Creating a Ping Pong Game in mBlock is a fun and interactive way for students to learn programming concepts like loops, conditionals, and events. Here's a step-by-step guide: Objective Students will create a basic ping-pong game where: 1. A ball moves across the screen. 2. Players control a paddle to bounce the ball. 3. The game ends if the ball misses the paddle. Step-by-Step Instructions 1. Setup the Stage Open mBlock and switch to the Sprite Tab . Choose or draw a simple backdrop (e.g., a solid background or a sports theme). 2. Add Sprites Ball : Click "Choose a Sprite" and select or draw a ball. Paddle : Add a new sprite, like a rectangle, to represent the paddle. 3. Code for the Ball 1. Initialize the Ball : o Add the following script to the Ball: plaintext Copy code When Green Flag clicke...
A number system defines a way to represent numbers. Computers use different number systems for processing and representation. The most common systems are Binary , Decimal , Octal , and Hexadecimal . 1. Binary Number System Base: 2 Digits Used: 0, 1 Example: 101121011_210112 How it Works: Each binary digit (bit) represents a power of 2. For example: 10112=(1×23)+(0×22)+(1×21)+(1×20)=11101011_2 = (1 \times 2^3) + (0 \times 2^2) + (1 \times 2^1) + (1 \times 2^0) = 11_{10}10112=(1×23)+(0×22)+(1×21)+(1×20)=1110 Use: Widely used in computers for internal data representation and processing. 2. Decimal Number System Base: 10 Digits Used: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Example: 25610256_{10}25610 How it Works: Each digit represents a power of 10. For example: 25610=(2×102)+(5×101)+(6×100)256_{10} = (2 \times 10^2) + (5 \times 10^1) + (6 \times 10^0)25610=(2×102)+(5×101)+(6×100) Use: The most commonly used num...
