Dr Driving Source Code [patched] -

// Simplified from reverse-engineered behavior public class PlayerCar float speed = 0; float maxSpeed = 12.0f; float turnAngle = 0; float turnSpeed = 2.5f; void update(float throttle, float steering) // Acceleration if (throttle > 0) speed += 0.2f; if (speed > maxSpeed) speed = maxSpeed; else speed *= 0.98f; // friction // Steering: Only effective when moving if (Math.abs(speed) > 0.5f) turnAngle += steering * turnSpeed * (speed / maxSpeed); // Update position based on angle & speed x += Math.sin(turnAngle) * speed; y -= Math.cos(turnAngle) * speed;

Original DR Driving likely used Axis-Aligned Bounding Boxes (AABB) for performance. A decompiled version of the source code would show something like: dr driving source code

Not only will you avoid legal trouble, but you will also create something unique—perhaps even better than the original. The next time you queue up at a red light in DR Driving, remember: each beep of the horn and screech of the tires is just conditional statements and velocity vectors working in harmony. And that harmony is something no source code repository can truly own. Have you built a clone or modded the original DR Driving? Share your experience in the comments below.
