Linedef type 450

Linedef type 450, Execute Linedef Executor (from Tag), is a type of linedef executor which, when triggered, activates the tagged trigger linedef. This is useful for creating an effect which repeats in an infinite loop. Be careful, though, when creating an infinite loop – if this linedef executor is not delayed, the game will keep triggering it over and over without advancing to the next tic, trapping the game in an endless loop. To avoid this scenario, add a delay to the linedef executor with at least 1 tic.

Setup

This linedef should be tagged to the desired linedef executor trigger (tagged to the actual trigger linedef, not its control sector). Note that this effect only works when tagged to either a Once or a Continuous trigger; it will not work if tagged to an Each Time trigger.

Sample

Example file: ex_ld450_executelinedefexecutorfromtag.wad (MAP01) 

• Stepping on the red button will cause the sound effect DSGBEEP to play once every second.

How to use

You may load this file into your favorite map editor, such as Zone Builder. Select MAP01 as the map to load. You may also load this file in the game: Save ex_ld450_executelinedefexecutorfromtag.wad into the addons folder of your SRB2 directory. Start SRB2, go to the Addons menu, and then select ex_ld450_executelinedefexecutorfromtag.wad. Start the game in Single Player mode. Press the Console button (~), and type in the command MAP MAP01 to access the example map. When you load this file in the game, it replaces Greenflower Zone Act 1.
