Flappy Bird 2

This is a remake of the previously uploaded game Flappy Bird which features a more intuitive design which allows users to change the speed, and makes the input easier. The code was completely rewritten, and has been tested. It now appears to be bug-free. If it does not work when you enter it into your calculator, make sure you have entered everything correctly! This code has been proven to work by either the download or the source code. + Show Click here to see a video of me using the download to prove it is functional. Click here to see a video of me using the source code to prove it is funtional. To change the speed, change the first line of the program. A lower number stored into D will make the program faster, higher numbers will make it slower. D must be at least 1.

Nice work Trenly! This has been needing fixing for quite a while, so great job! :)

EDIT: Might I suggest that you use ">" instead of "►"? I feel like newbies won't know that it's not obtainable without the use of something like CHARS.

Changed it in the code, but not the program download. Thank you for your suggestion.

A few things

Myles_Zadok 11 Mar 2017 22:31

I typed this into my TI-84+ CE and noticed a few improvements that could be made.

1) The first digit of the score is displayed at an X-coordinate of 16. On older calculators, the second and third digits of the score are displayed at coordinates of 1 and 2, respectively. The display should be at 14 to prevent a looped score.

2) The way the game ends when the bird dies is kind of abrupt, so Pause should be put after the last End.

Also, I made a full screen version for the TI-84+ CSE and CE:

15→D
ClrHome
4→Y
⁻1→S
Repeat Y>10
randInt(3,7)→H
S+1→S
For(V,26,1,⁻1)
If Y>10:Stop
If V=2 and (Y≠H and Y≠H-1):Stop
If Y≤10:Output(Y,2,">"
For(E,1,H-2)
Output(E,V,"I"
End
For(E,H+1,10)
Output(E,V,"I")
End
For(E,1,D)
End
For(E,1,10)
Output(E,V," " //one space
End
Output(1,24,S
getKey→K
If not(K)
Then
If Y≤10:Output(Y,2," " //one space
Y+1→Y
End
If K and Y>1
Then
If Y≤10:Output(Y,2," " //one space
Y-1→Y
End
End
End
Pause

I'll upload the CSE/CE version to the archives shortly.

I will change the download in a few minutes to reflect the movement of the score. Download updated

The abrupt ending was for optimization purposes. Also a pause at the end wouldn't do anything. It also allows users who want to modify or expand upon this program to learn a little bit possibly.

It kept on telling me there was a domain error on the 13th line

Check your code. This program has been proven to work. If you don't believe me, watch the youtube videos

Hello,

I have figured out a way to do high score:

Before (If Y>8: Stop), put:

If Y>8: Output (3,4,"HIGH SCORE:")
If Y>8: Output (4,8,Z)

Then do the same kind of command before (If V=2 and (Y(not)=H and Y(not)=H-1): Stop), using the beginning for the if statement.

Finally, go down to the three End functions at the bottom, and enter (If S>Z:S(store/arrow)Z) after the first End function

Now, when you die, it will show your score and your highest score to date below it. I think it adds to the overall effect.

Trenly 16 Mar 2017 23:26

I was well aware of that, but using a variable like Z can be unsuitable since it can sometimes be overwritten. As I said in earlier replies, The abrupt ending was for optimization purposes. It also allows users (like yourself) who want to modify or expand upon this program to learn a little bit possibly.

But good job for figuring out that you would need to change the statements after the conditionals to do anything.

So what variable should we use instead?

Myles_Zadok 06 May 2017 23:02

You should use a variable that you don't use in any other program.

Hawkee (guest) 06 May 2017 23:20

Ok, thanks.

lord_of_the_keyboard 10 May 2018 20:42

why dont you make the high score a one number list, like

1→ dim(ʟFBS)
→ ʟFBS(1)

hss20 (guest) 20 Mar 2017 21:43

Which button do you press to go up?

Bob (guest) 06 Apr 2017 14:52

Any key will work to go up

hss20 (guest) 20 Mar 2017 21:47

Sorry I couldn't edit the last post. When I press the up button or enter, the bird stays on the same row but it doesn't move up, no matter how fast I press.

Myles_Zadok 20 Mar 2017 22:33

Did you make sure the code you have is exactly the same as it appears at the top of the page? Carefully compare the code on your calculator to the code above and you'll probably find the cause of your problem.

Trenly 20 Mar 2017 23:02

Any key works as the input, and it works flawlessly for me. Try making sure the code is exactly the same as it is at the top of the page

irenew (guest) 21 Mar 2017 00:29

Hi, I have the same problem as the above poster. Would you mind directing me to the part of the code that dictates where the "bird" should go up when pressing a key? Also, when you press, is the bird supposed to move up a row?

Myles_Zadok 21 Mar 2017 02:25

The "K"s have to do with the pressing a key.

Trenly 21 Mar 2017 03:53

The part where it says

getKey-> K

is the part where it is detecting a key press. Everything else where the variable K is used is moving the bird up or down. In both of the videos below you can see I use more than just the enter key to move the bird up.

What is the box underneath 4 sto Y

Battlesquid 03 Apr 2017 13:29

Uh…this?

⁻1→S

That's a negative sign before the 1. Not really sure what you need, could you elaborate :)

-1→S

Bob (guest) 06 Apr 2017 14:55

Hi! Could someone help me with the high score system?

Myles_Zadok 06 Apr 2017 15:18

You'll first have to change the conditionals from Stop to a Goto command, and then have a Lbl command and your code for a high score system at the end of the program (it is pretty simple, so I'll let you figure it out on your own). I hope this helps.

Battlesquid 06 Apr 2017 15:25

You could also look at this highscores article. :)

I received a Domain Error on line " Output (E,V,"I"

Trenly 09 Apr 2017 23:33

You must have typed something wrong. The code works flawlessly, as shown by the videos in the post.

Mr.Sir (guest) 10 Apr 2017 00:21

I double checked. I don't know what's wrong.

Mr.Sir (guest) 10 Apr 2017 00:28

I type it in Output(E,V,"I"

Boomcoding 26 Oct 2019 00:36

What are the Symbols in the 3 boxes??
I can't seem to figure the 3rd one…and it's messing up the whole code

Boomcoding 26 Oct 2019 00:52

Nevermind I recoded the errors…..works so much better now…..tweaked the codes a little bit though
