By focusing on the length and width differences, you can optimize checks by only comparing impacted axes, significantly reducing computation time.<\/li>\n<li><strong>Aspect Ratio Adjustments:<\/strong> Analyze the ratio between the length and width to optimize hitbox calculations. More significant differences in length-to-width ratios can alter how and when collisions occur, allowing you to tweak detection thresholds.<\/li>\n<li><strong>Spatial Partitioning:<\/strong> Implement spatial partition techniques like quad-trees or grid-based systems that factor in object dimensions.
