PhysicsEditor is a powerful tool made by CodeAndWeb that helps game developers design collision shapes for 2D games. It saves developers from writing thousands of lines of messy math coordinates by hand.
The top features of PhysicsEditor that every game developer needs include: 1. Automatic Shape Tracer
Writing down the exact X and Y coordinates for a strange shape like a banana or a guitar takes hours. PhysicsEditor has an automated magic tracer. It looks at your game art, finds the transparent edges, and draws the collision lines for you in just one click. You can use a slider to change the settings until the shape fits perfectly. 2. Smart Convex Decomposition
Most 2D game physics engines (like Box2D) cannot handle “concave” shapes. A concave shape is any shape that caves inward, like a star or a crescent moon. PhysicsEditor fixes this by automatically cutting dented shapes into smaller pieces that the game engine can understand. You do not have to do any math or split the shapes yourself. 3. Visual Physics Parameter Tuning
Every game object needs different physical traits to act real. Instead of coding numbers and restarting your game constantly, PhysicsEditor lets you type values directly into a sidebar. You can visually adjust: Mass/Density: How heavy the object is. Friction: How easily the object slides across surfaces. Restitution: How bouncy the object is. 4. Detailed Fixtures and Collision Sensors
You can create multiple physics zones on a single game character. For example, you can give a monster a separate zone for its head, torso, and feet. This helps you code different damage rules for headshots. You can also turn shapes into invisible sensors. These sensors detect when things are close by without making them bounce away, which is perfect for trigger zones. 5. Custom Exporters for Any Game Engine Intro to PhysicsEditor
