[ODE] Help using ODE with DirectX

[Duncan Frostick]

Hi, That first version dosn't work, the crash still happens and I don't 
know why, this is what I'm trying now, but it won't compile, see the 
line below:

int numVertices = in->GetNumVertices();
dVector3* verticesODE = (dVector3*)malloc(numVertices*sizeof(dVector3));
Vertex* verticesDX = 0;
in->LockVertexBuffer(0,(void**)&verticesDX);
for (int i = 0; i<numVertices; i++) {
	dVector3 temp;
	temp[0] = verticesDX[i]._x;
	temp[1] = verticesDX[i]._y;
	temp[2] = verticesDX[i]._z;
	temp[3] = 0.0f;
	*verticesODE = temp; //error: '=' : left operand must be l-value
	//can be verticesODE[i] = temp; with omitting of next line
	*(verticesODE++);
}
in->UnlockVertexBuffer();

Any idea why this is illegal? Because I'm lost... this is so frustrating 
for such a simple algorithm... I just don't know what the hell is going 
wrong with it. I know it's got nothing to do with ODE, and I know it's 
got something to do with me messing up the pointers, but without a 
debugger, I'm at a loss to see what's going on. Please someone put me 
out of my misery!

Cheers for your help, Duncan
