Mega Car

In order to optimize performance for large environments, I implemented several techniques to ensure smooth gameplay. I utilized Level of Detail (LOD) to reduce the polygon count of distant objects, ensuring that far-off objects are rendered with lower detail without compromising visual quality. Additionally, I configured Unity’s Occlusion Culling system to prevent the rendering of objects that are not visible to the player, which significantly reduced the CPU and GPU load. To further optimize, I compressed textures and applied object pooling to efficiently reuse elements like ramps and obstacles, minimizing the need for frequent instantiation and destruction.

For implementing realistic car physics, I used Wheel Colliders to simulate real-world car behavior, adjusting values like friction, suspension spring, and slip to make the movement feel natural. I also introduced custom traction control to prevent the cars from spinning out when accelerating on high-speed ramps. Adjusting gravity scaling allowed for thrilling jumps while maintaining control for safe landings after mid-air stunts. Torque-based acceleration was applied to enhance realism, ensuring that the cars responded more naturally rather than relying on instant velocity changes.

To address high-speed collisions, I utilized raycasting for more accurate collision detection, preventing objects from passing through obstacles during high-speed impacts. A custom impact system dynamically calculated crash intensity, triggering different effects such as dents, severe damage, or full destruction based on the impact force. I also employed Rigidbody Interpolation and Continuous Collision Detection to avoid the "tunneling" issue, ensuring that fast-moving objects wouldn’t pass through walls. As for level design, I incorporated progressive difficulty with increasingly complex ramps and obstacles, dynamic hazards like moving barriers and falling objects, and multiple paths offering secret routes for skilled players. To keep the game engaging, I added time-based challenges and rewards, while the monetization strategy included optional rewarded ads, non-intrusive banner ads, premium car unlocks, and an ad-free purchase option to maintain a balance between revenue generation and user experience.
