I am developing a gdextension. I'm one of those people who cannot live without C++. Also, I'm binding to other, external C++ libraries.
Let's say in my C++ code I have a Transform3D called t and a Vector3 called v. Now I want to apply the transform to the vector. According to the documentation of Transform3D it has a Vector3 operator * ( Vector3 right ) which multiplies the Vector3 by the Transform3D. So I expect to be able to say t * v. However, when I do that the compiler complains that such an operator* does not exist. In fact, when I look at the source code for Transform3D, the operator does not exist.
It seems that instead calling t.xform (v) does what I intended.
I have some questions. Help is much appreciated.
What language(s) does the class reference apply to?
How does the class reference relate to the C++ code?
How do I, in the general case, find out how to implement, in C++, the features described in the class reference?
