Until AngelScript supports static arrays, you can register this by registering your own array type, which you then register as the member of the Box class:

RegisterObjectType("vec3arr8", sizeof(Vector3[8]), asOBJ_VALUE | asOBJ_POD | asOBJ_CLASS);
RegisterObjectBehaviour("vec3arr8", asBEHAVE_INDEX, "Vector3 &f(uint)", asFUNCTION(vec3arr8_index), asCALL_CDECL_OBJLAST);


Vector3 *vec3arr8_index(unsigned int idx, Vector3 *arr)
if( idx >= 8 )
asGetActiveContext()->SetException("out of bounds");

return &arr[idx];

r = engine->RegisterObjectProperty( "Box", "Vector3@[] mVectors(8)", offsetof( ScriptBox, mBox.mVectors ) );

can I register the array like this ?

I wish I could say yes, but the changes are too complex for me to be able to implement this for the next version.

If you can live without the array being an array in the script you can also register it as 8 separate properties, e.g:

RegisterObjectProperty("box", "float m1", offsetof(Box, mVectors));
RegisterObjectProperty("box", "float m2", offsetof(Box, mVectors) + 4);
RegisterObjectProperty("box", "float m3", offsetof(Box, mVectors) + 8);
