The video is a coding challenge hosted by The Coding Train, where the host, Coding Train, attempts to program a popular game, Snake, on an Apple II Plus computer using AppleSoft Basic. The host starts the video by expressing their speculation about the viewer's timeline, jokingly guessing it's 40 years into the future.
The host then begins to demonstrate how to program in Basic, starting with basic commands like "Print", "List", and "Run". They also discuss how to create variables, use the "GoTo" command to loop the program, and how to handle keyboard input using memory addresses.
Next, they introduce the concept of arrays and how to use them to store the coordinates of the snake's body. They also create a subroutine to initialize the food's position randomly on the screen.
The host then introduces a new subroutine to update the snake's position based on keyboard input. They also add a feature to make the snake grow when it eats the food.
Finally, they add a feature to slow down the game's speed by adding a delay loop, and they handle the error when the snake hits the edge of the screen. They also add an array to store the snake's body, and allow the snake to grow when it eats the food. They also add a feature for the snake to die when it hits the wall or itself.
Throughout the video, the host frequently pauses to explain their thought process, share their excitement, and sing songs to keep viewers entertained. They also encourage viewers to leave comments expressing their interest in more Apple II videos.
1. The video is presented by a host who is attempting to program their most popular coding challenge ever on an Apple II Plus computer in Apple Basic.
2. The host is using a manual for reference and is showing viewers how to program in Basic, starting with a simple "Hello, world!" program.
3. The host is using commands such as "Print", "GoTo", and "List" to control the program's flow and display its output.
4. The host is attempting to create a Snake game, starting by printing characters to specific locations on the screen and animating them.
5. The host is using the commands "HTab" and "VTab" for horizontal and vertical positioning, and the command "Print" to place a character at a specific location.
6. The host is creating a subroutine to handle keyboard interaction, and is using the "Peek" command to read the computer's memory directly to determine which key was pressed last on the keyboard.
7. The host is using an "If" statement to check the value of the key pressed and increment the value of "x" or "y" accordingly.
8. The host is using a "For" loop to slow down the animation of the Snake game.
9. The host is adding an array to the program to create a series of "x" and "y" coordinates for the snake, and is using the "Dim" command to create a fixed array.
10. The host is creating a subroutine to initialize the food for the Snake game and is using the "RND" command to generate a random number for the food's position.
11. The host is using a "GoSub" command to call the subroutine for initializing the food.
12. The host is creating another subroutine to print the Snake at its most recent position and is using a "For" loop to iterate through the positions in the array.
13. The host is checking if the Snake has eaten the food by comparing the most recent spot for the Snake with the food's position, and if they match, the host is calling another subroutine to increase the length of the Snake.
