Here is a screen sot of how my game looks now. Each star is this dot with a little ring around it. The inside little ring is roughly the area, where I should click, when I want to select it. The bigger grey circles are just a representations of star productiveness. On the right side, a little bit above the center is star, which has a cross through its center. That star happens to have a fleet currently there.Fleets can only move from star to star.
Here is a pic of how my game currently handles selection. That same star is currently selected. You can see that this generated a little info about this star in the toolbar below. It's resource value, which is the numerical representation of the grey circle around it. And fleet size. Fleet size is it's current carrison and this fleet cannot move. This fleet can move if a Carrier Fleet comes by and I transfer the carrison over to the Carrier fleet. I am planning to make all star related operation to be left side of the toolbar nad all Carrier Fleet related operations to be on the right side of the toolbar.
But the problem is, that I can only fit one carrier fleet at a time on the toolbar. But due to the nature of the game, it is inevitable that two or more carrier fleets are going to end up on one star.
My problem with two fleets: When I click on the star, computer selects everything in the area of roughly one white star. This means that, at one point I have to make something that allowes me to select from a selection of Carrier Fleets currently orbiting the star. But I have no idea how to do that.
I am not trying to prevent multiple fleets at once.
Internally I have fleet management covered. Each fleet has it's own coordinate variable.
