how to switch turns in a two player game

[kesh17aki]

hi i would like to ask how to code a two player game,, i have a problem regarding switching of turns in my game.. i created a game just like snake and ladders. i have two players, since player 1 always starts first, how would i take player 2's turn.. like after player 1's turn...

[kesh17aki]

i have here my code for my dice loop

Code: Select all

on mainEventLoop
   // Continue this loop until gRun is set to false.
   lock screen
   --enableDisable
   animateDice // Animate the dice
   unlock screen
   // Delay further execution by 50 milliseconds.
   // But allow button clicks to be processed.
   if gRun is true then
      send "mainEventLoop" to me in 5 milliseconds
      
   end if 
   if gRun is false then
      movePone
   end if
end mainEventLoop

i have here, only player 1 will move. movePone is player 1's move
how and where will i put the switching of turns of both players?

Hi kesh17aki,

1. welcome to the forum!

2. Since I have no idea about your game, here some quick thoughts:
use e.g. a global variable which only holds 1 or 2 to indicate the current player.
Use this to identify the current player in your script(s).

"Initialize" it maybe on openstack and/or when you start a new game:

Code: Select all

...
global gCurrentPlayer
put 1 into gCurrentPlayer
...

Then after every action for the (first) player have been finished, switch the global like this:

Code: Select all

command SwitchPlayers
   global gCurrentPlayer
   if gCurrentPlayer = 1 then
      put 2 into gCurrentPlayer
   else
    put 1 into gCurrentPlayer
  end if
end SwitchPlayers

When starting a new game, just:

Code: Select all

...
global gCurrentPlayer
put 1 into gCurrentPlayer
...

Get the picture?

yes Klaus, thank you for the help its working

[jmburnod]

Hi kesh17aki,
I remember Klaus recommended me to use numtochar(1) as delimiter.
I'm a good (old) boy and I do it with success. Each time i don't hear the voice of Klaus about itemdel, i get a mistake.

well its ok. i got it all working. but my problem is how to reset the game. i have two "Winner" cards for each players. and it has a play again and quit buttons.. my problem is if i click play again, the whole game wont reset. so i would like to reset them, like put empty into their field names, return the players into its current position w/c is their starting area. i'm still new about this and i would like to learn more about livecode. well anyway, heres the code for the "Winner" card of player 1.

Code: Select all

global pOnename,theCurrentLocation,theCurrentLocationTwo
local tButtonName,tControl
on openCard
    put pOnename into fld "pWin"
end openCard

on mouseUp
   
   set the itemDelimiter to space
   put the short name of target into tButtonName
   if item 1 of the name of target is "button" then
      if tButtonName is "plyAgn" then
         resetGame
      else if tButtonName is "rollOnOff" then
         gCurrentPlayer
      end if
      end if
end mouseUp

command resetGame
   set the itemDelimiter to space
   repeat with tControl = 1 to the number of controls of me
      set visible of control tControl to true
   end repeat
   put empty into pOnename
   put empty into pTwoname
   put 141,669 into theCurrentLocation--current location of player1
   put 275,675 into theCurrentLocationTwo
   go to card "Choose Player"
end resetGame

Hi kesh17aki,

... so i would like to reset them, like put empty into their field names...

???
...
put empty into field "whatever field you need to empty!!!" of card "another cardname, which is probably not the current card"
## Use OF CD XY (of stack yz) if the control you are addressing is not on the current card!
...
## Or did I miss something?

... return the players into its current position w/c is their starting area...

Of course you need to store the initial position of the players BEFORE you start the game the first time!
...
## Example:
global gOldPlayerPosition1, gOldPlayerPosition2
set the loc of btn "player 1" to gOldPlayerPosition1
set the loc of btn "player 2" to gOldPlayerPosition2
...

thanks. now i got it all working do you have any codes for 1 player vs computer? coz im planning to add another feature for this game, tnx

[Simon]

Since the game is like snakes and ladders the random number from the dice tells you how many steps the computer player can take so that part is easy. You will have to know the location of all the squares you can move to and which ones are snakes and which ones are ladders to move the player to the correct position.
All of that removes any "strategy" from the game, much easier to program.

yes i know,, but in my part being a newbie.. i still need help from the experts like you hope you can help me,
