Conditional Rules

JoanneO_Brien

Is it possible and if so how can you create a case function which would say something like:

attr steps = "#FFFFFF"  //have shown this as colour but actually want to have steps as a  //recursion extruding away from the BaseSide if possible.  BaseVolume -->      comp(f) {side : BaseSide(comp.index) | bottom : NIL | top : extrude(height - Roof_Height) Mass }    BaseSide (myIndex) --> case myIndex == 3 && scope.sx >= 1.5:                                       split(x) {~1: color(grey) | 1.5 : color(steps) | ~1 color(grey)}                else : color(grey)

This currently isn't working but would love it to! I've attached a screenshot of one of my doors, although of course every building which has a BaseSide would have different heights below the door hence I'd love to work out using the recursion rule here too since then it could decide how many steps are needed.

I've also been trying to work out if there is a better way of assigning where the door goes but at the moment all I can come up with is telling it to put the door on wall number three, where ever that might be.

Ultimately it'd be so nice to be able to select a wall manually and then say right I'd like to use this code on this wall but that code on the others but I don't believe this is possible...

hey !

I did not get your point of the recursions. what would they be for in your case ?

btw. you can make an attr for your index. that way you can use a slider to choose the wall index interactively.

I've taken some time to code your thing very simply :

check the code very precisely and try to find out what it does.

- check out the case blocks and what is tested after each other.
- check how door placement variation is done
- check how I managed the stepping

let me know if you have more questions !
