Linedef type 523, Carry Objects on Ceiling, is a type of linedef special which carries Objects on any tagged sector's ceiling without scrolling the ceiling flat.

Setup

The length of the linedef controls the speed of the carrying (32 fracunits of length equal one fracunit per tic). The direction of the linedef controls the direction in which the ceiling will carry Objects. The target sector must have the Conveyor Belt sector type applied to it, otherwise the carrying doesn't function properly.

If Flag [6] / Not Climbable is checked, the carrying 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. This flag should be checked when using the linedef special in conjunction with linedef type 64; otherwise the player will not stand still on the "moving sector".
