我写了一个角色的技能代码，作用是释放几段闪电。由于要改变实现办法，我不想抛弃，就把这个技能类记录下来。
class Skill_Beam :public SkillBase{
public:
virtual ~Skill_Beam(){}
Skill_Beam(ISkillAbility *launcher):
SkillBase(launcher){
//技能名称
set_skill_name("Beam");
set_skill_icon_name("Beam.png");
m_isSkillEnd = true;//技能结束状态
set_skill_description("Beam description.");
set_mana_consume(40);
set_m_cooldown_time(5.0);
}
public:
virtual int get_skill_point_to_upgrade(){
return 1;
}
virtual bool launch_skill(){
//新的计时器
m_clock = new sf::Clock();
m_clock->restart();
//技能状态没有结束
m_isSkillEnd = false;
//获取释放者位置和朝向信息
m_launcherPosition = m_launcher->ISkillAbility_get_position_and_size();
m_isLauncherFaceToRight = m_launcher->ISkillAbility_is_sprite_face_to_right();
//重置光柱未移动状态
memset(m_isBeamMoved,0,sizeof(m_isBeamMoved));
m_beamMoveDistance = 20;//每次移动光柱距离
//设置光柱数量和起始位置
m_beamNumber = 2;
m_beamPosition[0] = sf::Vector2i(m_launcherPosition.left+(m_isLauncherFaceToRight?20:-20),m_launcherPosition.top-30);

技能效果
在update函数里面，判断技能释放后的时间，并且在特定时间对所有的光柱进行位移和制造伤害。
在launch_skill里面建立技能时钟，并且设置技能的参数。因为是测试没有根据技能等级去分别设置。
EffectSystem::new_effect是创建特效。这里创建了光柱特效
新的类代码

加了技能伤害后的技能效果
