with Unity 3D Character
related files
- UnityActivity.java
3D Character is implemented in AI Human. Basically, it provides the same UI with AIPlayerDemo's and you can test it. This activity should use different than default process. (Check out the AndroidManifest.xml's activity process settings.)
You can change to other 3d models and it can speak with gestures.
Set up AndroidManifest.xml for UnityPlayerActivity As mentioned in project setup, UnityPlayerActivity needs AndroidManifest.xml setup. Please refer this link.
To use 3D character, the activity should extends UnityPlayerActivity and should implement IUnityPlayerCallback interface. In the 'UnityToAndroid(String param) method which is IUnityPlayerCallback, 'mAI3DPlayer.UnityToAndroid(param)' must be called.
public class UnityActivity extends UnityPlayerActivity implements IUnityPlayerCallback {
@Override
public void UnityToAndroid(String param) {
Log.d(TAG, "param:" + param);
mAI3DPlayer.UnityToAndroid(param);
}
}
Next, to setup UnityPlayerActivity, we need to set currentActivity, mUnityPlayer on ' onCreate(...)'. On 'createAI3DPlayer()', the mAI3DPlayer is instanciated and it is 3D character loadable Player which extends from UnityPlayer and we can make the character speak using it.
private AI3DPlayer mAI3DPlayer;
//call from unity. Should be static and don't change name
public static UnityActivity currentActivity;
@Override
protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
binding = UnityActivityBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
initSDKAuthInfoVars();
currentActivity = this;
String cmdLine = updateUnityCommandLineArguments(getIntent().getStringExtra("unity"));
getIntent().putExtra("unity", cmdLine);
createAI3DPlayer();
initThis();
}
private void createAI3DPlayer() {
mUnityPlayer = new AI3DPlayer(UnityActivity.this, binding.unityWrapper, UnityActivity.this);
mAI3DPlayer = (AI3DPlayer) mUnityPlayer;
mAI3DPlayer.requestFocus();
}
After receiving the usable AI list, we set up the UI. (Only 3D characters for this time). UnityPlayerActivity needs its own process. So, call AIModelInfoManager.generateToken() first to get the data correctly.
private void initThis() {
AIModelInfoManager.generateToken(this, appId, userkey, (aiError, resp) -> {
if (aiError == null) {
AIModelInfoManager.getAIList((aiError1, resp1) -> {
if (aiError1 == null) {
setUpUIWithAIPlayer();
} else {
Log.d(TAG, "initThis: getAIList error:" + aiError1);
Toast.makeText(UnityActivity.this, "getAIList error : " + aiError1.message, Toast.LENGTH_SHORT).show();
}
});
} else {
Log.d(TAG, "initThis: generateToken error:" + aiError);
Toast.makeText(UnityActivity.this, "Auth failed : " + aiError.message, Toast.LENGTH_SHORT).show();
}
});
}
changing current AI.
binding.aiSelectSpinner.setAdapter(new ArrayAdapter<>(UnityActivity.this,
android.R.layout.simple_spinner_dropdown_item, getAIDispNames()));
binding.aiSelectSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Log.d(TAG, "aiSelectSpinner onItemSelected: " + i);
curAIPlayerSettings = getAIPlayerSettings()[i];
// test
// customize character when loading ===========
// JSONObject customizeDefault = new JSONObject();
// JSONObject customizeInfo = new JSONObject();
// try {
// customizeDefault.put("hair", "short");
// customizeDefault.put("shoes", "black");
// customizeDefault.put("clothset", "suit_pants"); //set_name
// customizeInfo.put("customize_default", customizeDefault);
// } catch (JSONException e) {
// e.printStackTrace();
// }
// curAIPlayerSettings.customizeDefaultFor3D = customizeDefault;
// =========== add customize customize_default
mAI3DPlayer.init(curAIPlayerSettings, iAiPlayerCallback);
binding.scaleSeekbar.setProgress((int) ((curAIPlayerSettings.aiScale - 0.5) * 100));
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
The speak, pausePlay, resumePlay, stopSpeaking examples are below. The 'preload' method does not work for 3D character.
private void setUpUIWithAIPlayer() {
//...
binding.sendTextBtn.setOnClickListener(view -> {
if (selectedSpeech != null) {
if (selectedAIGesture != null) {
mAI3DPlayer.send(AIClipSetFactory.CreateClip(
selectedAIGesture.getName(), selectedSpeech, null));
} else {
mAI3DPlayer.send(AIClipSetFactory.CreateClip(
null, selectedSpeech, null));
}
} else {
if (selectedAIGesture != null) {
mAI3DPlayer.send(AIClipSetFactory.CreateClip(
selectedAIGesture.getName(), selectedSpeech, null));
} else {
//no gesture, no speech
Toast.makeText(UnityActivity.this, R.string.please_select_a_speech, Toast.LENGTH_SHORT).show();
}
}
});
binding.pauseBtn.setOnClickListener(View -> mAI3DPlayer.pausePlay());
binding.resumeBtn.setOnClickListener(View -> mAI3DPlayer.resumePlay());
binding.stopBtn.setOnClickListener(View -> mAI3DPlayer.stopSpeaking());
binding.multiSendBtn.setOnClickListener(View -> {
if (sampleText != null && sampleText.size() > 2) {
mAI3DPlayer.send(new String[]{sampleText.get(1), sampleText.get(2)});
} else {
Toast.makeText(this, "Speeches not ready", Toast.LENGTH_SHORT).show();
}
}
);
}
