大家好,又见面了,我是你们的朋友全栈君。
一,游戏介绍
这是一个在线编写JS代码的游戏:http://play.elevatorsaga.com/
显示界面:
其中的doc是肯定要看的。
操作界面:
初始代码:
代码语言:javascript复制{
init: function(elevators, floors) {
var elevator = elevators[0]; // Let's use the first elevator
// Whenever the elevator is idle (has no more queued destinations) ...
elevator.on("idle", function() {
// let's go to all the floors (or did we forget one?)
elevator.goToFloor(0);
elevator.goToFloor(1);
});
},
update: function(dt, elevators, floors) {
// We normally don't need to do anything here
}
}
二,闯关
第1关
初始代码有提示:let’s go to all the floors (or did we forget one?)
本关代码:
代码语言:javascript复制{
init: function(elevators, floors) {
var elevator = elevators[0]; // Let's use the first elevator
// Whenever the elevator is idle (has no more queued destinations) ...
elevator.on("idle", function() {
// let's go to all the floors (or did we forget one?)
elevator.goToFloor(0);
elevator.goToFloor(1);
elevator.goToFloor(2);
});
},
update: function(dt, elevators, floors) {
// We normally don't need to do anything here
}
}
第2关
代码语言:javascript复制{
init: function(elevators, floors) {
var elevator = elevators[0]; // Let's use the first elevator
var floor = floors[0];
// Whenever the elevator is idle (has no more queued destinations) ...
elevator.on("idle", function() {
//elevator.goToFloor(0);
});
elevator.on("floor_button_pressed", function(floorNum) {
elevator.destinationQueue.push(floorNum);
elevator.checkDestinationQueue();
})
floor.on("up_button_pressed", function() {
elevator.destinationQueue.push(floor.floorNum());
elevator.checkDestinationQueue();
})
floor.on("down_button_pressed", function() {
elevator.destinationQueue.push(floor.floorNum());
elevator.checkDestinationQueue();
})
},
update: function(dt, elevators, floors) {
// We normally don't need to do anything here
var elevator = elevators[0]; // Let's use the first elevator
for(var i=1;i<=4;i ){
if(elevator.destinationQueue.indexOf(i)>-1){
elevator.goToFloor(i);
}
}
for(var i=4;i>0;i--){
if(elevator.destinationQueue.indexOf(i)>-1){
elevator.goToFloor(i);
}
}
}
}
第2关我居然都没能通过,主要是JS不熟,加上API没太看懂。。。
