X-Com style interface

I'm working on my first unity project, and I'd like to create a control interface similar to how X-Com works. So, the player can move units - the have a cursor indicating which space the unit will move to. Potentially, there's also a line indicating the path the unit will take.

So far, the best way I've thought to do this is with a game object for the cursor (like a semi-transparent wireframe cube). I don't like it, but I could construct the path indicator with a set of game objects that are elongated cylinders for each line segment. Is there a better way to approach this? Is there an example out there of a system like this?

 

Are you meaning A, B, or C?

I'd use a cube for A, a Line Renderer for B and probably a Sprite for C

 

Thanks, that's what I was looking for. How would you handle the health display for each unit? It's just a billboarded texture, right?

Also, using the line renderer - if I wanted a multi-segment line with sharp angles, would I need a different line renderer for each segment?

 

A texture will work fine, using a transparent cutout shader to reduce/increase the visible health. Though have a look at nGUI or Daikon Forge - they may be more useful or easier to set up.

LineRenderer supports multi-segment, if you plan to make it curved you'll probably have to split the line and calculate x/z positions yourself.
