Skies, Floors and Ceilings¶

Skys are larger than the screen and are made up of two 256 x 200 grabs in posts similar to the walls. The first grab represents the bottom part of the sky and the second part the top of the sky. The skys are denoted by the labels SKYSTRT and SKYSTOP.

Floors and ceilings use the following structure:

lpic_t :: struct {
    width: i16le,
    height: i16le,
    orgx: i16le,
    orgy: i16le
    data: []byte,
}

They can be found between the labels UPDNSTRT and UPDNSTOP. They must be 128 x 128 in size.
