顶视角射击/角色扮演游戏框架搭建

# 顶视角射击/角色扮演游戏框架搭建 ## 1. 框架基础逻辑 首先来看一段基础的逻辑代码，它处理了不同的事件类型： ```lua local bool retval; local Actor TempActor; local Vector HitLocation; local TraceHitInfo HitInfo; retval = true; if (EventType == ZoneEvent_Touch) { // Code for Setting Bot WayPoint TempActor = PickActor(TouchLocation, HitLocation, HitInfo); ProcessTouch(TempActor, HitLocation); SetHUDPawn(TempActor); } else if(EventType == ZoneEvent_Update) { } else if (EventType == ZoneEvent_UnTouch) { // Stop Firing Pawn's weapon StopFire(0); } return retval; ``` 这个代码块根据不同的事件类型执行不同的操作： - **ZoneEvent_Touch**：选择一个演员，处理触摸事件，并设置 HUD 角色。 - **ZoneEvent_Update**：当前未做处理。 - **ZoneEvent_UnTouch**：停止角色武器的射击。 ## 2. 创建角色 ### 2.1 玩家角色 玩家角色的代码如下： ```lua class PlayerPawnCh12 extends JazzPawnDamage; var bool bFollowPlayerRotation; var string CharacterName; var int Experience; ////////// Top Down View /////// simulated function bool CalcCamera( float fDeltaTime, out vector out_CamLoc, out rotator out_CamRot, out float out_FOV ) { out_CamLoc = Location; out_CamLoc.Z += CamOffsetDistance; if(!bFollowPlayerRotation) { out_CamRot.Pitch = -16384; out_CamRot.Yaw = 0; out_CamRot.Roll = 0; } else { out_CamRot.Pitch = -16384; out_CamRot.Yaw = Rotation.Yaw; out_CamRot.Roll = 0; } return true; } simulated singular event Rotator GetBaseAimRotation() { local rotator POVRot, tempRot; tempRot = Rotation; tempRot.Pitch = 0; SetRotation(tempRot); POVRot = Rotation; POVRot.Pitch = 0; return POVRot; } defaultproperties { bFollowPlayerRotation = false CamOffsetDistance= 1500.0 CharacterName = "Player" Experience = 0 } ``` 这里定义了玩家角色的一些属性和方法： - **属性**：`bFollowPlayerRotation` 决定相机是否跟随玩家旋转，`CharacterName` 是玩家名称，`Experience` 是玩家经验值。 - **方法**：`CalcCamera` 函数用于设置相机视角为顶视角，`GetBaseAimRotation` 函数设置武器射击的瞄准旋转。 ### 2.2 盟友机器人角色 盟友机器人角色的代码如下： ```lua class BotPawnCh12 extends BotPawn; var string CharacterName; var int Experience; event TakeDamage(int Damage, Controller InstigatedBy, vector HitLocation, vector Momentum, class<DamageType> DamageType, optional TraceHitInfo HitInfo, optional Actor DamageCauser) { PlaySound(JazzHitSound); Health = Health - Damage; if (Health <= 0) { SetLocation(InitialLocation); SetPhysics(PHYS_Falling); Health = 100; Experience = 0; } } defaultproperties { CharacterName = "TeamMember1" Experience = 0; } ``` 盟友机器人角色有自己的名称和经验值，`TakeDamage` 函数处理受到伤害的情况，当生命值小于等于 0 时，重置位置、物理状态、生命值和经验值。 ### 2.3 敌人机器人角色 敌人机器人角色的代码如下： ```lua class GuardPawn2 extends BotPawnCh10; var int ExperienceValue; event TakeDamage(int Damage, Controller InstigatedBy, vector HitLocation, vector Momentum, class<DamageType> DamageType, optional TraceHitInfo HitInfo, optional Actor DamageCauser) { PlaySound(HurtSound); Health = Health - Damage; if (Health <= 0) { PlaySound(DeathSound); /*Add experience points to player or member of player's group if this pawn is killed by one of them*/ if (InstigatedBy.IsA('ExampleCh12PC')) { PlayerPawnCh12(InstigatedBy.Pawn).Experience += ExperienceValue; } else if (InstigatedBy.IsA('BotAllyController')) { BotPawnCh12(InstigatedBy.Pawn).Experience += ExperienceValue; } //destroy(); SetLocation(InitialLocation); SetPhysics(PHYS_Falling ```
