# BaseCosts NewGRF

### From #openttdcoop wiki

## Info

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>**
where

**<base cost no>**is an entry from the first column of the base cost list

and

**<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.

### Presets

the presets GRF has at least 4 sets saved. (Homepage)

Table: http://dev.openttdcoop.org/projects/basecosts-presets/repository/changes/BaseCostsTable.ods

Please suggest new presets to the tracker.

## Examples

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
