}

function BrainTimer()
{
local int OffsetX;
local int OffsetY;

//make a random offset, some distance away
OffsetX = Rand(500)-Rand(500);
OffsetY = Rand(500)-Rand(500);

//some distance left or right and some distance in front or behind
MyTarget.X = Pawn.Location.X + OffsetX;
MyTarget.Y = Pawn.Location.Y + OffsetY;
//so it doesnt fly up n down
MyTarget.Z = Pawn.Location.Z;

GoToState('MoveAbout');

}
