About struct's extension : actually a "little" useless

[Zamy]

Little example:

struct BaseStruct
{
    var bool IsUsed;
    structdefaultproperties
    {
        IsUsed = false
    }
};

struct AnotherStruct extends BaseStruct
{
    //add some other stuffs
};

var BaseStruct A;
var AnotherStruct B;

function SetUsed(out BaseStruct S)
{
    S.IsUsed = true;
} 

function MyFunction()
{
    SetUsed(A); //ok
    SetUsed(B); //error
}

Here's the error:

Error, Call to 'SetUsed', parameter 1: Type mismatch in Out variable

Seriously, it's like extending a class without getting parent's methods and properties: totally useless.
And i find the struct extension very useful in many situations.

Hmm… can you typecast B to the BaseStruct when calling that function?

[Zamy]

using

SetUsed( BaseStruct(B) );

result:

Error, Bad or missing expression for token: MyFunction, in Call to 'BaseStruct', parameter 1

(p.s. : Ty for your reply, Crusha)

Sorry for the bump, any news/solution about this?
I find them extremely useful...

Using objects instead of structs would solve this issue.
