|
|
Prosty kod dla połączenia edytora z silnikiem. Na svn wrzuciłem low level kod tego rozwiązania.
Ogólnie na wyższej warstwie abstrakcji mamy:
| Kod: | void processMessage( WPackage& package )
{
switch (package.msgType)
{
case 2:
{
//ustawiamy okno
}break;
case MT_RENDERVIEWRESIZED:
{
//w edytorze zmieniono rozmiar okna widoku
}break;
case MT_VISIBLECHANGED:
{
//analogicznie
}break;
case MT_MOUSEBUTTONUP:
{
//…
}break;
case MT_MOUSEBUTTONDOWN:
{
//..
}break;
case MT_MOUSEMOVE:
{
//..
}break;
case MT_KEYDOWN:
{
//..
}break;
case MT_KEYUP:
{
//..
}break;
case MT_WNDACTIVESTATE:
{
//..
}break;
}
SAFE_DELETE_ARRAY(package.pData)
}
|
Np: taka funkcja w silniku przyjmuje wiadomości od edytora.
A tak to może wyglądać od strony c#:
| Kod: | public enum MsgType
{
MT_CLIENTID=0,
MT_CONSOLEMSG=5,
MT_RENDERVIEWRESIZED=4,
MT_VISIBLECHANGED=6,
MT_MOUSEMOVE=7,
MT_KEYDOWN=8,
MT_KEYUP=9,
MT_WNDACTIVESTATE=10,
MT_MOUSEINSIDE=11,
MT_MOUSEBUTTONDOWN = 12,
MT_MOUSEBUTTONUP=13
}
public class WindowEvents
{
public NetworkHandling handler;
private WPackage package = new WixPackage();
private mouseInfo mousePos = new mouseInfo();
private InegerData intData = new InegerData();
public WindowEvents()
{
package.length = 1;
}
public void sizeChanged()
{
package.msgType = (UInt32)MsgType.MT_RENDERVIEWRESIZED;
package.length = 1;
handler.sendPackage(package);
}
public void visibleChanged(Boolean visible)
{
package.msgType = (UInt32)MsgType.MT_VISIBLECHANGED;
package.pData =(UInt32)(visible==true?1:0);
package.length = 1;
handler.sendPackage(package);
}
public void renderWndActive(bool active)
{
package.msgType = (UInt32)MsgType.MT_WNDACTIVESTATE;
package.sender = (UInt32)(active == true ? 1 : 0);
package.length = 1;
handler.sendPackage(package);
}
public void mouseMove(Position pos)
{
package.msgType = (UInt32)MsgType.MT_MOUSEMOVE;
package.length = sizeof(Int32) * 2;
package.sender = 1;
mousePos.mousePos = pos;
handler.sendPackage(package, mousePos);
}
public void keyDown(Keys key)
{
package.msgType = (UInt32)MsgType.MT_KEYDOWN;
package.length = 4;
package.sender = 1;
package.pData = 0;
intData.integer=(Int32)key;
handler.sendPackage(package,intData);
}
public void keyUp(Keys key)
{
package.msgType = (UInt32)MsgType.MT_KEYUP;
package.length = 4;
package.sender = 1;
package.pData = 0;
intData.integer = (Int32)key;
handler.sendPackage(package, intData);
}
/*
*
* */
public void mouseDown(MouseEventArgs e)
{
package.msgType = (UInt32)MsgType.MT_MOUSEBUTTONDOWN;
package.length = 1;
if(e.Button==MouseButtons.Left)
{
package.sender = 0;
}
else if (e.Button==MouseButtons.Right)
{
package.sender = 1;
}
handler.sendPackage(package);
}
/*
*
* */
public void mouseUp(MouseEventArgs e)
{
package.msgType = (UInt32)MsgType.MT_MOUSEBUTTONUP;
package.length = 1;
if (e.Button == MouseButtons.Left)
{
package.sender = 1;
}
else if (e.Button == MouseButtons.Right)
{
package.sender =2;
}
handler.sendPackage(package);
}
} |
gdzie samo połączenie:
| Kod: | public class NetworkHandling
{

catch (System.Exception ex)

}
public WPackageHolder getPackageBase(UInt32 readhead)

if (bytesRead <= 0) done = true;
else
{
bytesRead += n;
UInt32 readHead = 0;
while ((bytesRead - readHead) > sizeof(WPackage))
{

readHead += pckSizeTotal;
}
else
{

n = (int)(bytesRead - readHead);
break;
}
}
if (bytesRead < maxSize) done = true;
}
}
}
return true;
}
public Boolean sendPackage(WPackage package, SendObject sendObject=null)
{
unsafe
{
Int32 size = (Int32)(sizeof(WPackage) + package.length);
if (size > maxSize) return false;
using (MemoryStream m = new MemoryStream())
{
using (BinaryWriter writer = new BinaryWriter(m))
{
writer.Write(package.msgType);
writer.Write(package.sender);

if(sendObject!=null)sendObject.convertToBytes(m_pBuffer);
}
}
try
