Problematic key combinations

[Unitkiv]

I have a soccer player. The player has high kick and low kick. My problem is when I use certain key combinations, the player doesn’t perform the kick process for instance, down-left or down-right and E works for low kick since it doesn’t work for vice-versa or up-left or up-right and K works for high kick since it doesn’t work for vice-versa. Why is this happening, How could it be fixed?

First thing to check is the hardware:

Keyboard rollover, jammed keys, bad key combinations:

Controls: having Trouble doing multiple actions at the same time

It may be a case of keyboard rollover: Key rollover - Wikipedia To prove or disprove it, make a simple script that displays the different keys that you need held down when they are held down, see if that simple script can show all the keys at once that you intend to hold down simultaneously. If it can, then you may have a bug in your as-yet-unposted code. If the keys can’t all be held at once, that’s your keyboard’s limitation.

If that works, then you just have a bug you have to fix. Change your code so that pressing ANOTHER key simulates (mocks) pushing the multiple keys you want and find out how the logic is going wrong.

Thank you for clarifying. I just found the key combinations with the help of Online Key Rollover Test - Mechanical Keyboard
