Linedef type 320

From SRB2 Wiki
Jump to: navigation, search

Linedef type 320, Unlockable – Once, is a type of linedef executor trigger which activates any linedef executor in the control sector if a certain unlockable has been unlocked beforehand. Note that this linedef has no effect in netgames, or if gamedata is no longer being saved due to the use of a protected console command (such as god or devmode). The linedef executor will trigger only the first time, and then will not be triggered again until the map is reloaded.

Setup

The front texture X offset determines the number of the unlockable to check for, ranging from 0 to 31.

Sample

Example WAD: ex_ld320_trigger_unlockableonce.wad
  • This example WAD can be played in any gametype. It uses MAP01, replacing Greenflower Zone Act 1.
  • Stepping on the red button will unlock the Sound Test unlockable. Afterwards, stepping on the blue button will give the player 100 points. Note that the gamedata is saved, so once you have pressed the red button in one game session, in every following game session the Sound Test unlockable will already be unlocked and the blue button will work immediately. To reset the unlockable, delete the file ld320_test.dat in your SRB2 folder.
