i might already asked that question (but then i abandoned this
and today get back to it)

i need extremally simple schem for coding paragraphs

in main game part i got two callbacks one is in

OnDraw()
{
draw_current_screen(); //<-- its callback pointer
}

OnKeyPressed(int key)
{
last_key=key;
current_key_handler(); //<-- thios is callback for keys
}

so in game i need to provide a lot of routines for drawing text
and a lot for handling keypresses

it currently look like that


start()
{
text("youre in the middle of the woods, chose what to do:");
text("1) go north");
text("2) go south");
}

start_()
{
key('1', go_north, go_north_); //this function just set callbacks to
new state
key('2', go_south, go_south_);
}

and so on i could produce hundred paragraphs of this way and it will
make a net of connected parragraphs


But it somewhat annoys me as it still seem to moe to be
to complicated and i needed to be as simple as its possible


how i could sipmplify it? note i could replace function key
by some makro to write KEY(1, go_north) probbaly
(i write probably as i dont use macros in c at all and even dont
remember how to define them, but still its maybe annoying to have 2
routines for each paragraph

isnt it possible to write this something like


start()
{
text("youre in the middle of the woods, chose what to do:");
text("1) go north"); KEY(1, go_north);
text("2) go south"); KEY(2, go_south);
}

????

as i could writhe a tons of this paragraphs (thinking about writing big paragraph game) it would simplyfy a hours of typing

You have a set of situations. Each situation involves a place and possibly
some state information. For each place you need a paragraph of text that
you need to write. You also need a (hopefully short) paragraph of text
for each possible value of each state variable.

The program is simple. The function start does not write anything.
It just initializes the situation variables and calls the function
that displays texts as required by the situation variables. On key
input update situation variables according to the key and call the
same function as start does.

its not an answer to the question..question it hovever maybe not easy as
it needs some back focus i think

the problem is i got 2 entries one is a tree for key kals and secont
separate is a handler for drawings

i think to make it simple i should only write the keys based tree,
but then o cannot draw text from there and would need probebly
set some pointers form text lines where drawing part wopuld just use


im not sure if it is worth but probably

it doesnt seem to be answer to my question ..what i say thet paragraph
game (paragraph game is just a set os paragraphs/screens of text where
below yu got options to chose (like 2 or 5) and you jump to another
paragraphs

in dos c it could be done like this


start()
{
clear_screen*(;
text("youre near river and see the boat");
text("1. go inside the boat");
text("2. go to the forest");

k =getch();
if(k=='1') boat()
if(k=='2') forest()

}


boat()
{
clear_screen*(;
text("you sit in boat you swim 1. down the river 2. up the river");

k =getch();
if(k=='1') swim_down_river()
if(k=='2') swim_up_river()

}

forest()
{
clear_screen*(;
text("youre in the forest 1. walk north 2. walk east");
}


but in windowsc you got two roots - event handlers and you need to draw
text in one and take keys in another


notabene it seem maybe that DOS way witch GETCH() is woser this getch
just could ba generalized to pop any event that occurs

it doesnt seem to be answer to my question ..what i say thet paragraph
game (paragraph game is just a set os paragraphs/screens of text where
below yu got options to chose (like 2 or 5) and you jump to another paragraphs

Which is exactly what ACS did.

Only it didn't create a lot of code for each of the screens, but built a fairly simple datastructure for the game.

As I remember, it created an array of node of a size gotten from the
begining of the file.

Each node had a pointer to the string that was printed when you reached
that node, and a list of keys you could press, and what state those took
you to.

I seem to remember it having a way to mark some options conditional on having/not having a given object that you might find on the way.

in dos c it could be done like this

start()
{
  clear_screen*(;
  text("youre near river and see the boat");
  text("1. go inside the boat");
  text("2. go to the forest");

 k =getch();
if(k=='1') boat()
if(k=='2') forest()

}

boat()
{
  clear_screen*(;
  text("you sit in boat you swim 1. down the river 2. up the river");

 k =getch();
if(k=='1') swim_down_river()
if(k=='2') swim_up_river()

}

forest()
{
  clear_screen*(;
 text("youre in the forest 1. walk north 2. walk east");
}

For a text only game making one's own engine is as easy as to find
a good enough one (unless one already has one).

Yes, if you don't need any other input.
But you have to choose whether you first branch by the input character
and then check the situation to determine what to do with htat character
or brach by the situation and then check the character to determine
what to do with the situation.

make a net of connected parragraphs


But it somewhat annoys me as it still seem to moe to be
to complicated and i needed to be as simple as its possible


how i could sipmplify it?  note i could replace function key
by some makro to write  KEY(1, go_north) probbaly
(i write probably as i dont use macros in c at all and even dont
remember how to define them, but still its maybe annoying to have 2
routines for each paragraph

isnt it possible to write this something like


start()
{
  text("youre in the middle of the woods, chose what to do:");
  text("1) go north"); KEY(1, go_north);
  text("2) go south"); KEY(2, go_south);
}

????

as i could writhe a tons of this paragraphs (thinking about writing big
paragraph game) it would simplyfy a hours of typing

This sounds very much like would be solved with the Adventure
Construction Set. That wasn't in C, but should be able to be
translated to it. Note, the "map" wasn't done in code, but data.

For a text only game making one's own engine is as easy as to find
a good enough one (unless one already has one).

The point is that rather that writting a lot of code for all the
routines, and repeating yourself over and over with boiler plate.

You write one simple engine, and "program" the game with data-structure.

My understanding is that the ACS wasn't written in his prefered
language, and so he might want to recode it. but its program structure
solves the problem he was having of need a lot of code which does
basically the same thing.
