Player can't build #c canbuild

Hi,

i want to deny admins to build.
But now nobody can build.

Code:

        bool CanBuild(Planner plan)
        {
            BasePlayer player = plan.GetOwnerPlayer();
            if (player.IsAdmin())
            {
                SendReply(player, "Buildung not allowd!");
                return false;
            }
            else
            {
                return true;
            }
        }

Is this the right way?
Info: I don't want to use the Oxide permission system

 

The code compile successfully. but everybody get the info Building not allowd. I'm wondering because it checks if the player is an admin...
[DOUBLEPOST=1475757708][/DOUBLEPOST]Ok only admins get the message with building not allowd. All other players didnt get the message but they cant build too. CanBuild is a bool and i think it must work with return true?!

 

Code:

object CanBuild(Planner plan, Construction prefab)
{
    if (plan == null || plan.GetOwnerPlayer() == null)
        return null;
    if (plan.GetOwnerPlayer().IsAdmin())
    {
        SendReply(plan.GetOwnerPlayer(), "You are not allowed to build!");
        return false;
    }
    return null;
}
