<cat>Dev.Map</cat> <title>Map Lua</title> Maps can run Lua scripts via the `lua_run` entity. Here's an example on `gm_construct`: <upload src="70c/8dc34c7aa6923b1.png" size="625196" name="image.png" /> During the execution of the script, the following global variables are available: ``` -- The activator of the input (i.e. the player that pressed a button or walked into the trigger) print( ACTIVATOR ) -- The called or the input (i.e. button or the trigger that sent the input to this lua_run entity) print( CALLER ) -- Will be set to the ACTIVATOR, if it is a player. print( TRIGGER_PLAYER ) ``` The code can be ran on entity spawn via a spawnflag, or via its `RunCode` input. There's also the `RunPassedCode` input, which will any code passed as the input value. There's also the `RunPassedCode` input, which will run any code passed as the input value. Never use double-quotation marks in any Hammer Output, it will corrupt the map file. Try using Double Square brackets instead.
