Angular4 自制打地鼠游戏
前端工程师新手一枚，之前一直做些小设计，以及静态页面的编写工作。刚刚接触 Angular 没有多久，四个月前对于 Javascript也只是会写 alert 之流，现在进步算是很大，下面是自制的打地鼠游戏，是可以升级关卡的哦，希望大神临幸，千万别拍砖。
最后的成品是这样的，这是第四关：
HTML:
Score: {{score.scoreTotal}}
Hit Rate: {{score.hitRate}}%
Time Left: {{time.timeLeft}}
-
[ngClass]="{ 'moleClicked': i == mole.clickedMole }">
Game Over!
Conguratulations! You passed all the barries!
