7-5 灵活使用优先级






灵活使用tactics优先级可以弄出较好的效果，例如给城堡添加添加上像城镇中心的攻击，驻守人数越多，攻击越高,但是没人驻守时任然能攻击。


可以这样说，在这个教程出来之前（或者有类似这样的单位被制作出来），95%的人都是想不出可以这样做的。



tactics文件最底部的tactic中的action语句是可以增加优先顺序的，只需要在action后面添加上priority="X"，X值越大，优先级越高。





        举个例子：远程单位的齐射攻击分别设定了远距离攻击、近战攻击与攻城攻击的action，远距离攻击的priority值为100，近战攻击的priority值为25，攻城攻击的priority值为75。



        这个齐射攻击设定了三种攻击，那么为什么一般情况下只会远距离射击，而不会使用近战或攻城？

        因为远距离攻击的priority为100是几个设定中最高的，所以这个单位的齐射攻击会优先采用远距离攻击。



        但是为什么攻击建筑不是远距离攻击呢？

        因为远距离攻击的对象只定义了"Unit"，只能攻击单位，所以远距离无法攻击建筑物，当需要攻击建筑物的时候，会采用下一个优先等级较高的攻击，(如果不能攻击建筑的话则继续判断)，因此单位攻击建筑物的时候会主动切换到攻城动作。



        齐射攻击有时候会自动转换成近战攻击，原因也是与攻城攻击一样的：

        因为远距离射击有最短射击距离2，当距离小于2的时候会才采用攻城攻击，但是攻城攻击不能攻击单位，所以最后采用了可以攻击单位的近战攻击。



        还有一点是如果在齐射模式打船是远距离攻击的，在近战则是攻城攻击的，这是因为船只单位标签有unit，所以远距离攻击能攻击船只；而近战攻击在tactics并没有添加远距离攻击的action，所以只能采用攻城攻击（这句话看不懂的话，我补充一点：攻城攻击的对象是LogicalTypeShipsAndBuildings；VolleyAttack的优先级比BuildingAttack要高。）。







不说那么多了，来直接看例子吧：给城堡添加“当有单位驻守后，额外增加攻击”的功能。

需要用上这几个语句：


 
		<activeifcontainsunits>1</activeifcontainsunits>

当有单位驻守的时候，才开启攻击

 
		<damagefactorcap>X</damagefactorcap>
 当驻守单位达到X后，停止增加伤害 
		<scalebycontainedunits>1</scalebycontainedunits>
 驻守一个单位增加一次伤害（单位攻击力），该数值只能为1


如果只是把几个语句加上去的确是可以增加攻击，但是只能在有单位驻守时才能攻击，那么怎样让不驻守单位也能攻击？这时候就要用上优先级了。


首先在城堡的tactics文件复制粘贴一个action，然后改名，再把那三个语句加上去。


例如：





	<action>
		<name stringid="38133">ContainRangedAttack</name>
		<type>Attack</type>
		<attackaction>1</attackaction>
		<rangedlogic>1</rangedlogic>

		<scalebycontainedunits>1</scalebycontainedunits>

		<aimbonus>0</aimbonus>

		<projectile>InvisibleProjectile</projectile>
		<impacteffect>effects\impacts\gun</impacteffect>
		<rate type="Unit">1.0 </rate>
		<instantballistics>1</instantballistics>
	</action>

</tactics>



然后在底部的tactic语句把action写上去，priority要比原来的远距攻击设定要高，这样的话城堡会先优先采用有驻守单位的攻击，当没有人驻守在城堡，新添加的攻击会自动关闭，接着根据优先级顺序切换回原本的远距攻击。另外新攻击的priority值要比炮轰攻击的设定要低，才不会把炮轰攻击给覆盖掉。
















最后在protoy把新添加远距攻击的攻击力写上去，就完成了，进入游戏看结果吧。

不知道你留意到没，为了方便我是直接改良了两张卡片，一张给城堡增加10%攻击力，另一张设定坚固城堡的科技状态为作用中，都给城堡添加了攻击力，但是techtreey.xml这几个卡片（科技）都没有给定义增加新的远距攻击的攻击力，所以新的远距攻击依然是30*X不变。

其他的科技或者卡片自己添加上去吧，数量有点多，大概有五六个吧。




另外如果你想给炮轰攻击也添加上这个效果的话，方法都是一样的，不过要记得在techtreey.xml的强化城堡科技加上启用新炮轰攻击的语句。

对3.0版本的后续补充

在protoy.xml或tactics添加该句<DamageArea>1.000000</DamageArea>(范围伤害语句)后无论驻守多少人，虽然攻击力数值上升了，但实际攻击力不会上升。所以炮轰攻击你自己抉择吧，是要驻守增加攻击力还是要保留范围伤害。
