So I have a method who starts a timer with a command and I wanna kill the same timer in another method. How would I do that? 
I know I am suppose to use replyTimer.Destory(); But since replyTimer is a local varible inside CommandReply I can't do it.

My code looks like this:

using Oxide.Core.Libraries.Covalence;
namespace Oxide.Plugins
{
[Info("test", "warmerspy", "0.1")]
public class test : CovalencePlugin
{




[Command("reply")]
void CommandReply(IPlayer player, string cmd, string[] args)
{

Puts("started reply");

Timer replyTimer = timer.Every(3f, () =>
{
player.Reply("Hey there player!");
});


}

[Command("stopreply")]
void CommandStopReply(IPlayer player, string cmd, string[] args)
{

//I wanna kill the timer here

}





}
}

Hey!
Declare the timer variable outside of the method

        Timer t;
        void MethodInitTimer()
        {
            t = timer.Every(1f, () => { });
        }
        void MethodDestroyTimer()
        {
            timer.Destroy(ref t);
        }

It worked thanks.
