正常代码
<recipe name=”ammoShotgunShell” time=”-1″ area=”ulmStationBallistics_2″ tags=”learnable”>
<ingredient name=”ammo9mmBulletBall”/></recipe>
尝试优化代码：（不生效）请问有其他方法实现吗？
代码一
<!– 霰弹枪子弹转换配方 –>
<recipe name=”ammoShotgunShell” time=”-1″ area=”ulmStationBallistics_2″ tags=”learnable”>
<ingredient name=”ammo9mmBulletBall”/>
<ingredient name=”ammo9mmBulletAP”/>
<ingredient name=”ammo9mmBulletHP”/>
<ingredient name=”ammo44MagnumBulletBall”/>
<ingredient name=”ammo44MagnumBulletAP”/>
<ingredient name=”ammo44MagnumBulletHP”/>
<ingredient name=”ammo762mmBulletBall”/>
<ingredient name=”ammo762mmBulletAP”/>
<ingredient name=”ammo762mmBulletHP”/>
</recipe>
代码二、
<recipe name=”ammo9mmBulletBall” time=”-1″ area=”ulmStationBallistics_2″ tags=”learnable”>
<ingredient name=”ammo44MagnumBulletBall,ammo762mmBulletBall,ammoShotgunShell,ammo9mmBulletBall”/></recipe>
代码三、
<recipe name=”ammo9mmBulletBall,ammo9mmBulletHP,ammo9mmBulletAP” time=”-1″ area=”ulmStationBallistics_2″ tags=”learnable”>
<ingredient name=”ammo44MagnumBulletBall,ammo762mmBulletBall,ammoShotgunShell,ammo9mmBulletBall”/></recipe>
实测代码一没问题
代码一的配方的tags是learnable，需要学习，但是初始人物未习得该配方，所以未习得的配方的所有材料都显示"未知材料"，这是正常的。
去掉tags="learnable", 如下：
游戏内显示：
所以代码一没问题
注：代码一、
此代码可用,但是提示的是未知配方
每种子弹的都得重新写一个吧

<recipe name="ammoCrossbowBoltIron" count="1" craft_area="workbench" tags="workbenchCrafting">
<ingredient name="ammoArrowIron" count="1"/>
</recipe>
<recipe name="ammoCrossbowBoltSteelAP" count="1" craft_area="workbench" tags="workbenchCrafting">
<ingredient name="ammoArrowSteelAP" count="1"/>
</recipe>
<recipe name="ammoCrossbowBoltFlaming" count="1" craft_area="workbench" tags="workbenchCrafting">
<ingredient name="ammoArrowFlaming" count="1"/>
</recipe>
<recipe name="ammoCrossbowBoltExploding" count="1" craft_area="workbench" tags="workbenchCrafting">
<ingredient name="ammoArrowExploding" count="1"/>
</recipe>
<recipe name="ammoCrossbowBoltStone" count="1" craft_area="workbench" tags="workbenchCrafting">
