天灾导弹防御塔 - C# 实现计划
本文档包含构建“天灾导弹防御塔”所需的全部C#类的源代码。这些代码基于 Rimatomics 的跨地图打击框架，并与我们自己的 Projectile_CruiseMissile 弹头相结合。
1. 建筑类: Building_CatastropheMissileSilo.cs
路径: Source/ArachnaeSwarm/Buildings/Building_CatastropheMissileSilo.cs
功能: 这是导弹发射井的建筑本体，负责处理玩家的瞄准指令。它几乎是 Building_Railgun 的翻版，但进行了一些重命名和命名空间调整。

}
}
2. 动作类: Verb_LaunchCatastropheMissile.cs
路径: Source/ArachnaeSwarm/Verbs/Verb_LaunchCatastropheMissile.cs
功能: 定义发射动作。它会创建 WorldObject_CatastropheMissile 并将其发射到世界地图。
using RimWorld;
using RimWorld.Planet;
using UnityEngine;
using Verse;
namespace ArachnaeSwarm
{
public class Verb_LaunchCatastropheMissile : Verb_Shoot
{
public override bool CanHitTargetFrom(IntVec3 root, LocalTargetInfo targ)

}

if (silo == null || !silo.LongTarget.IsValid) return false;
WorldObject_CatastropheMissile missile = (WorldObject_CatastropheMissile)WorldObjectMaker.MakeWorldObject(
DefDatabase<WorldObjectDef>.GetNamed("CatastropheMissile_Flying")
);
missile.Tile = silo.Map.Tile;
missile.destinationTile = silo.LongTarget.Tile;
missile.destinationCell = silo.LongTarget.Cell;
missile.Projectile = this.verbProps.defaultProjectile;
Find.WorldObjects.Add(missile);
// Consume fuel
silo.refuelableComp.ConsumeFuel(silo.refuelableComp.Props.fuelConsumptionRate);
// Visual/Sound effects at launch site
MoteMaker.MakeStaticMote(silo.TrueCenter(), silo.Map, ThingDefOf.Mote_ExplosionFlash, 10f);
SoundDefOf.RocketLaunch.PlayOneShot(new TargetInfo(silo.Position, silo.Map));
return true;
}
}
}
3. 飞行物类: WorldObject_CatastropheMissile.cs
路径: Source/ArachnaeSwarm/World/WorldObject_CatastropheMissile.cs
功能: 模拟导弹在世界地图上的飞行，并在抵达时生成 Projectile_CruiseMissile。
using RimWorld.Planet;
using UnityEngine;
using Verse;
using RimWorld;
namespace ArachnaeSwarm
{
public class WorldObject_CatastropheMissile : WorldObject
{
public int destinationTile = -1;
public IntVec3 destinationCell = IntVec3.Invalid;
public ThingDef Projectile;
private int initialTile = -1;
private float traveledPct;
private const float TravelSpeed = 0.0002f; // Faster than sabot
public override void ExposeData()
{
base.ExposeData();
Scribe_Values.Look(ref destinationTile, "destinationTile", 0);
Scribe_Values.Look(ref destinationCell, "destinationCell");
Scribe_Defs.Look(ref Projectile, "Projectile");
Scribe_Values.Look(ref initialTile, "initialTile", 0);
Scribe_Values.Look(ref traveledPct, "traveledPct", 0f);
}
public override void PostAdd()
{
base.PostAdd();
this.initialTile = this.Tile;
}
private Vector3 StartPos => Find.WorldGrid.GetTileCenter(this.initialTile);
private Vector3 EndPos => Find.WorldGrid.GetTileCenter(this.destinationTile);
public override Vector3 DrawPos => Vector3.Slerp(StartPos, EndPos, traveledPct);
public override void Tick()
{
base.Tick();
traveledPct += TravelSpeed / GenMath.SphericalDistance(StartPos.normalized, EndPos.normalized);
if (traveledPct >= 1f)
{
Arrived();
}
}
private void Arrived()
{
Map targetMap = Current.Game.FindMap(this.destinationTile);
if (targetMap != null)
{
// Target is a loaded map, spawn the projectile to hit it
IntVec3 entryCell = Find.WorldGrid.GetRotatedPos(new IntVec2(0, 1), targetMap.info.parent.Rotation).ToIntVec3() * (targetMap.Size.x / 2);
entryCell.y = 0;
entryCell.z += targetMap.Size.z / 2;
Projectile_CruiseMissile missile = (Projectile_CruiseMissile)GenSpawn.Spawn(this.Projectile, entryCell, targetMap, WipeMode.Vanish);
missile.Launch(this, this.destinationCell, this.destinationCell, ProjectileHitFlags.IntendedTarget);
}
else
{
// Target is not a loaded map (e.g., caravan, site), do direct damage
GenExplosion.DoExplosion(
this.destinationCell,
null, // No map
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customExplosionRadius ?? 5f,
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customDamageDef ?? DamageDefOf.Bomb,
null, // Launcher
this.Projectile.GetModExtension<CruiseMissileProperties>()?.customDamageAmount ?? 50
);
}
Find.WorldObjects.Remove(this);
}
}
}
