How to Create A Tic Tac Toe App In C# | Visual Studio 2019 | Part 1

[@zero-9435]

First of all I have to admit that this tutorial is really good, but there is one problem. If you win with the last turn, it just says „Thats a draw“ .I guess you have to add an else{CheckDraw()}

[@ShaunHalverson]

Thank you and thank you for the tip as well, it’s hard to handle all cases but I will pin a comment for future viewers!

[@cljalamana1190]

This channel is by far the best way to learn

[@cljalamana1190]

But i do recommend when you write code you say the code and zoom in so that we dont need to set quality to 720p and load longer and put our eyes on the screen to see the code

[@ShaunHalverson]

I'm glad you think so! This comment means alot, thank you very much :)

[@ShaunHalverson]

@@cljalamana1190 I will keep that in mind! Was the level of Zoom that i had on this video okay ? Or should I zoom in even more than i already did ?

[@cljalamana1190]

@@ShaunHalverson i reccomend zooming in much more

[@Havii]

@@ShaunHalverson For VStudio this is actually pretty okay. For web videos, zoom in would be very useful since it's pretty small and it hurts my eyes if I have to focus hard 😅 But like he said, definitely the best channel to learn. I love your videos a lot.

Thank you for these awesome videos!

Glad you like them!

You are the best chanell for learn.

Thank you :)

Your case 6 and 7 on CheckForWinner function are a bit wrong. For example the index for case 6 should be" combination = gameboard[1], [4] and [7]" for the vertical winning line. The first index gameBoard[2] is the only incorrect number in your combination code for case 6 :). Error came from writing 1,2,3 at the top line boxes instead of 0,1,2 @16:00. Other than that an excellent tutorial video!

[@ShaunHalverson]

Thank you for the feedback!

[@itz_jiryn8162]

Wery helpful, thack you!

[@ShaunHalverson]

Glad to hear it!

[@sam_the_yardman]

this video is good, no cap

[@mstrnabeel2605]

Nice dude, very helpfull. But i have a query. If we double click on a button that button will change from X to O or O to X.. that needs to be validate. How will we do that.

[@mstrnabeel2605]

Also if we have more than one combinations to win then it also shows us game is drawn.

[@ShaunHalverson]

Hmmm. Thank you for reporting these bugs! I will need to glance at the code and get back to you with how to fix it.

[@mstrnabeel2605]

Thanks dude ! 👏

[@ShaunHalverson]

So I just took a look, maybe try moving checkdraw() after the winning if/else statements? That way the winner will be checked first and if there isn't one, it will then check for a draw. Let me know how that works.

[@mstrnabeel2605]

Ok I'll check..

[@zero-9435]

Hi there is the problem that if you win with the last turn, it just keeps saying „Thats a draw“ and it doesnt work with else checkfordraw. Do you maybe know how to fix this issue?Thy

[@purd691]

When I write “button1.Text = gameBoard[0]; it says “CS0103 The name ‘button1’ dose not exist in the current context” may you please help

[@ShaunHalverson]

That kind of looks like your button1 might be in a spot that isn’t accessible to everything. Can I see your code somehow?

[@agentbomz1222]

Can you pls make a vid so u can play with an ai? I have mid term on this and I have no idea how to do it

[@ShaunHalverson]

I would love to, but I unfortunately don't have any experience with AI yet. I would like to get into that for future videos tho. Just super complicated stuff!

[@agentbomz1222]

It's ok :)

[@EeveeShadowBacon]

My i's for the (i=0,i

[@ShaunHalverson]

You need to say int i=0 in the first part

[@ShaunHalverson]

Also make sure you have semicolons in between each one for(int i=0; i < 8; i++)

[@EeveeShadowBacon]

@@ShaunHalverson got it, thanks

[@mackl0533]

For my if(combination.Equals(“000”)) it keeps saying system.NullreferenceException : object reference not set to an instance of an object Pls help

[@ShaunHalverson]

I think it’s complaining that your combination variable is not being set somewhere and by the time the if fires, there’s no .equals property to access because the object is null

[@mackl0533]

@@ShaunHalverson so how would I go about fixing it

[@ShaunHalverson]

@@mackl0533 check your combination variable and compare it with the video to see if you missed anything. If you can't find anything, you can add me on discord @ Shaun#5626 or paste your code here and I can take a look

[@fizamubeen7701]

Hey sir can you please give this game source code because I have some error

[@ShaunHalverson]

I actually got a new computer and don’t have the source code anymore lol, but what is your error? I can try to help

[@balkanxd5900]

When I type combination = gameBoard[0] + gameBoard[4] = gameBoard[8]; and then say is error

[@ShaunHalverson]

Hi! So the issue with that example is that you can’t have 2 equal signs in one statement. Did you mean to type that?
