我可以在另一个函数中包含一个函数吗？ [英] Can I include a function inside of another function?

问题描述

是否可以在一个函数中包含另一个函数？为了学习功能，我试图用PHP创建一个战斗序列。顺序看起来像这样：

1. 骰子会滚动，将数字分配给变量;
   
2. Hero1攻击结果被打印;


3. 骰子会滚动，将数字分配给变量;
   
4. 将打印Hereo2攻击结果;
   
5. 骰子会滚动，将数字分配给变量;
   
6. 打印Hero3攻击结果。

掷骰子将是一个自动化的功能。代码如下：

 <？ 
 rollSim（）; 
 combatSim（）; 
 
函数rollSim（）{
 $ hAttack = rand（1,20）; 
 $ mDefend = rand（1,20）; 
 $ mAttack = rand（1,20）; 
 $ hDefend = rand（1,20）; 
 $ mDamage = rand（10,25）; 
 $ hDamage = rand（1,20）; 
} // end rollSim 
 
 function combatSim（）{
 rollSim（）; 
 if（$ hAttack> $ mDefend）{
 print英雄命中怪物造成$ hDamage伤害。< br>; 
} else if（$ hAttack< = $ mDefend）{
 print英雄错过了怪物。; 
} 
} // end combatSim 
 
？> 
  

解决方案

您的 rollSim（）函数应返回滚动的数字，而不是设置一些变量并尝试在其他函数中使用它们。我会将它们返回到一个关联数组中，如下所示：

  function rollSim（）{
 $ roll ['hAttack '] = rand（1,20）; 
 $ roll ['mDefend'] = rand（1,20）; 
 $ roll ['mAttack'] = rand（1,20）; 
 $ roll ['hDefend'] = rand（1,20）; 
 $ roll ['mDamage'] = rand（10,25）; 
 $ roll ['hDamage'] = rand（1,20）; 
 
 return $ roll; 
 
 
 function combatSim（）{
 $ roll = rollSim（）; 
 $ b $ if如果（$ roll ['hAttack']> $ roll ['mDefend']）{
 print英雄打到{$ roll ['hDamage']}受到伤害。峰; br>中; 
} else if（$ roll ['hAttack']< = $ roll ['mDefend']）{
 printHero错过了怪物。 
} 
} 
  

Is it possible to include one function inside another? To learn functions, I'm trying to create a combat sequence using PHP. The sequence would look like this:

1. Dice would roll, assigning numbers to variables;
2. Hero1 attack results are printed;
3. Dice would roll, assigning numbers to variables;
4. Hereo2 attack results are printed;
5. Dice would roll, assigning numbers to variables;
6. Hero3 attack results are printed.

The dice rolling would be an automated function. Here is the code:

<?
rollSim();
combatSim();

function rollSim() {
    $hAttack = rand(1,20);
    $mDefend = rand(1,20);
    $mAttack = rand(1,20);
    $hDefend = rand(1,20);
    $mDamage = rand(10,25);
    $hDamage = rand(1,20);
} // end rollSim

function combatSim() {
    rollSim();
    if ($hAttack>$mDefend) {
        print "Hero hit monster for $hDamage damage.<br>";
    } else if ($hAttack<=$mDefend) {
        print "Hero missed monster.";
    }
} // end combatSim

?>

解决方案

Your rollSim() function should return the rolled numbers rather than setting some variables and trying to use them in your other function. I would return them in an associative array, like this:

function rollSim() {
    $roll['hAttack'] = rand(1,20);
    $roll['mDefend'] = rand(1,20);
    $roll['mAttack'] = rand(1,20);
    $roll['hDefend'] = rand(1,20);
    $roll['mDamage'] = rand(10,25);
    $roll['hDamage'] = rand(1,20);

    return $roll;
}

function combatSim() {
    $roll = rollSim();

    if ($roll['hAttack'] > $roll['mDefend']) {
        print "Hero hit monster for {$roll['hDamage']} damage.<br>";
    } else if ($roll['hAttack'] <= $roll['mDefend']) {
        print "Hero missed monster.";
    }
}
