本讲分析的是在原版（core+all dlc）环境下，一个Pawn可以用的Tools的所有来源。
重点要分析的是RimWorld.Pawn_MeleeVerbs下的方法GetUpdatedAvailableVerbsList，我把它贴在下面：

public List<VerbEntry> GetUpdatedAvailableVerbsList(bool terrainTools)
{meleeVerbs.Clear();verbsToAdd.Clear();if (!terrainTools){List<Verb> allVerbs = pawn.verbTracker.AllVerbs;for (int i = 0; i < allVerbs.Count; i++){if (IsUsableMeleeVerb(allVerbs[i])){verbsToAdd.Add(allVerbs[i]);}}if (pawn.equipment != null){List<ThingWithComps> allEquipmentListForReading = pawn.equipment.AllEquipmentListForReading;for (int j = 0; j < allEquipmentListForReading.Count; j++){List<Verb> list = allEquipmentListForReading[j].GetComp<CompEquippable>()?.AllVerbs;if (list == null){continue;}for (int k = 0; k < list.Count; k++){if (IsUsableMeleeVerb(list[k])){verbsToAdd.Add(list[k]);}}}}if (pawn.apparel != null){List<Apparel> wornApparel = pawn.apparel.WornApparel;for (int l = 0; l < wornApparel.Count; l++){List<Verb> list2 = wornApparel[l].GetComp<CompEquippable>()?.AllVerbs;if (list2 == null){continue;}for (int m = 0; m < list2.Count; m++){if (IsUsableMeleeVerb(list2[m])){verbsToAdd.Add(list2[m]);}}}}foreach (Verb hediffsVerb in pawn.health.hediffSet.GetHediffsVerbs()){if (IsUsableMeleeVerb(hediffsVerb)){verbsToAdd.Add(hediffsVerb);}}if (ModsConfig.AnomalyActive && pawn.IsMutant){foreach (Verb allVerb in pawn.mutant.AllVerbs){if (IsUsableMeleeVerb(allVerb)){verbsToAdd.Add(allVerb);}}}}else if (pawn.Spawned && !pawn.IsMutant){TerrainDef terrain = pawn.Position.GetTerrain(pawn.Map);if (terrainVerbs == null || terrainVerbs.def != terrain){terrainVerbs = Pawn_MeleeVerbs_TerrainSource.Create(this, terrain);}List<Verb> allVerbs2 = terrainVerbs.tracker.AllVerbs;for (int n = 0; n < allVerbs2.Count; n++){Verb verb = allVerbs2[n];if (IsUsableMeleeVerb(verb)){verbsToAdd.Add(verb);}}}float num = 0f;foreach (Verb item in verbsToAdd){float num2 = VerbUtility.InitialVerbWeight(item, pawn);if (num2 > num){num = num2;}}foreach (Verb item2 in verbsToAdd){meleeVerbs.Add(new VerbEntry(item2, pawn, verbsToAdd, num));}return meleeVerbs;bool IsUsableMeleeVerb(Verb v){if (v.IsMeleeAttack){return v.IsStillUsableBy(pawn);}return false;}
}

具有一定C#基础的同学一看就懂了，好的，本期教程到此为止，谢谢大家【

咳咳，然而该教程依然是面向XML的教程，所以我将把上述天书翻译为正常的教程内容。
首先，一个Pawn本身会自带一定的Tools，比如人类的左拳右拳牙齿头槌：

Core\ThingDefs_Races\Races_Humanlike.xml，line16开始

<tools><li><label>left fist</label><labelNoLocation>fist</labelNoLocation><capacities><li>Blunt</li></capacities><power>8.2</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>LeftHand</linkedBodyPartsGroup><surpriseAttack><extraMeleeDamages><li><def>Stun</def><amount>14</amount></li></extraMeleeDamages></surpriseAttack></li><li><label>right fist</label><labelNoLocation>fist</labelNoLocation><capacities><li>Blunt</li></capacities><power>8.2</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>RightHand</linkedBodyPartsGroup><surpriseAttack><extraMeleeDamages><li><def>Stun</def><amount>14</amount></li></extraMeleeDamages></surpriseAttack></li><li><label>teeth</label><capacities><li>Bite</li></capacities><power>8.2</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>Teeth</linkedBodyPartsGroup><chanceFactor>0.07</chanceFactor><soundMeleeHit>Pawn_Melee_HumanBite_Hit</soundMeleeHit><soundMeleeMiss>Pawn_Melee_HumanBite_Miss</soundMeleeMiss></li><li><label>head</label><capacities><li>Blunt</li></capacities><power>5</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>HeadAttackTool</linkedBodyPartsGroup><ensureLinkedBodyPartsGroupAlwaysUsable>true</ensureLinkedBodyPartsGroupAlwaysUsable><chanceFactor>0.2</chanceFactor></li>
</tools>

Pawn自带的tools会多出一个常用的字段，为linkedBodyPartsGroup，即该Tool与身体部件绑定。具体来说，与其绑定的BodyPartsGroup内的身体部件的效率会以倍率的形式影响该Tool的伤害；而如果Group内的身体部件均已缺失，则该Tool的伤害为0，也就不会被使用。
与之相关的另一个字段是ensureLinkedBodyPartsGroupAlwaysUsable，如果填的是true，那么伤害倍率至少为0.4倍，那么即使绑定的所有部件均已缺失，也能正常使用。

除此之外，这里还有一个surpriseAttack的词条，这并非“暴击”的意思，而是突然袭击。
具体来说，这个机制只有一个触发条件：当野生的食肉动物触发狩猎工作（JobDriver_PredatorHunt）时，若该次攻击是对目标造成的第一次尝试攻击，且目标并非殖民者，那么会造成额外的效果。在原版，这个额外效果均为14*30tick（7秒）的晕眩。

还有一个出现的chanceFactor，它会影响随机选用tools时被选中的概率。（具体的选择逻辑后续讲吧）


第二个来源是手持的武器，这个就不再细讲了。
第三个来源是身上的装备，装备依然需要带有CompEquippable，与武器类似。
第四个来源是hediff，比如皇权里面的肘刀：

Royalty\HediffDefs\Hediffs_BodyParts_Prosthetic_Empire.xml

<HediffDef ParentName="ImplantHediffBase"><defName>ElbowBlade</defName><label>elbow blade</label><labelNoun>an elbow blade</labelNoun><description>An installed elbow blade. Extends at will from a hidden opening at the end of the ulna. Appearing without warning, it can be used for devastating slice attacks.</description><descriptionHyperlinks><ThingDef>ElbowBlade</ThingDef></descriptionHyperlinks><addedPartProps><solid>true</solid></addedPartProps><comps><li Class="HediffCompProperties_VerbGiver"><tools><li><label>blade</label><capacities><li>Cut</li></capacities><power>18</power><cooldownTime>2</cooldownTime><alwaysTreatAsWeapon>true</alwaysTreatAsWeapon><soundMeleeHit>MeleeHit_BionicSlash</soundMeleeHit><soundMeleeMiss>MeleeMiss_BionicSlash</soundMeleeMiss></li></tools></li></comps><spawnThingOnRemoved>ElbowBlade</spawnThingOnRemoved>
</HediffDef>

就是这里的comp里面的内容。当带有该comp的hediff出现在小人身上的时候，小人就能直接使用它作为近战来源。

第五个来源是异象DLC下的机制，变异的生物会获得来自变异提供的更多tools，在MutantDef.tools进行编辑。原版比较典型的是蹒跚怪获得的新tools：
Anomaly\Misc\Mutants.xml line87

 <tools><li><label>teeth</label><capacities><li>Bite</li></capacities><power>8.2</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>Teeth</linkedBodyPartsGroup><chanceFactor>1</chanceFactor><soundMeleeHit>Pawn_Melee_HumanBite_Hit</soundMeleeHit><soundMeleeMiss>Pawn_Melee_HumanBite_Miss</soundMeleeMiss></li><li><label>left hand</label><labelNoLocation>hand</labelNoLocation><capacities><li>Scratch</li></capacities><power>7.0</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>LeftHand</linkedBodyPartsGroup><chanceFactor>1.5</chanceFactor><alwaysTreatAsWeapon>true</alwaysTreatAsWeapon></li><li><label>right hand</label><labelNoLocation>hand</labelNoLocation><capacities><li>Scratch</li></capacities><power>7.0</power><cooldownTime>2</cooldownTime><linkedBodyPartsGroup>RightHand</linkedBodyPartsGroup><chanceFactor>1.5</chanceFactor><alwaysTreatAsWeapon>true</alwaysTreatAsWeapon></li>
</tools>

新增了一个牙齿，两个伤害类型为刮伤的左右手。这三个tools类似Pawn自带的tools，也是与身体部件绑定的。但可以发现它们的chanceFactor都被设置的很高，表达了泰南将其作为更高攻击性身体武器的想法。


第六个来源是地板。Core\TerrainDefs\Terrain_Natural.xml  line41

 <tools><li><label>dirt</label><capacities><li>KickMaterialInEyes</li></capacities><hediff>DirtInEyes</hediff><cooldownTime>1.5</cooldownTime></li>
</tools>

就是站在这种地形上可以使用这种tool，这里是把土踢进人眼睛里，是一个特殊的近战。

没了。下次再会。
