Question

我无法阻挡他们已经通过的玩家路径。我让玩家留下了一条没有想过要经历的粘液。我使用了崇高的文字

我尝试通过将代码更改为此来解决此问题：

＆＃13;

// WASD keys to move The Snail
if (key == 119) {
  //Check that up isn’t a wall
  //Check that up isn’t off the screen
  if (player.y - 1 >= 0) {
    if (PS.data(player.x, player.y - 1) != "wall") {
      //If both are true, remove player from current position
      //If both are true, draw player in new position
      removePlayer(player.x, player.y);
      drawPlayer(player.x, player.y - 1);
      drawSlime(player.x, player.y);
    }
  }
}
if (key == 115) {
  //Check that down isn’t a wall
  //Check that down isn’t off the screen
  if (player.y + 1 < GRIDHEIGHT) {
    if (PS.data(player.x, player.y + 1) != "wall") {
      //If both are true, remove player from current position
      //If both are true, draw player in new position
      removePlayer(player.x, player.y);
      drawPlayer(player.x, player.y + 1);
      drawSlime(player.x, player.y);
    }
  }
}
if (key == 97) {
  //Check that left isn’t a wall
  //Check that left isn’t off the screen
  if (player.x - 1 >= 0) {
    if (PS.data(player.x - 1, player.y) != "wall") {
      //If both are true, remove player from current position
      //If both are true, draw player in new position
      removePlayer(player.x, player.y);
      drawPlayer(player.x - 1, player.y);
      drawSlime(player.x, player.y);

    }
  }
}
if (key == 100) {
  //Check that right isn’t a wall
  //Check that right isn’t off the screen
  if (player.x + 1 < GRIDWIDTH) {
    if (PS.data(player.x + 1, player.y) != "wall") {
      //If both are true, remove player from current position
      //If both are true, draw player in new position
      removePlayer(player.x, player.y);
      drawPlayer(player.x + 1, player.y);
      drawSlime(player.x, player.y);
    }
  }
}

虽然这有效，但我无法与游戏中的项目进行互动，

无法在Javascript中阻止播放器的路径
