Scratch

Thanks, I was sort of on to that, what I really need to do is have each sprite wait until the main sprite has interacted with the prior sprite before moving on to the next one and so on through all of them. And then I would like one of the other sprites to appear. Sort of like interacting with shuffled flashcards in real life.

Yeah in random order, and let the main sprite interact with them one at a time.

Thanks very much for your help.

I think you might be able to do something where the master sprite sends out a request message to all the other sprites.  When the other sprites get the request, the ones that haven't already been used wait a random number of seconds and then the first one that responds is used next.  This would repeat until all the sprites had been used. 

This would be a fairly complex bit of coding as it would require a couple of variables to keep track of who has been used and when a request has be fulfilled and so on.  Let me know if you want me to take a whack at it!

Or you could do it my way:

Make a variable called
[blocks]
<{ random }>
[/blocks]
then on the stage put this script:
[blocks]
<when green flag clicked>
<broadcast[ startrand ]>


<when I receive[ startrand ]>
<set{ random }to( <pick random( 1 )to( 12 ) )>
<if><( <{ random }> <=> 1 )>
<broadcast[ spr2 ]>
<end>
<if><( <{ random }> <=> 2 )>
<broadcast[ spr3 ]>
<end>
[/blocks]
Etc. until you have an if statement for everything from 1-12 and a broadcast thing for everything from 1-12.

Then, øn each sprite that must interact with the main sprite, put the respective code. For example if it is sprite2, then use this script:

<when green flag clicked>
<hide>
<go to x   starting spot )y   starting spot )>

<when I receive[ spr1 ]>
<show>
<wait until><touching[ main sprite ]>
<broadcast[ startrand ]>
<hide>

and for sprite3, use:

<when green flag clicked>
<hide>
<go to x   starting spot )y   starting spot )>

<when I receive[ spr2 ]>
<show>
<wait until><touching[ main sprite ]>
<broadcast[ startrand ]>
<hide>
[/blocks]
etc. until you have that on every sprite. This should work because if it gets the same random number twice, then it would already be touching the main sprite and would then pick another random number. It might flash for a small amount of time on occasion, but otherwise it should work fine unless your 'interaction with main sprite' is something other than touching it.

Ok, so I combined my system of my main sprite correctly messaging my other sprites, but how do i get the random generator to only pick each sprite once?

A clunky method is to choose a random number for your first sprite. then put your method of choosing arandom number for your second sprite into a "reapeat until not = "first sprite" loop.

Then for the 3rd sprite you have "repeat until not=first sprite or second sprite"

etc.

Its a very clumy way of doing it, mind you.

Well, with my method, if it does pick the sprite twice, then it is already touching the first sprite and should only flash once. Once all of the sprites have been picked, then you may have a little flashy problem.
