Sector_SetCeilingScale

188:Sector_SetCeilingScale (tag, u-int, u-frac, v-int, v-frac)
170:Sector_SetCeilingScale2 (tag, u-fixed, v-fixed)

• tag: Tag of affected sector
• u-int: Integral part of the horizontal scalar
• u-frac: Fractional part of the horizontal scalar
• v-int: Integral part of the vertical scalar
• v-frac: Fractional part of the vertical scalar

• u-fixed: horizontal scaling factor as fixed point value
• v-fixed: vertical scaling factor as fixed point value

Scales the ceiling texture in the specified sector horizontally (x) and/or vertically (y). The formula for calculating a scaling value with the specials is the same as Sector_SetCeilingPanning and Sector_SetFloorPanning.

Sector_SetCeilingScale2 allows to specify the scaling factor directly as fixed point value. As a result, it cannot be used on a line; only in a script.

UDMF

If you are using UDMF and do not intend to modify the ceiling's scale later on, you can directly set this in fixed point under the sector's custom tab.
