Array looping within an action plugin

Hi all,

I'm amending the socket.io plugin again and looking for some advice on actions:

acts.ScriptName = function (params)

{

// do something

};

So I have an array called dataStack[].

I'm pushing objects into it something like this:

event = new instance.Event;

event.name = blah; //String

event.data = blah; //JSON

event.time = Date.time(); //Time in ms

dataStack.push(event);

What I want to do is expose the looping through the array to C2.

Something like a For Each Element action...

How does this work and tie in with the loopIndex exposed to loops within C2?

Many thanks for some pointers...

"For Each Element" is a kind of condition in array plugin, you could find it in runtime.js in array plugin.

Many thanks but I couldn't see it...then discovered it's an Event not an action. Are we able to write events?

Failing that, I could do a LoadArray type expression? Although a bit confused about the arrays in C2, do they take objects?

1. yes, 3rd plugin could have condition (event)

2. expression only accepts number or string.

Many thanks for your speedy help!

I found the function. It accepts a parameter 'dims' (dimension of array to loop through) and within those loops calls another function using:

this.doForEachTrigger(current_event);

Which is:

     instanceProto.doForEachTrigger = function (current_event)

     {

          this.runtime.pushCopySol(current_event.solModifiers);

          current_event.retrigger();

          this.runtime.popSol(current_event.solModifiers);

     };

What do these 3 lines of code do? I see a push and pop but not sure where the code for these functions are.

Thanks for any help as always!

It just re-triggers current event (condition). You could trace it by insert a "debugger" line.

Thanks, I've updated the Socket IO plugin now to feature this event capturing and looping and works like a charm.

Need to do some more testing with my example game and publish soon enough.
