I want to perform scale animation on a text button using Tween Engine. I have used the same code for sprites and fonts with their respective Accessors. But for only TextButton, code is not working. Here is the code :
private void initLevelUpAnimation() {
Log.d("Runnable", "animation method called");
Skin skin = new Skin(); //empty constructor causes it not to load yet.
skin.add("level_new", levelUpBG);
levelupButtonStyle = new TextButton.TextButtonStyle();
levelupButtonStyle.font = game.levelUpFont;
levelupButtonStyle.up = skin.getDrawable("level_new");
levelupButtonStyle.down = skin.getDrawable("level_new");
levelupButtonStyle.over = skin.getDrawable("level_new");
levelupButtonStyle.disabled = skin.getDrawable("level_new");
levelupButton = new TextButton("LEVEL " + (baseLevel + 1) + "\n" + "KEEP GOING", levelupButtonStyle);
levelupButton.setSize(265, 180);
levelupButton.setPosition(gamePlayBG.getWidth() / 2 - levelupButton.getWidth() / 2,
gamePlayBG.getHeight() / 2 - levelupButton.getHeight() / 2);
Log.d("TWEEN", "Read to animate: ");
Tween.to(levelupButton, ButtonAccessor.SCALE_XY, 0.01f)
.ease(Elastic.INOUT)
.target(0.1f, 0.1f)
.setCallback(new TweenCallback() {
@Override
public void onEvent(int type, BaseTween<?> source) {
stopGameObjects = true;
Log.d("TWEEN", "First completed : 0.3");
Tween.to(levelupButton, ButtonAccessor.SCALE_XY, 0.7f)
.ease(Elastic.INOUT)
.target(1.1f, 1.1f)
.setCallback(new TweenCallback() {
@Override
public void onEvent(int type, BaseTween<?> source) {
Log.d("TWEEN", "Second completed : 0.3");
Tween.to(levelupButton, ButtonAccessor.SCALE_XY, 0.7f)
.ease(Elastic.INOUT)
.target(0.8f, 0.8f)
.setCallback(new TweenCallback() {
@Override
public void onEvent(int type, BaseTween<?> source) {
Log.d("TWEEN", "Third completed : 0.3");
Tween.to(levelupButton, ButtonAccessor.SCALE_XY, 1.0f)
.ease(Elastic.OUT)
.target(1.3f, 1.3f)
.setCallback(new TweenCallback() {
@Override
public void onEvent(int type, BaseTween<?> source) {
Log.d("TWEEN", "Fourth completed : 0.7");
Tween.to(levelupButton, ButtonAccessor.ROTATION, 1.0f)
.ease(Elastic.OUT)
.target(1.0f, 1.0f)
.setCallback(new TweenCallback() {
@Override
public void onEvent(int type, BaseTween<?> source) {
Log.d("TWEEN", "Fifth completed : 1.0");
stopGameObjects = false;
updateScoreTime();
}
})
.start(game.tweenManager);
}
})
.start(game.tweenManager);
}
})
.start(game.tweenManager);
}
})
.start(game.tweenManager);
}
})
.start(game.tweenManager);
}
Following is my ButtonAccessor :
public class ButtonAccessor implements TweenAccessor<TextButton> {
public static final int ALPHA = 0;
public static final int POS_XY = 1;
public static final int CPOS_XY = 2;
public static final int SCALE_XY = 3;
public static final int ROTATION = 4;
public static final int OPACITY = 5;
public static final int TINT = 6;
@Override
public int getValues(TextButton target, int tweenType, float[] returnValues) {
switch (tweenType) {
case ALPHA:
returnValues[0] = target.getColor().a;
return 1;
case SCALE_XY:
returnValues[0] = target.getScaleX();
returnValues[1] = target.getScaleY();
return 2;
case OPACITY:
returnValues[0] = target.getColor().a;
return 1;
case TINT:
returnValues[0] = target.getColor().r;
returnValues[1] = target.getColor().g;
returnValues[2] = target.getColor().b;
return 3;
default:
assert false;
return -1;
}
}
@Override
public void setValues(TextButton target, int tweenType, float[] newValues) {
switch (tweenType) {
case ALPHA:
target.setColor(target.getColor().r, target.getColor().g, target.getColor().b, newValues[0]);
break;
case SCALE_XY:
target.setScale(newValues[0], newValues[1]);
break;
case OPACITY:
Color c = target.getColor();
c.set(c.r, c.g, c.b, newValues[0]);
target.setColor(c);
break;
case TINT:
c = target.getColor();
c.set(newValues[0], newValues[1], newValues[2], c.a);
target.setColor(c);
break;
default:
assert false;
}
}
}
In render method :
game.batch.setProjectionMatrix(camera2.combined);
levelupButton.draw(game.batch, 1);
Button is drawn in screen but not animated. Can anyone tell me what I am doing wrong here ?
