Setting the costs by using the id from BaseCosts Table and the value n of the following formula:
Using math: NewBaseCost = OldBaseCost * 2^(n-8), where n is the value of property 08.
You can only rise base costs by factors which correspond a power of 2. The general way to set parameters are in pairs of two:
<base cost no> <exponent of multiplicator>
<base cost no> is an entry from the first column of the base cost list
<exponent of multiplicator> is the n in the multiplicator to the original base costs: 2^(n-8) Thus a value of 8 will leave the costs unchanged, a value of 9 will double it, 10 will quadruple it and 7 will half it.
the presets GRF has at least 4 sets saved. (Homepage)
Please suggest new presets to the tracker.
config for raise Terraform (x16), but keep foundations on default:
using Pikka's pb_build but modify foundations:
using my Presets GRF followd by base costs mod
New version 5: one parameter per cost:
other similar grfs are:
- Pikka's "Modified Building Costs" (doesn't respect the new OpenTTD feature which splits terraform and foundations)
- Terkhen's "Raise landscaping costs"
- my old grfs: BaseCosts Mod 2 and Airmod
