If you used git add to trace the items you want to submit, but suddenly you found you add the wrong items… in the first time, you can use git status to check the add item list, and use git reset to cancel the item.
If you want to make objects that follow the player’s movement in Unity, such as pets or coffins (?), then we can use List<Vector3> data type variables to store the player’s moving route (that is the position that exists at each point in time). And keep the position of the object that you want to follow the player updated.
The different objects in Unity may have a parent-child hierarchical relationship, and if we want to confirm how many child objects there are under an objects, we can use the follow program to do it:

In the past, I always used Resources.LoadAll<Sprite>() to create an Array<Sprite> object, but today, when trying to optimize the program, I tried to change to Resources.Load<Sprite>() to read a specific Sprite.
Recently I migrated my developed Unity game from Windows to Mac OS, but when I connect to my test device and compile the APK file to run, I got the following error message:

When using Numpy format data for conditional judgment, sometimes we get the following error message:
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()When we talking about data processing related to arrays and multiple dimensions, you will think of Numpy. This is because Numpy as an optimized library composed of C/C++ and Fortran, and its computational efficiency is very fast.
