Linedef type 547

An example of a push effect.

Linedef type 547, Push/Pull, is a type of linedef special which creates either a gravitational push or pull effect within a specified sector. Nearby players will be affected.

Setup

This special requires three elements to function correctly: a control linedef, a target sector, as well as a Thing that determines the effect of this special. Tag a linedef with linedef type 547 on a control sector to a target sector . Inside the target sector, preferably in the center, place either a Push Point or a Pull Point. To create multiple point pushers/pullers, the Things need to be in different target sectors, but the target sectors can share the same tag.

The Thing determines whether the special pushes or pulls, as well as the actual point of force. The Angle of the Thing determines the radius of the effect (maximum is 359), while the control linedef's length determines the general pushing/pulling strength.

If Flag [6] / Not Climbable is checked, the pushing/pulling effect is made exclusive – once an Object has been pushed/pulled by this effect, it cannot be pushed/pulled by any other pushing/pulling 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.
