How to achieve collision and rebound of multiple balls through JS

This article mainly introduces the native JS to realize the collision and rebound effect of multiple small balls, and analyzes the related numerical calculation, random number generation, event response and other operation skills of JavaScript to realize the small ball collision in the form of a complete example. Friends who need it can Refer to the following

example of this article describing the native JS to achieve the collision and rebound effect of multiple small balls. Share it with everyone for your reference, the details are as follows:

Implementation ideas:The movement of the ball is changed by changing the left and top values of the ball. The coordinates are (x, y) )When the x/y value is added to the maximum, that is, when it is added to the width or height of the parent, the x value or y value is reduced. Similarly, when the x value or y value is reduced to the minimum, the x value or y value is also reduced. In addition, the above ideas can realize the rebound of the ball when it hits the wall.

The collision between the ball and the ball needs to determine which direction the ball is being hit, so as to determine which direction the ball should move. , also change the coordinate value of the ball to realize the rebound of the ball

Implementation code:

Operation effect:

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
