Thanks to lazy bones for providing so many demo tutorials, it is really helpful for beginners.

Note:This section only records the experiences of bloggers who have learned the legend of war.

1. ccsprite captures small images from a large image

 
//// Ccrectmake is constructed as the UI coordinate, and the origin is in the upper left corner. Ccsprite * sp = ccsprite: Create ("menu.png", ccrectmake (0,0, 120,0 ));//
 

2. Global variable extern

 
/// Declare in. h: extern ccarray * play_bullet; // defined in. cpp: ccarray * play_bullet = NULL ;//
 

3. ccmenu Layout

 
/// 1. arrange all buttons in the menu vertically and set the spacing to 20. menu-> alignitemsverticallywithpadding (20); // 2. vertically arranged by menu items and placed each line of Ci elements menu-> alignitemsincolumns (C1, C2, C3 ,..., CN, null );//
 

4. ccmenuitemtoggle

 
// Ccmenuitemfont * on = ccmenuitemfont: Create ("On"); ccmenuitemfont * off = ccmenuitemfont: Create ("off"); optional * toggle = ccmenuitemtoggle :: createwithtarget (this, menu_selector (options: setoptions), off, on, null); // you can set the toggle-> setselectedindex (1) starting from 0 );//
 

5. Enable and disable the entire function.

 
//// The largest integer less than or equal to X double floor (Double X); // the smallest integer greater than X double Ceil (Double X );//
 

6. Random number 0 ~ 1

 
// Ccrandom_0_1 ();//
 

7. Action Decomposition

When an animation consists of multiple actions, the animation can be decomposed.

For example, it is divided into moving, amplifying, rotating, etc. It is processed separately and then integrated into a complex action.

8. process decomposition

(1) checkiscollide (); // collision detection (blood only)

(2) removeinactiveunit (); // remove inactive elements (destroy dead fighters or ***)

(3) checkisreborn (); // the rebirth of the fighter plane, or the end of the game (re-resurrection)

(4) updateui (); // refresh the interface

9. hybrid mode

10. Airplane touch movement

// Void game: cctouchmoved (cctouch * touch, ccevent * event) {If (ship! = NULL) {ccpoint Pos = touch-> getdelta (); // get the offset ccpoint currentpos = ship-> getposition () of the touch screen sliding (); // obtain the current plane coordinate currentpos = ccpadd (currentpos, POS); // The coordinate currentpos = ccpclamp (currentpos, ccpointzero, mysize) after the plane + offset ); // The screen ship-> setposition (currentpos) cannot be removed; // set the coordinates after the plane moves }}//
