DX9动画控制
SmoothChangeAnimation函数申明:
void SmoothChangeAnimation(LPD3DXANIMATIONCONTROLLER pAnimController,LPD3DXANIMATIONSET pAnimSet,FLOAT fCurrTime);
SmoothChangeAnimation函数实现:
void SmoothChangeAnimation( LPD3DXANIMATIONCONTROLLER pAnimController, LPD3DXANIMATIONSET pAnimSet, FLOAT fCurrTime ) { static DWORD dwOldTrack = 0; static DWORD dwNewTrack = 1; dwNewTrack = dwOldTrack == 0 ? 1 : 0; pAnimController->SetTrackAnimationSet( dwNewTrack, pAnimSet ); pAnimController->UnkeyAllTrackEvents( dwOldTrack ); pAnimController->UnkeyAllTrackEvents( dwNewTrack ); pAnimController->KeyTrackEnable( dwOldTrack, FALSE, fCurrTime + 0.125f ); pAnimController->KeyTrackSpeed( dwOldTrack, 0.0f, fCurrTime, 0.125f, D3DXTRANSITION_LINEAR ); pAnimController->KeyTrackWeight( dwOldTrack, 0.0f, fCurrTime, 0.125f, D3DXTRANSITION_LINEAR ); pAnimController->SetTrackEnable( dwNewTrack, TRUE ); pAnimController->KeyTrackSpeed( dwNewTrack, 1.0f, fCurrTime, 0.125f, D3DXTRANSITION_LINEAR ); pAnimController->KeyTrackWeight( dwNewTrack, 1.0f, fCurrTime, 0.125f, D3DXTRANSITION_LINEAR ); dwOldTrack = dwNewTrack; }
