Cocos Creator
集成 Input SDK
Input SDK提供了一个统一的界面,让玩家在 Google Play Games For PC 上方便地找到游戏的鼠标和键盘绑定,从而提升玩家的游戏体验。
准备工作
如果你要在一个全新的 Android 构建上使用 Input SDK,只需要在构建面板上勾选 Input SDK 选项。
如果这个 Anrdoid 工程是之前构建的,就需要手动在 文件 native/engine/android/app/build.gradle
中添加下面的代码:
txt
dependencies {
implementation 'com.google.android.libraries.play.games:inputmapping:1.0.0-beta'
...
}
添加 InputMapProvider 实现
新建类文件 MyInputMapProvider.java
。
java
public class MyInputMapProvider implements InputMappingProvider {
public enum InputEventIds {
JUMP,
LEFT,
RIGHT,
USE,
SPECIAL_JUMP,
SPECIAL_DUCK,
CMB_MOVE,
CMB_DASH,
CMB_WAYPOINT
}
@Override
public InputMap onProvideInputMap() {
InputAction jumpInputAction = InputAction.create(
getString(R.string.key_jump),
InputEventIds.JUMP.ordinal(),
InputControls.create(
Collections.singletonList(KeyEvent.KEYCODE_SPACE),
Collections.emptyList()
)
);
InputAction leftAction = InputAction.create(
getString(R.string.key_Left),
InputEventIds.LEFT.ordinal(),
InputControls.create(
Collections.singletonList(KeyEvent.KEYCODE_DPAD_LEFT),
Collections.emptyList()
)
);
InputAction rightAction = InputAction.create(
getString(R.string.key_Right),
InputEventIds.RIGHT.ordinal(),
InputControls.create(
Collections.singletonList(KeyEvent.KEYCODE_DPAD_RIGHT),
Collections.emptyList()
)
);
InputAction cmbMove = InputAction.create(
getString(R.string.key_Move),
InputEventIds.CMB_MOVE.ordinal(),
InputControls.create(
Collections.emptyList(),
Collections.singletonList(InputControls.MOUSE_RIGHT_CLICK)
)
);
InputAction cmbDash = InputAction.create(
getString(R.string.key_Dash),
InputEventIds.CMB_DASH.ordinal(),
InputControls.create(
Arrays.asList(KeyEvent.KEYCODE_SHIFT_LEFT, KeyEvent.KEYCODE_SPACE),
Collections.emptyList()
)
);
InputAction cmbWaypoint = InputAction.create(
getString(R.string.key_Waypoint),
InputEventIds.CMB_WAYPOINT.ordinal(),
InputControls.create(
Collections.singletonList(KeyEvent.KEYCODE_SHIFT_LEFT),
Collections.singletonList(InputControls.MOUSE_RIGHT_CLICK)
)
);
InputGroup movementInputGroup = InputGroup.create(
getString(R.string.key_BasicMove),
Arrays.asList(jumpInputAction, leftAction, rightAction, cmbMove, cmbDash, cmbWaypoint)
);
return InputMap.create(
Arrays.asList(movementInputGroup),
MouseSettings.create(true, true)
);
}
}
添加按键的描述
在 res\values\strings.xml
中定义用于国际化的文本,以供前面步骤中使用。
xml
<resources>
...
<string name="key_jump">Jump</string>
<string name="key_Left">Left</string>
<string name="key_Right">Right</string>
<string name="key_Move">Move</string>
<string name="key_Dash">Dash</string>
<string name="key_Waypoint">Add Waypoint</string>
<string name="key_BasicMove">Basic Movement</string>
</resources>
修改 AppActivity
注册 InputMapping
AppActivity.java
位于 native\engine\android\app\src\main\cocos\game
,需做如下修改。
java
...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
InputMappingClient inputMappingClient = Input.getInputMappingClient(this);
inputMappingClient.setInputMappingProvider(new MyInputMapProvider());
}
...
@Override
protected void onDestroy() {
InputMappingClient inputMappingClient = Input.getInputMappingClient(this);
inputMappingClient.clearInputMappingProvider();
super.onDestroy();
...
}
测试效果
在 Google Play Games 提供的 HPE 模拟器中运行,通过 Shift + Tab 调出页面。
