I have recorded a small video showing the first test. As you probably think, I could make the ground commander building each one of the units spawned by it at first place but with the amount of these units, it would require probably a lot of code and I want make one thing faster. It makes the same in less time.
I could add the "Request new reinforcements" ability in the ground commander but it adds a problem, if you make ctrl+A selecting all the units, you will not see them and in a first place I tried it but I have changed it, probably in a better way. Now the ground commander deploy a building which it can act as a communication building where you can request the new reinforces.
As you can see the new reinforces are added in the reinforce list and they will be spawned only if you lose your units, in fact you will require get the landing positions increasing your deployment points.
You will see in the begining how I am playing at a 3840x2160 but truly, I have not changed my Benq 24" 1920x1080 screen, just I have activated a option from the Nvidia control panel named DSR. It activates a special filter which it lets you select a 4K resolution with a 1080p screen. The filter adapts the 4K image to your 1080p screen. All the process has as result a much better quality image.
