oh! i didn't notice that this is in the latest beta already.

i did use a dll so far. now i tried to use setmatrix() in lite-c but i didn't get it working. no crash happened but the shadows were gone when i substituted the dll function.

do the LPD3DXEFFECT functions work correctly for you?

I haven't had time to try them yet, I just saw that the beta page says the effect interface was added in the version that was released jan 31.

Cool work ventilator & Excessus, please keep up the good work

Wish I could help I'm going to learn shader coding very soon.

D3DXVECTOR3 vZ = vTarget - vSource;

but since lite-c doesn't support oo features you have to convert such stuff to:

D3DXVECTOR3 vZ;
D3DXVec3Subtract(&vZ, &vTarget, &vSource);

Hi, I'm currently trying to convert the source codes of the example you mentioned but I don't get this step. The functions D3DXVec3Subtract, D3DXVec3Add and D3DXVec3Scale aren't defined in the d3d9.h. I tried to do this myself but didn't succeed, as I don't know how to make the prototypes for these functions, which aren't winapi function prototypes as for example D3DXVec3Normalize. How did you manage to use these functions in LiteC???

i wasn't aware of that when i wrote this post. i used the d3dx matrix functions before in lite-c so i thought the vector functions are there too. i simply used the gamestudio vec_ functions then. it doesn't make much difference. you just have to do conversions at some places where a d3dx vector is needed as a function parameter.

Ok that's what I tried before, but it didn't work so I guess I probably didn't make those conversions right . So I would use native liteC floats arrays for the d3dXvectors and convert them to a d3dXvector when it's needed as a parameter in a function. How do I convert it? Setting each parameter like this? tempd3dvector.x = tempfloat[0];
tempd3dvector.y = tempfloat[1]; //or swapped with z
tempd3dvector.z = tempfloat[2]; //or swapped with y

And swapping y and z when converting GS vector syntax to DirectX vector syntax?

yes, like that:
Code:

---

		// transform corner point
		D3DXVECTOR4 transformed;
		D3DXVECTOR3 v;
		v.x = corners[i].x; // directx coordinate system!
		v.y = corners[i].z;
		v.z = corners[i].y;
		D3DXVec3Transform(&transformed, &v, &lightviewprojection);

Ok, Thanks .
