Understanding parameter pass..

[basketball4ever]

K... so in my code, i want whatever applies to player 1, apply to players 2,3, and 4 (aka: i'm doing snakes and ladders. thus, whatever happens to player 1, can also happen to player 2... like going up a snake or going down a snake.. or the position at which they're at:

code:

%S & L map2 proc slmap     % Going Up ladder 2 to 11     if pos1 = 2 then         delay (1000)         pos1 := 11         put "You just went on a ladder!" ..         map2pos1     end if     if pos2 = 2 then         delay (1000)         pos2 := 11         put "You just went on a ladder!" ..         map2pos2     end if     if pos3 = 2 then         delay (1000)         pos3 := 11         put "You just went on a ladder!" ..         map2pos3     end if     if pos4 = 2 then         delay (1000)         pos4 := 11         put "You just went on a ladder!" ..         map2pos4     end if     % Going Up ladder 6 to 9     if pos1 = 6 then         delay (1000)         pos1 := 9         put "You just went on a ladder!" ..         map2pos1     end if     if pos2 = 6 then         delay (1000)         pos2 := 9         put "You just went on a ladder!" ..         map2pos2     end if     if pos3 = 6 then         delay (1000)         pos3 := 9         put "You just went on a ladder!" ..         map2pos3     end if     if pos4 = 6 then         delay (1000)         pos4 := 9         put "You just went on a ladder!" ..         map2pos4     end if     % Going up ladder 7 to 21     if pos1 = 7 then         delay (1000)         pos1 := 21         put "You just went on a ladder!" ..         map2pos1     end if     if pos2 = 7 then         delay (1000)         pos2 := 21         put "You just went on a ladder!" ..         map2pos2     end if     if pos3 = 7 then         delay (1000)         pos3 := 21         put "You just went on a ladder!" ..         map2pos3     end if     if pos4 = 7 then         delay (1000)         pos4 := 21         put "You just went on a ladder!" ..         map2pos4     end if     % Going up ladder 10 to 25     if pos1 = 10 then         delay (1000)         pos1 := 25         put "You just went on a ladder!" ..         map2pos1     end if     if pos2 = 10 then         delay (1000)         pos2 := 25         put "You just went on a ladder!" ..         map2pos2     end if     if pos3 = 10 then         delay (1000)         pos3 := 25         put "You just went on a ladder!" ..         map2pos3     end if

...continued.


See how whatever i had to do for pos1 i had to do for pos2 and pos3 and pos 4 also... is there a way i can simplify this to make 400 lines into 100

Well, since the rules may apply to more than one player, why don't you use AND in your if statements. Also, why don't you have any elsifs in ur code?

[Bacchus]

use arrays and fors

[eNc]

Do you know how to use a case statement ? This may help you out a bit, also you can try setting a variable to the delay number so that you don't have to type as much, just some thoughts

[cycro1234]

Here's an example:


var mark : int
put "Enter a mark from 1 - 10: " ..
get mark
case mark of
label 9, 10 :
put "Excellent"
label 7, 8 :
put "Good"
label 6 :
put "Fair"
label :
put "Poor"
end case

as opposed to:

var mark : int
put "Enter a mark from 1 - 10: " ..
get mark
if mark = 9 or mark = 10 then
put "Excellent"
elsif mark = 7 or mark = 8 then
put "Good"
etc. etc.

Lol well i'm waiting for my whole thing to be simplified first. i figured i wouldnt use arrays already : P cos i'm too lazy. But i know using a simple parameter pass can fix up the whole code

[cycro1234]

And what, might I ask, is a parameter pass???

[basketball4ever]

parameter pass =
proc cycro (var:n:int) something like that :S ionno ms.**** said to use it : P

First setup your variables into an array, then you can make a procedure like this:

code:

proc slmap (player : int)     % Going Up ladder 2 to 11     if pos (player) = 2 then         delay (1000)         pos (player) := 11         put "You just went on a ladder!" ..         map2pos (player)     end if end slmap

That shortened your first 4 if statements into 1. I'll leave the rest up to you
Once you have that you can call ur procedure for each player by using a for loop:

code:

for i : 1 .. 4     slmap (i) end for

lol as i mentioned... i'm not an array user : P

You should be. If you don't know how to use arrays, read one of CompSci.ca's tutorials. They can be found in the Turing Tutorials section. You can also do a search.
Arrays are easy to learn, and incredibly useful. You'll be glad you learned them, when you do.
