't know how to call/draw the warning symbol in the top right corner

This can be called to mark on BasePlayer to make them hostile. 60f = 1minute in seconds. But if they're already hostile you can just increase the player unHostileTimestamp 

public override void MarkHostileFor(float duration = 60f)
{
	if (Interface.CallHook("OnEntityMarkHostile", this, duration) != null)
		return;
	double currentTimestamp = TimeEx.currentTimestamp;
	double val = currentTimestamp + (double)duration;
	this.State.unHostileTimestamp = Math.Max(this.State.unHostileTimestamp, val);
	this.DirtyPlayerState();
	double num = Math.Max(this.State.unHostileTimestamp - currentTimestamp, 0.0);
	base.ClientRPCPlayer<float>(null, this, "SetHostileLength", (float)num);
}

I would also like to make the warning last the duration of the hostile timer but am unsure how I would go about that.

Not 100% sure what you mean by this?
