Use the on_d3d_resetĪnd on_d3d_lost events for this. If you use the pd3ddev for allocatingĪn object, like a nonmanaged texture or buffer, you have to release the objectīefore switching video, and recreate it afterwards. The Direct3D device when the video output is switched between window and fullscreen no need to close the scene - this is handled by the engineīy the way, the same code also runs under lite-C - you can find an example under draw_begin.ĭepending on the 3D hardware, sometimes the engine has to release and reallocate Pd3dDev->DrawPrimitiveUP(D3DPT_TRIANGLEFAN,1,(LPVOID)v,sizeof(VERTEX_FLAT)) Pd3dDev->SetTextureStageState(0,D3DTSS_COLOROP,D3DTOP_SELECTARG2) Pd3dDev->SetTextureStageState(0,D3DTSS_COLORARG2,D3DTA_DIFFUSE) Pd3dDev->SetRenderState(D3DRS_ALPHABLENDENABLE,FALSE) set some render and stage states (you have to set some more, normally) LPDIRECT3DDEVICE9 pd3dDev = (LPDIRECT3DDEVICE9)draw_begin() open the scene and get the active D3D device V.rhw = v.rhw = v.rhw = 1.0 // no perspective V.z = v.z = v.z = 0.0 // z buffer - paint over everything

#define D3DFVF_FLAT (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) It in a wait(1)-loop, the triangle will be permanently on the screen. Upper left corner when you call PaintD3DTriangle() once. You'll see the triangle briefly flashing in the To the DirectX documentation that is available, along with the DirectX 9.0c The example paints a multicolored triangle onto the screen. *ev struct declared in avars.h, or can be obtained through the draw_begin function. The Direct3D functions are accessed throughĪ LPDIRECT3DDEVICE9 pointer that is available through the ENGINE_VARS As lite-C also natively supports DirectX functions, you don't need to write a plugin for using DirectX.Īll DirectX initialization is done by the engine, thus it's sufficient The DirectX SDK version used by the engine is mentioned in a comment in the avars.h header file. You'll need to download and install the DirectX SDK by Microsoft before you can use DirectX function in a plugin make sure that it's the same version that the engine uses. The following example shows how to use DirectX functions for creating someĮffects on the screen.
