动画的父类Action抽象类
public abstract class Action implements Pool.Poolable {
protected Actor actor;
private Pool pool;
protected Actor target;
public abstract boolean act(float f);
public void restart() {
}
public void setActor(Actor actor2) {
this.actor = actor2;
if (this.target == null) {
setTarget(actor2);
}
if (actor2 == null && this.pool != null) {
this.pool.free(this);
this.pool = null;
}
}
public Actor getActor() {
return this.actor;
}
public void setTarget(Actor target2) {
this.target = target2;
}
public Actor getTarget() {
return this.target;
}
@Override // com.badlogic.gdx.utils.Pool.Poolable
public void reset() {
this.actor = null;
this.target = null;
this.pool = null;
restart();
}
public Pool getPool() {
return this.pool;
}
public void setPool(Pool pool2) {
this.pool = pool2;
}
public String toString() {
String name = getClass().getName();
int dotIndex = name.lastIndexOf(46);
if (dotIndex != -1) {
name = name.substring(dotIndex + 1);
}
if (name.endsWith("Action")) {
return name.substring(0, name.length() - 6);
}
return name;
}
}
这个抽象类，比较简单，当前进行动做的演员是以及演员的回收重置。
RunableAction
它是在适当的时候执行一个“线程操作”（它仅仅是作为一个普通的方法使用，并没真正的当线程来使用）
适当的时候：重复 顺序 等待的时候执行run方法里面的内容。

这个里面其实和之前写的一样，这个 应该是存在许多的无用代码。
