SCROLLING BACKGROUND SYSTEM

Simulate realistic train and vehicle travel using the classic "rear projection" technique from vintage films. Instead of moving your vehicle through the world, the world moves past your stationary vehicle -

creating smooth, cinematic travel experiences with optimal performance.

HOW IT WORKS

Place the ScrollingBackgroundManager in your scene, configure your objects (trees, buildings, poles, mountains), set up lanes with different speeds for parallax depth, and press Play. Objects spawn ahead of

your vehicle and scroll past the windows, creating the illusion of motion.

PERFECT FOR

- Train simulators and experiences

- Vehicle interior scenes (cars, buses, subways)

- VR travel experiences (low motion sickness)

- Cinematic sequences and cutscenes

- Endless runner backgrounds

- Museum/exhibition installations

KEY FEATURES

1. OBJECT POOLING SYSTEM

Pre-allocated object pools eliminate runtime spawning overhead. Objects are recycled efficiently with per-mesh-type pooling, avoiding expensive SetStaticMesh() calls during gameplay.

2. ASYNC MOVEMENT (MULTI-THREADED)

Movement calculations run on a separate worker thread using double-buffering to minimize lock contention. Your rendering stays smooth even with hundreds of scrolling objects.

3. MULTI-LANE PARALLAX

Create unlimited lanes at different distances and speeds. Closer lanes scroll faster, distant lanes slower - producing natural depth perception and realistic parallax effects.

4. SCENARIO PRESETS

Quick-start with 4 built-in presets:

- Countryside: 5 lanes, trees, farms, rolling hills

- City: 4 lanes, buildings, streetlights, urban density

- Mountain: 4 lanes, rocks, pines, dramatic depth

- Desert: 3 lanes, cacti, mesas, vast openness

5. BLUEPRINT FRIENDLY

Full Blueprint API for runtime control:

- SetScrollingEnabled() / SetGlobalSpeed()

- ApplyScenarioPreset() / ResetSystem()

- GetPerformanceStats() for monitoring

6. HIGHLY CONFIGURABLE

Per-lane settings: speed, width, lateral offset, height, spawn/despawn distances, object spacing, random rotation, scale variation, loop behavior, timing delays.

PERFORMANCE OPTIMIZED

- Object pooling prevents GC spikes

- Async threading offloads CPU work

- Instanced mesh support (optional)

- Configurable pool sizes per lane

- Debug visualization for tuning

EASY SETUP

1. Drag ScrollingBackgroundManager into your level

2. Add your meshes to Object Types

3. Configure lanes (or use a preset)

4. Play!
