Trying to add Polymorphism to my 'Turn base Snake Game"

[grizzled egret]

Good Morning! I am currently having issues on a project I am doing for school. It is a spin on the 90's game, snake. The only difference is that it is turn based. I am currently trying to add BonusItems, or superPowers to my game. Right now I want to add a bonus item that doubles the score, but for some reason it is not working. ANY help will be grately appreciated

The files for powerup are:
PowerUp
DoubleScore

perhaps

It has the same number of syllables as “TERMINAL SNAKE GAME” 😛

[odd plinth]

no way

(what does?)

[plush girder]

in applyPower(int score) the score is a local variable.
You probably meant that to be int&

nice catch

Turn based Snake Game

[odd plinth]

ah

Does it?

It is a terminal game. Turn base snake game. I did change the this...i'll run it and see if the changed make it work

[plush girder]

primarily you should understand what the change does

[grizzled egret]

umm. Okay, so as of now I am just lost on the state of polymorphism and the intersection of my code, how would this change enact the power up to work ?

'based' sounds like one syllable usually

Change was done, but now an error appears on LevelManager.getscore())

        {
            if(activePowerUp != nullptr && activePowerUp->isActive()){
 //error               activePowerUp->applyPower(LevelManager.getScore());
            }else{
                LevelManager.increaseScore(100);
            }
            
        }```

[plush girder]

what you want is probably this:

    if (gameBoard.checkCollisionWithFood())
    {
        int score = 100;
        
        if (activePowerUp != nullptr && activePowerUp->isActive())
        {
           activePowerUp->applyPower(score);
        }

        LevelManager.increaseScore(score);
    }

applyPower(int& score) expects a variable that can be altered (called l-value in c++ speak)
