Linedef type 12

Several rock spawners that spawn different types of rocks.

Linedef type 12, Rock Spawner Parameters, is a type of linedef special which is used to set the parameters for a rock spawner.

Setup

The tag should be the same as the Angle of the rock spawner Thing. The direction of the control linedef determines the direction in which the rocks are spawned. The length of the linedef determines the speed of the rocks (16 fracunits of the linedef length equal 1 fracunit per tic of speed), and the front texture X offset determines the time in tics it takes to spawn a rock. The front texture Y offset determines the sprite used for the rocks, as shown in the table below.

Y offset	Sprite prefix	Rock sprite	Description
0	ROIA		Brown rock
1	ROIB		Brownish-gray rock
2	ROIC		Gray rock
3	ROID		Bluish-gray rock
4	ROIE		Brownish-gray rock with orange spots
5	ROIF		Red rock
6–15	ROIG–ROIP	(None)	Blank slots

Checking Flag [6] / Not Climbable will add a random number between 0 and 8 to the speed of the rocks, in fracunits per tic.
