Linedef type 13

An example map with the heat wave effect.

Linedef type 13, Heat Wave Effect, is a type of linedef special which generates subtle horizontal lines scanning upwards in every tagged sector. This effect is useful for creating an area in a map that gives the impression of being very hot. Note that the effect is only visible when the camera is inside the tagged sector, not the player. Note that this effect cannot be applied to all sectors in a map at once by giving it a tag of 65535; this won't work. However, there is an easy workaround: Create an invisible, intangible FOF and give its control linedef a tag of 65535 to make it cover the entire level. Then, apply the heat wave effect to the control sector of the FOF.
