Chrome dino

Re-create Chrome Dino game using Canvas and TypeScript.

How to use it

Specify a node as root node to contain the canvas, e.g., #main-frame-error. Import Runner class and then instantiate it with static getInstance() method. Remember to remove the listeners after destroyed by invoking stopListening() method.

import Runner from "@/game/Runner"

export default function App() {
  useEffect(() => {
    const runner = Runner.getInstance("#main-frame-error")

    return () => {
      console.log("---Component Destroyed----")
      runner.stopListening()
    }
  }, [])

  return (<div id="main-frame-error"></>)
}

The game uses requestAnimateFrame() to boost drawing and make it move. Flag updatePending prevents duplicated registration of requestAnimateFrame().

class Runner {
  // member properties

  update() {
    this.updatePending = false
    // Perform all the drawing tasks

    // Schedule next frame drawing
    this.scheduleNextUpdate()
  }

  scheduleNextUpdate() {
    if (!this.updatePending) {
      this.updatePending = true
      // Register callback for the next available frame time to draw the next frame
      this.raqId = requestAnimationFrame(this.update.bind(this))
    }
  }
}
