Linedef type 544, Current, is a type of linedef special which creates a horizontal current on every tagged sector that carries players and pushable Objects. It is usually applied to water blocks, and is frequently used in Deep Sea Zone to create waterslides.


The target sector must have either the Wind/Current or the Ice/Sludge and Wind/Current sector effect for this special to work. The speed of the current is determined by the length of the control linedef. The direction of the current is determined by the direction of the controlling linedef.

If the Solid Midtexture flag is checked, the current will be used as a waterslide. In this situation, it will force players into their pain sprites and make them unable to slow down or speed up. If the Not Climbable flag is checked, the pushing effect is made exclusive – once an Object has been pushed by this effect, it cannot be pushed by any other pushing or carrying effect in the same tic. This is useful if the effect is applied to multiple adjacent sectors, since it would normally be applied twice when an Object crosses the border between two sectors with the effect.
