Vehicles that wrap, collide, explode and restart

What it tests: State management: wrap-around movement, collision detection between moving objects, an explosion effect, then a clean full reset of the simulation loop.

Vehicle Collision & Restart Simulation **Goal:** Create a simulation demonstrating object movement, boundary wrapping, collision detection, simple visual effects, and state management for restarting the simulation loop. …

How to grade it

Several vehicles move and wrap at the edges; a collision triggers an explosion at the contact point; once the explosion ends, the whole simulation resets and starts again, repeatedly, without leftover particles or doubled loops.

Where models usually fail

The reset starts a second requestAnimationFrame loop each time, so it speeds up after every crash; collisions while wrapping across edges go unnoticed; the explosion never ends.

Running it

Made for local models via llama.cpp or KoboldCpp; the repo has a runner and side-by-side result pages.
