Linedef type 424

Jump to: navigation, search

Linedef type 424, Change Weather, is a type of linedef executor which, when triggered, changes the weather in the level. This effect is useful for levels which use multiple environments.


The tag given to this linedef is irrelevant. The weather effect to change to is determined by the front texture X offsets of the control linedef, with the values as follows:

Value Effect
0 None
1 Storm (thunder, lightning and rain)
2 Snow
3 Rain
4 Preloaded precipitation 1
5 Storm (no rain)
6 Storm (no lightning)

1 Preloaded precipitation is used for keeping the precipitation data in memory without actually displaying any rain or snowflakes. In all versions of the game up to v2.0, a noticeable pause – around two seconds in length – would occur if the weather was changed directly between "None" and any other option. Since v2.1, this pause no longer occurs, but the option remains for backwards compatibility.

By default, this linedef executor only affects the player who activates it. If the Not Climbable flag is checked, the linedef executor will affect all players simultaneously.
