Hello there!
I've been busy implementing the display of cover status. Basically I used the similar approach that XCOM uses: three types of shields (full, half-full, empty) indicating three types of cover, plus a yellow shield if a character is flanked. Here's the final result:
You might notice that I removed the HP display; I need to rework it so that is looks cleaner - so that will be the next thing that I will be able to (hopefully!) showcase to you next time!
Take care!
I like your cover system ideas, very cool!
