Creating a minimap
In this recipe, we will create a minimap. An ordinary minimap features the basic points of navigation, typically in the shape of a circle or a square. In some instances, a minimap features a scaled-down real-time version of a map. In others, it may be a simplified version of the terrain. Whatever the case may be, minimaps prove to be a useful feature when traversing large landscapes, and they are also a way of indicating to the player the locations of various items. In this recipe, you will start learning how to use render textures and raw images. You will also learn how to set the position of the camera according to the player's position.
How to do it...
First of all, we need to create the scene in which we can test the minimap.
To quickly generate a 3D environment, we can use the Terrain object, which we can create by right-clicking on the Hierarchy panel and then going to 3D Object | Terrain.
Now, in the Inspector, we can choose different tools to model it. Feel free to...
