The controller includes an automatic obstacle avoidance system that adjusts character movement based on the environment, while ensuring the player still feels in control.

Here’s how it works: The controller calculates an approximate stopping position based on the current velocity. If an obstacle is detected along the path, obstacle avoidance is activated. The system performs successive raycasts around the obstacle to find a clear path, and once found, the player's input is temporarily adjusted to steer the character around the obstacle.

The obstacle avoidance system is highly customizable, allowing developers to tweak settings to balance between precise player control and effective obstacle evasion, ensuring that players can smoothly navigate the environment without unwanted collisions.

The controller provides precise control over acceleration and deceleration through customizable easing functions, which define how the character’s speed changes over time during both phases.

To determine whether the character is accelerating or decelerating in 2D space, I calculate whether the velocity is moving closer to or farther from the origin.

Two distinct easing functions—one for acceleration and one for deceleration—govern the character's speed. Based on the character's current progress, these functions return the appropriate speed for that moment. By using the inverse of the easing functions, I can calculate this progress: inputting the current speed reveals how far the character has advanced along the acceleration or deceleration curve.

The character can automatically avoid obstacles based on the surface angle, distance, and position of the obstacle. This allows the character to smoothly pass between objects or slide along walls, ensuring smooth and intuitive controls.
