Calling a script from AngelScript

(1/2) > >>

wladimiiir:
Let's say, I have string with the value of "myCoolModule@mySuperCoolFunction". Is there a way how to call the script function that is represented by this value?
I could not find any useful info that this could be done from AngelScript. The only way, which comes to my mind, is to call DLL with C++ function which would call the AngelScript function in return.

Any ideas? Thanks.

Not counting .dlls... hmm, let the workarounds flow~

Server-side you can use time events to run function, with zero delay. Of course, you can't get return value of the function then, plus you'll be limited to int[], uint[], and everything what can be bytepacked as arguments.
Client-side you can use RunServerScriptUnsafe() and pass your string - server's job is to call RunClientScript() using your string as function argument. Same limitations as above.

;D

wladimiiir:
Yeah, I am aware of those options. :)

What I am trying to do is to call fix_ functions in fix_boy.fos, basically, as I am remaking the FixBoy on client side, calling my unsafe_fix functions on server side, which should try to call script functions defined in CraftItem.

So none of this can be used, because they use different arguments. :(

Ghosthack:
Sounds like you have to do a call to a wrapper function with a string argument which can then call the appropriate function, you're able to reduce the amount of boilerplate code by using macros for definitions and calls.

Got bored with own bugs, so why not create some for others :D


--- Code: ---#define valid#(ptr) (@ptr!= null)

funcdef int fixFunc( Critter@ player, int state, CraftItem& craft );

class FixData
{
    string Name;
    private fixFunc@ func;

    FixData( string& name, fixFunc@ func )
    {
        this.Name = name;
        @this.func = func;
    }

    int Call( Critter@ player, int state, CraftItem& craft )
    {
        if( valid(func) )
            return( func( player, state, craft ));

        return( -1 ); // error mark
    }
};

array<FixData> Wrapper;

void InitFixboy()
{
    Wrapper.insertLast( FixData( "fix_silly", @fix_silly ));
    Wrapper.insertLast( FixData( "fix_dummy", @fix_dummy ));
}

int fix_silly( Critter@ player, int state, CraftItem& craft )
{
    return( 1207 );
}

int fix_dummy( Critter@ player, int state, CraftItem& craft )
{
    return( 1337 );
}

void unsafe_fix( Critter@ player, int craftItem, int state, int, string@ func, array<int>@ )
{
    int result = -1; // error mark

    if( valid(func) && func.length() > 0 )
    {
        for( uint w=0, wLen=Wrapper.length; w<wLen; w++ )
        {
            if( Wrapper[w].Name == func )
            {
                CraftItem@ craft = GetCraftItem( craftItem );
                if( valid(craft) )
                    result = Wrapper[w].Call( player, state, craft );

                break;
            }
        }
    }

    Log( "RESULT "+(valid(func)?func:"<invalid>")+":"+result );

    if( result == -1 )
    {
         // error handling
         return;
    }

    // further result processing
}

#ifdef __ASCOMPILER
void test()
{
    InitFixboy();

    unsafe_fix( null, 0, 0, 0, "fix_silly", null );
    unsafe_fix( null, 0, 0, 0, "fix_dummy", null );
    unsafe_fix( null, 0, 0, 0, "fix_incorrect", null );
    unsafe_fix( null, 0, 0, 0, null, null );
}
#endif

--- End code ---

So yeah, pure AS example; hope it's clear enough for you.

All manual work left is to fill InitFixboy() with all of yours fix_ functions; sadly can't see a way to automate it. I also used Critter@ instead of Critter& for test purposes, so that one need fixing too. Can still be improved, for example by scrapping string@ func usage and relay on CraftItem::Script instead - again, it's done that way or ASCompiler would get mad.

As i understand you want to avoid .dlls [where whole thing would be much easier and shorter] for maximum portability, or is there any other reason?
