How it works
The AI uses forward simulation to decide when to jump or duck. Each frame, it clones the current game state and simulates the next 80 frames for three scenarios: keep running, jump now, or duck now. If running straight will collide with an obstacle, it picks whichever alternative keeps the dinosaur alive.
Tap Viz to watch the AI think. A cloud of simulated paths appears ahead of the dinosaur — blue for jumping, orange for ducking, dark for running. The thick line is the chosen path; fainter lines are alternatives the AI evaluated. A badge above the dino shows the current decision.
