Hi,
I'm new out here and I wanna program a RPG game on my TI-83+. The thing is that the only thing I ever programmed was stuff to help me at school such as Pytagore, Area & Volume, etc... I never programmed game.
I use to understand program by looking at the code, but I can't find RPG code..
Anyone can explain me (in brief) the steps to follow to create a game ?
Also, anyone have a game code I could see ? Don't worry, I won't copy ;)
Thank you very much,
Shiver
P.S. How do we set the controls ? (e.g. Right key means go right) |

| Look at getkey for controls. One thing, though. If you have no idea where to start, I would start making smaller things like tic-tac-toe. |

| Well like they said you need to know the neccasary codefirst. Then, you'll have to think of how the controls are. is it just Menu's r maybe some actual movement. Then you need to build the thigs up. A good thing to lean to do first is how to disp a character on the home or graph screen and have them move when you press the right buttons. Small things like that. |

Ok, thx a lot guys 
Btw, is it better to make the maps and movements in the Home Screen or in the Graph Screen ? |

That's a matter of opinion. homescreen is easier and faster but graphscreen has the most potential for nice graphics.
however, some amazing games have used homescreen maps. notable projects are pokemon purple or half the projects Omni makes.
if you're starting out, I recommend visiting omnimaga.org . you won't find me there, but you'll get plenty of help and support no matter which style you choose. |

I'm more active over on Omnimaga, but UTI is nice too. If you would like to see what can be done on the homescreen, then look no farther than this game: http://www.omnimaga.org/index.php?action=d...a=view;down=455
It uses one asm program, to copy a program into RAM from Archive, so it can be ran. Other than that the entire >100000 byte game is written in Basic. Illusiat 13 is my favorite calc game ever, and I'm pretty sure it's opened people's eyes to what can be done on the homescreen. :)
Since this is you're first game, I'd reccomend writing it on the homescreen. However if you would like to see what can be done on the graphscreen, the I would like to point out my current project, Elmgon: http://www.omnimaga.org/index.php?topic=1326.0
Good luck!

I began to learn how to make maps with Ti-Basic Dev (great site btw) and it seems way easier in the homescreen.
For my project, I don't want real nice graphics.. Just some letters to make the walls, etc.. So I guess the homescreen is a good choice, am I right ?
Still trying to figure out how to move... But I'll keep at it and get along with it!
Another thing, how do we say that, for example, when I press the "," key, it opens an in-game menu ?
Thx a lot for your helpful answer :D

| Well, the getkey for that is 62, I believe. So basically, you would have a variable that would hold the status of the menu. If the menu was closed, the arrows move the character. If the menu is open, arrows allow selecting in the menu. Just use the key to toggle that variable and displaying the menu vs displaying the game. |

It's great to see you progress. :)
If you would like comma to open up a menu, you'd need to do something like this:
:getKey->K
:If K=62
:Then
Menu code here
:End
Movement is something like this (I'm only moving left and right, so you can figure out up and down. ):
:8->A
:ClrHome
:Repeat K=105 //Loop until you press Enter
:Output(1,A," //One Space
:Repeat Ans //Loop until you press any key
:getKey->K
:End
:Output(1,A,"*
:A+(Ans=26 and A<16)-(Ans=24 and A>1->A //Note how the closing parenthesis is not needed before the "->".
:End

Ill help you but if this is your first game youve made you should probably start with something a little easier
to make a constant movement
:1->X:1->Y
:4->A:7->B
:DelVar KWhile not(K
:Output(A,B,"_
:If A=1 or A=8
:-X->X
:If B=1 or B=16
:-Y->Y
:Output(A,B,"*
:End
for controlled movement just use ztrumpets example
also another thing about your menu yes the , is 62 but i figured something out the menu is not on the homescreen but on a seperate screen; dont know if that helps but it could

| Like they said the best to use would be the graph screen. It's easier to manage an output code then a text code. The best thing would be maybe to make a game where you select options of mensu to do things. Then once you have finished it, to move up to a game where you actually can move something and attack. I finished one recently, but haven't optimized it. Its on my brothers calculator so I don't see much of it. But it had magic, different weapons, levelling up, an inn, and a single enmy. I meant to add them in, but the program size grew to 4000+ bytes so I stopped. |

Okay, thx a lot for all your fast replies, this is really helpful, thank you :)
I understand some parts (in fact, I think I do), but I don't catch some others..
For example, with Ztrumpet's code :
[what I add is in red]
:8->A // I guess the variable A stand for the X axis and the "8" is because you make start the character (*) on the center, right ?
:ClrHome // If you had put this at first, would it be alright anyway ?
:Repeat K=105 //Loop until you press Enter, since the 105 is the ID for Enter key
:Output(1,A," //One Space. I'm not quite sure to understand what this means (1,A,")
:Repeat Ans //Loop until you press any key. Here, the Ans stands for the variable stored in K, such has 24 if I was going left ?
:getKey->K // Isn't it suppose to be before the Repeat Ans ? Probably not, since you made it and you are more advanced that I ^^"
:End // Why do you put a End in the middle of a prgm ?
:Output(1,A,"* // Still not figure out..
:A+(Ans=26 and A<16)-(Ans=24 and A>2->A // Ok, here, I'm totally lost..
:End
------------
Yeah I know, so much noob questions, but we have to begin somewhere, eh?
Quote: Ill help you but if this is your first game youve made you should probably start with something a little easier
Yeah, this is my first game, but I made a lot of prgm before. But don't worry, I won't jump on the big stuff right now, I just begin by making little stuff to understand every concepts, etc..

It's all because of you guys, thank you very much |

:ClrHome // If you had put this at first, would it be alright anyway ? Yes it would be fine as long as you dont put it in the loop
:Repeat K=105 //Loop until you press Enter, since the 105 is the ID for Enter key thats right
:Output(1,A," //One Space. I'm not quite sure to understand what this means (1,A,") the 1 in it is the location in rows so it would be first row or "Output(*row*,*column*,*display*" that should help you understand
:Repeat Ans //Loop until you press any key. Here, the Ans stands for the variable stored in K, such has 24 if I was going left ? yes
:getKey->K // Isn't it suppose to be before the Repeat Ans ? Probably not, since you made it and you are more advanced that I ^^" no it goes inside the loop to read the keypresses
:End // Why do you put a End in the middle of a prgm ? because there are two loops here this is the end of the Repeat Ans loop
:Output(1,A,"* // Still not figure out..
:A+(Ans=26 and A<16)-(Ans=24 and A>2->A // Ok, here, I'm totally lost.. this is the logic statement that makes it move with the keypresses and sets the area that it can go in a better way to do it would be max(16min(2(A+(ans=26)-(ans=24->A
:End
if you dont know what a loop is
While
For(
Repeat
these are example of loops

:A+(Ans=26)-(Ans=24
:Ans-((Ans=16)-not(Ans->A
My way is bigger (29 to 22 bytes), but I don't see how yours works. Did you forget commas?
(This one will wrap around the screen, but it's a lot more complex than the code I posted earlier.)
Here's the one I posted earlier:
:A+(Ans=26 and A<16)-(Ans=24 and A>1->A
Here's what is happening:
Value in Variable A is added to either a 1 (Ans, which has the keypress in it, equals 26, right arrow and A is not equal to 16) or a 0 (Ans dose not equal 26 or A is 16) and then (due to order of operations) (Ans=24 and A>1) is subtracted form it. The result is stored into A.
Here's a helpful page: http://tibasicdev.wikidot.com/deleted:boolean (it may be being deleted, but I like it better than: http://tibasicdev.wikidot.com/piecewise-expressions )

:8->A //
:ClrHome //
:Repeat K=105 //
:Output(1,A," //
:Repeat Ans //
:getKey->K //
:End //
:Output(1,A,"* // ..
:A+(Ans=26 and A<16)-(Ans=24 and A>2->A //
:End
The way it works is 1 is Stored to the variable A. The loop starts and The Character * is displayed on the first row, and the Ath column. Then, it takes a and if you pressed right and you have enough room, the * goes right. IF you press Left and have enough room, it goes left. |

Do you mean 8 is stored to A? |

Actually, the loop condition is correct. If it was a While loop, you would be right, but a Repeat loop works with Repeat K=105. If you use Repeat K≠105, then it will run through the loop once and end, not allowing movement, but only updating the screen with the *. |
