Sketchbook 04 Game

Sketchbook 04 is a browser-based 3D physics playground and driving sandbox built using Three.js and Cannon.js. Unlike objective-driven games, this sandbox offers players an open environment to run, sprint, jump, and test a variety of drivable vehicles across custom-built stunt tracks. From sports cars and airplanes to helicopters, the simulation focuses on realistic suspension, momentum, and collision physics that react dynamically to ramps, loops, and obstacles.

Players start as a third-person character who can freely explore the terrain on foot before walking up to any vehicle to take control. Whether you want to perform drift stunts in a car, fly high above the grid in a jet, or simply crash into barriers to watch the physics engine react, Sketchbook 04 provides a seamless, bite-sized simulation sandbox that runs entirely in your browser with no downloads or installations required.

Controls

• Move / Steer: Use the WASD keys or Arrow keys to walk or drive.
• Jump: Press the Spacebar when on foot.
• Sprint / Boost: Hold the Shift key to run faster or accelerate vehicles.
• Enter/Exit Vehicle (Driver): Press the F key when standing next to a vehicle.
• Enter/Exit Vehicle (Passenger): Press the G key when standing next to a vehicle.
• Change Camera View: Press the C key to toggle perspective.
• Reset Position: Press the R key to respawn.

Tips and Tricks

• Master Vehicle Transitions: You are not locked into one vehicle. Simply pull up next to another car or aircraft, press F to step out of your current ride, walk to the next one, and press F again to drive.
• Experiment with Physics Ramps: The playground is filled with slopes, curves, and loops designed for stunt driving. Test different vehicles at varying speeds to see how weight, suspension, and momentum affect their flight and landing.
• Use Shift for Extra Speed: Whether you need to make a long jump over a gap or climb a steep incline, holding the Shift key activates a sprint/boost function for both characters and vehicles.
• Recover Instantly: If you crash, flip your car upside down, or fly off the map boundaries, press the R key to quickly respawn at the main starting zone.

This sandbox is ideal for players who love physics-based experiments, stunt driving, and casual open-world exploration. Open the game in your web browser, pick a vehicle, and start exploring the playground.
