最�q�考虑开发一�Ƒօ��Y�Ӟ��名字都想好了�Q�叫犀牛兵��，打算支持四边形地囑֒�六边形地图�?/p>

前者比较好��_��后者在�Ҏ��屏幕坐标计算格子坐标的时候，�E�微有点�ȝ��?/p>

先说下我们的坐标�p�L��x轴向叻I��y轴向上，原点在左下角�?/p>

格子地图坐标如下

�Ҏ��格子坐标计算出对应世界坐标系的函数如�?/p>

QPointF GridCell6Manager::getWorldPosByCellCoordinate(int x,int y)

{

if (x % 2 == 0)

return QPointF(1.5f*res*(x+1),

(0.5*R3+R3*y)*res);

return QPointF(1.5f*res*(x + 1),

(R3 + y * R3)*res);

}

QPoint GridCell6Manager::getCellCoordinateByWorldPos(int x,int y)

{

QPoint point(-1,-1);

float xpos = x-res*0.5f;

float ypos = y/(R3*res) - 0.5f;

int yset[2] = {std::floorf(ypos),std::ceilf(ypos)};

xpos /= (1.5*World::getInstance().getWorldResolution());

int xset[2] = { std::floorf(xpos),std::ceilf(xpos)};

auto p00 = getWorldPosByCellCoordinate(xset[0],yset[0]);

auto p01 = getWorldPosByCellCoordinate(xset[0],yset[1]);

auto p10 = getWorldPosByCellCoordinate(xset[1],yset[0]);

auto p11 = getWorldPosByCellCoordinate(xset[1],yset[1]);

float d00 = distance2<float>(x,y,p00.x(),p00.y());

float d01 = distance2<float>(x,y,p01.x(),p01.y());

float d10 = distance2<float>(x,y,p10.x(),p10.y());

float d11 = distance2<float>(x,y,p11.x(),p11.y());

int i,j;

if(d00 < d01 && d00 < d10 && d00 < d11)

{

i = xset[0];

j = yset[0];

}

else if(d00 > d01 && d01 < d10 && d01 < d11)

{

i = xset[0];

j = yset[1];

}

else if(d10 < d00 && d10 < d01 && d10 < d11)

{

i = xset[1];

j = yset[0];

}

else

{

i = xset[1];

j = yset[1];

}

return QPoint(i,j);

}

其中res为格子边长，R3为sqrt(3)帔R��

在这个基��上就可以计算从世界坐标到格子坐标的�{换了

提供StackLayout,BoxLayout,GridLayout,FlowLayout
提供CheckBox,Panel,StaticText,ImageBox,ProgressBar,TableWidget,Slider,EditFiled,Combox�{�常用控�?/li>

openal中的alThunk

ccsdu2009 — Mon, 29 Jun 2015 05:24:00 GMT

�q�个其实是一个线�E�安全的int mapper

void alThunkInit(void);
void alThunkExit(void);
ALuint alThunkAddEntry(ALvoid * ptr);
void alThunkRemoveEntry(ALuint index);
ALvoid *alThunkLookupEntry(ALuint index);

typedef struct {
    ALvoid *ptr;
    ALboolean InUse;
} ThunkEntry;

static ThunkEntry *g_ThunkArray;

void alThunkInit(void)
{
    InitializeCriticalSection(&g_ThunkLock);
    g_ThunkArraySize = 1;
    g_ThunkArray = calloc(1, g_ThunkArraySize * sizeof(ThunkEntry));
}

void alThunkExit(void)
{
    free(g_ThunkArray);
    g_ThunkArray = NULL;
    g_ThunkArraySize = 0;
    DeleteCriticalSection(&g_ThunkLock);
}

ALuint alThunkAddEntry(ALvoid *ptr)
{
    ALuint index;

    EnterCriticalSection(&g_ThunkLock);

    for(index = 0;index < g_ThunkArraySize;index++)
    {
        if(g_ThunkArray[index].InUse == AL_FALSE)
            break;
    }

    if(index == g_ThunkArraySize)
    {
        ThunkEntry *NewList;

        NewList = realloc(g_ThunkArray, g_ThunkArraySize*2 * sizeof(ThunkEntry));
        if(!NewList)
        {
            LeaveCriticalSection(&g_ThunkLock);
            return 0;
        }
        memset(&NewList[g_ThunkArraySize], 0, g_ThunkArraySize*sizeof(ThunkEntry));
        g_ThunkArraySize *= 2;
        g_ThunkArray = NewList;
    }

    g_ThunkArray[index].ptr = ptr;
    g_ThunkArray[index].InUse = AL_TRUE;

    LeaveCriticalSection(&g_ThunkLock);

    return index+1;
}

void alThunkRemoveEntry(ALuint index)

    EnterCriticalSection(&g_ThunkLock);

    if(index > 0 && index <= g_ThunkArraySize)
        g_ThunkArray[index-1].InUse = AL_FALSE;

    LeaveCriticalSection(&g_ThunkLock);
}

ALvoid *alThunkLookupEntry(ALuint index)

    ALvoid *ptr = NULL;

    EnterCriticalSection(&g_ThunkLock);

    if(index > 0 && index <= g_ThunkArraySize)
        ptr = g_ThunkArray[index-1].ptr;

    LeaveCriticalSection(&g_ThunkLock);

    return ptr;
}

用途比较广

发现一个问题imageView.startAnimation启动控�g动画以后
�׃��一些原因需要设�|�控件�ؓGONE状态，也就是imageView.setVisibility(View.GONE);
之后发现控�g处于GONE状态，但是控�g�q�是可见�?br />上网查了下发现要清空动画�Q�也��是imageView.clearAnimation

其实我觉得如果调用setVisibility(View.GONE)之后无论当前有无动画都应该消�?br />讄��为GONE状态后控�g状态出现异�?br />
按照当前情况要隐藏控仉��要先调用cleanAnimation,之后call setVisibility
所以有�I�想想android API也�ƈ非十全十��?
各位觉得呢？

c语言调用Python脚本-2

ccsdu2009 — Tue, 15 Jan 2013 13:39:00 GMT

python代码二段:

call.py

def test():
print 'hello world'

def add(a,b):
return a + b

api.py

import io

def load_test():
    fp = open('call.py','r')
    buffer = ''
    if fp:
        buffer = fp.read()
    fp.close()
    return buffer

cpp代码:

#include <stdio.h>
#include <stdlib.h>
#include <Python.h>

int main(int argc, char *argv[])
{
    Py_Initialize();
    if(!Py_IsInitialized())
    {
        return -1;
    }

    PyRun_SimpleString("import sys");
    PyRun_SimpleString("sys.path.append('./')");
    PyObject* pName;
    PyObject* pModule;
    PyObject* pDict;
    PyObject* pFunc;

    pName = PyString_FromString("api");
    pModule = PyImport_Import(pName);
    if(!pModule)
    {
        printf("can't find call.py");
        getchar();
        return -1;
    }

    pDict = PyModule_GetDict(pModule);
    if(!pDict)
    {
        return -1;
    }

    {
        pFunc = PyDict_GetItemString(pDict,"load_test");
        if(!pFunc || !PyCallable_Check(pFunc))
        {
            printf("can't find function [test]");
            getchar();
            return -1;
        }

        PyObject *pFn = PyObject_CallObject(pFunc,0);
        char* buffer = PyString_AsString(pFn);
        printf("%s\n",buffer);

        PyObject* o = Py_CompileString(buffer,"none",Py_file_input);
        PyObject* m = PyImport_ExecCodeModule("a.a",o);
        PyObject* d = PyModule_GetDict(m);
        pFunc = PyDict_GetItemString(d,"add");
        if(!pFunc || !PyCallable_Check(pFunc))
        {
            printf("can't find function [add]");
            getchar();
            return -1;
        }

        PyObject* args = PyTuple_New(2);
        PyTuple_SetItem(args,0,Py_BuildValue("l",3));
        PyTuple_SetItem(args,1,Py_BuildValue("l",4));
        PyObject *pAdded = PyObject_CallObject(pFunc,args);
        int ret = PyInt_AsLong(pAdded);
        printf("add value:%d\n",ret);
    }

    Py_Finalize();
    system("PAUSE");
    return 0;
}

�q�段代码和上一��有点区�?br />主要区别是从从内存蝲入python模块然后调用函数
主要部分是这�?

        PyObject* o = Py_CompileString(buffer,"none",Py_file_input);
        PyObject* m = PyImport_ExecCodeModule("a.a",o);
        PyObject* d = PyModule_GetDict(m);

buffer是python源码字符�?br />
在python2.7中执行正�?br />
