Linedef type 425, Change Object State, is a type of linedef executor which, when triggered, changes the animation state of the activating Object. It has no effect when used on players.
Setup
The tag given to this linedef is irrelevant. The name of the Object state to change to should be written in the control linedef's front upper texture field, e.g. S_NULL. If the name is longer than eight characters, it continues in the front middle texture and front lower texture fields.
