1. Getting started

MESS (Macro Entity Scripting System) is a map compile tool that gives Half-Life level designers the following tools:

• A template instancing system that can be used in a variety of ways, such as for decorating terrain or for generating repetitive entity setups.
• Multiple template entities and template behaviors that can greatly simplify complicated entity setups, such as triggering random targets.
• A scripting language that can be used for additional randomization and customization, or for creating custom template entities and behaviors.
• Conversion between different map formats, which can be used for migrating between level editors or for automating .map exports.

To get started, download MESS 1.2.3 and follow the J.A.C.K. & Hammer setup guide or the Trenchbroom setup guide.
