Broken Calculator Game Problem PLEASE HELP!

[GobinG]

What is it you are trying to achieve?

What is the problem you are having?
<First to get to the problem just press start, and go to LEVEL 2 as its the only one that works. So basically the equals button doesn't work. As well as the addition operation. Try multiplying 2 and 3, and the equal button doesn't work. BTW I am a beginner, and this is my culminating project worth 20 %>


Describe what you have tried to solve this problem

*looks through uncommented code to find which line handles mouse clicks on the equality button*

Turing:

elsif x > 750 and x < 820 and y > 140 and y < 70 then

Think carefully about what the conditions are. Will these conditions ever all be true at the same time?

Turing:

elsif x > 660 and x < 730 and y > 70 and y < 140 then     op := "+" elsif x > 660 and x < 730 and y > 250 and y < 320 then     op := "*"     exit

Why does the multiplication button work and not the addition button? What is different in the code?

I realize I'm being overly critical of your comments (or lack thereof), but if you want someone to help you, adding a few comments help a lot. (It may even help you realize what's wrong on your own)

[GobinG]

Sorry about that. Thanks for commenting though. As for the equality button I found the mistake thanks to you, it was a careless mistake by me. The code was,

elsif x > 750 and x < 820 and y > 70 and y < 140

As for the addition button I still don't see a difference in the code.

BTW, thanks for hinting the answer instead of telling me, it helps.

Turing:

elsif x > 660 and x < 730 and y > 70 and y < 140 then     op := "+" % 1 line of code elsif x > 660 and x < 730 and y > 250 and y < 320 then     op := "*"     exit % 2 lines of code

You just werent paying attention when you wrote the if statement. You said the upper boundary is 70 and the lower boundary is 140. Therefore, for the button to work, the mouse has to be above 140 and below 70 at teh same time.

[mirhagk]

@racknarg, um no it doesn't. It must be greater than 70 and less than 140.

Though I guess that particular one had already been pointed out and fixed.

This is your culminating? I wish my culminating was this easy.

[Raknarg]

Varies between teachers. I don't think there is any specific curriculum for compsci, because so far I've seen 5 grade ten compsci classes doing totally different things.

[mirhagk]

there is one. You must learn what variables and if statements are, that's about it lol. Oh other then the stupid stuff about the environment and jobs and crap.

[Raknarg]

oh yeah, we only did that part for two weeks, then we went on to turing for the rest of the semester. I actually learned a lot that whole year, I had a good teacher luckily

[GobinG]

Thanks for replying guys. As for the culminating, it was our choice of either making a game of our choice or some storybook. So I choose the game.

Thanks Dreadnought again, I fixed the problem. Just some more careless mistakes by me.

Now some how I have to figure out how to make the calculator do problems like 2 * 3 + 2. And how to make the AC Button function like it's supposed to be in a real calculator.
