I didn’t have the habit to centre my Command Centre to the middle of the screen, but I think there are benefits in doing so. This is something I will add to my game play, and you should too.
Camera hot key and centring
It is important to use camera hot keys to move around the bases. If you don’t, you definitely should.
As you move to different bases using your camera hot key, it is more convenient to have each of those town hall to be at the same location of the screen. The best way to ensure they are in the same location is to have them in the middle of the screen. This allows you be more efficient with the mouse movement than having the multiple town halls at different locations of the screen. When I say they are at different locations, they are still close to the middle but not exactly middle.
I will use INnoVation as the example, because, in my opinion and many others’ as well, he has the most crisp clean mechanics. If you watch INnoVation’s FPV, you may have noticed that his Command Centre are positioned in the middle of the screen and the mouse cursor does not move away from the middle more than necessary. This is because it gives you the optimal mouse cursor travel distance around the screen.
By default, the town hall is not centred when the game starts. So if you set camera hot key right from the start, it is not in the middle.
Another problem is the general habit that players will set camera hot key at the start of the game for the expansions they plan to take as the game progresses. However, the hot key-ed location is not aligned to be perfectly in the middle for the yet-to-build town hall.
Another words, you need to set the camera hot key again once the town hall has been placed in the expansion in order to ensure it is in the middle.
I overlap the images of three bases into one image to show the difference between centring and without centring. The difference is quite obvious.
Why centre the town hall
By centring the town hall to the middle of the screen, the mineral patches and gas geysers at the different bases have the similar distance to the middle of the screen or the respective town halls. Consequently, you develop a muscle memory of how far these important peripherals are from your default mouse cursor location, which is the middle. This allows you to macro more efficiently, and handle various situations better. For example, you want to drag your works away from the mineral line against a drop.
This is even more important for Zerg players as they want to cycle the different bases for larva injection.
How to centre
1. Double clicking the selection hot key.
First, group the building or the unit with a group hot key (e.g., Ctrl + 1). Then, double click the selected group hot key (double click 1).
2. Click on the image at the command bar.
3. Ctrl + f
I was asking around to see if there are other ways that I’m not aware off, and Juno has the below suggestion. I’ve yet to try it out myself.
