What you are talking about is the most substitutive touch system in 2K series. Similar to the cell phone signal, the more four signal slots are filled, and with reasonable shooting time, the shooting hit rate can be greatly guaranteed. As for color, yellow stands for ordinary, followed by orange and red. At the bottom: blue and purple. This is the so-called explosive feel and so on. Different players have different abilities, which are explained in detail in the player evaluation. The higher the numerical value, the stronger the hand feel retention ability.
Grasping this system, 2K 1 1 shooting will become a big killer.
I hope it will help you and I hope it will be adopted.
