Lab Host

6 ANSWERS

How do I fix "Content-Length not available" in Unity?

This error occurs when a file server doesn't send the file size to the game engine. Using our Lab Host tool automatically fixes this by injecting the necessary headers and forcing correct MIME types — so your audio or textures play perfectly every time.

How do I use multiplayer links?

After uploading your file to Lab Host, copy the generated link and paste it directly into the relevant field in-game (like a radio URL or custom texture path). The link is globally accessible and CORS-enabled, so everyone in your server can use it seamlessly.

Does it support Dropbox?

Yes! Our tool automatically detects Dropbox links and converts them to direct streaming URLs, bypassing the preview page and making them fully compatible with the game's audio and texture systems.

What is the Worker Proxy?

The Worker Proxy is a specialized server-side script that acts as a middleman. It fetches files from restrictive servers (like those with CORS issues) and serves them with the correct MIME types and headers required by Unity.

Does it support Arabic text?

Yes! We have integrated Arabic Fixer support. If you're hosting text-based resources or generating Arabic strings, our platform ensures they're formatted correctly for the game engine.

Is the hosting secure?

We prioritize privacy. Files are uploaded anonymously and we do not collect personal data. However, any hosted file becomes publicly accessible via its link — so avoid hosting private or sensitive content.

Do Lab Host links expire?

By default, links remain active indefinitely. However, you can choose to set an Expiration Duration (from 1 day up to 30 days) during the upload process. Expired links are automatically purged to help keep your project data clean and manageable.

Triggerbox Builder

4 ANSWERS

What is the difference between Sync modes?

Global Sync: The action fires for every player in the server simultaneously — essential for doors, gates, and shared world events.
Local Sync: The action only fires for the player who triggered it — ideal for personal messages or private UI effects.

How do cooldowns work?

Cooldowns prevent a Triggerbox from being activated too frequently. This is essential for preventing spam and maintaining server performance, especially for physics-heavy or audio actions.

How do I add background music (BGM)?

Use the PlayAudio action in the Builder. For background music, ensure you have a direct URL (use Lab Host if needed) and enable the Loop parameter to keep the music playing indefinitely.

How do I fix broken Triggerbox code?

Broken code is usually caused by syntax errors (missing brackets or quotes) or logic loops. Use our Quick Builder to generate clean code, then test one action at a time to isolate the issue.

Map Editor & Spatial Toolkit

5 ANSWERS

How do I merge objects?

Merging is done through the Map Editor's optimization tools. Select the objects you want to group and use the Merge function to create a single mesh — this significantly improves in-game performance.

How do I fix coordinates using Spatial Toolkit?

If your map looks shifted or objects are out of place, use the Spatial Toolkit's coordinate fixing feature. It recalculates origin points to ensure perfect alignment with the LAC world grid.

Why are some objects invisible?

Invisible objects are often caused by renderer errors or Backface Culling. Ensure your meshes have outward-facing normals and that you haven't exceeded the game's material limit for a single scene.

Are there object limits?

While there's no hard cap, performance degrades after a few thousand objects. We recommend keeping maps optimized and using Merging for repetitive structures like buildings or fences.

What is the Map Fixer Tool?

The Map Fixer is a surgical recovery tool designed to repair corrupted map headers and patch texture references. If your map fails to load or has missing textures after an update, the Fixer can often restore it to full functionality.

How do I use the Map Role Editor?

The Role Editor allows you to define spatial zones that assign specific roles (like Admin, VIP, or Mechanic) to players. It's a powerful tool for setting up automated permissions and interactive Roleplay elements within your custom maps.

Slash Commands

4 ANSWERS

How do I use slash commands?

Open the in-game chat and type a forward slash followed by the command (e.g., /time set 1200). Commands are context-sensitive and some require specific roles like Admin.

Are there command limits?

Most servers have Anti-Spam protections — rapidly typing commands may result in a temporary chat mute. Some commands also have character limits on their parameters.

What are some common commands?

/tp [player] — Teleport to a player.
/v [id] — Spawn a vehicle.
/clear — Clear your chat history.
/role [id] [role] — Assign a role like Admin or Mechanic.

Browse the full list in our Slash Commands Documentation.

Are commands compatible with every server?

Basic commands work on most servers, but custom commands are only available if the host has configured them or is running a specific version of the game.

General Game FAQ

11 ANSWERS

How do I share my maps or import new ones?

You can share and download maps through the Community tab in-game.

Your created maps are saved at:
/Android/data/com.MA.LAC/files/editor

To manage files:

Use ZArchiver to access the folder.
On Android 11+, direct access is restricted. Open ZArchiver → Menu → Settings → ROOT → Set Root access type to Shizuku/SUI, then enable ADB wireless debugging.

To import quickly: Paste the map link in the Map Name field inside the LAC Editor tab and press Create — it auto-downloads and loads the map.

Always back up your map files before editing or replacing them!

How do I pair my PS4 Bluetooth controller?

Turn on Bluetooth on your device.
Press and hold Share + PS buttons until the light bar flashes rapidly.
Select the controller in your device's Bluetooth list. If prompted, enter PIN: 0000.

Only PS4 controllers are officially supported. Other Bluetooth controllers may work but are not guaranteed.

Why does audio disappear when I switch apps and come back?

This is a known Unity Engine bug affecting Bluetooth audio devices only. To fix it:

Disconnect and reconnect your Bluetooth headset/headphones.
Or simply restart the game.

Avoid switching apps while using Bluetooth audio. This issue does not affect wired or built-in speakers.

Why am I being kicked with messages like "The server might be full"?

These are generic disconnect messages that don't always reflect the real reason. Common causes:

Unstable or laggy internet connection.
The server crashed or restarted.
High ping or packet loss.

Fixes: Restart the game and router, rejoin after a few minutes, or switch to a more stable connection. Avoid VPNs and mobile hotspots.

Fun Fact: Messages like "The server might be dead x_x" come from a preset list — the message is rarely the actual cause.

What does "Cannot resolve destination host" mean?

The game can't reach the server — it can't translate the server address into an IP. Possible causes:

You're not connected to the internet.
Your network or router is blocking the game.
DNS issues preventing server address resolution.

How to fix:

Verify your internet is active and restart your router.
Switch between Wi-Fi and mobile data.
Try a VPN if on a restricted network (school/work).
Change DNS to 8.8.8.8 / 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare).

How do I play Los Angeles Crimes online with friends?

Same Wi-Fi (LAN):

Host launches any map in LAC.
Find the host's local IP via Wi-Fi Settings → Advanced → IP Address (e.g. 192.168.x.x).
Friends go to the LAN tab, enter the IP, and click Connect.

Different networks (Remote Play):

Port forward your router: Port 7777, Protocol UDP (UPNP must be enabled).
Find your public IP at whatismyipaddress.com and share it with friends.
Or use Interaction Menu → Server Options → Share-Server and friends join from the Community Tab.

If it doesn't work: restart Wi-Fi & game, disable your firewall temporarily, or check if your router supports UPNP.

How do I host a server on Linux (VPS)?

Download the Linux version from the official website's Download Releases section and select LAC. Review the #README.txt file included for setup instructions.

For a step-by-step walkthrough, watch the tutorial on the 3M YouTube Channel.

A VPS-hosted server runs 24/7, giving your community a persistent world without keeping your phone on.

What are the Cellphone Cheat Codes?

Enter these numbers in your in-game phone to trigger hidden effects:

1999756966	Slow Motion
19993562837	Moon Gravity
666	Something... feathery?
999	Brings back a ring from the past...

Dial at your own risk. Some numbers do things. Some don't. Some were added just for laughs.

Why can't my friends spawn a helicopter in my server?

Helicopters are restricted to Admin or Mechanic roles for performance optimization. Assign a role with:

/role [id] mechanic

Find the player ID in the Pause Menu. Example: /role 3 mechanic

Helicopters are more resource-intensive than cars and can cause lag, which is why they're restricted by default.

How do I reduce lag and optimize game performance in LAC?

If you are experiencing lag or framerate drops, try these optimization steps:

Adjust Settings: Go to settings and disable shadows and other high-cost visual effects.
Turn off Reflections: Disable reflections entirely by typing /reflections 0 in the chat.
Manage Traffic: Reduce or disable city traffic under Settings > Game > Traffic.
Minimize Physical Objects: Avoid spawning excessive dynamic physical objects like tires, cones, doors, and burgers.
Spread Out Map Objects: Keep editor objects under 5,000 and distribute them across the map so that the chunk-loading system can cull distant objects effectively.
Tune View Distance: Adjust the object rendering distance using /chunkload <distance> (e.g. /chunkload 500 for 500m view distance).

Note: Older mobile devices equipped with Mali GPUs generally struggle to run complex Unity-based games. Keep your custom maps lightweight if targeting these devices.

Is there a limit to the number of items in my inventory?

Yes, there is a hard inventory limit of 32 items in Los Angeles Crimes. Be sure to check item counts and prune unnecessary items using the inventory commands to stay within this limit.
