omg I totally forgot I programmed in Gamemaker

lol I program in unity now

I need help with this game I'm making in game maker,its a pong remake but the ball keeps going in the same direction. This is the code:

randomnum = irandom_range(1,30)
if (randomnum > 30) {
move_towards_point(obj_player,obj_player,3.0);
}

if (randomnum < 30) {
move_towards_point(obj_enemy,obj_enemy,3.0);
}

Its not even going towards a character its just going in the corner please help
