首先，要理解毒的原理——永续target，既取得目标后，利用常时reversaldef使其一直维持下去。

第一步就是先要取得对方的目标，分成三种手段，hitdef、projectile以及reversaldef，因为proj默认归属于本体，所以即使 helper的放出的proj击中了目标，取得target的也只是本体的，所以排不上用场。。。在这里我先拿一个简单的hitdef的版本给大家演示一下

基本构思是给kfm加一个用helper做成的飞行道具，击中对方后使其中毒 

先给飞行道具来个图，我的选择是，这个看个人喜好的，没图也无所谓

用FFU打开人物，导入已经处理成256色且底色透明的飞行道具的图片，详略

然后再添加动画，随便给个没有被占用的动画编号，详略

如果你允许被击落的话，可以加上蓝框配合destroyself，详略
另外红框越大，攻击范围越大，你懂的

然再添加一组动画，不需要画任何攻击或者受击框

到这sff和air的准备就完成了，然后开始写代码

我这边为了方便，直接选择在在kfm的轻拳状态（statedef 200）发射helper
[Statedef 200]
type = S ;State-type: S-stand, C-crouch, A-air, L-liedown
movetype= A ;Move-type: A-attack, I-idle, H-gethit
physics = S ;Physics: S-stand, C-crouch, A-air
juggle = 1 ;Number of air juggle points move takes
;Commonly-used controllers:
velset = 0,0 ;Set velocity (x,y) (Def: no change)
ctrl = 0 ;Set ctrl (Def: no change)
anim = 200 ;Change animation (Def: no change)
poweradd = 20 ;Power to add (Def: 0)
sprpriority = 2 ;Set p1's sprite layering priority to 2 (in front) 

[State ]
type = Helper;召唤援护
triggerall = !numhelper(12345);不存在helper(12345)时召唤，确保只召唤一个
trigger1 = AnimElem = 3;轻拳使用的动画的第三张图时发射
helpertype = player;helper类型，我选palyer型是因为-2下的代码对其他类型不起作用
ID = 12345;ID配合上面的!numhelper(12345)以及待会在statedef-2下的selfstate
name = "paopao"; helper的名字，起不起无所谓
postype = p1;位置类型
pos = 44,-67;出现位置，改变数字移动坐标，详略
stateno = 12345;helper被召唤出来时的初始状态
ownpal = 1;不会受本体的PalFX影响而变色
ignorehitpause = 1
supermovetime = 999999
pausemovetime = 999999

然后是helper的状态，这边只讲比较重要的一些
[statedef 12345]
Type = A
moveType= A
physics = N
juggle = 8
poweradd= 0
velset = ifelse(NumTarget=0,3,0),0;未获得目标之前保持朝着面对方向3的速度，获得则为0
ctrl = 0
sprpriority = 3

[State ];允许离开屏幕
Type = ScreenBound
Trigger1 = IsHelper
Value = 0
movecamera = 0
IgnoreHitPause = 1

[State ];不会对玩家造成推挤
Type = PlayerPush
Trigger1 = IsHelper
Value = 0
IgnoreHitPause = 1 

[State ];未获得目标之前保持带有红框的动画
Type = ChangeAnim
Trigger1 = NumTarget= 0
Value = 12345
IgnoreHitPause = 1 

[State ];未获得目标之前保持攻击活动状态(A=攻击、H=受击、I=啥都没干)
type = StateTypeSet
trigger1 = NumTarget = 0
trigger2 = NumTarget > 0
trigger2 = Target,IsHelper
trigger3 = Anim = 12345
movetype = A 

[State ];hitdef用来击中对方取得目标
Type = Hitdef
Trigger1 = NumTarget = 0;没有目标时发动
trigger1 = !Target,IsHelper;确保目标不是helper而是敌人本体
damage = 20,5
getpower = 0,0
givepower = 0,0
pausetime = 0,9
attr = S,SP
guardflag = MA
animType = heavy
air.animType = back
priority = 5, hit
sparkno = -1;火花，我这边图方便没写
guard.sparkno = 40
sparkxy = 0, 0
hitsound = -1
guardsound = -1
ground.Type = low
air.Type = high
air.hittime = 8
ground.slidetime = 13
ground.hittime = 17
ground.velocity = -7, 0 
air.velocity = -3, -7
fall.recover = 0
air.fall = 1
yaccel = .5
envshake.time = 16
envshake.freq = 60
envshake.ampl = 4
numhits = 0 

[State ];放下目标
Type = TargetDrop
Trigger1 = NumTarget > 0
Trigger1 = Target,IsHelper || !Target,Alive ;目标为helper或者目标已死亡
IgnoreHitPause = 1 

[State ];获得目标后改变动画，获得目标后切换到无判定框的动画
Type = ChangeAnim
Trigger1 = NumTarget != 0
Value = 54321
IgnoreHitPause = 1 

[State ];获得目标后改变为非攻击且非受击活动状态
type = StateTypeSet
trigger1 = NumTarget > 0
trigger1 = !Target,IsHelper
trigger2 = Anim = 54321
movetype = I 

[State ];获得目标绑定到本体，以便于监视
type = BindToRoot
trigger1 = NumTarget > 0
trigger1 = !Target,IsHelper;确认目标不是helper
IgNoreHitPause = 1 

击中目标后绑回到本体↑

[State ];获得目标后常时当身，从而维持永续
Type = ReversalDef
Trigger1 = NumTarget > 0;目标大于0时发动
trigger1 = !Target,IsHelper;确保获得的目标不是helper
Reversal.Attr = SCA,AA,AP,AT
PauseTime = 0,0
SparkNo = -1
HitSound = -1
numhits = 0
IgnoreHitPause = 1 

[State ];目标生命减少，毒的效果体现
type = TargetLifeAdd
triggerall = RoundState = 2
triggerall = !Target,IsHelper
triggerall = NumTarget != 0
trigger1 = Gametime%12 = 0 ;每隔12帧执行一次，1帧为60分之1秒，直接写1就是每帧执行，数字越大，发动间隔越大
value = -5;每次减少的生命量，无节操的话写个-99999999之类的
kill = 0;确保不会毒死人
IgnoreHitPause = 1 

[State ];helper自灭，自灭之后毒自动解除
type = DestroySelf
trigger1 = !Ishelper(12345);如果id不为12345直接自灭
trigger2 = time > 360;6秒后自灭
IgnoreHitPause = 1

最后在[statedef -2]下面加上一段
[state ]
type = selfstate
trigger1 = IsHelper(12345)
trigger1 = stateno != 12345
value = 12345
ignorehitpause = 1

以上就是简单的毒的制作，如果想要应用于凶恶的话
可以写在-3下常时召唤，将红框改成最大，最初的目标也用常时reversaldef来获取，不写destroyself，配合targetstate导入超即死状态、roundstateno > 2时发动普通死宣等等
