! The material code contains all the code I have written and has complete annotations for easy learning.

Game Rules

1-four lines of bricks are displayed on the screen.
2-click the screen to start the game
3-at the beginning of the game, the primary ball went up to the primary node
4-The impact of small balls and bricks can break bricks and rebound
5-the collision between the small ball and the top, right, and left of the screen will rebound
6-the collision between the small ball and the baffle will rebound
7-move your finger around to move the baffle plate
8-"the game ends when the player drops the ball from the bottom of the screen.

Development procedure

1-new project category
2-build a community
Obtain the interface objects and listen to screen events (the storyboard setting interface is disconnected)
3-"code implementation
Click the screen to let the ghost ball move (Game clock, refresh location)
Brick collision detection (hidden after collision)
Drag the baffle plate to change the direction of the slider (get the drag gesture speed and change the ball speed)
Determine the outcome and reset the game (the minimum value of y in the position of the ball is greater than the maximum value of y on the screen)
