Blackboard GetVariable question

[pjohalloran]

Hi,

Hoping somebody could answer this tiny question i have about getting a variable value out of the Blackboard without having to cast from Object to the type of the variable. I must be missing something obvious here.

So GetVariable<T> returns type Variable.

Im having to do this:

1 2 3 4 5

public Foo MyFoo {     get {         return (Foo)this.Blackboard.GetVariable<Foo>("myFoo").value;     } }

When i’d actually like to do this using “T Variable::GetValue<T>()” (and it seems like its possible):

1 2 3 4 5

public Foo MyFoo {     get {         return this.Blackboard.GetVariable<Foo>("myFoo").GetValue();     } }

But Variable is a base class of Variable<T> and doesn’t have access to the GetValue<T>() call.

Is there something i’m missing here? Sorry probably there is but cant see it!

Probably we are meant to use “Blackboard.GetValue<T>(string key)” and avoid where possible getting variables directly?

Hello,

Yes, getting the variable value from the blackboard is better done with:

1 2 3

GetValue<T>(string key)

🙂

There is no good reason to get the “internal” usage ‘Variable’ object unless you want to store it.

Cheers!
