我在run()
方法中有一個簡單的遊戲循環。該班正在執行Runnable
。我只是想創建一些簡單的時間碼來跟蹤玩家一直在玩的時間。假設我想在兩分鐘後結束遊戲。run()方法中的時間
我不知道我這樣做是正確的,因爲我在屏幕上的時間不是秒,它的時間格式是long
,比如1370502588.我做錯了什麼?
這裏是run()
方法中的代碼的一部分:
// Game loop ---------------------------------------
@Override
public void run() {
// TODO Auto-generated method stub
// Time
long startGameTime = 0;
long milliSeconds;
int seconds;
while (gameRunning) {
if (!surfaceHolder.getSurface().isValid())
continue;
try {
milliSeconds = System.currentTimeMillis() - startGameTime;
seconds = (int) (milliSeconds/1000);
if (seconds > 120)
// Game over
canvas = surfaceHolder.lockCanvas();
...

你可以發佈你的logcat嗎?你是否從timertask更新ui? – Raghunandan
