|
## Overview
|
|
|
|
Create a custom Game Mode to set the default pawn class and manage game rules.
|
|
|
|
**Time:** ~5 minutes
|
|
|
|
---
|
|
|
|
## Step 8.1: Create STGGameMode C++ Class
|
|
|
|
1. **Tools → New C++ Class**
|
|
2. Choose **"Game Mode Base"** as parent
|
|
3. Name: `STGGameMode`
|
|
4. Create Class
|
|
|
|
---
|
|
|
|
## Step 8.2: Define Game Mode
|
|
|
|
### STGGameMode.h:
|
|
|
|
```cpp
|
|
#pragma once
|
|
|
|
#include "CoreMinimal.h"
|
|
#include "GameFramework/GameModeBase.h"
|
|
#include "STGGameMode.generated.h"
|
|
|
|
UCLASS()
|
|
class BULLETHELLGAME_API ASTGGameMode : public AGameModeBase
|
|
{
|
|
GENERATED_BODY()
|
|
|
|
public:
|
|
ASTGGameMode();
|
|
};
|
|
```
|
|
|
|
### STGGameMode.cpp:
|
|
|
|
```cpp
|
|
#include "STGGameMode.h"
|
|
#include "STGPawn.h"
|
|
|
|
ASTGGameMode::ASTGGameMode()
|
|
{
|
|
// Set default pawn class to our player
|
|
DefaultPawnClass = ASTGPawn::StaticClass();
|
|
|
|
// Disable auto-possess (we'll handle spawning ourselves)
|
|
bStartPlayersAsSpectators = false;
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## Step 8.3: Set Game Mode in Project Settings
|
|
|
|
1. **Edit → Project Settings**
|
|
2. **Project → Maps & Modes**
|
|
3. Under "Default Modes":
|
|
- **Default GameMode** → Select `STGGameMode`
|
|
4. Close Project Settings
|
|
|

|
|
|
|
## Step 8.4: Test
|
|
|
|
Create a new level or use existing one:
|
|
|
|
1. **File → New Level** → Empty Level
|
|
2. Save as `BulletHellLevel`
|
|
3. Add:
|
|
- Player Start (from Place Actors panel)
|
|
- STGEnemySpawner
|
|
- STGGameDirector
|
|
- STGHUDManager
|
|
- Directional Light (for visibility)
|
|
|
|
4. Press Play
|
|
|
|
### Expected Result:
|
|
|
|
- ✅ Player automatically spawns at Player Start location
|
|
- ✅ No need to manually drag BP_Player into level
|
|
- ✅ All game systems work together
|
