# Dynamic case?

I'm generating some buildings (well, building envelopes) with variable floor counts (attribute "aog") and color for each of the floors. Right now I simply have the maximum number of floors inserted manually and catch the top with "aog-1". Is there a way to do this in a more flexible way?

Here's the rule file:

```version "2014.0"

attr aog = 0
attr maxLength = scope.sx
attr maxWidth = scope.sz
attr maxHeight = 3.0*aog
attr opacityslider = 0.8

#--------------------------------

Lot -->
set(material.opacity,opacityslider)
innerRect
s(maxLength+1,'1,maxWidth+1)
center(xyz)
extrude(maxHeight)
Building

Building -->
comp(f){side: BuildingBody | top: Roof }

BuildingBody -->
split(y){ maxHeight/aog: BuildingFloors }*

BuildingFloors -->
comp(f){all: ColorMe(split.index)}

ColorMe(FloorIndex) -->
case FloorIndex == aog-1: color(0,1,1)
case FloorIndex == 0: color(1,0,0)
case FloorIndex == 1: color(0,1,0)
case FloorIndex == 2: color(0,0,1)
case FloorIndex == 3: color(1,1,0)
case FloorIndex == 4: color(1,0,0)
case FloorIndex == 5: color(0,1,0)
case FloorIndex == 6: color(0,0,1)
case FloorIndex == 7: color(1,1,0)
case FloorIndex == 8: color(1,0,0)
case FloorIndex == 9: color(0,1,0)
case FloorIndex == 10: color(0,0,1)
case FloorIndex == 11: color(1,1,0)
else: color(0.5,0,0)

Roof -->
color(1,1,1)
roofGable(35,0,0,false)
```
