typecasting ;(

Dark[NSF] · 5th Oct 2003, 05:55 PM

How would I get my custom PlayerController class from Pawn?

Pawn.Controller(nsfplayer).blah blah?

Controller(nsfplayer.pawn).blah blah?

I'm lost, I would love some help

You've got it flipped. it's:

nsfplayer(Pawn.Controller).foo;

nsfplayer(Controller).foo;

etc.

Typecasting always works like this:

ClassToTypecastTo(ObjectToTypecast).PropertyToAccess

or

ClassToTypecastTo(ThingToGetObjectFrom.ObjectToTypecast).PropertyToAccess

Just need some little explanation.
I got two classes. One is SC_Crystal and the other SC_Blue_Crystal. The blue crystal one is a subclass of crystal. and two references. one called just crystal, and the other blue_crystal.
no i take a for loop through the navigiationpointlist and check if there is one of my crystals or blue ones

Code:

[...]
// NP is the reference to NavigationPoint
// if...found crystal -> works
Crystal = SC_Crystall(NP);

// if...found blue crystal --> works
Blue_Crystal = SC_Blue_Crystal(NP);

// if found blue crystal (another bsp) -> wont works
Blue_Crystal = SC_Crystal(NP);
[...]

Can i only cast objects which belongs to their reference? cause the third cast doesn´t work as shown in the comment.

Just want to know why.

The cast itself works well, the compiler moans about a different problem: You can only assign objects of the same class or a sbuclass to a variable.
Your Crystal variable can hold any SC_Crystal and any subclass of it, like SC_Blue_Crystal, but you can't assign an SC_Crystal to the Blue_Crystal variable because it's not a subclass of SC_Blue_Crystal.

ok, thats clear to me. but in the first tries i also tried to set Crystal = SC_Blue_Crystal(NP) and it even gives me an access none. weird, isn´t it?

That statement can't give any Accessed Nones directly, only if NP isn't an SC_Blue_Crystal. If NP is an SC_Crystal (i.e. not an SC_Blue_Crystal) the typecasting result is None, which gets assigned to Crystal.
