reading states from other actors

pospi · 13th Mar 2004, 03:22 AM

Hey all,

I just need some quick help...

I have the usual weapon class with its two classes for primary and secondary fire. I'm wondering if it's possible to read a state from the secondary fire class actor into the primary fire class actor, and how to do this?

Also if anyone knows of a good resource on referencing actors, that would be great cos i don't really know what i'm doing with it. I wish it was as easy as referencing classes!

cheers

FireMode[m] = Spawn(FireModeClass[m], self);
In PostBeginPlay of Weapon shows that the FireMode array holds the spawned FireClass
GetStateName() function tells you the state of any actor

Every variable that holds a spawned class is an Actor reference. It is easier than referencing classes.

Hooray!

however, if this is the case i will only have access to that variable from within the weapon class.. how do i reference from the other fire class?

I remember seeing somewhere the function to return an actor's owner, or parent.. i'm not sure of the correct terminology.. but anyway can i do something like

Code:

this.owner.FireMode[1].GetStateName();

to return the state from the other fireclass?

I guess i just need to know the correct function or variable to return an actor's owner, but i cant find the damn thing no matter where i look (:

cheers

Type casting my also be an issue. Remember that Owner is an Actor/Object (I can't recall) and it won't know what FireMode[x] is. So something like Weapon(Owner).FireMode[x].GetStateName(); is required.

Typecasting/Referencing is quite a hard concept to explain, and it is really an understanding of OOP which really helps here. I think the Wiki has a good explanation on what it is.

the firemode has a variable weapon
so it would be
weapon.firemode[x].getStateName();

This variable is a reference to the weapon which is a real actor in the level.
Which actor contains in turn other reference to other existing actors.

awesome! that seems to work, thanks very much.

and yeah, i remember typecasting from java and C. it gets horrendus pretty quickly

In Uscript typecasting is pretty easy, just remember to test that it is actualy the class you are casting to, like this:

if(Weapon(AnActor)!=none)
