我正在尝试为我的场景中的某些演员重现精灵动画。除了阅读一本书之外,我还在观看有关如何使用“FlappyBird”游戏libgdx创建的分步教程。这并不是说我做同样的事情要么比视频中的人想要做的那样。
我试图制作像“水果粉碎”或“宝石迷阵”这样的游戏......就像那样。我创建了我的菜单和我的游戏(或者像教程一样的播放状态)。我也创建了一个表类(这个类扩展了Stage)来管理舞台的框(演员)。程序已经将盒子放在各自的位置并获得每个盒子的坐标,这样当你点击一个盒子时,游戏就知道它是哪个盒子。
现在......我想重现一些盒子的精灵动画......但我的桌子(或舞台)不播放动画。
My Box课程是这样的:
public class Box extends Actor {
private Tipo tipo;
private boolean activo;
private String clase;
private TextureRegion region;
private float elapsedTime;
private Animation<TextureRegion> animacion,selected, unselected;
private Rectangle area;
private float velocidadY,velocidadX;
private int minY,minX,maxY,maxX;
public Box(){
super();
velocidadX = 0;
velocidadY = 0;
minY = 0;
minX = 0;
maxY = 0;
maxX = 0;
elapsedTime = 0;
activo = false;
region = new TextureRegion();
area = new Rectangle();
asignarTipo();
}
//HERE I ASSIGN THE TYPE OF EACH BOX
public void asignarTipo(){
Random rand = new Random();
int t = rand.nextInt((4-1)+1)+1;;
switch (t){
case 1:
tipo = Tipo.cbV2;
clase = "V2";
unselected = new Animation(0.2f,cargarSprites("1B",".png",1));
selected = new Animation(0.2f,cargarSprites("1",".png",2),Animation.PlayMode.LOOP_PINGPONG);
setAnimation(selected);
break;
case 2:
tipo = tipo.cbV4;
clase = "V4";
unselected = new Animation(0.2f,cargarSprites("2B",".png",1));
selected = new Animation(0.2f,cargarSprites("2",".png",2),Animation.PlayMode.LOOP_PINGPONG);
setAnimation(unselected);
break;
case 3:
tipo = tipo.cbV8;
clase = "V8";
unselected = new Animation(0.2f,cargarSprites("3B",".png",1));
selected = new Animation(0.2f,cargarSprites("3",".png",2),Animation.PlayMode.LOOP_PINGPONG);
setAnimation(unselected);
break;
case 4:
tipo = tipo.cbV16;
clase = "V16";
unselected = new Animation(0.2f,cargarSprites("4B",".png",1));
selected = new Animation(0.2f,cargarSprites("4",".png",2),Animation.PlayMode.LOOP_PINGPONG);
setAnimation(unselected);
break;
}
}
//setTexture
public void setTextura(Texture t){
int ancho = t.getWidth();
int alto = t.getHeight();
setWidth(ancho);
setHeight(alto);
region.setRegion(t);
}
//This function returns the sprite array
public Array<TextureRegion> cargarSprites(String imagen, String ext, int index){
TextureRegion frames[] = new TextureRegion[index];
for (int i = 0; i < index; i++){
if(imagen.length() < 2){
Texture t = new Texture(Gdx.files.internal(imagen + i + ext));
t.setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
frames[i] = new TextureRegion(t);
}else{
Texture t = new Texture(Gdx.files.internal(imagen + ext));
t.setFilter(Texture.TextureFilter.Linear, Texture.TextureFilter.Linear);
frames[i] = new TextureRegion(t);
}
}
Array<TextureRegion> framesArray = new Array(frames);
return framesArray;
}
public void setAnimation(Animation<TextureRegion> a)
{
setTextura(a.getKeyFrame(0).getTexture());
animacion = a;
}
public Rectangle getBoundingRectangle(){
area.set(getX(),getY(),getWidth(),getHeight());
return area;
}
//Act method (or UPDATE)
public void Act(float dt){
super.act(dt);
elapsedTime += dt;
moveBy(velocidadX * dt, velocidadY * dt);
}
public void draw(Batch batch, float parentAlpha){
Color c = getColor();
batch.setColor(c.r, c.g, c.b, c.a);
region.setRegion(animacion.getKeyFrame(elapsedTime));
if ( isVisible() )
batch.draw( region, getX(), getY(), getOriginX(), getOriginY(),
getWidth(), getHeight(), getScaleX(), getScaleY(), getRotation() );
}
}
表类:
//I do a loop to render all the boxes of my table
public void updateTableObjects(float dt){
for(int f=0;f<baterias.length;f++){
for(int c=0;c<baterias[f].length;c++){
baterias[f][c].act(dt);
}
}
}
PlayState类:
public class PlayState extends Estado {
private Texture background;
private Tabla tabla;
protected PlayState(GameStateManager gsm) {
super(gsm);
tabla = new Tabla();
background = new Texture("fondo_juego.png");
camara.setToOrtho(true,background.getWidth(),background.getHeight());
Image fondo = new Image(background);
}
@Override
public void update(float dt) {
handleInput();
}
@Override
public void handleInput() {
if(Gdx.input.isTouched()){
raton.set(Gdx.input.getX(), Gdx.input.getY(),0);
camara.unproject(raton);
if(raton.x > 173 && raton.y < 703)
tabla.buscarCubo(raton.x,raton.y);
System.out.println((int)raton.x + "," + (int)raton.y);
}
}
//I THINK HERE IS THE PROBLEM... I TRY TO PLACE THE METHOD THAT UPDATES
//ALL THE BOXES OF THE TABLE, BUT DIDNT WORK
@Override
public void render(SpriteBatch batch) {
batch.begin();
batch.draw(background,0,0, game.ANCHO, game.ALTO);
batch.end();
tabla.act(Gdx.graphics.getDeltaTime());
tabla.updateTableObjects(Gdx.graphics.getDeltaTime());
tabla.draw();
}
}
这里有什么问题?
答案 0 :(得分:0)
我想,也许,看一下您的代码时间,您应该尝试获取随机数的方式,因为您想要一个1-4之间的数字来进行切换,试试这个hermano:
Random rn = new Random();
int n = 4 - 1 + 1;
int i = rn.nextInt() % n;
int randomNum = 1 + i;
其中4是最大值,1是最小值,将来可能是你的变量。
我希望它有所帮助! Saludos atodoPanamá!
