Re:[求助]关于qamin中的total和valid。。。在线等，急！
难道没有人知道吗？我说的是这个：
void StudioModel::CalcBonePosition( int frame, float s, mstudiobone_t *pbone, mstudioanim_t *panim, float *pos )
{
int j, k;
mstudioanimvalue_t *panimvalue;
for (j = 0; j < 3; j++)
{
pos[j] = pbone->value[j]; // default;
if (panim->offset[j] != 0)
{
panimvalue = (mstudioanimvalue_t *)((byte *)panim + panim->offset[j]);
k = frame;
// find span of values that includes the frame we want
while (panimvalue->num.total <= k)
{
k -= panimvalue->num.total;
panimvalue += panimvalue->num.valid + 1;
}
// if we're inside the span
if (panimvalue->num.valid > k)
{
// and there's more data in the span
if (panimvalue->num.valid > k + 1)
{
pos[j] += (panimvalue[k+1].value * (1.0 - s) + s * panimvalue[k+2].value) * pbone->scale[j];
}
else
{
pos[j] += panimvalue[k+1].value * pbone->scale[j];
}
}
else
{
// are we at the end of the repeating values section and there's another section with data?
if (panimvalue->num.total <= k + 1)
{
pos[j] += (panimvalue[panimvalue->num.valid].value * (1.0 - s) + s * panimvalue[panimvalue->num.valid + 2].value) * pbone->scale[j];
}
else
{
pos[j] += panimvalue[panimvalue->num.valid].value * pbone->scale[j];
}
}
}
if (pbone->bonecontroller[j] != -1)
{
pos[j] += m_adj[pbone->bonecontroller[j]];
}
}
}
void StudioModel::CalcRotations ( vec3_t *pos, vec4_t *q, mstudioseqdesc_t *pseqdesc, mstudioanim_t *panim, float f )
{
int i;
int frame;
mstudiobone_t *pbone;
float s;
frame = (int)f;
s = (f - frame);
// add in programatic controllers
CalcBoneAdj( );
pbone = (mstudiobone_t *)((byte *)m_pstudiohdr + m_pstudiohdr->boneindex);
for (i = 0; i < m_pstudiohdr->numbones; i++, pbone++, panim++)
{
CalcBoneQuaternion( frame, s, pbone, panim, q );
CalcBonePosition( frame, s, pbone, panim, pos );
}
if (pseqdesc->motiontype & STUDIO_X)
pos[pseqdesc->motionbone][0] = 0.0;
if (pseqdesc->motiontype & STUDIO_Y)
pos[pseqdesc->motionbone][1] = 0.0;
if (pseqdesc->motiontype & STUDIO_Z)
pos[pseqdesc->motionbone][2] = 0.0;
}
