# Buildings & Resources

Back to table of contents
Buildings and resources are what this game is all about. The focus of the game is to find a balance between both production and consumption of food resources and gold income and costs that lead to a high population count, a positve balance due to big tax payment by your citizens and therefore prosperity.
The way offered by the game to influence all that, is by constructing different kinds of buildings. These buildings are now described below.

## House

Property | Value
--- | ---
Name: | House
Price: | 15
Regular costs: | 0

A house is the fundamental buildings in the game. Houses are the entities that allow you to strongly influence the growth of the number of your population (inhabitants). And your population count is the decisive factor for your tax income. One inhabitant is equal to one gold unit paid for taxes.
Citizens are responsible for decrease of your food reserves, too. One citizen consumes 1.5 units of food every time interval. The calculate the amount of consumed food, just multiply the number of citizens by 1.5. If the resulting food consumption is a floating point number it gets rounded.
For example five citizens consume 5*1.5 = 7.5 food units, but the result gets rounded to 8. If you place a house in the scene, your population will instantly increase by one. After a certain time interval the number of inhabitants of a house will either grow or fall by one.
If the number increases or decreases is influenced by a minor random factor and by the amount of food available. It is easy to understand that the population count will strongly tend to fall, if your food supply is at zero capacity and rise if you still have food reserves for your citizens.

## Farm

Property | Value
--- | ---
Name: | Farm
Price: | 20
Regular costs: | 6

Farms are the buildings in the game that produce food. One farm produces 20 units of food that get added to the player's overall food resources every certain time interval. But building a farm also causes some regular costs of 6 gold units that get subtracted from the player's gold resources ervery time intervall.

## City Hall

Property | Value
--- | ---
Name: | City Hall
Price: | 25
Regular costs: | 9

City halls are the central buildings for the player to collect taxes from the population. Only if the player places a city hall into the scene, taxes are being collected. One city hall has the capability to collect at most 20 units of gold from taxes. Hence if the player has built one city hall and suddenly the population count has risen higher than 20 (20 citizens = 20 gold units of taxes), the player needs to build another city hall in order to collect all the taxes.
Nevertheless city halls suffer from pretty high regular costs. Every city hall built causes regular costs of 9 gold units affecting the player's gold resources.

## How to place a building

It is quite easy to place a building in the scene. Just use the camera control keys to navigatr to the location chosen for construction of the selected building. If the underlying terrain at the designated location is absolutely plain, the building can be placed by pressing the space bar.
It is possible that a building cannot be palced due to collision with another building intersecting with new building or because the terrain is not totally plain at the planned location. In that case, the game will give an acoustic feedback that states the current issue with construction.
