Laser FOFs in Egg Rock Zone Act 1.

Linedef type 258, Laser, is a type of floor over floor block which acts like a laser beam. This FOF is intangible, blinks very rapidly, generates laser ambience (sound sfx_laser), and harms the player on contact with generic damage. It is commonly used with the REDWALL texture and the REDFLR flat, or other solid-color textures and flats. Lasers can be found throughout Egg Rock Zone, where they exhibit various elaborate effects and movement patterns created with the use of other linedef specials.

Setup

The flats, floor height, and ceiling height of the laser FOF are determined by the flats, floor height, and ceiling height of the control sector, and the sidedefs of the laser FOF's walls are determined by the sidedef of the controlling linedef. If the Slope Skew flag is checked, the laser will not damage bosses.

Aesthetic tips

It is recommended that lasers be assigned solid colors on their sides and flats, to simulate a realistic laser beam. Solid red and solid blue laser beams look the best, although yellow, orange, purple, green, and white lasers are also possible.
