However, getting the "fixed" version—where the grid perfectly alternates colors without overlapping or skipping—can be tricky. The objective is to create an
Each square must be the width of the canvas divided by 8.
Make sure your setPosition uses col * SQUARE_SIZE for the X-coordinate and row * SQUARE_SIZE for the Y-coordinate. Swapping these can sometimes cause the grid to render incorrectly if your canvas isn't a perfect square. 3. Infinite Loops 916 checkerboard v1 codehs fixed
The most common mistake in "v1" is only checking if the column is even or odd. If you do that, every row will look identical, resulting in vertical stripes rather than a checkerboard. Use the sum of the row and column indices. If (row + col) is even , color it Red. If (row + col) is odd , color it Black. The Corrected Code (JavaScript/Karel Style)
grid of squares where the colors alternate between black and red (or other assigned colors), resembling a standard checkerboard. Key Technical Requirements: Swapping these can sometimes cause the grid to
Here is a clean, "fixed" implementation for the CodeHS environment: javascript
The "916 checkerboard v1 codehs fixed" solution relies entirely on the . Once you master the nested loop structure, you can apply this logic to more complex grid-based games like Minesweeper or Chess. If you do that, every row will look
The color must switch based on both the row and column index to create the staggered effect. The Logic Behind the Fix
Mastering the 916 Checkerboard v1: Solutions and Logic for CodeHS
You need an outer loop for rows and an inner loop for columns.
