Question

我正在开发一个简单的文字对战游戏，并且在计算战斗后应该获得多少XP时遇到一些问题，这是我想要考虑的几个因素：

1）如果玩家击败同级别的玩家，玩家当然应该获得良好的XP

2）如果玩家击败了更高级别的玩家，玩家应该获得优秀的XP

3）如果玩家击败较低级别的玩家，玩家应该获得较差的XP。

4）上面应该很好地扩展，即如果玩家A是10级并且与9级或11级玩家B战斗，差异不应该是巨大的（他们当然会获得更多XP以击败11级角色但是我们不会指望这是巨大的），但如果他要在5级或15级战斗，这种差异应该是巨大的。

在计算在所有场景中运行良好的东西时遇到问题，目前我的XP表如下所示：

Current Level   XP Needed   Increase from Last Level
1   30  0
2   65  35
3   106 41
4   154 48
5   210 56
...
10  672 123

在PHP中，我的代码如下所示，以计算所需的XP：

$offset = 30;
$multiplier = 1.17;
$base = $prevXp * $multiplier;

$xp = $base + $offset;

我尝试了一些不同的东西，但我对它们中的任何一个都没有留下深刻印象，我想计算两个玩家之间XP的差异，然后使用某种倍增器，但我没有'迄今为止对结果印象深刻。

任何帮助/意见都将不胜感激。

这是我用于FB游戏的战斗方法。您可能会发现它很有用。

public function fight(Player $attacker, Player $defender){
      $return = 'Attacking '.$defender->getName().'
';
      // if the defener has greater def than attackers attack, repel the attack
      // if the attacker has greater attack then the denfenders defense, penetrate
      if($attacker->getAttack() > $defender->getDefense()){
        $attacker->takeTemper(1);
        // penetration -- that's what she said!!!
        // figure out how much to damage each player
        $dmgDefender = rand(5, 25);
        $defender->takeHP($dmgDefender);
        $dmgAttacker = rand(0, 10);
        // figure out the reward
        // give between 1 and 5 XP and 10% of the defenders money
        $gainedXP = rand(1, 5);
        $attacker->addXP($gainedXP);
        $gainedMoney = floor($defender->getMoney() * .1);
        $attacker->addMoney($gainedMoney);
        $defender->takeMoney($gainedMoney);
        $return .= 'You won the fight and gained '.$gainedXP.' XP and $'.$gainedMoney.'
';
        if($dmgAttacker > 0){
          $return .= 'Unfortuantely you took '.$dmgAttacker.' damage in the fight.  The good news is you did '.$dmgDefender.' damage to '.$defender->getName().'
';
          $attacker->takeHP($dmgAttacker);
        }
        // check if the player leveled
        $nextLevelXP = $this->_level->levelXP( $attacker->getLevel() + 1 );
        if( ( $attacker->getXP() >= $nextLevelXP ) ){
          $gainedFounderPoints = $this->gainLevel($attacker);
          $return .= 'You gained a level';
          if($gainedFounderPoints > 0)
            $return .= ' and '.$gainedFounderPoints.IMG_FOUNDER_POINT;
          $return .= '
';
        }
      } else {
        // attack deflected
        $return .= 'The attack was deflected by '.$defender->getName().'
';
        // reward defender -- how about 10% of the attackers money?
        $reward = ceil($attacker->getMoney() * .1);
        if($reward > 0){
          // demerit attacker
          $attacker->takeMoney($reward);
          $defender->giveMoney($reward);
          $return .= 'You lost $'.$reward.'
';
        } else {
          // the attacker is broke ... take his XP!!! -- 1 percent
          $reward = ceil($attacker->getXP() * .01);
          $attacker->takeXP($reward);
          $defender->addXP($reward);
          $return .= 'You lost '.$reward.' XP
';
        }
      }
      // save data
      $attacker->save();
      $defender->save();

      // output
      return $return;
    }

Answer 2

这很简单，但符合您的标准

xpGain = getbasexp(); //whatever you were doing before
xpGain *= opponentxp * 1.0 / playerxp;
