9.1.7 Checkerboard V2 Codehs !free! Info

Ensure you are multiplying by SQUARE_SIZE and not adding it. Multiplication ensures perfect mathematical alignment on the canvas grid without leaving 1-pixel white lines between blocks. If you want to customize your board further, let me know:

Think of the board as a grid. You need to iterate over each row, and within each row, over each column.

Top Row (Row 0): (0,0) sum=0 [Even], (0,1) sum=1 [Odd], (0,2) sum=2 [Even] 9.1.7 Checkerboard V2 Codehs

Master this, and you have unlocked a fundamental pattern used in game development, graphics programming, and algorithm design.

The Checkerboard V2 project offers significant educational value, particularly in the areas of:

# Get the dimensions from the user (or specific constants if the problem asks) width = int(input("What width? ")) height = int(input("What height? ")) Ensure you are multiplying by SQUARE_SIZE and not adding it

Adding to Screen: Don't forget to use the add() function inside the inner loop so every individual square is rendered to the canvas.

from the autograder, such as the "assignment statement" requirement?

Inside the inner loop, use an if-else statement combined with the modulo operator ( % 2 == 0 ) to determine if the current coordinate sum is even or odd. Conceptual Code Structure You need to iterate over each row, and

add(square);

The classic 8x8 checkerboard uses a simple alternating pattern. One way to represent this pattern is using 0s and 1s, which is a great way to generate the board numerically.

function drawSquare(x, y, color) var rect = new Rectangle(SQUARE_SIZE, SQUARE_SIZE); rect.setPosition(x, y); rect.setColor(color); add(rect); Use code with caution. Step 3: Build the Nested Loop Logic
