在我的游戏中,玩家有两个主要状态:STATIC和MOVING。
我想再添加两个状态作为STATIC状态的子状态,如UP和DOWN。
public enum PlayerState {
STATIC,MOVING;
public boolean isMoving() {
return this == MOVING;
}
public boolean isStatic() {
return this == STATIC;
}
}
如何在枚举中添加此子状态并访问它?
现在我在播放器类中以
的形式访问它private NestState state = NestState.STATIC;
public void moving() {
state = NestState.MOVING;
}
public void staticState() {
state = NestState.STATIC;
}
public boolean isStatic() {
return state.isStatic();
}
public boolean isMoving() {
return state.isMoving();
}

我可以看到两个简单的解决方案,可以让你拥有状态和子状态。第一个是扩展你目前的状态。
public enum PlayerState {
STATIC_STILL, STATIC_UP, STATIC_DOWN, MOVING_LEFT, MOVING_RIGHT;
public boolean isMoving() {
if(this == MOVING_LEFT ||
this == MOVING_LEFT){
return true;
}
return false;
}
public boolean isStatic() {
if(this == STATIC_STILL ||
this == STATIC_UP ||
this = STATIC_DOWN){
return true;
}
return false;
}
}
第二种选择是创建与此
分开的第二组状态public enum PlayerSubState {
UP,DOWN,LEFT,RIGHT;
}
你的玩家将拥有PlayerState和PlayerSubState。
