I would like to suggest a blank HUD sprite(s), along with a number/set of numbers that is unused. I would also like a "Linedef Executor - Add Floor to Custom HUD", which would use the floor height as a value to add to the custom HUD value, with negative numbers subtracting, and using the X offset to determine which number if more than one are available. And also a "Linedef Executor - Set Custom HUD to Floor". Self explainatory if you read the description of the other one. Maximums, minimums, and positions of the custom HUD would be set with SOCs, and the HUD sprite would be an image in the WAD, preferably CUSTHUD1, CUSTHUD2, and so forth for however many there are.
