Study Notes for beginners, please correct me if you have any mistakes. The number is also please point out, thank you.Since the 2D audio system ignores the spatial location, we can add audio source and audio listener to the same game object.1 Create a new sceneThe audio listener component is already on the 2Main camera game object and continues to add an audio source component to it3 Specify audio clip as "11.5BMG" and check loop to set loop playback4
Given a 2D matrix matrix, find the sum of the elements inside the rectangle defined by it upper left corner (
row1,
Col1) and lower right corner (
row2,
Col2).
The above rectangle (with the red border) are defined by (row1, col1) = (2, 1) and (Row2, col2) = (4, 3), which contains Su m = 8.Example:Given matrix = [ [3, 0, 1, 4, 2], [5, 6, 3, 2, 1], [1, 2, 0, 1, 5], [4, 1, 0, 1, 7], [1, 0, 3, 0, 5]] Sumregion (2, 1, 4, 3), 8

The conversion of the 2D is achieved by transform, which has 4 different ways:
Displacement: translate (x-coordinate, y-coordinate), which is the displacement from the upper-left corner to the origin, without affecting other elements
Scaling: Scale (x multiple, y multiple), which is scaled at the origin of the element center
Rotation: Rotate (degrees), which rotates at the origin of the element center.
Skew (twist): Skew (x degrees, y d

Integers in each column is sorted in ascending from top to bottom.

1. Quartz 2D is a two-dimensional drawing library that closely integrates with the iphone OS to work with all relevant frameworks, including Core Animation, OpenGL es, and Uikit.2. Quartz's drawing function depends on 3 core concepts: Context, path, and state.① Context: The user describes where the graphic is written, and the procedure is defined by Cgcontextref . In general, you can write to UIView or bitmaps. ② Path: The path is something that is of
