I am trying to make a game with a python library called 'Pygame' (v1.9.2) and I have made a character for the player. This character is supposed to "shoot" "bullets" or "spells" to the point of mouse_pos and what I need help with is that the "bullet" has a constant speed assigned to 1 self.speed = 1, if I try to increase the speed it will cause a flickering effect when the bullet reaches mouse_pos because self.pos will either be higher or lower than mouse_pos.
How can I make this bullet go quickly & smooth like a bullet and still get to the exact point where mouse_pos is set?
Example with self.speed = 1
Example with self.speed = 2

if self.idx >= len(self.effects):
self.kill()
