4. Template entities

MESS contains a small library of so-called 'template entities'. These let you manage complex entity setups with just a single entity.

For example, a common trick for triggering a random target involves an env_beam surrounded by multiple func_buttons. Instead of placing all these entities manually, you can place a single mtl_trigger_random, and let MESS generate the beam and buttons for you when you compile your map.

Generic template entities

• mtl_env_model -- for placing small prop models.
• mtl_trigger_area -- triggers specific targets when a player enters, stays in or leaves an area.
• mtl_trigger_counter -- a multi-target variant of game_counter. Also has a clock mode.
• mtl_trigger_periodic -- triggers its target periodically.
• mtl_trigger_random -- triggers a random target. Also has a continuous mode.
• mtl_trigger_sequence -- an advanced variant of multi_manager. Supports looping.

Counter-Strike template entities

• cs_trigger_roundstart -- for triggering a target when a new round starts.
