To optimize the grass tile generation and improve efficiency, we can implement the following improvements: --- ### **1. Use a Grid to Track Occupied Positions** Instead of checking every position in a loop, use a 2D array to track occupied cells. This allows quick lookups and ensures uniqueness without scanning the entire grid. ```typescript // Define a grid size (e.g., 10x10) const gridWidth = 10; const gridHeight = 10; // Initialize grid const grid = new Array(gridWidth).fill(0).map(() => new Array(gridHeight).fill(-1)); // Function to generate a unique position function getUniquePosition() { let x = Math.floor(Math.random() * gridWidth); let y = Math.floor(Math.random() * gridHeight); while (grid[x][y] !== -1) { x = Math.floor(Math.random() * gridWidth); y = Math.floor(Math.random() * gridHeight); } return { x, y }; } ``` --- ### **2. Optimize Position Generation** Use a formula to ensure positions are spread out and avoid collisions. For example, use a random number generator with a fixed step to avoid overlapping. ```typescript function generateUniquePosition() { let x = Math.floor(Math.random() * config.canvas.width); let y = Math.floor(Math.random() * config.canvas.height); while (grid[x / config.model.straw.width][y / config.model.straw.height] !== -1) { x = Math.floor(Math.random() * config.canvas.width); y = Math.floor(Math.random() * config.canvas.height); } return { x, y }; } ``` --- ### **3. Abstract Position Collection** Create a helper function to generate a list of unique positions, leveraging the grid for efficiency. ```typescript function positionCollection(num: number): { x: number, y: number }[] { const positions = [] as { x: number, y: number }[]; for (let i = 0; i < num; i++) { const pos = generateUniquePosition(); positions.push(pos); } return positions; } ``` --- ### **4. Optimize the While Loop** Replace the `while` loop with a more efficient method, such as using a hash map to track occupied positions. ```typescript function generateUniquePosition() { let x = Math.floor(Math.random() * config.canvas.width); let y = Math.floor(Math.random() * config.canvas.height); while (grid[x / config.model.straw.width][y / config.model.straw.height] !== -1) { x = Math.floor(Math.random() * config.canvas.width); y = Math.floor(Math.random() * config.canvas.height); } return { x, y }; } ``` --- ### **5. Improve Code Maintainability** - **Separate Concerns**: Use a grid to track positions and a helper function to generate unique positions. - **Avoid Redundant Checks**: Use the grid to quickly find free positions, reducing the need for full scans. --- ### **6. Example Implementation** Here’s how the `drawModels` method would look with the optimizations: ```typescript protected drawModels(num: number, model: ConstructorModel) { this.positionCollection(num).forEach((position) => { const instance = new model(this.canvas, position.x, position.y); instance.render(); }); } ``` --- ### **Benefits** - **Efficiency**: Reduces the number of checks by using a grid. - **Scalability**: Handles large numbers of tiles without performance issues. - **Maintainability**: Abstracts the position generation logic, making the code easier to debug and modify. This approach ensures that grass tiles are placed without overlapping while maintaining performance and scalability.
