Step 8.4: Set Up Level Components

In the level (main viewport), we need to add game actors:

1. ADD CAMERA

1. In Place Actors panel (left side, or Window → Place Actors)
2. Search for "Camera Actor"
3. Drag into viewport
4. Position camera:
   • In Details panel, under Transform:
   • Location: X=0, Y=0, Z=1000
   • Rotation: X=-90, Y=0, Z=0 (looking down)
5. Set as default camera:
   • In Details panel, find "Auto Activate for Player"
   • Check the box, set Player Index to 0

For Orthographic View:

• Click on Camera component
• In Details, set "Projection Mode" to Orthographic
• Set "Ortho Width" to 1920 (or your screen width)

2. ADD PLAYER

1. From Content Browser, drag BP_Player into level
2. Position: X=0, Y=-300, Z=0 (bottom center)

3. ADD ENEMY SPAWNER

1. Drag BP_EnemySpawner into level
2. Position: X=0, Y=500, Z=0 (top of screen)
3. In Details panel, set EnemyClass to BP_Enemy

4. ADD GAME DIRECTOR

1. Drag BP_GameDirector into level
2. Position doesn't matter (it's invisible)

5. ADD SCORE MANAGER

1. Drag BP_ScoreManager into level
2. Position doesn't matter

6. Save the level (Ctrl+S)

Expected Result in Level Viewport

• Camera actor visible at top of scene (Z=1000)
• BP_Player visible at bottom center (Y=-300)
• BP_EnemySpawner visible at top (Y=500)
• BP_GameDirector and BP_ScoreManager in Outliner (invisible actors)

Expected Result in Outliner

- CameraActor
- BP_Player
- BP_EnemySpawner
- BP_GameDirector
- BP_ScoreManager

Step 8.5: Set Default Level

1. Edit → Project Settings
2. Maps & Modes
3. Under "Default Maps":
   • Editor Startup Map: Select BulletHellLevel
   • Game Default Map: Select BulletHellLevel

Expected Result
