在我的Tile類中,我使用TextureAtlas's createSprite()
將sprites
分配給每個圖塊。現在從我的screenLauncher類中,當我點擊tile時,我想要更改Tile的精靈,即圖像。如何實現這一點?瓷磚類使用TweenEngine來動畫瓷磚。使用通用吐溫引擎動態更改Sprite
我的瓷磚類:
public class Tile {
private final float x, y;
public String title;
Sprite sprite;
private final Sprite interactiveIcon;
private final Sprite veil;
private final OrthographicCamera camera;
private final BitmapFont font;
private final TweenManager tweenManager;
private final MutableFloat textOpacity = new MutableFloat(1);
public Tile(float x, float y, float w, float h, String title, String spriteName, TextureAtlas atlas, TextureAtlas launcherAtlas, OrthographicCamera camera, BitmapFont font, TweenManager tweenManager) {
this.x = x;
this.y = y;
this.title = title;
this.camera = camera;
this.font = font;
this.tweenManager = tweenManager;
this.sprite = launcherAtlas.createSprite(spriteName);
this.interactiveIcon = atlas.createSprite("interactive");
this.veil = atlas.createSprite("white");
sprite.setSize(w, h);
sprite.setOrigin(w/2, h/2);
sprite.setPosition(x + camera.viewportWidth, y);
interactiveIcon.setSize(w/10, w/10 * interactiveIcon.getHeight()/interactiveIcon.getWidth());
interactiveIcon.setPosition(x+w - interactiveIcon.getWidth() - w/50, y+h - interactiveIcon.getHeight() - w/50);
interactiveIcon.setColor(1, 1, 1, 0);
veil.setSize(w, h);
veil.setOrigin(w/2, h/2);
veil.setPosition(x, y);
veil.setColor(1, 1, 1, 0);
}
public void draw(SpriteBatch batch) {
sprite.draw(batch);
float wrapW = (sprite.getWidth() - sprite.getWidth()/10) * Gdx.graphics.getWidth()/camera.viewportWidth;
font.setColor(1, 1, 1, textOpacity.floatValue());
font.drawWrapped(batch, title,
sprite.getX() + sprite.getWidth()/20,
sprite.getY() + sprite.getHeight()*19/20,
wrapW);
if (veil.getColor().a > 0.1f) veil.draw(batch);
}
public void enter(float delay) {
Timeline.createSequence()
.push(Tween.to(sprite, SpriteAccessor.POS_XY, 0.7f).target(x, y).ease(Cubic.INOUT))
.pushPause(0.1f)
.push(Tween.to(interactiveIcon, SpriteAccessor.OPACITY, 0.4f).target(1))
.delay(delay)
.start(tweenManager);
}
public boolean isOver(float x, float y) {
return sprite.getX() <= x && x <= sprite.getX() + sprite.getWidth()
&& sprite.getY() <= y && y <= sprite.getY() + sprite.getHeight();
}
public String getTitle()
{
return this.title;
}
}
我想知道,如果它使用通用吐溫引擎動態地改變精靈是可能的LibGdx。
