MassInertia

A 2D action game built with Blazor WebAssembly. Control a rocket-shaped spaceship connected to a massive sphere and navigate through space.

Play the Game

• Arrow Keys: Rotate the spaceship left/right
• Space Bar: Fire the engine for thrust
• Physics: The game features realistic air resistance, gravity effects, and a rigid connection between the spaceship and a massive sphere

Game Mechanics

The spaceship is connected to a massive sphere with a rigid connection. When you apply thrust, the force is split between:

• Force components parallel to the connection (affecting both objects based on their mass ratio)
• Force components perpendicular to the connection (affecting only the spaceship)

This creates interesting movement dynamics where the spaceship and sphere influence each other's motion.

Pages

• Game: The main game with full physics simulation
• Simple Game: A simplified version that uses direct JavaScript rendering without complex interop
• Debug Test: A test page for troubleshooting JavaScript interop issues

Troubleshooting JavaScript Interop Issues

If you encounter the "Could not find 'drawGame'" error:

1. Try the Simple Game version: This uses direct JavaScript eval calls which are more reliable
2. Check browser console: Look for JavaScript errors
3. Verify JavaScript files are loaded: Both game.js and game-interop.js should be loaded
4. Fallback mechanisms: The game includes multiple rendering fallbacks:
   • Primary: gameInterop.drawGame function
   • Secondary: drawTest function
   • Last resort: Direct JavaScript eval with simplified rendering

Technology

• Built with C# and Blazor WebAssembly
• Renders on HTML Canvas
• Runs entirely in the browser (no server-side logic required)
• Implements a realistic physics model including momentum, gravity, and air resistance
