Sending a variable from a custom script back to playmaker [SOLVED]

[justifun]

I see how to send a variable from a FSM to a custom script, but how do you send a variable from within a script back to an FSM?

for example, i have a script that reads the text from a text file and stores it as a string.  how do i get playmaker to pick that up?

thx

Hi,

 First you need to have a reference to the fsm component in your script

declare a public var:

Code: [Select]

public PlayMakerFSM theFsm;

then you can use:

Code: [Select]

theFsm.FsmVariables.GetFsmBool("My bool var").Value = false;

If you have more than one fsm component attached to your gameObject, It can become confusing so I suggest another approach to the public var. Instead, reference the name of the fsm you want to access and use in the awake the following script:

Code: [Select]


PlayMakerFSM[] temp = GetComponents<PlayMakerFSM>();
foreach (PlayMakerFSM fsm in temp) {
if (fsm.FsmName == "the fsm I want to work with"){
theFsm = fsm;
break;
}
}

This would be the basic approach.

Hope this helps,

Bye,

Sorry Jean i'm still confused.

The part where you say theFsm.FsmVariables.GetFsmBool("My bool var").Value = false;

Isn't that simply reading the variable ("my bool var") value from the FSM ?

I want send a variable from a custom script so that the fsm can pick it up and use it.

For example here's a line from my code

var text : String = System.IO.File.ReadAllText("C:\\testread.txt");

How do i pass the variable "text" back?

Is there such a thing as "SetFSMString"?

EG:

Code: [Select]

public PlayMakerFSM theFsm;
var text : String = System.IO.File.ReadAllText("C:\\testread.txt");
theFsm.FsmVariables.SetFsmString("my text string").Value = text;
thx for your help.

Sorry, I was doing too much in one line, here how it goes:

Code: [Select]

FsmString myFsmString = theFsm.FsmVariables.GetFsmString("My string var");


myFsmString.Value = "Hello";


GetFsmBool() actually return the Fsm variable, not that value it contains, the value it contains is then accessed by .Value, that you can set or get.

Hope this is clearer now

 Bye,
