Module Builder

Functions to create and destroy buildings, roads, trees and more.

For convenience you can provide the id of a draft as a string instead of the draft itself whenever a draft is needed. There are different types of drafts. Ensure that you use the correct functions to build them. For example you cannot build $park00 by using Builder.buildRoad. Since it's a build you would have to use Builder.buildBuilding instead.

For each type of object that can be built there's typically a function to check in advance whether the actual building process will be successful. It's good style to use these checks, even though the builder functions check validity on their own.

Usage:

    if Builder.isBuildingBuildable('$tree00', 2, 4) then
  Builder.buildBuilding('$tree00', 2, 4)
end
