I have downloaded the source but I don't know what to do now, if I make a new glut project and select the source folder and it says its invalid, what do I do now?
yes I followed that tutorial, but it doesn't work. when I try to compile anything I get errors like [glut function name] wasn't declared in this scope and unused variable [glut function name]. In that tutorial it talks about putting a .a file somewhere, but there wasnt a .a file in the download?
i have spent some time trying to install glut in code blocks and so far I haven't succeeded. i have downloaded the glut-3.7.6-bin from here . I have looked at tutorials on where to put the files in the download (like here) but it doesn't work. :icon_question::icon_question::icon_question:
#include <stdio.h>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
class M
{
public:
int value1;
int value2;
};
class P
{
public:
int sum(M n){
int t = 2;
int s = n.value2 + t;
return s;
}
};
int main(){
M m;
P p;
m.value1 = 1;
m.value2 = 2;
int res = p.sum(m);
cout << "sum is: " << res;
cin.get();
return 0;
}
I compiled it with minGW in code blocks and it worked fine (after I added return; and took main() out of a class) so maybe its something to do with the compiler/ ide your using
as I said i am new to classes, with a few minutes of tinkering I moved the implamentation of pet.edit() to after the function declarations and the class to above the functions but below the global variables. that is a better way though, I will change it. thanks for teaching me something :)

you know i just came to that conclusion when I reset the code to an earlier date when it worked, and remade the class, it didnt work so i put it where i put the pet struct! and it worked.
(I'm learning) and the reason I didn't figure out the bug in the fist place is because I didn't know whether I could use functions inside a class
OK, ill give you the whole poject, this is my first big project in c++ (I know I'm stupid and shouldn't start big, but it worked until I added classes) be warned its over 1600 lines of code (and I don't want to waste too much of your time)
I understand what your saying but I have been programming for about a year and I think I am ready, as I can go at my own pace, and I am going to get a book to learn from. I'm asking because I don't know where to go from here. I want to learn one of the api's but which one would be better to learn. would openGL do everything that direct3d can?
Yes sorry, I wrote that in a hurry, but that isn’t the problem with the other code. I know that sort of defeats the object of the example but with the code I wrote I had included all the things you mentioned and still didn’t work. the function had a prototype and the class had a semicolon. but the compiler said that the function was not declared in the scope. however i will look through the code again and see if it was somthing else
how can I use a function inside an object? (the code is too long to put here but here's a replica)
class example {
public:
example();
~example();
void doSomthing() {
afunction();
}
}
void afunction() {
//do more things
}
in this example i wouldnt NEED to use a function but I do need to in my code. when I try to compile the program I get errors like: error: 'functionName' was not declared in this scope. and error: unused variable 'functionName'
how much more do i need to know then? i can: print to a console (obviously) take user input use files use loops (for, while, do) use decisions (if, if else, switch ect) and i grasp the concept of how memory is allocated and i am begining to use classes (and i understand constructors/destructors)
and this isnt the first language i have programmed in.
I have recently learnt the basics of c++ but I want to advance to making proper GUI's (and games) but I don't know what to use. I think the two most popular libraries are OpenGL and Direct3d but I'm not sure which one to use. could you guide me in the right direction:)
