How to acces a variable or function, from one a class to another one

[Neongho]

I've got a variable in a class wich extends from trigger from basically actor , called taken , that basically when you use that object it turns into true.

see the class here

class

class UsableActor extends trigger
placeable;

var bool taken;
var() const string Prompt;
var bool IsInInteractionRange;

event Touch(Actor Other, PrimitiveComponent OtherComp, Vector HitLocation, Vector HitNormal)
{

    WorldInfo.Game.Broadcast(self, "you touch");

    super.Touch(Other, OtherComp, HitLocation, HitNormal);
   `log( "Hello, world!" );
    if (Pawn(Other) != none)
    {
        //Ideally, we should also check that the touching pawn is a player-controlled one.
	PlayerController(Pawn(Other).Controller).myHUD.AddPostRenderedActor(self);
	IsInInteractionRange = true;
    }
}

event UnTouch(Actor Other)
{

   WorldInfo.Game.Broadcast(self, "you no touch");
    super.UnTouch(Other);

    if (Pawn(Other) != none)
    {
	PlayerController(Pawn(Other).Controller).myHUD.RemovePostRenderedActor(self);
	IsInInteractionRange = false;
    }
}

simulated event PostRenderFor(PlayerController PC, Canvas Canvas, Vector CameraPosition, Vector CameraDir)
{
    local Font previous_font;

    super.PostRenderFor(PC, Canvas, CameraPosition, CameraDir);

    WorldInfo.Game.Broadcast(self, "you touch");
    previous_font = Canvas.Font;
    Canvas.Font = class'Engine'.Static.GetMediumFont();
    Canvas.SetPos(100,100);
    Canvas.SetDrawColor(0,255,0,255);
    Canvas.DrawText(Prompt); //Prompt is a string variable defined in our new actor's class.
    Canvas.Font = previous_font;

}

function bool UsedBy(Pawn User)
{
    local bool used;
    used = super.UsedBy(User);
    if (IsInInteractionRange)
    {
    taken=true;
     WorldInfo.Game.Broadcast(self, "MESSAGE HERE");
        //If it matters, you might want to double check here that the user is a player-controlled pawn.
        PlaySound(SoundCue'A_Weapon_BioRifle.Weapon.A_BioRifle_FireImpactFizzle_Cue'); //Put your own sound cue here. And ideally, don't directly reference assets in code.
        return true;
    }
    return used;
}






DefaultProperties
{
  begin object Name=Sprite
        HiddenGame=true
	HiddenEditor=true
    end object

    begin object class=StaticMeshComponent Name=MyMesh
	StaticMesh=StaticMesh'NodeBuddies.3D_Icons.NodeBuddy__BASE_SHORT'
    end object
    Prompt="hello";
    CollisionComponent=MyMesh
    Components.Add(MyMesh)
    bBlockActors=true
    bHidden=false
   taken=false
}

And that variable i want to use it in the pawn class of my game

class GladiatorPawn extends Pawn;

var() const DynamicLightEnvironmentComponent LightEnvironment;
var() const int IsoCamAngle;
var() const float CamOffsetDistance;
var() const Name SwordHandSocketName;
var() const archetype MeleeWeapon SwordArchetype;
var AnimNodePlayCustomAnim SwingAnim;
var float CamPitch;
var bool taken;

simulated event PostInitAnimTree(SkeletalMeshComponent SkelComp)
{
    super.PostInitAnimTree(SkelComp);

    if (SkelComp == Mesh)
    {
        SwingAnim = AnimNodePlayCustomAnim(SkelComp.FindAnimNode('SwingCustomAnim'));
    }
}


simulated function bool CalcCamera(float DeltaTime, out vector out_CamLoc, out rotator out_CamRot, out float out_FOV)
{
    local Vector HitLocation, HitNormal;

    out_CamLoc = Location;
    out_CamLoc.X -= Cos(Rotation.Yaw * UnrRotToRad) * Cos(CamPitch * UnrRotToRad) * CamOffsetDistance;
    out_CamLoc.Y -= Sin(Rotation.Yaw * UnrRotToRad) * Cos(CamPitch * UnrRotToRad) * CamOffsetDistance;
    out_CamLoc.Z -= Sin(CamPitch * UnrRotToRad) * CamOffsetDistance;

    out_CamRot.Yaw = Rotation.Yaw;
    out_CamRot.Pitch = CamPitch;
    out_CamRot.Roll = 0;

    if (Trace(HitLocation, HitNormal, out_CamLoc, Location, false, vect(12, 12, 12)) != none)
    {
        out_CamLoc = HitLocation;
    }

    return true;
}



function AddDefaultInventory()
{
    local GladiatorInventory MWInventoryManager;





    if (SwordArchetype != None)
    {
        MWInventoryManager = GladiatorInventory(self.InvManager);

        if (MWInventoryManager != None)
        {

            MWInventoryManager.CreateInventoryArchetype(SwordArchetype, false);}

    }
}


DefaultProperties
{

	InventoryManagerClass=class'GladiatorInventory'
    Components.Remove(Sprite)
	SwordArchetype=MeleeWeapon'GladiatorContent.Archetypes.MeleeWeaponSword'
    Begin Object Class=DynamicLightEnvironmentComponent Name=MyLightEnvironment
       bSynthesizeSHLight=true
       bIsCharacterLightEnvironment=true
       bUseBooleanEnvironmentShadowing=false
    End Object
    Components.Add(MyLightEnvironment)
    LightEnvironment=MyLightEnvironment

    End Object
    Mesh=MySkeletalMeshComponent
    Components.Add(MySkeletalMeshComponent)
}

And yes i want to use it in this class but whatever i try it's not wroking

What's the way?
or multiple ways?

[Marcio]

Try this (to call a function anyway):

GladiatorPawn(Pawn).YourFunction();

YourFunction() would be the name of a function in the GladiatorPawn class

[Neongho]

it doesen't work help please

[Graylord]

You need to elaborate more than just saying it doesn't work. "Doesn't work" could mean anything.

What's the problem? Do you get an error? What is the error?

[Neongho]

i do this GladiatorPawn(Pawn).AddDefaultInventory();

and i get this

'GladiatorPawn' Bad command or expression

[Graylord]

Trigger does not have a Pawn variable.

You need to find the player pawn manually, through something like a foreach, or spawn the trigger from somewhere you can access pawn to act as a connection.

[Neongho]

specify more please , the foreach looks to be the most erasonable way.
an example please¿ ?
i can provide information if you want

[daimaku]

if you are getting a touch on the trigger with your pawn you can use this code

vent Touch(Actor Other, PrimitiveComponent OtherComp, Vector HitLocation, Vector HitNormal)
{

    WorldInfo.Game.Broadcast(self, "you touch");

    super.Touch(Other, OtherComp, HitLocation, HitNormal);
   `log( "Hello, world!" );
    if (Pawn(Other) != none)
    {
        //Ideally, we should also check that the touching pawn is a player-controlled one.
        //this is the new line
        GladiatorPawn(Other).AddDefaultInventory();

	PlayerController(Pawn(Other).Controller).myHUD.AddPostRenderedActor(self);
	IsInInteractionRange = true;
    }
}

you can't use GladiatorPawn(Pawn) because you are receiving an actor variable called Other, try that and see if it work.

[Neongho]

if you are getting a touch on the trigger with your pawn you can use this code

    WorldInfo.Game.Broadcast(self, "you touch");

   `log( "Hello, world!" );
    if (Pawn(Other) != none)
    {
        //Ideally, we should also check that the touching pawn is a player-controlled one.
        //this is the new line
        GladiatorPawn(Other).AddDefaultInventory();

	PlayerController(Pawn(Other).Controller).myHUD.AddPostRenderedActor(self);
	IsInInteractionRange = true;
    }
}

It works ! thank you alot

How did you know , i always do this error , acces stuff from one class to another one , is there any tutorial teaching you this kind of stuff?
because this will still happend to me

[daimaku]

It works ! thank you alot

How did you know , i always do this error

is easy you just need to see what parameters are received on the function, check

Touch(Actor Other, PrimitiveComponent OtherComp, Vector HitLocation, Vector HitNormal)

there is no 'Pawn' variable

[Neongho]

One other question maybe it's not of this topic , well only a little

1If i wanted that object "TheUsable actor" , to be spawned in the map autoamtically , "any map" how would i do it without the editor

So it would be place it through urnealscript

2 If i wanted to destroy that object , make it dissapear , given an input how would i do it? "just the fucntion , or variable to change to make it dissapear"

3 How do i get the player position ( guess what i wanna do a dropping system : ))

[daimaku]

to spawn an object in runtime you need to use the spawn function, to destroy it you need to use YourObject.Destroy()

and the last one, depends on why you are handling things, most of the time if you are trying to drop something from the player controller, you can use Pawn.Location.

[Neongho]

i just need the palyer location one so that's 3

yes i got to spawn it and destroy it , but i need the palyer loc , and assign it to the spawn location wich i guess both are vectors

Another question jsut to get general information

is there a way to get a new key , some functionality ?
because if m not wrong you can0t drop weapons in UT game

so i'd like to create my own key , any tutorial out theere?

Pawn.Location.

im a use that , it gets ticked all the time right?

[daimaku]

if you are talking about to assign a key to do an specific function you can use bindkey to call an exec function from the player controller.

the pawn.location is ticked always.

if you want to see some good tutorials please check this site

udkc.info

is a good one

[Neongho]

Ok i have another problem in order to complete my dropping system , i have to call a function from the class " USABLE ACTOR " to the CLass " GladiatorController"

UsableActor Function
function spawnPickup()
{
WorldInfo.Game.Broadcast(self, "you spawned");
}


Player Controller exec Funct

exec function additembykey()

{
GladiatorPawn(Pawn).addanitem();
UsableActor.spawnPickup();
}

the first one works ,
but UsableActor.spawn , well i jsut get the typical error of bad command or missing expression


Can you place exec functions and keybind them on an actor class such ?

[jpvg]

If you want to start programming, you need to start using the UDN -> http://udn.epicgames.com/Three/ExecFunctions.html.

[Neongho]

Im more likely looking on how to acces Usableactor Functions from pawn or controller , and call them .

Also i created a function in my class UsableActor , but ican't acces gladiator pawn there , how is that?

Aren't we lucky that we got the UDN & also this page might be good!.

[Spoof]

Use UnCodeX to browse the class files and find what functions, variables and relationships exist.

[Neongho]

If i use references , the varaibles doesen't change
so it's useless also i can't call functions like the spawn function of the actor

and the exec functions doesen't work " in the case you sue them for keybinding" in a class wich is not cotnroller or pawn

Ah ok i did somethign like this Pickup = spawn(class'usableActor',,, Pawn.Location); using my reference usableActor PIckup
