CityEngine - Rule File Unexpected Token

ÓrlaHammond — Mon, 15 Feb 2021 00:01:19 GMT

Hi there,

I'm having a problem with a rule file I inherited. The original rule file was written for CityEngine 2016. I would like to update it so it runs in CityEngine 2020.

I am getting a recurring error: Unexpected token. This error is repeated throughout the code wherever there is a decimal value.

A snippet of the code throwing the error is below and I have attached a screenshot of the errors.

Any and all help is appreciated!

Lot1 --> #Where there is no commercial in the suburb and the % of residential buildings is >0 case NoCommercialInSuburb == "No Commercial" && PercentBuildingsResid > 0 : set(Ground_Floor_Resid, "GroundFloorResid") set(First_Floor_Resid, "FirstFloorResid") set(PercentUpperFloorResid, 1) Lot1.5 # Default method of allocating floorspace between residential and non-residential is to do so by floor. # This code below checks the ResidAllocationMethod parameter and switches the allocation method to building by building instead. case ResidAllocationMethod == "By building" && (FixedRandomNumber/100) <= PercentBuildingsResid : set(Ground_Floor_Resid, "GroundFloorResid") set(First_Floor_Resid, "FirstFloorResid") set(PercentUpperFloorResid, 1) Lot1.5 case ResidAllocationMethod == "By building" && (FixedRandomNumber/100) > PercentBuildingsResid : set(Ground_Floor_Resid, "GroundFloorNonResid") set(First_Floor_Resid, "FirstFloorNonResid") set(PercentUpperFloorResid, 0) Lot1.5 else : Lot1.5

@ÓrlaHammond

I think CityEngine uses the decimals in text strings to find file paths. You might do a quick find/replace of "Lot1.5" to "LotB" and see if that solve your problems.

For example:

import Complete_Streets <file path>

call the rule: Complete_Streets.Sidewalks or Complete_Streets.Streets

Hi Brian,
