Hi there.
Could some kind person please point me to a tutorial or examples for drawing a circle around a player character in a 3d environment (kind of rts style) that:
- Isn’t a projector.
- Isn’t a line renderer.
- Will follow (render on top) or terrain or geometry.
- works with 2020.
Many thanks.
While on the subject, is the projector going to be updated? If it’s so expensive to use why is it still there? It’s still available to add to a basic 3d project when it’s completely unusable. It either needs fixing or removing and replacing. Surely?
you’ve ruled out everything I can think of but drawing directly onto a texture (very expensive), or modifying a shader to draw a dynamically positioned circle (perhaps somewhat less expensive).
There are no tutorials for what you are looking for, but there are several around the topic.
Do a google search on “texture2D drawing” ; “draw a circle using a shader” or similar search terms.
You can do this with Scriptable Rendering pipelines using similar techniques as in this video:
The video doesn’t cover your exact use-case but it should be enough to get you started. This also requires you to be using HDRP or URP in your project.
