我想用“踢”方法实现英雄逃避的逻辑。对于英雄,设置了一定数量的“逃避”属性,在此基础上,其逃避百分比取决于该属性,例如“逃避”弓箭手为0.6,即有60%的几率规避“反踢”。如何正确实施此逻辑以及消息的结果,显示损坏或逃避
function Unit(maxHealth, basicDamage, evasion, type) {
this.maxHealth = maxHealth;
this.currentHeaalth = maxHealth;
this.basicDamage = basicDamage;
this.evasion = evasion;
this.type = type;
/*method for showing the status of life, true if the "health" is greater
than 0 and false if equal to or lower */
this.isAlive = function () {
return this.currentHeaalth > 0
};
/* a method that
shows the level of health*/
this.getFormattedHealth = function () {
return this.currentHeaalth + '/' + this.maxHealth + ' HP';
};
/*a method that returns the base damage of the heroand damage to the
weapon (if it is set)*/
this.getDamage = function () {
return (this.weapon ? this.weapon.getDamage() : 0) + this.basicDamage;
};
/* The method of hitting
the hero for the chosen purpose*/
this.kick = function (target) {
if (this.isAlive()) {
target.currentHeaalth = Math.max(0, target.currentHeaalth - this.getDamage());
}
return this;
};
/*method for showing all the characteristics of the hero and changes
with them*/
this.toString = function () {
return "Type - " + this.type + ", is alive - " + this.isAlive() + ", " + this.getFormattedHealth() + ', hero current damage - ' + this.getDamage() + ' points' +
", hero evasion - " + this.evasion;
}
}
function Archer(maxHealth, basicDamage, evasion) {
Unit.apply(this, arguments);
this.type = "archer";
}
var archer = new Archer(60, 5, 0.6);
function Swordsman(maxHealth, basicDamage, evasion) {
Unit.apply(this, arguments);
this.type = "swordsman";
}
var swordsman = new Swordsman(100, 10, 0.3)
while (archer.isAlive() && swordsman.isAlive()) {
archer.kick(swordsman);
swordsman.kick(archer);
}
console.log(archer.toString());
console.log(swordsman.toString());
最佳答案
编写一个函数,该函数根据逃避情况用10位0和1填充数字,并返回随机的1或0:
let evasion = 0.4,
probability = function() {
var notRandomNumbers = [],
maxEvasion = 0;
if ((evasion + '').split('.')[0] == 1 && (evasion + '').split('.')[1] == 0) {
maxEvasion = 10;
} else {
maxEvasion = (evasion + '').split('.')[1];
}
for (var i = 0; i < maxEvasion; i++) {
notRandomNumbers.push(1);
}
for (var i = 0; i < 10 - maxEvasion; i++) {
notRandomNumbers.push(0);
}
var idx = Math.floor(Math.random() * notRandomNumbers.length);
return notRandomNumbers[idx];
}
console.log('1 )', probability());
console.log('2 )', probability());
console.log('3 )', probability());
console.log('4 )', probability());
在
kick
功能中使用它。this.kick = function(target) {
if (this.isAlive()) {
target.currentHeaalth = Math.max(
0,
target.currentHeaalth - this.probability() * this.getDamage()
);
}
};
完整的代码是这样的:
function Unit(maxHealth, basicDamage, evasion, type) {
this.maxHealth = maxHealth;
this.currentHeaalth = maxHealth;
this.basicDamage = basicDamage;
this.evasion = evasion;
this.type = type;
/*method for showing the status of life, true if the "health" is greater
than 0 and false if equal to or lower */
this.isAlive = function() {
return this.currentHeaalth > 0;
};
/* a method that
shows the level of health*/
this.getFormattedHealth = function() {
return this.currentHeaalth + "/" + this.maxHealth + " HP";
};
this.probability = function() {
var notRandomNumbers = [],
maxEvasion = 0;
if (
(this.evasion + "").split(".")[0] == 1 &&
(this.evasion + "").split(".")[1] == 0
) {
maxEvasion = 10;
} else {
maxEvasion = (this.evasion + "").split(".")[1];
}
for (var i = 0; i < maxEvasion; i++) {
notRandomNumbers.push(1);
}
for (var i = 0; i < 10 - maxEvasion; i++) {
notRandomNumbers.push(0);
}
var idx = Math.floor(Math.random() * notRandomNumbers.length);
return notRandomNumbers[idx];
};
/*a method that returns the base damage of the heroand damage to the
weapon (if it is set)*/
this.getDamage = function() {
return (this.weapon ? this.weapon.getDamage() : 0) + this.basicDamage;
};
/* The method of hitting
the hero for the chosen purpose*/
this.kick = function(target) {
if (this.isAlive()) {
target.currentHeaalth = Math.max(
0,
target.currentHeaalth - this.probability() * this.getDamage()
);
}
};
/*method for showing all the characteristics of the hero and changes
with them*/
this.toString = function() {
return (
"Type: " +
this.type +
", is alive: " +
this.isAlive() +
", " +
this.getFormattedHealth() +
", hero current damage: " +
this.getDamage() +
" points" +
", hero evasion - " +
this.evasion
);
};
}
function Archer(maxHealth, basicDamage, evasion) {
Unit.apply(this, arguments);
this.type = "archer";
}
var archer = new Archer(60, 5, 0.6);
function Swordsman(maxHealth, basicDamage, evasion) {
Unit.apply(this, arguments);
this.type = "swordsman";
}
var swordsman = new Swordsman(100, 10, 0.3);
while (archer.isAlive() && swordsman.isAlive()) {
archer.kick(swordsman);
swordsman.kick(archer);
}
console.log(archer.toString());
console.log(swordsman.toString());
