我正在尝试做一个游戏,我存储高分。什么是MyGameProgress类?
的“实现登录Android上的”链接:
https://developers.google.com/games/services/training/signin#signing_the_player_in_at_startup
表示使用MyGameProgress类保存了比分,成就等。 不过,我得到一个“无法解析符号MyGameProgress“当我尝试声明一个变量为MyGameProgress (例如MyGameProgress mGameProgress = new MyGameProgress())
任何人都有线索?
下面是我MainActivity.java文件:
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Gravity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.games.Games;
import com.google.example.games.basegameutils.BaseGameUtils;
public class MainActivity extends ActionBarActivity {
int Score = 0;
GoogleApiClient mGoogleApiClient;
MyGameProgress mGameProgress = new MyGameProgress();
private static int RC_SIGN_IN = 9001;
private boolean mResolvingConnectionFailure = false;
private boolean mAutoStartSignInFlow = true;
private boolean mSignInClicked = false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if (mResolvingConnectionFailure) {
// Already resolving
return;
}
// If the sign in button was clicked or if auto sign-in is enabled,
// launch the sign-in flow
if (mSignInClicked || mAutoStartSignInFlow) {
mAutoStartSignInFlow = false;
mSignInClicked = false;
mResolvingConnectionFailure = true;
// Attempt to resolve the connection failure using BaseGameUtils.
// The R.string.signin_other_error value should reference a generic
// error string in your strings.xml file, such as "There was
// an issue with sign in, please try again later."
if (!BaseGameUtils.resolveConnectionFailure(this,
mGoogleApiClient, connectionResult,
RC_SIGN_IN, "R.string.signin_other_error")) {
mResolvingConnectionFailure = false;
}
}
// Put code here to display the sign-in button
}
public void increaseScore(View view) {
Score = Score + 1;
TextView ScoreTextV = (TextView)findViewById(R.id.textView);
ScoreTextV.setText(Integer.toString(Score));
};
public void FinishGame(View view) {
//Games.Leaderboards.submitScore(getApiClient(),
// getString(R.string.leaderboard_high_score), Score);
// when user finishes level:
mGameProgress.addScore(userScore);
mGameProgress.addAchievement(fooAchievement);
mGameProgress.addAchievement(barAchievement);
if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
mGameProgress.save(mGoogleApiClient);
}
}
}
在我的build.gradle(module.app)我已经在依赖这包括:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile project(':BaseGameUtils')
compile 'com.android.support:appcompat-v7:21.0.3'
//compile 'com.google.android.gms:play-services-games:6.5.87'
compile 'com.google.android.gms:play-services:6.5.+'
在我的AndroidManifest.xml中包括:
<meta-data android:name="com.google.android.gms.games.APP_ID"
android:value="@string/app_id" />
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
我还进口了BaseGameUtils模块。
为了方便起见,这里是从我上面提供的“实现登录Android上的”链接的代码片段:
MyGameProgress mGameProgress = ....;
// when user finishes level:
mGameProgress.addScore(userScore);
mGameProgress.addAchievement(fooAchievement);
mGameProgress.addAchievement(barAchievement);
if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
mGameProgress.save(mGoogleApiClient);
}
@Override
protected void onConnected() {
// sign in successful, so save progress if we have any.
if (mGameProgress != null) {
mGameProgress.save(mGoogleApiClient);
}
// ...
}
,如果我需要创建MyGameProgress类我自己,我不知道如何创建'保存'方法,以便将高分存入游戏服务云。
我还看到了一些关于'快照'来保存游戏进度。你认为这是一个更好的方式吗?我应该这样研究吗?
您是否将适当的库添加到您的项目并导入正确的类? – JonasCz 2015-03-13 18:48:35
感谢您的回应。我刚添加了关于我添加到我的build.gradle和AndroidManifest文件的信息。希望这可以帮助你更好地了解可能的错误。 – 2015-03-13 21:24:58
我导入了BaseGameUtils模块。 – 2015-03-13 21:28:43
