Technical Electronics & Automation

Wiremod is arguably the most complex and functionally powerful modification within the Garry’s Mod ecosystem. It empowers your community to architect functional computers, automated defensive turrets, and intricate navigation systems using a vast array of electronic components. However, its specialized “Expression 2” (E2) scripting environment can be inadvertently or maliciously misused to trigger significant server-wide lag or kernel-level crashes. This guide ensures you can provide the depth of Wiremod while maintaining absolute server stability.

​
Step 1: Installation & Verification

Follow these steps to initialize the Wiremod framework on your server.
1

Workshop Deployment

Add the primary Wiremod addon to your server’s Steam Workshop Collection.
2

Initialize the Hook

Restart your server via the Game Panel to mount the new assets.
3

Technical Audit

Join the server and verify that the “Wire” tab has successfully initialized within your “Q” spawn menu.

​
Step 2: Strategic Stability Configuration

To prevent players from executing unoptimized E2 logic that consumes excessive CPU cycles, you must establish strict operational quotas.
1

Access Expression 2 Settings

While in-game, open your Spawn Menu (Q), navigate to the Utilities tab, and select Wire -> Expression 2.
2

Configure CPU Quotas

Adjust the following variables to enforce processing limits:
  • Soft Quota: Set to 2000. (Triggers a warning if exceeded).
  • Hard Quota: Set to 8000. (Instantly disables the chip if exceeded).
3

Restrict Extensions

For security integrity, ensure the http and console extensions are Disabled. This prevents malicious actors from using your server node to launch outbound DDoS attacks or flooding your console logs with irrelevant data.

​
Step 3: Administrative Tool Restrictions

If your community requires a higher level of oversight, we recommend restricting the “Expression 2” tool to verified groups (e.g., VIPs or Staff) using the ULX framework.
1

Open ULX Menu

Type !menu in the in-game chat.
2

Navigate to Sandbox Tools

Go to the Cmds tab and select Sandbox -> Tool Restrictions.
3

Enforce Authority

Locate wire_expression2 in the list and restrict its usage to the supporter group or higher. This ensures that only trusted participants can use the most resource-intensive capabilities of the mod.
