What Are SA-MP Filterscripts?

Filterscripts are standalone Pawn scripts that run alongside your main gamemode — they don't replace it. Think of them as plug-and-play modules that add specific features: admin panels, anti-cheat systems, mini-games, or UI enhancements. They're loaded in server.cfg under the filterscripts line and can be added or removed without touching your main gamemode.

Why Use Filterscripts?

  • Modularity — Keep your gamemode clean by offloading features to separate scripts.
  • Easy Updates — Update or swap a filterscript without recompiling your entire gamemode.
  • Community Resources — Thousands of free filterscripts are available on the SA-MP forums and GitHub.
  • Rapid Development — Add major features in minutes rather than coding them from scratch.

Categories of Essential Filterscripts

1. Admin Systems

A good admin filterscript lets you manage players in real time — kick, ban, mute, teleport, and more. Look for scripts that support admin levels, so junior moderators have fewer privileges than senior admins. Popular choices in the community include ZCMD-based admin scripts that use fast command processing.

2. Anti-Cheat Plugins

Cheating is a persistent problem in SA-MP. Anti-cheat filterscripts detect common hacks such as speed hacks, teleport hacks, and weapon hacks by validating player positions and states server-side. Some well-regarded options rely on SA-MP's built-in callbacks like OnPlayerUpdate to check for suspicious behaviour every tick.

3. Speedometer & HUD Overlays

Visual HUDs showing speed, health, and fuel add immersion — especially for roleplay and racing servers. These filterscripts use TextDraws to render custom UI elements on the player's screen without any client-side mod required.

4. Animated Gates & Doors

Moving objects are handled server-side via MoveObject. Gate filterscripts let you define zones where objects open automatically when a player approaches — great for base entrances or garages.

5. Weapon Shop Systems

Weapon shop filterscripts create interactive pickup-based menus allowing players to buy weapons with in-game currency. They're highly configurable and pair well with economy gamemodes.

How to Install a Filterscript

  1. Place the compiled .amx file in your server's /filterscripts/ folder.
  2. Open server.cfg and locate the filterscripts line.
  3. Add the script name (without extension): filterscripts adminscript anticheat speedometer
  4. Restart the server. Filterscripts load in the order listed.

Compatibility Tips

  • Always check the SA-MP version the filterscript was designed for.
  • Avoid multiple filterscripts that hook the same callback without using y_hooks or ALS (Advanced Library System) — conflicts will cause unexpected behaviour.
  • Test each filterscript individually before combining them in production.

Where to Find Filterscripts

The SA-MP Community Forums (specifically the Filterscripts section) and GitHub are the best places to find regularly maintained scripts. Always review source code before deploying anything on a live server to ensure there are no backdoors or malicious entries.
