Im very new to qbasic and have just learned a few simple bits here and there.
To help myself get better im currently trying to make a mini TEXT only rpg type thing, basically a small shopping mall type simulation, where i can walk around and look in shops (kinda sad but i need to learn this) :bounce:
I have managed to programme all the 'rooms' of my mall but making commands specific to a certain room is causing quite a few problems for me. In general, north east south west for each room was easy i used the if and then commands.
I want to set specific key promts in rooms like shops though:
eg: buy 'item' in a shop, which i want only to be applicable in that particular room and nowhere else. (if this makes sense)
can anyone help me?
im very new to all this... :-? so im a bit slow at the minute hehe
Hmmm, just use IFs in combination with what is called "flag variables". These kinds of variables store numeric values that have an useful meaning. For example, you can have a flag to store which kind of room you are, for example, let's say
Code:
' the RoomType% variable will equal...
' 1 If you are in a corridor
' 2 If you are in the greengrocer's
' 3 If you are in the toy shop
' 4 If you are in the boutique
' (err... to name a few)
RoomType%=4
You only have to set it correctly for each room, and just make an IF. I don't know what kind of data structure you are using to store the room data, or maybe if you are hard-coding them with PRINTs and GOTOs (I would not do that!)...
In Sum, I don't know if I am helping you, mostly because I don't know how you are implementing your game
ok i kinda understand now but im still too crap to put that into use, iv been programming about 3 days hehe and it aint goin all to well never done it before do i set these room types as an array, and is there a way i can customise each room type somehow after the array setting:-s sorry if i make no sense
The best thing is to have everything inside a data structure. Check for TYPE commands. You can look:
1. In QB help.
2. In tutorials (found in this site)
3. Do a SEARCH in this forum for "TYPE" and you'll find tons of info in past posts.
hey there
Umm, let's see.
Let's see if I got this right: So are you using a command menu such as
Where would you like to go?
1-> Shoe Store
2-> Software Etc
(and so on)
_ <-- the input
?
Oh i think I get it... so you can type in southeast and it would take you southeast, right? Well, if you are in a certain shop you can use the INKEY$ variable to program keys that would only work for a certain area
what you should do is create a DO LOOP UNTIL loop where the user can input a key. You could have the movement instead of typing southeast northwest and so forth just be a diagonal pad something along the lines of
q w e w is up, q is upleft (northwest) e is upright (northeast)
a s d and soforth...
z x c
so your program could look something like this
Code:
DO
PUSH$ = INKEY$
'use the above line because it is more responsive than just inkey$
'alone. For some reason there is a delay when you use an if inkey$
'statement, but if you use a push$ (when push$ = inkey$) it will
'work.
IF PUSH$ = "w" THEN WAY$ = "north" 'WAY$ is the clarifying var.
IF PUSH$ = "s" THEN WAY$ = "south"
IF PUSH$ = "a" THEN WAY$ = "east"
IF PUSH$ = "d" THEN WAY$ = "west"
IF PUSH$ = "q" THEN WAY$ = "northwest"
IF PUSH$ = "e" THEN WAY$ = "northeast"
IF PUSH$ = "z" THEN WAY$ = "southwest"
IF PUSH$ = "c" THEN WAY$ = "southeast"
'to create other commans for a certain shop you should use
'something like a variable called place$ that would tell what shop
'you are in...
IF PLACE$ = "shoes" AND PUSH$ = "b" THEN GOTO BUYINGSHOES
'and create a label called buyingshoes: that would have the buying
'process in it.
LOOP UNITL PUSH$ <> ""
'loops until a button is pushed....... you may want to change this to
'be until push$ = "a" or push$ = "c" and go through all the choices
'this is a little painstaking but it would help safeguard your
'program from glitches.
I got to go, email me @

if you need more help than that, but I think that is fairly seflexplanetory. (did I spell that right?!
)

Don't use "IF" in such cases. Better take "Select Case". Here ya go:
Code:
Key$=IINKEY$
SELECT CASE Key$
CASE "W": Way$ = "North"
CASE "S": Way$ = "South"
CASE "A": Way$ = "West"
CASE "D": Way$ = "East"
END SELECT
"Select case" is times faster than "if" if you want to compare a variable not only one time with some values.
Thanks, I didn't think of that one. :lol:
