我想为我的C ++游戏引擎创建一个使用Direct3D(不是Direct2D)的GUI系统。我创建了一个D3DXSprite,分配了一个D3DXTexture,使用背景以外的另一种颜色来绘制它……仍然没有显示。我在这里做什么错了?
#include <d3dx9.h>
_Obst_PanelDx9::_Obst_PanelDx9( _Obst_Gui* owner, _Obst_Vector2& size ) : _Obst_Panel(owner)
{
m_position = _Obst_Vector2( 0, 0 );
m_size = size;
m_color = _Obst_Vector4( 1, 1, 1, 1 );
D3DXCreateSprite( ((_Obst_Gui*) owner)->getDisplayContext()->getD3Ddevice(), &m_sprite );
D3DXCreateTexture( ((_Obst_Gui*) owner)->getDisplayContext()->getD3Ddevice(), m_size.x, m_size.y, 0, D3DUSAGE_DYNAMIC, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, &m_texture );
}
_Obst_PanelDx9::~_Obst_PanelDx9()
{
if ( m_sprite ) m_sprite->Release();
if ( m_texture ) m_texture->Release();
}
void _Obst_PanelDx9::render()
{
m_sprite->Begin( D3DXSPRITE_ALPHABLEND );
//m_sprite->Draw( m_texture, 0, 0, &D3DXVECTOR3(m_position.x, m_position.y, 0), D3DCOLOR_ARGB((int) (m_color.w * 255), (int) (m_color.x * 255), (int) (m_color.y * 255), (int) (m_color.z * 255)));
// In order: ID3DXTexture* t, RECT* srcRect, D3DXVECTOR3* center, D3DXVECTOR3* position, D3DCOLOR color
m_sprite->Draw( m_texture, 0, 0, &D3DXVECTOR3(0, 0, 0), 0xFFFFFFFF);
m_sprite->End();
}
On the following image,如果我没记错的话,窗口的左上角应该有一个白色正方形。
我尝试调整alpha值,颜色,调整D3DUSAGE,D3DPOOL和D3DFORMAT枚举,设置精灵的变换矩阵,设置中心点和srcRect参数...
编辑:忘记了,我的目标是不显示图像,子画面就像面板小部件(彩色矩形)。只是ID3DXTexture包含大小值。
