It will need an empty GameObject as a target to move towards. The AIThirdPersonC ontroller can be found in the Standard Assets. ĭefine everything and click on Bake (please note that all the 3D objects should be visible before baking here, part of the buildings are hidden to show what happens). Open the navmesh by the menu Window/AI/Navigation. To have some AI guys running in our city, we will need a navmesh. It allows the player to see how the city looks in the night.Īdd some lamps props (found in the assets). The lights are important elements in a city.

Several props can be found in the assets. The animation is not really good.ģ.8 City props 3.8.1 Benches, sewers, plant pots In this example, a taxi drives around one bloc of houses.

In the Animation tab, define the animation (position, rotation at given times). We can add very basic animation to our vehicles:Īdd an Animator component to the GameObject. The objects should be defined as children of vegetation blocs it makes it easier to manage those.Īdd some vehicles to the streets. The tiles should be defined as children of terrain blocs (here we took the same blocs as for the buildings) it makes it easier to manage those.Īdd the vegetation. The buildings should be defined as children of blocs of buildings it makes it easier to manage those.Īdd some terrain tiles. Take the building 3D models from the assets. The tiles should be defined as children of streets it makes it easier to manage those.Īdd some buildings. It will be flat and the texture is set to a Dark Concrete free texture.Īdd a streets system. 3.2 3D TerrainĪs we don’t import a 3D terrain, we need to create one from scratch. Under Assets, get the assets described in chapter 2.2 and import these to the project.Ĭreate a new scene and name it M圜ity. Start Unity 3D and create a new 3D project. I used only free assets for this example. These models can also be found in some assets. The 3D models used in the city can be created in any 3D or architecture software (e.g. How-To create a 3D city 3.1 Specific 3D models 2.2.2 Unity Samples: UIįor this example, I used several free city props:ģ.

These assets can also be added directly from within Unity 3D. This collection of assets, scripts, and example scenes can be used to kickstart your Unity learning or be used as the basis for your own projects. Once downloaded, install it and create your login. Unity is cross-platform game engine developed by Unity Technologies.

Standard Assets, UI Samples, City Props: some free assets for Unity 3D.

Right now, it’s made for computers, as it uses some keyboard commands.

This could be used in the BIM world, to show a new construction project, and, more generally, for games or XR. The idea is to show how easy it is to create a whole 3D environment in which the player can walk around. Create a 3D city from scratch in one day.
