Drawing a map to a texture
In my Unity3D game I want to display a map overlay on the screen, but I also want the user to be able to pan the map around. To start I created a Scroll View on my UI Canvas. However, since my maps are loaded from disk / randomly generated I can't simply create a bunch of Image objects in the editor.
From what I see I have two basic options, please let me know if I'm missing something:
Within a Script generate a bunch of Image objects and place them inside the Scroll View content pane object.
Create a RenderTexture and draw the map in my script then place that inside as the Scroll View content.
I decided to try the RenderTexture route since it seems to be more flexible. In some cases I need to be able to draw partial pieces of images and stuff for doors. Plus creating individual (possibly hundreds) of UI Image objects seemed like a bad idea.
I'm using Graphics.DrawTexture after using Graphics.SetActive to change the active render texture.
Is there an easier way to do this?
