So I'm basically trying to make this explosion push things outwards via physics impulse with this formula as the angle "angle(self.X, self.Y, ExplosionBox.X, ExplosionBox.Y"

However, it pushes the objects in a very strange direction. As you can see from the picture, there are 2 lines. The line between Point 1 and 2 is the angle that the objects are being thrown at, but I would rather have an angle like the other one. How can I go about this? Is there a way for me to get the coordinates for point 3?
