NullReferenceException with my code

Code:

object OnXpEarn(BasePlayer player, float amount, string source)
        {
            if (HasPermission(player, "XP2"))
            {                //SendReply(player, source);
                return null;
            }
            else
{
return null;
}
        }

Code:

Object reference not set to an instance of an object

There is something wrong or I am doing something wrong?

 

Code:

object OnXpEarn(BasePlayer player, float amount, string source)
        {
                return null; 
        }

Same.

 

You are right. My bad.

But this

Code:

object OnXpEarn(BasePlayer player, float amount, string source)
        {
            if (player.IsAdmin())
            {
                SendReply(player, source);
                return null;
            }
            return null;
        }

Still NRE.

 

Sorry Wulf, what do you mean by null checks?

 

It's fine now. But I have another question.
Since I am making a personal plugin, I also want to boost xp, but for that I need to use the hook just in one plugin, so I have this problem:

Code:

object OnXpEarn(BasePlayer player, float amount, string source)
        {
            amount * 10f; //stolen from your plugin :P
// some other code that works fine
            return null;
        }

That does not work. I can't find what I am doing wrong.

 

Code:

amount = amount * 10f;
return amount;

Can't make it work.
Sorry Wulf, I'm giving you a headache.

 

You're right. Thanks Wulf. You're amazing.
