Rendering the minimap
The minimap is one of the most important resources for the player to master an RTS game. It shows a top view of the level and the discovered areas and it can track the enemy movements and highlight where the player is now. In this chapter, we are going to set up the minimap UI and the new camera to display the current level in the minimap. In later chapters, with more data available and game mechanics implemented, we will add more features to the minimap, so we need a solid foundation now.
So, we just learned how to use the Render Texture to display the camera render in a texture, and then add that texture to the UI. Now we are going to do the same process again but with a new Render Texture, Material, and Camera.
As we did previously, we can start creating the Render Texture and the Material that will be used by the minimap in the UI:
- Right-click on the Textures folder and select Create | Render Texture. You can name it
MiniMapRenderTexture.
