3. FileUtils file operation tool class it shields mac ios android and other platforms

FileUtils file writing and reading: if it is a Mac platform, the available Directory is: [/Users/beyond /Documents/] For iOS platform, the available Directory is: [.../app /Documents/ ]

Iv. Plist File Reading
The FileUtils tool class is still used.
The returned type is [ValueMap] or an array [ValueVector]
V. XML file reading



Library Used for parsing XML in cocos2d

# Include <tinyxml2/tinyxml2.h>

6. Reading JSON files

Cocos2d built-in Json Parsing Library

# Include <json/rapidjson. h>

# Include <json/document. h>

Mark parseFlags as 0 by default.

Output result:

8, Plist files and large images exported through Flash CC, Create Frame AnimationFirst, download flash_professional_13_ls1_dmg and run the patch about 1 GB.
Open Flash, open 【 Library], Click the new button in the lower left corner to create a new Symbol, and select [video Clip Movie Clip] As the type. draw a square in 1st frames and press F6 to create a key frame in 20th frames; delete the original square from the second frame and draw a circle. Right-click any frame between the two key frames and create a [deformation compensation animation shape tween, focus: export the large texture + Plist file used for cocos2d, click the library, right-click the created video clip movie clip, and select Generate Sprite Sheet ], select cocos2D v3 for data format and Export. A plist file and a large texture image are generated, as shown below:
Plist File
Relationship among SpriteBatchNode, texture cache, and SpriteBatchNode

9. Create a frame animation large image texture for the Json file and large image exported through Flash CC, as shown in:
The exported Json data is as follows:

{"frames": {"hero0000":{"frame": {"x":0,"y":0,"w":44,"h":52},"rotated": false,"trimmed": false,"spriteSourceSize": {"x":0,"y":0,"w":44,"h":52},"sourceSize": {"w":44,"h":52}},"hero0004":{"frame": {"x":42,"y":52,"w":42,"h":52},"rotated": false,"trimmed": true,"spriteSourceSize": {"x":2,"y":0,"w":44,"h":52},"sourceSize": {"w":44,"h":52}}},"meta": {"app": "Adobe Flash Professional","version": "13.1.0.226","image": "Hero.png","format": "RGBA8888","size": {"w":128,"h":128},"scale": "1"}}

The following code uses the built-in rapidJson parsing in cocos2d and encapsulates it into an Animate object (runAction can be directly used)

How does delphi7 save input timer data?

I'm not sure what you want to ask ????

Hitting timer Data Processing

Uniformly accelerated linear motion
Object velocity at different time points
V1: V2: V3. ......: Vn = ......: n
Object displacement in Ts at the same time interval
S1: S2: S3:...: Sn = ...... :( 2n-1)
