2*num

forced:true,
trigger:{
source:"damageBegin",
},
filter:function (event,player){
return player.hp==player.maxHp;
},
content:function (){
trigger.num++;
},
这个，这种多找找类似的代码改改就行。我这个也是找几个类似的想出来的。

skill={
forced:true,
trigger:{
source:"damageBegin",
},
filter:function (event,player){
return player.hp>0;
},
content:function (){
var num=trigger.num;
trigger.num+=((2*num)-num);
},
}
