DR Driving feels good because of . Instead of full tire friction simulation, they likely used:
// Steering only when moving float turn = steer * turnSensitivity * Time.deltaTime * (currentSpeed / maxSpeed); rb.angularVelocity = -turn;
: Unlike high-fidelity sims, the code focuses on "Arcade" mechanics—prioritizing quick steering response and stable drifting over realistic weight transfer. Low-Poly Optimization
to allow players to control the car by turning a "virtual" steering wheel in the air using their hands, essentially writing a new "control layer" on top of the existing game. The AI Clone Wars
// Update position based on angle & speed x += Math.sin(turnAngle) * speed; y -= Math.cos(turnAngle) * speed;
- IDLE: Waiting at a traffic light.
- CRUISE: Moving at a constant speed along a defined path (spline).
- AVOID: Executing a "raycast" check to detect the player; applies brakes if distance < threshold.
- LANE_CHANGE: Shifting positions, utilizing a pathfinding node
