96 - Trigger_If (If)


Evaluates a Lua expression and triggers when it is true. The Lua evaluation runs in the same Lua space as all other Lua scripts (map scripts and server scripts) so you can use functions and variables from these scripts.

Sample 1: Always trigger

Sample 2: Never trigger

Sample 3: Only trigger if the Lua variable "sample" has the value 5

Sample 4: Only trigger if the Lua variable "sample" has a value between 3 and 7 (4,5,6)
sample>3 and sample<7

Sample 5: Only trigger if there is a player with ID 1 on the server

Attention: The server setting mp_luamap must be 1 to make this work.
Attention: This entity can be abused to execute malicious Lua code. For this reason mp_luamap is set to 0 by default!
