Hiya guys,
This problem I have... I just can't figure why it is giving me a compile error when it looks perfectly fine, as far my my understanding goes.
But basically I got a Vehicle class, Spacecraft class, and a Fightercraft class.
Vehicle is parent of Spacecraft, Spacecraft is parent of Fightercraft.
I have a variable that is a pointer to Vehicle class, but it is actually a Fightercraft class object.
When I go to use a method that I know it has access to that exists in the parent class it says that member is not a member of Vehicle.
I give you guys a sample of the code
//This code exist in my main application entry point
Vehicle *player = new Fightercraft( "player", &D3DDevice );
And my inheritance for the Vehicle, Spacecraft and Fightercraft is as follows
//----- VEHICLE DEFINITION SECTION -----//
#ifndef VEHICLE_H
#define VEHICLE_H

Sorry about the long code sample guys.
The error I am getting is
error C2039: 'getMaterial' : is not a member of 'Vehicle'
I thought my player variable can reference the getMaterial function because it is inherited by all child classes as well.
All the text I've read and all the on-line stuff I research tells me what I am doing should be ok.. yet I don't understand this compile error.
I am missing a fundamental concept with this line I think
Vehicle *player = new Fightercraft( "player", &D3DDevice );
Obviously player variable is still being view as a Vehicle object.
Sorry about the long post guys :(
How can I reference getMaterial function?
