how to make the movement humanized

[isv]

this code makes the mouse move using mouse_event for certain angles, but the movement is very robotic, I would like to make the movement humanized, how can I do that?

weapons = [
        {
            "name":"XSW",
            "rpm":600,
            "magazine": 30,
            "img_name":"t_ak.png",
            "img": None,
            "x":1,
            "y":1,
            "pattern":[ (0,0),(0,28),(1,38),(3,47),(8,57),
                        (16,57),(13,53),(0,33),(-24,24),(-38,12),
                        (-34,6),(-25,10),(-18,4),(-18,2),(10,8),
                        (33,4),(41,10),(47,10),(42,0),(28,-5),
                        (8,1),(-4,5),(-1,9),(4,8),(5,6),
                        (-2,3),(-27,-2),(-51,-12),(-58,-14),(-56,-15) ]
        },
