//  generateWorld Function Reference:
// pixel: The generateWorld function is used in onPlace(pixel), the reason of including pixel is to delete it.
// layers: An array of layer objects like this:
//         [{element: "yourElement", chance: 0.5}, {...}, ...]
//         Each layer is placed one row above the previous.
//         'chance' must be between 0 and 1 — higher means more likely to generate.
// startX / endX: Horizontal range to generate across. Default is -500 to 500.
// baseY: Vertical starting point for the bottom layer. Default is 82 (bottom of medium canvas).
//
//  Tip: To insert empty space between layers, use an empty object: {}
// Example: [layer1, {}, layer3] will skip one row between layer1 and layer3.
// Fact: The index 0 layer will be placed at the baseY, and the index 1 layer will be placed in baseY - 1, so when looking at the code, it looks upside down.
// Note: If someone is using tinier or bigger canvas size then this may not work as needed, you should make a case for each canvas size
