職責: 判斷能秒人的傷害技能

鏈：技能鏈

Golang實現(xiàn)職責鏈模式時候，因為沒有繼承的支持，使用鏈對象包涵職責的方式，即：

鏈對象包含當前職責對象以及下一個職責鏈。
職責對象提供接口表示是否能處理對應請求。
職責對象提供處理函數處理相關職責。

2. 代碼實現(xiàn)

1. manager.go

下面是先定義一個職責鏈管理器,來幫助每個對象判斷它是否符合職責

package main
import "log"
// 職責鏈模式
type Manager interface {
	HaveKill(attack int) bool                         // 是否擊殺
	HandleAttackRequest(skillId int, attack int) bool // 連招
}
// 連招
type SkillChain struct {
	Manager
	successor *SkillChain
}
func (r *SkillChain) SetSuccessor(m *SkillChain) {
	r.successor = m
}
func (r *SkillChain) HandleAttackRequest(skillId int, attack int) bool {
	// 傷害是否滿足擊殺
	if r.Manager.HaveKill(attack) {
		return r.Manager.HandleAttackRequest(skillId, attack) // 釋放連招把并且播報
	}
	if r.successor != nil {
		log.Printf("技能%d,傷害%d有點低不太行啊!推薦你換其他技能\n", skillId, attack)
		return r.successor.HandleAttackRequest(skillId, attack)
	}
	return false
}
func (r *SkillChain) HaveKill(attack int) bool {
	return true
}

2. skill1_manager.go

給英雄技能一對象實現(xiàn)對應的職責

package main
import (
	"fmt"
)
const (
	Hp = 8000
	SkillOne =1
	SkillTwo =2
	SkillThree =3
)
type SkillOneManager struct {
}
func NewSkillOneManager() *SkillChain {
	return &SkillChain{
		Manager:&SkillOneManager{},
	}
}
func (s SkillOneManager) HaveKill(attack int) bool {
	return attack>Hp
}
func (s SkillOneManager) HandleAttackRequest(skillId int, attack int) bool {
	fmt.Printf("技能 %d 進來了\n",skillId)
	if skillId==SkillOne{
		fmt.Printf("技能 %d滿足條件釋放 造成 %d 傷害\n", skillId, attack)
		return true
	}
	fmt.Printf("技能 %d 滿足條件釋放 造成 %d 傷害\n", skillId, attack)
	return false
}

3. skill2_manager.go

package main
import (
	"fmt"
)
type SkillTwoManager struct {}
func NewSkillTwoManager() *SkillChain {
	return &SkillChain{
		Manager:&SkillTwoManager{},
	}
}
func (s SkillTwoManager) HaveKill(attack int) bool {
	return attack>Hp
}
func (s SkillTwoManager) HandleAttackRequest(skillId int, attack int) bool {
	if skillId==SkillTwo{
		fmt.Printf("技能 %d 滿足條件釋放 造成 %d 傷害\n", skillId, attack)
		return true
	}
	fmt.Printf("技能 %d不 滿足條件釋放 造成 %d 傷害\n", skillId, attack)
	return false
}

4. skill3_manager.go

package main
import (
	"fmt"
)
type SkillThreeManager struct {
}
func NewSkillThreeManager() *SkillChain {
	return &SkillChain{
		Manager:&SkillThreeManager{},
	}
}
func (s SkillThreeManager) HaveKill(attack int) bool {
	return attack>Hp
}
func (s SkillThreeManager) HandleAttackRequest(skillId int, attack int) bool {
	if skillId==SkillThree{
		fmt.Printf("技能 %d 滿足條件釋放 造成 %d 傷害\n", skillId, attack)
		return true
	}
	fmt.Printf("技能 %d不 滿足條件釋放 造成 %d 傷害\n", skillId, attack)
	return false
}

5. mian.go

package main
type (
	HeroId  = int
	SkillId = int
	Attack  = int
)
type DaJi struct {
	HeroId    HeroId
	Name      string
	SkillInfo map[SkillId]Attack
}
func NewDaJi(skillInfo map[SkillId]Attack) *DaJi {
	return &DaJi{HeroId: 1, Name: "妲己", SkillInfo: skillInfo}
}
func main() {
	c1 := NewSkillOneManager()
	c2 := NewSkillTwoManager()
	c3 := NewSkillThreeManager()
	c1.SetSuccessor(c2)
	c2.SetSuccessor(c3)
	var c Manager = c1
	skillInfo := make(map[SkillId]Attack, 3)
	skillInfo[SkillOne] = 7000  // 技能一  傷害
	skillInfo[SkillTwo] = 9000  // 技能一  傷害
	skillInfo[SkillThree] = 10000 // 大招  傷害
	daji:=NewDaJi(skillInfo)
	c.HandleAttackRequest(SkillOne, daji.SkillInfo[SkillOne])
	c.HandleAttackRequest(SkillTwo, daji.SkillInfo[SkillTwo])
	c.HandleAttackRequest(SkillThree, daji.SkillInfo[SkillThree])
}
