Here we design a natural landscape with a small waterfall using Unity and a few free assets.
Assets:
– Standard Assets
– Terrain Tools Sample Asset Pack
– Unity Particle Pack
– Grass Flowers Pack Free
– Rock and Boulders 2
– Free SpeedTrees Package
– AllSky Free
Sample pictures
In this game By targeting an image, the player sees the 3D model of the maze and plays with it by rotating the image.

The stick is moved up and down with a mouse click, and the balls are created by pressing R, B and C on the keyboard.
This is a simple 3D game tutorial made with Unity that uses first person character and in it you will see how to use terrain, post-processing, physics, static and dynamic sun, moving stick and creating balls with C# codes.
