hge source explor 0x4 input module

Input Module

　　hge中的输入并没有用到Direct Input，在window消息构造输入信息。

　　对于鼠标和键盘，输入信息用一个结构来处理，hge中的信息事件的结构

/*
** HGE Input Event structure
*/
struct hgeInputEvent
{
    int        type;             // event type
    int        key;              // key code
    int        flags;            // event flags
    int        chr;              // character code
    int        wheel;            // wheel shift
    float      x;                // mouse cursor x-coordinate
    float      y;                // mouse cursor y-coordinate
};

　　从结构中可以看到一个事件中同时包含了鼠标和键盘的属性，其中flags表示的标志。这个flags的标志为所有的功能键的集合，flags整数，每一位代表一个功能键。在hge.h中列出了功能键的集合。

　　

/*
** HGE Input Event flags
*/
#define HGEINP_SHIFT　　　　　　1
#define HGEINP_CTRL　　　　　　 2
#define HGEINP_ALT　　　　　　  4
#define HGEINP_CAPSLOCK　　　　 8
#define HGEINP_SCROLLLOCK     16
#define HGEINP_NUMLOCK        32
#define HGEINP_REPEAT         64

　　在hge中对于鼠标和键盘的信息还保存在引擎中

hge_impl.h

int VKey; int Char; int Zpos; float Xpos; float Ypos; bool bMouseOver; bool bCaptured; char keyz[256]; CInputEventList* queue;

　　再有在hge.h中的关于按键的键码
