C++: unlock somthing

[lumpybanana247]

how can i make it so for example, at the end of a level in a text-based(C++) RPG, it actives something like a function so it unlocks the next level. such as

at the end of Level One,

UnlockLevel2
 

then at the other part of my script,

if(UnlockLevel2)
{
bool Level2();
}
 

I just dont know what to put there.
thank you

You can have an array of bools showing which levels are unlocked:

bool unlockedlevels[NUM_LEVELS] = {false}; //initialize all to false
...
...
if (currentlevel is beaten){
    unlockedlevels[current_level_num - 1] = true;}
...
...
if (unlockedlevels[level_number - 1] == true){
    do stuff for that level}
 

Is that what you're looking for?

Well, i dont really understand that code, so ill explain more.
Lets just PRETEND that im making a game where you just say what the program tells you to and you win. (i do know there is a simpler format and i know how to do it) but this is what i want it to do.

in one .cpp file,

#include "Library.h"
bool Main
{
  cout<<"what would you like to do?";
  cout<<"1.Level One";
  if (LevelOneComplete)
     {
     cout<<"2.Level Two";
     }     
}     
 

Then, in another .cpp File (same project)

#include "Library.h"
bool Level One
{
cout<<"Congrats, you beat level one.
(LevelOneComplete)
}

}
 

Ok,
so you want when something happens to complete that level and unlock the next, then run that next level, right?
You can have a bool data type that tells you wether a level is completed or not or a bool that tells wether a level is unlocked or not:

bool level_one_complete = false;   //beggining of game; level one is not complete
bool level_two_unlocked = false;   //level two not unlocked yet
 
//game passes
//...
//player completes level one
 
level_one_complete = true;     // level one is now completed
level_two_unlocked = true; //level two is unlocked since level one is complete
//somewhere later in game:
if (level_two_unlocked == true){
     //run function for level 2}
 

Does that help, or do you need some more?

Check out the State Design Pattern.

State is a pattern where each state knows the following state only. This pattern is a way to make a C++ object appear to change its type. Each of the derived classes represent your various states (the levels) of your game.

Yes, ilikepython's worked well.
thank you very much
