技能mod讨论 请教 ~技能二选一编写方法

例如： A B 两个技能， 学习A 就不能学习 B ，学习B 就不能学习 A 

我尝试过用过 学习A技能前置条件B等级为0 ，或者相反 

<append xpath=”/progression/attributes”>

<attribute name=”qiangli” name_key=”skillqiangliName” desc_key=”skillqiangliNameDesc” icon=”ui_game_symbol_survival” min_level=”0″ max_level=”10″ base_skill_point_cost=”1″ cost_multiplier_per_level=”1″>

    <level_requirements level=”1″><requirement name=”PlayerLevel” target=”self” operation=”GTE” value=”1″ desc_key=”qiangli01″/></level_requirements>

<level_requirements level=”2″><requirement name=”PlayerLevel” target=”self” operation=”GTE” value=”1″ desc_key=”qiangli01″/></level_requirements>

<level_requirements level=”8″><requirement name=”PlayerLevel” target=”self” operation=”GTE” value=”1″ desc_key=”qiangli01″/></level_requirements>

<level_requirements level=”9″><requirement name=”PlayerLevel” target=”self” operation=”GTE” value=”1″ desc_key=”qiangli01″/></level_requirements>

<level_requirements level=”10″><requirement name=”PlayerLevel” target=”self” operation=”GTE” value=”1″ desc_key=”qiangli01″/></level_requirements>

    <level_requirements level=”1″><requirement name=”ProgressionLevel” progression_name=”qianxing” operation=”GTE” value=”1″ desc_key=”xxxxxLevel”/></level_requirements> 

 （但问题是进游戏后直接弹出，所以这段代码是有问题的，还望知道的人能帮忙处理处理）
