Linedef type 439
This linedef should be tagged to all linedefs whose textures should be changed. The control linedef's front side texture fields determine the new textures for both sides of the target linedef, i.e., both the front upper texture and the back upper texture of the target linedef are set to the front upper texture of the control linedef. The control linedef's back side textures do nothing.
The table below shows which of the control texture linedef's textures each texture field on the target linedef will be changed to:
|Upper texture||Middle texture||Lower texture|
|Target's front side||Front upper texture||Front middle texture||Front lower texture|
|Target's back side||Front upper texture||Front middle texture||Front lower texture|
By default, all textures on the target linedef will be changed regardless of whether textures were set in each field previously or not. If the target linedef does not have a back side, the target's back side texture fields will not be affected. If the control linedef does not have a texture set for a particular texture field, the corresponding texture fields on the target linedef will change to have no texture set as well. If Flag  / Not Climbable is checked, textures are only changed if the corresponding texture field of the target linedef already has a texture set; texture fields without a texture set will be unchanged.
