(地基工)OIS 问题

Posted on 2010-12-15 15:29 点点滴滴 阅读(279) 评论(0)  编辑 收藏 引用 所属分类: 08 游戏SDK
1.当窗口最小化后,单击只有按下无弹起事件
void MouseDeviceOgreOIS::poll()
{
        
if (mMouse)
        {
            mMouse
->capture();
            OIS::MouseState
& state = mMouse->getMouseState();
            
//设置鼠标无法改变OIS底层GetDeviceData的数据,造成bug,需要解决。
            POINT point;
            GetCursorPos(
&point);
            ScreenToClient((HWND)mWhd, 
&point);
            Vector3 pos(point.x 
* 1.0f, point.y * 1.0f0.0f);
    
            mPosition.x 
= state.X.abs *  1.0f;
            mPosition.y 
= state.Y.abs *  1.0f;
            mPosition.z 
= state.Z.abs *  1.0f;
            
if ((mPosition.x != pos.x) || (mPosition.y != pos.y))
            {
                mPosition.x 
= pos.x;    
                mPosition.y 
= pos.y;
            }
            
if (!mActualClip.contains(mPosition))//修改OISBug,当在最小化后,单击只有按下无弹起事件。
            {
                
if(mButtons[MBT_LEFT])
                    mButtons[MBT_LEFT] 
= state.buttonDown(OIS::MB_Left);
                
else
                    state.buttons 
&= ~(1 << OIS::MB_Left); //turn the bit flag off
                
                
if(mButtons[MBT_RIGHT])
                    mButtons[MBT_RIGHT] 
= state.buttonDown(OIS::MB_Right);
                
else
                   state.buttons 
&= ~(1 << OIS::MB_Right); //turn the bit flag off

                
if(mButtons[MBT_MIDDLE])
                    mButtons[MBT_MIDDLE] 
= state.buttonDown(OIS::MB_Middle);
                
else
                    state.buttons 
&= ~(1 << OIS::MB_Middle); //turn the bit flag off                
                return;
            }
            mButtons[MBT_LEFT] 
= state.buttonDown(OIS::MB_Left);
            mButtons[MBT_RIGHT] 
= state.buttonDown(OIS::MB_Right);
            mButtons[MBT_MIDDLE] 
= state.buttonDown(OIS::MB_Middle);
            
        }
}

2.使用SetCursorPos后,无移动鼠标,OIS无法取得鼠标移动信息
void Win32Mouse::capture()
{
    
//Clear old relative values
    mState.X.rel = mState.Y.rel = mState.Z.rel = 0;

    DIDEVICEOBJECTDATA diBuff[MOUSE_DX_BUFFERSIZE];
    DWORD entries 
= MOUSE_DX_BUFFERSIZE;

    HRESULT hr 
= mMouse->GetDeviceData( sizeof(DIDEVICEOBJECTDATA), diBuff, &entries, 0 );
    
if( hr != DI_OK )
    {
        hr 
= mMouse->Acquire();
        
while( hr == DIERR_INPUTLOST ) 
            hr 
= mMouse->Acquire();

        hr 
= mMouse->GetDeviceData( sizeof(DIDEVICEOBJECTDATA), diBuff, &entries, 0 );
        
        
//Perhaps the user just tabbed away, and coop settings
        
//are nonexclusive..so just ignore
        if( FAILED(hr) )
            
return;
    }

    
bool axesMoved = false;
    
//Accumulate all axis movements for one axesMove message..
    
//Buttons are fired off as they are found
    for(unsigned int i = 0; i < entries; ++i )
    {
        
switch( diBuff[i].dwOfs )
        {
            
case DIMOFS_BUTTON0:
                
if(!_doMouseClick(0, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON1:
                
if(!_doMouseClick(1, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON2:
                
if(!_doMouseClick(2, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON3:
                
if(!_doMouseClick(3, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON4:
                
if(!_doMouseClick(4, diBuff[i])) return;
                
break;    
            
case DIMOFS_BUTTON5:
                
if(!_doMouseClick(5, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON6:
                
if(!_doMouseClick(6, diBuff[i])) return;
                
break;
            
case DIMOFS_BUTTON7:
                
if(!_doMouseClick(7, diBuff[i])) return;
                
break;
            
case DIMOFS_X:
                mState.X.rel 
+= diBuff[i].dwData;
                axesMoved 
= true;
                
break;
            
case DIMOFS_Y:
                mState.Y.rel 
+= diBuff[i].dwData;
                axesMoved 
= true;
                
break;
            
case DIMOFS_Z:
                mState.Z.rel 
+= diBuff[i].dwData;
                axesMoved 
= true;
                
break;
            
defaultbreak;
        } 
//end switch
    }//end for

    
if( axesMoved )// 有偏移信息才会设置鼠标位置
    {
        
if( coopSetting & DISCL_NONEXCLUSIVE )
        {
            
//DirectInput provides us with meaningless values, so correct that
            POINT point;
            GetCursorPos(
&point);
            ScreenToClient(mHwnd, 
&point);
            mState.X.abs 
= point.x;
            mState.Y.abs 
= point.y;
        }
        
else
        {
            mState.X.abs 
+=  mState.X.rel;
            mState.Y.abs 
+=  mState.Y.rel;
        }
        mState.Z.abs 
+=  mState.Z.rel;

        
//Clip values to window
        if( mState.X.abs < 0 )
            mState.X.abs 
= 0;
        
else if( mState.X.abs > mState.width )
            mState.X.abs 
= mState.width;
        
if( mState.Y.abs < 0 )
            mState.Y.abs 
= 0;
        
else if( mState.Y.abs > mState.height )
            mState.Y.abs 
= mState.height;

        
//Do the move
        if( mListener && mBuffered )
            mListener
->mouseMoved( MouseEvent( this, mState ) );
