🌀 Modern Teleportation Architecture

System Overview

Modern teleportation systems require more than simple position changes. A production-ready system handles:

• Network Authority Validation - Server-authoritative with client prediction
• Collision and Safety Checks - Prevent teleporting into walls or hazards
• Visual & Audio Feedback - Professional VFX and sound integration
• Performance Optimization - Efficient validation and minimal network traffic
• Extensible Design - Support for different teleport types and conditions

🛠️ Implementation Guide

1. Teleport Component Setup

Create a dedicated AC_TeleportComponent that handles all teleportation logic:

Component Structure:

🔹 AC_TeleportComponent:
  • Variables: TeleportCooldown, MaxTeleportDistance, AllowedSurfaces
  • Functions: RequestTeleport(), ValidateTeleportLocation(), ExecuteTeleport()
  • Events: OnTeleportStarted, OnTeleportCompleted, OnTeleportFailed
  • Network: Server RPCs for validation, Multicast for VFX

Key Features:

• Cooldown Management - Prevent teleport spam
• Distance Validation - Enforce maximum teleport range
• Surface Checking - Ensure valid landing surfaces
• Network Integration - Server authority with client prediction

2. Validation System

Multi-Layer Validation

🔹 Validation Layers:
  1. Distance Check: Within allowed range
  2. Line Trace: Clear path to destination
  3. Surface Validation: Valid landing surface
  4. Hazard Detection: Avoid damage zones
  5. Permissions: Player can teleport to location

Blueprint Implementation Pattern

Input → Distance Check → Line Trace → Surface Check → Authority Validation → Execute
  │           │              │             │                │
  ▼           ▼              ▼             ▼                ▼
[Valid?]   [Clear?]      [Safe?]      [Allowed?]      [Execute Teleport]
  │           │              │             │                │
  └─── Fail ──┴──── Fail ────┴──── Fail ──┴─── Success ────┘

3. Network-Safe Implementation

Client-Server Pattern

🔹 Client Side:
  • Predictive teleport for responsiveness
  • Visual feedback immediately
  • Send server RPC for validation

🔹 Server Side:  
  • Validate all teleport parameters
  • Execute authoritative teleport
  • Broadcast result to all clients
  • Handle corrections if needed

Authority Flow

Client Request → Server Validation → Authority Execution → Client Reconciliation
      │                 │                    │                     │
      ▼                 ▼                    ▼                     ▼
  [Predict Move]   [Validate All]    [Execute on Server]   [Correct if Needed]

4. Visual Effects Integration

Professional VFX Pattern

🔹 Teleport VFX Sequence:
  1. Pre-Teleport: Charge-up effect at origin
  2. During Teleport: Trail/portal effect
  3. Post-Teleport: Landing effect at destination
  4. Audio: Spatial sound with doppler effect

Niagara System Integration

🔹 VFX Components:
  • NS_TeleportCharge: Build-up effect
  • NS_TeleportTrail: Movement visualization
  • NS_TeleportLanding: Destination impact
  • Audio: 3D positioned sound cues

5. Performance Optimization

Efficient Validation

• Cached Line Traces - Reuse recent validation results
• LOD-Based Validation - Reduce check complexity at distance
• Batch Processing - Group multiple teleport requests
• Object Pooling - Reuse VFX components

Memory Management

🔹 Performance Patterns:
  • Pool VFX components instead of spawning
  • Cache frequent teleport destinations
  • Use async line traces for validation
  • Implement teleport request queuing

⚠️ Common Pitfalls & Solutions

Network Desynchronization

Problem: Client and server positions don't match after teleport Solution: Implement client reconciliation and server correction patterns

Teleporting into Geometry

Problem: Players teleport inside walls or objects Solution: Multi-point validation with collision capsule testing

Performance Issues

Problem: Expensive validation causes frame drops Solution: Async validation with result caching and LOD-based checks

VFX Spam

Problem: Multiple teleports create overwhelming visual noise Solution: VFX pooling with smart effect management and interruption
