- Genre: Battle Royale
- Expert blueprint for Battle Royale games with zone mechanics, large-scale networking, and survival gameplay.
- NEVER Do
- NEVER sync all 100 players every frame
- — Use relevancy system: only sync players within visual range. Far players update at 4Hz, nearby at 20Hz+.
- NEVER make zone center fully random
- — New circle must overlap significantly with old circle, or players teleport. Limit offset to
- current_radius - target_radius
- .
- NEVER use client-side hit detection
- — Client says "I shot at direction X", Server validates "Did it hit?". Prevents cheating.
- NEVER spawn loot without pooling
- — 1000+ loot items cause GC spikes. Pool loot pickups and reuse instances.
- NEVER forget VisibilityNotifier3D for distant players
- — Disable
- _process()
- and AnimationPlayer for players behind or far away. Saves 60-80% CPU.
- Available Scripts
- MANDATORY
-
- Read the appropriate script before implementing the corresponding pattern.
- kill_feed_bus.gd
- Global elimination signal bus with match stat tracking. Single emission point for UI/logging, sorted killer rankings for end-game summary.
- storm_system.gd
- Dynamic zone shrinking with damage interpolation. Tweens center/radius smoothly, scales damage by zone size for end-game intensity.
- Core Loop
- Deploy
-
- Player chooses a landing spot from an air vehicle.
- Loot
-
- Player scavenges weapons and armor.
- Move
-
- Player runs to the safe zone to avoid taking damage.
- Engage
-
- Player fights others they encounter.
- Survive
- Player attempts to be the last one standing. Skill Chain Phase Skills Purpose 1. Net godot-multiplayer-networking Authoritative server, lag compensation 2.

- Networking Optimization
- You cannot sync 100 players every frame.
- Relevancy
-
- Only send updates for players within visual range.
- Frequency
-
- Update far-away players at 4Hz, nearby at 20Hz+ (Server Tick).
- Snapshot Interpolation
-
- Client buffers headers to play them back smoothly.
- Godot-Specific Tips
- MultiplayerSynchronizer
-
- Use
- replication_interval
- to lower bandwidth for distant objects.
- VisibilityNotifier3D
-
- Critical. Disable
- _process
- and AnimationPlayer for players behind you or far away.
- Occlusion Culling
-
- Essential for large maps with buildings. Bake occlusion data.
- HLOD
-
- Use Hierarchical Level of Detail for terrain and large structures.
- Common Pitfalls
- Too Main Loot
-
- Too much loot causes lag.
- Fix
-
- Use object pooling for loot pickups.
- Camping
-
- Players hide forever.
- Fix
-
- The Zone forces movement. Also, anti-camping mechanics like "scan reveals" (optional).
- Cheating
-
- Client-side hit detection.
- Fix
- Authoritative server logic. Client says "I shot at direction X", Server calculates "Did it hit?". Reference Master Skill: godot-master
