|
|
|
|
[← Previous: Part 9 (C++) - Polish & Debug Features](part-9-cpp-polish.md) | [Back to Index](README.md)
|

|
|
|
|
## Overview
|
|
|
|
Polish the game with visual assets, materials, and final tweaks.
|
|
|
|
**Time:** ~15 minutes
|
|
|
|

|
|
|
|
## Step 9.1: Assign Better Visuals to Blueprints
|
|
|
|
Now we use Blueprints for what they're good at: assigning visual assets!
|
|
|
|
### BP_Player:
|
|
|
|
1. Open `BP_Player`
|
|
2. Select `ShipMesh` component
|
|
3. In Details:
|
|
- **Static Mesh** → Keep Cone or choose a spaceship model
|
|
- **Material** → Create or assign a green emissive material
|
|
4. Compile and Save
|
|
|
|
### BP_Enemy:
|
|
|
|
1. Open `BP_Enemy`
|
|
2. Select `MeshComp` component
|
|
3. In Details:
|
|
- **Static Mesh** → Keep Cube or choose enemy model
|
|
- **Material** → Create or assign a red emissive material
|
|
4. Compile and Save
|
|
|
|
### BP_Bullet (if you created one):
|
|
|
|
1. Same process - assign materials for player (green) vs enemy (red) bullets
|
|
|
|
---
|
|
|
|
## Step 9.2: Create Background
|
|
|
|
1. In level, add **Plane** (from Place Actors → Basic → Plane)
|
|
2. Scale it large (Scale: 50, 50, 1)
|
|
3. Position below player (Z: -100)
|
|
4. Assign dark material (black or dark blue)
|
|
5. This provides contrast for bullets and enemies
|
|
|

|
|
|
|
## Step 9.3: Adjust Camera
|
|
|
|
If camera needs adjustment:
|
|
|
|
1. Select BP_Player in level
|
|
2. Find `SpringArm` component
|
|
3. Adjust:
|
|
- **Target Arm Length** - Higher = further away camera
|
|
- **Socket Offset** - Adjust view position
|
|
|

|
|
|
|
## Step 9.4: Final Testing
|
|
|
|
Press Play and verify:
|
|
|
|
**Gameplay:**
|
|
- ✅ Player moves smoothly with WASD
|
|
- ✅ Player fires green bullets in spread pattern
|
|
- ✅ Enemies spawn from top
|
|
- ✅ Enemies move in sine wave pattern
|
|
- ✅ Enemies fire red bullet bursts
|
|
- ✅ Collision detection works (bullets hit enemies, enemies hit player)
|
|
- ✅ Score increases when enemies destroyed
|
|
- ✅ Lives decrease when hit
|
|
- ✅ Special ability clears screen (X key)
|
|
- ✅ Timer counts down
|
|
- ✅ Victory after 300 seconds
|
|
- ✅ Game over if lives reach 0
|
|
|
|
**Visual Polish:**
|
|
- ✅ Player and enemies have distinct colors
|
|
- ✅ Bullets are visible and distinguishable
|
|
- ✅ UI is readable
|
|
- ✅ Background provides good contrast
|
|
|
|
**Performance:**
|
|
- ✅ 60 FPS with 100+ bullets on screen
|
|
- ✅ No lag or stuttering
|
|

## Step 9.5: Build Standalone Game (Optional)
|
|
|
|
To build a playable executable:
|
|
|
|
**First, set the default level:**
|
|
|
|
1. **Edit → Project Settings**
|
|
2. In the left panel, find **Project → Maps & Modes**
|
|
3. Under **Default Maps**:
|
|
- **Editor Startup Map** → Select `BulletHellLevel`
|
|
- **Game Default Map** → Select `BulletHellLevel`
|
|
4. Close Project Settings
|
|
|
|
**Then package the game:**
|
|
|
|
1. In the main toolbar, click **Platforms** (next to the Play button)
|
|
2. Select **Windows** (or **Linux**)
|
|
3. Click **Package Project**
|
|
4. Choose output folder
|
|
5. Wait for build (5-10 minutes)
|
|
6. Run the `.exe` file from output folder
|
|
|
|
> **Alternative:** You can also access packaging via **Edit → Project Settings → Packaging** to configure settings, then use the **Platforms** menu to build.

|
|
|
### Key Benefits Achieved
|
|
|
|
✅ **90% faster variable definition** - copy-paste vs clicking
|
|
✅ **Version control friendly** - readable C++ diffs instead of binary Blueprints
|
|
✅ **Type-safe** - compiler catches errors before runtime
|
|
✅ **IDE support** - autocomplete, refactoring, debugging
|
|
✅ **Easier to maintain** - code is documentation
|
|
✅ **Reusable** - copy C++ files to new projects instantly
|
|
|
|
### Hybrid Approach Used
|
|
|
|
- **C++ for logic** - All game mechanics, variables, algorithms
|
|
- **Blueprints for visuals** - Meshes, materials, colors
|
|
- **Best of both worlds** - Fast development + visual asset management
|
|

## What's Next?
|
|
|
|
**Extend the game:**
|
|
