Generating Buildings at Runtime

To see this in action head open the example scene BuildR2\Genesis\Genesis Runtime Example.unity in your Unity project.

The following code takes a Genesis Plot defined in the editor (selectedPlot) and generates a building inside it at a specified interval (generationTime) using a defined set of building constraints (constraint).

using UnityEngine;
using BuildR2;
using BuildR2.Genesis;

public class SimpleRuntimeExample : MonoBehaviour
{
public BuildingRuntime building;
public BuildingContraints constraint;
public GenesisPlot selectedPlot;
public float startTime = 1.0f;
public float generationTime = 10.0f;
private GenesisSettings _settings;

private void Start()
{
_settings = GenesisSettings.Get();
InvokeRepeating("Generate", startTime, generationTime);
}

private void Generate()
{
if(building!=null) building.Clear();

GRandom.GenerateNewSeed();
_settings.seed = GRandom.seedInt;
selectedPlot.density = GRandom.Range(10, 20);
building = BuildingGenerator.CreateRuntime(selectedPlot, constraint, _settings.defaultGeneratedBuildingName);
}
}

The Generate() function is called at the specified interval and is the method used to generate a new building from scratch.

1	building.Clear()

Remove all the currently used renderers that have been allocated

1 2	GRandom.GenerateNewSeed(); _settings.seed = GRandom.seedInt;

Create a new random seed and assign it to the global setting seed.

1	selectedPlot.density = GRandom.Range(10, 20);

Modifying the plot density will change the height of a generated building. Here it will be randomly chosen between 10 and 20.

1	building = BuildingGenerator.CreateRuntime(selectedPlot, constraint, settings.defaultGeneratedBuildingName);

Finally the BuildingGenerator creation method is called. The plot, constraints are passed and it will output the generated building.
