Question

I have a vector called actorVector which stores an array of objects of type actorManager.

The actorManager class has a private attribute, which is also an object of type GLFrame. It has an accessor, getFrame(), which returns a pointer to the GLFrame object.

I have passed a pointer of actorVector to a function, so its a pointer to a vector of objects of type actorManager.

I need to pass the GLFrame object as a parameter to this function:

modelViewMatrix.MultMatrix(**GLFrame isntance**);

I’ve currently been trying to do it as such, but im not getting any results.

modelViewMatrix.MultMatrix(*(*actorVector)[i].getFrame());

Any ideas?

Answer 1

Assuming MultMatrix takes an ActorManager by value or by reference (as opposed to by pointer), then you want this:

modelViewMatrix.MultMatrix(*((*actorVector)[i].getFrame()));

Note that the precedence rules mean that the above is equivalent to:

modelViewMatrix.MultMatrix(*(*actorVector)[i].getFrame());

However, that’s what you already have, so there must be something you’re not telling us…
