how can I program a blueprint that let me draw a rectangle on the screen and get every actor inside that rectangle selected like the selection tool in the 3ds apps.

For a PC game, there’s actually an video series on this.
Fast forward to around 1:40 if you have everything else set up, since all he did was create an HUD class, binded it to the game mode and is in a new blueprint interface
Although it’ll help if you are aware that this is tied to your camera’s blueprints and you’ll have to a few more things to get your units to move. About 45 minutes worth of work.

Yeah, just bear in mind that he didn’t get around to unit combat, yet.
