[SOLVED] GetProperty won't give option to store property
« on: March 17, 2012, 09:24:21 PM »
Hi everyone,

I am a little stumped. I have a custom Entity component (monobehaviour) and am using GetComponent in my FSM to store that component in a variable. That part is working fine. However, I'm then trying to access a public bool on that component called isAlive from that stored object.

When I add the GetProperty action to my state, it allows me to select that variable for the object, and it populates the list of properties correctly, but if I select any of the Entity class properties, the store variable line disappears from the action inspector. However, if I go down to the inherited subsection, and chose one of the inherited properties (from monobehaviour) suddenly I can store them again.

Am I misunderstanding how GetProperty is supposed to work? I could have sworn you could use it to store standard, public data-types from custom components, but maybe I'm crazy. Thanks for any help you can give.

-Sean

UPDATE:

This only happens when I'm accessing my Entity class as an FSMObject variable. If I just drag an entity component onto the action, it works fine. If I try to use the stored object, the Type updates correctly (and says "Entity") but I lose the store ability.

Sounds like a bug... Can you send me your Entity component?

Does this only work with Properties as the name implies or should it work with any standard field type???

If I make a monoBehaviour with a single float field, I get the same error.
But if I switch it to a float get set property the store variable option comes back.

Windows7 pro x64
Unity 3.5.1f2
Playmaker 1.3.3 (17412)

may you post an example?
because i have this (tried with the variable public, private, protected and nothing):

   Transform parent;
   public Transform getParent(){
      return Next;
   }
   
   public void setParent(Transform lNext){
      Next = lNext;
   }

Thanks

You need to make a Get Set style property... not a method (notice the parenthesis "()" on the method ):

Code: [Select]
// Method that returns a type of Transform
public Transform setParent()
{
}

A property looks like this

Code: [Select]
public TYPE NAME
{
    get {return VARIABLE;}
    set {VARIABLE = value;}
}



Sounds like your trying to access the transform component of your gameObject.
General rule of thumb is to make a private field that is controlled through a public property, so
First make a private field ( usually the same name as the property but with an "_" before the name)


Code: [Select]
private Transform _myTransform;
Then the property:

Code: [Select]
public Transform myTransform
{
    get { return _myTransform;}
    set { _myTransform = value;}
}


Notice In my example I've changed your name from "transform" to "myTransform",
the reason being that transform is a built in property of Unity that exists on all gameObjects already.
If you specify yours with the same name you will override the builtin one.

Properties are a great way to manage your class's variables that allow a lot more control than simply setting a value,
I would strongly recommend reading up on them, espesially since this is how to get values in and out of playmaker.

Let me know if that all makes sense.

Have you tried this in 1.4.0? There were some fixes for FsmObjects and Get/Set Property...

Just updated to 1.4 and the get property now works with fields, so ddfire you can now access your fields directly rather than going through a property.

Thanks for the update.
