Making the chrome dino game play itself using Javascript

function autoplay() {  setTimeout(function () {    myinstance = this.Runner.instance_;    myobstacles = myinstance.horizon.obstacles;    // if my tRex is ducking then    if (myinstance.tRex.ducking) {      // make my tRex to duck      myinstance.tRex.setDuck(true);    }    if (myinstance.crashed) {      //   When the game is over then      console.log("Game Over... Paste the code again to automate the game");      return;    }    if (myobstacles.length > 0) {      action = "JUMP";      obstacle_type = myobstacles[0]["typeConfig"]["type"];      // Defining which action to perform if it match the following cases      if (obstacle_type == "CACTUS_SMALL" || obstacle_type == "CACTUS_LARGE") {        action = "JUMP";        // i know its a hard name ( actually PTERODACTYL its the bird )      } else if (obstacle_type == "PTERODACTYL") {        if (myobstacles[0]["yPost"] == 75 || myobstacles[0]["yPost"] == 50)          action = "DUCK";      }      // Making the action work      if (myobstacles[0].xPos <= 100) {        console.log(myobstacles[0]);        // Perform the action        if (action == "JUMP") {          console.log("Jumping..
