Help!
I want to add 1 point to script A from script B but an error pops up(refer to title).
I don’t know what’s wrong with it.

!!!
movto2tama is the name of the script B.

Script A:

public var pluspoints : movto2tama;

    function Update()
    {
    	pluspoints.APoint();
    }

Script B:

private var points : int = 0;

function APoint()
{
	points = points + 1;
	print(points);
}

Thanks!

Likely ‘movtotama’ has not be assigned. You an drag the object that contains Script B onto the movto2tama variable in the inspector to do a link. Or you could setup the variable in Start(). Something like:

Start()
{
    movto2tama = GameObject.Find("NameOfGameObjectContainingScriptB");
}
