Name it "Modules". - Place the following module scripts inside ReplicatedStorage.Modules: - VRHead.lua (Contents from replicated/Modules/VRHead.lua) - VRHand.lua (Contents from replicated/Modules/VRHand.lua) - IK.lua (Contents from replicated/Modules/IK.lua) 3) RemoteEvent: - The server script will create a RemoteEvent named "VRTrackingEvent" automatically under ReplicatedStorage if missing. - You can pre-create it: Right-click ReplicatedStorage -> Insert Object -> RemoteEvent -> Rename to "VRTrackingEvent" 4) Scripts placement: - StarterPlayer -> StarterPlayerScripts: - Add a LocalScript named "VRClient" with contents from StarterPlayerScripts/VRClient.lua - StarterPlayer -> StarterCharacterScripts: - Add a LocalScript named "VRCharacter" with contents from StarterCharacterScripts/VRCharacter.lua - ServerScriptService: - Add a Script named "VRServer" with contents from ServerScriptService/VRServer.lua 5) Game Settings and Testing: - Use "Play" (local) or "Start" with multiple players to test replication. - For VR testing: - Use an HMD (Oculus, Index, etc.) and enable VR in Studio (Device > VR). Or use the "VR Emulation" plugin for Studio testing. - Ensure the player is wearing an R6 avatar (or the server-side joint names may differ). 6) Permissions: - The modules assume standard APIs: VRService, UserInputService, RunService. No special permissions are required. 7) Troubleshooting: - If joints snap back, check that other scripts are not overriding Motor6D.C0/C1. - If avatars are R15, joint names differ and some motor names will not match; for R15 you need a different mapping (this package targets R6). 8) Recommended extras: - Add smoothing interpolation if motion is jittery. - Add hand model attachments (Accessory arms or tools) parented to character parts and driven by pose data for better visuals. 9) Safety: - Server rate-limits basic messages. For production, add authentication, distance checks, and bandwidth optimizations. Save this README inside the 'replicated/Modules' or help folder for quick reference. R6 VR System — Exact Setup Steps 1. Project requirements - Roblox Studio (latest) - Test device: VR headset recommended (Oculus, Index, etc.) - Avatar type: R6 (set in Game Settings -> Avatar -> Avatar Type) 2. Create folder structure (in Explorer) - ReplicatedStorage - Modules (folder) - VRHead (ModuleScript) -> paste replicated/Modules/VRHead.lua contents - VRHand (ModuleScript) -> paste replicated/Modules/VRHand.lua contents - IK (ModuleScript) -> paste replicated/Modules/IK.lua contents - ReplicatedStorage - (optional) RemoteEvent -> name it "VRTrackingEvent" (server creates automatically if missing) - StarterPlayer - StarterPlayerScripts - VRClient (LocalScript) -> paste StarterPlayerScripts/VRClient.lua contents - StarterCharacterScripts - VRCharacter (LocalScript) -> paste StarterCharacterScripts/VRCharacter.lua contents - ServerScriptService - VRServer (Script) -> paste ServerScriptService/VRServer.lua contents 3. Publishing & Testing - Save & publish place to roblox to test with multiple players if needed. - Press Play (Local) to test single player behavior. - For VR headset testing: Start Play, then enable VR Device -> Enter VR through device. 4. Notes on R6 specifics - R6 joint names used: - Torso - Head - Right Shoulder - Left Shoulder - Neck (Motor6D under torso) - If your experience forces R15, the system will not map correctly; convert to R6 or adapt Motor6D names. 5. How the system works (overview) - ClientLocalScript reads VRService for head/hand CFrames and starts local mapping modules to mutate Motor6Ds on the player's character. - The client sends tracking poses to the server RemoteEvent at up to ~30Hz. - Server relays received poses to all clients; clients apply remote players' poses for visualization. 6. Optional improvements - Add interpolation/blending curve adjustments. - Add per-player smoothing settings. - Add deadzone thresholds to reduce micro-jitter. - Add crouch/step locomotion mapping to Humanoid for physical movement. Follow these steps exactly to set up the R6 VR system in your place. Controls, testing tips, and debugging checklist Controls (testing without headset) - Press 'V' in the current implementation to reference toggling instructions. Note: VR toggling programmatically is limited in Studio. - Use VR Emulation plugin (Roblox) to simulate headset and controllers in Studio. Testing tips 1. Ensure Avatar Type = R6 in Game Settings before placing modules/scripts. 2. Start Play (Local) and confirm no errors in the Output window. 3. Put print statements temporarily in StarterPlayerScripts/VRClient.lua to verify character added and VRService state. 4. If avatars look distorted when remote, confirm the RemoteEvent is firing and clients receive packet (add prints in VRCharacter.lua). 5. For movement tracking, the system currently maps head relative to torso. You can optionally set HumanoidRootPart.CFrame using head offset for locomotion (be careful with physics). Common issues & fixes - Motor6D reset each frame: > Another script or engine replication may be writing to C0/C1. Search for other scripts that touch joints. - No RemoteEvent found: > Server creates it automatically; ensure ReplicatedStorage is accessible. - Hand/Head jitter: > Increase smoothing in the modules (adjust lerp alpha) or lower network send rate. - R15 players visible: > The modules are R6-specific. Convert avatars to R6 or add R15 mappings. Performance - Keep client send rate ~20-30Hz to balance smoothness vs. network. - Compress data when scaling up (e.g., quantize rotations/positions). When asking for help: - Include Output errors, exact steps you followed, and whether you're testing in Studio or a live client with a headset. FAQ — R6 VR System Q: Will this work with R15? A: Not directly. R15 uses different joints and attachments. You will need to adapt joint names and attachment/motor mappings. Q: Can this move the player's root position (locomotion)? A: The basic system maps head/hand poses. Adding natural locomotion (walking from VR movement) requires careful network and anti-cheat handling. If you want room-scale movement, map head offset -> Humanoid.RootPart movement locally and inform the server. Q: Is this optimized for multiplayer? A: This implementation is a starting point. For production, add delta compression, authority checks, and interpolation on remote clients. Q: Is head and hand CFrame secure? A: Clients provide their own tracking; for competitive games consider server-side validation or limits (distance, speed caps). If you need an R15 version or added features (teleport locomotion, gesture recognition, weapon aim mapping), ask and specify which features to implement.
