Maze Game Problem (Enemies)

[Moorky]

Hey Guys,

I made a Maze Game in Livecode but I have a problem because there are enemies in my Maze who can move and if you touch them you will respawn at the start.
Everything works fine but I don't know where I have to include the moving code of the enemie...
I know I have to include it in the Card Code but in which "command box" of it?
I tried to include the code it in "on openCard" but the program doesn't react after I start it the game (maybe overloaded).

Here is the code of the enemie moving:

Code: Select all

repeat forever
      put random(4) into Direction
      
      if Direction = 1 then
         set the top of graphic "enemie1" to the top of graphic "enemie1" - 3
         if top of graphic "enemie1" < 0 then
            set the top of graphic "enemie1" to 0
         end if
      end if
      
      if Direction = 2 then
         set the bottom of graphic "enemie1" to the bottom of graphic "enemie1" + 3
         if the bottom of graphic "enemie1" > the bottom of card "mycard" then
            set the bottom of graphic "enemie1" to the bottom of card "mycard"
         end if
      end if
      
      if Direction = 3 then
         set the left of graphic "enemie1" to the left of graphic "box" - 3
         if the left of graphic "enemie1" < 0 then
            set the left of graphic "enemie1" to 0
         end if
      end if
      
      if Direction = 4 then
         set the right of graphic "enemie1" to the right of graphic "enemie1" + 3
         if right of graphic "enemie1" > the right of card "mycard" then
            set the right of graphic "enemie1" to the right of card "mycard"
         end if
      end if
      wait 250 milliseconds
   end repeat

And if you want to see the whole Card Code:

Code: Select all

local Coins, Coin1, Coin2, Coin3, Coin4, Coin5, Coin6, Coin7, Coin8, Coin9, Coin10, Coin11, Coin12
local Direction

on openCard
   play "BGMusic.aif" looping
   put 0 into Coins
   put 0 into Coin1
   put 0 into Coin2
   put 0 into Coin3
   put 0 into Coin4
   put 0 into Coin5
   put 0 into Coin6
   put 0 into Coin7
   put 0 into Coin8
   put 0 into Coin9
   put 0 into Coin10
   put 0 into Coin11
   put 0 into Coin12
   put 0 into Direction
   
   repeat forever
      put random(4) into Direction
      
      if Direction = 1 then
         set the top of graphic "enemie1" to the top of graphic "enemie1" - 3
         if top of graphic "enemie1" < 0 then
            set the top of graphic "enemie1" to 0
         end if
      end if
      
      if Direction = 2 then
         set the bottom of graphic "enemie1" to the bottom of graphic "enemie1" + 3
         if the bottom of graphic "enemie1" > the bottom of card "mycard" then
            set the bottom of graphic "enemie1" to the bottom of card "mycard"
         end if
      end if
      
      if Direction = 3 then
         set the left of graphic "enemie1" to the left of graphic "box" - 3
         if the left of graphic "enemie1" < 0 then
            set the left of graphic "enemie1" to 0
         end if
      end if
      
      if Direction = 4 then
         set the right of graphic "enemie1" to the right of graphic "enemie1" + 3
         if right of graphic "enemie1" > the right of card "mycard" then
            set the right of graphic "enemie1" to the right of card "mycard"
         end if

So please tell me where I have to include the enemie moving in my card code or tell me if there is a mistake in the code of moving. (I started with LiveCode 2 Days ago.. I'm not experienced)

With best regards, Moorky.

Hi Moorky,
Welcome to the forum!

You are doing great for just 2 days!
Your idea of a "command box" is what we call a "handler" and you get to make your own handlers e.g. moveEnemy, dogBite, smellySocks. You can name them almost anything you like, don't worry liveCode will tell you when you try to use a "reserved word".

In your case it would be something like

Code: Select all

on moveEnemy
--your complete repeat loop---
end moveEnemy

For the openCard you would use

Code: Select all

on openCard
blah
blah
blah
moveEnemy
end openCard

Now your repeat forever is not really good form, get rid of the repeat and use something like this

Code: Select all

on moveEnemy
--remove repeat loop but keep the stuff inside of it---
send moveEnemy to me in 250 milliseconds
end moveEnemy

You see how that is working? It's calling itself wicked cool
To stop it in your close card you would put

Code: Select all

repeat for each line tLine in the pendingMessages
cancel item 1 of tLIne
end repeat

That "send" becomes a pending message that you must cancel out.

There is a bunch more that should be done as checks but I'll let you start with that.

Aww thank you so much!
