UE3 - UT3 Making more than 2 firemodes for a weapon

daniellleon · Oct 31, 2009

I am trying to make my own custom weapon, which will need up to 6 firemodes.

I been told that I have to modify the Inventory Manager class, and the PlayerController class to succefully implement the weapon with 6 firemodes.

The inventory manager will be needed to properly trigger the the Start Fire function.

The player controller will be needed so I can properly bind 4 additional keys to select the last 4 fire modes

The first two fire modes I am keeping them standard and using Fire, and Alt Fire

This is the code I have so far....

------------------------------------Pawn---------------------------------------

Code:

class premPawn extends UTPawn;
var bool bOwnGun;

function Reward()
{
	local premPawn G;
	local Inventory I;
	bOwnGun = true;
	G = premPawn(Instigator);
 I = spawn(class'Sword');			// makes the sword part of the inventory
	if (G != none)
	{
		I.GiveTo(G);				// assigns the weapon to pawn G
		I.AnnouncePickup(G);        // announces that pawn G has pick up the weapon
	}
}

DefaultProperties
{
	bOwnGun = false;
}

------------------------------------Weapon------------------------------------

Code:

class Sword extends UTWeap_ImpactHammer;

//local premInventory I;
//I = premInventory(Instigator.InvManager);
//local PlayerControlExt PC;
//PC = PlayerControlExt(Instigator.Controller);

function CustomFire0()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntA', -1);
}

function CustomFire1()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntB', -1);
}

function CustomFire2()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntC', -1);
}

function CustomFire3()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntD', -1);
}

function CustomFire4()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntE', -1);
}

function CustomFire5()
{
    local premPawn P;
    P = premPawn(owner);
    P.PlayEmote('TauntF', -1);
}

simulated function CustomFire()
{
    switch(CurrentFireMode)
    {
        case 0:
            CustomFire0();
            break;
        case 1:
            CustomFire1();
            break;
        case 2:
            CustomFire2();

            break;
        default:
            CustomFire0();
            break;
    }
    Super.CustomFire();
}

simulated function DrawSphere()             // this function is not currently in use
{                                           		// this function will be used to calculate the range damage of each attack
    local premPawn P;
	local premPawn SpecialPawn;
	ForEach DynamicActors(class 'premPawn', P)
	{
	   if (P.PlayerReplicationInfo != none)
	   {
		  SpecialPawn = P;
	   }
	}

    //SpecialPawn.DrawDebugSphere(RealImpact.HitLocation,20.0f,10,0,255,1);
}

simulated function Tick(float DeltaTime)

    //DrawSphere();
    Super.Tick(DeltaTime);

I think the way I have modify each class should work, but I do not know how to use my modify Inventory Manager and Player Controller class correctly.

var premInventory Invent;
Invent = premInventory(Instigator.InvManager);

var PlayerControlExt PC;
PC = PlayerControlExt(Instigator.Controller);

I am using those line to establish an instance of each class, but then I do not know how to use them or in which file to use them.

For example, I will need to use the "Invent" variable, and call what?

Invent."no clue what to type here"();

and where would I call such command.

Thank you very much for whatever help anybody can offer.

Dumb question, but why do you declare multiple exec functions for starting and stopping fire, with each of them taking a parameter for specifying a fire mode number? Isn't that fire mode number exactly what you want to pass to the weapon so it knows which fire mode to use?

daniellleon · Oct 31, 2009

As far as the player controller modifications

The only thing i am adding are these variables

var bool bStartFire0;
var bool bStartFire1;
var bool bStartFire2;
var bool bStartFire3;
var bool bStartFire4;
var bool bStartFire5;

seems useless on its own, but I will need these variables later on to tell the enemy AI, what type of attack the player is doing and be able to react to them correctly.

To further explain what I am doing. I am creating a melee combat system. The weapon will be a sword, and each fire mode will perform a different attack or defense.

the first 3 fire modes are attacks and the last 3 are defenses. Therefore I need some type of variable to keep track of what attack the player is doing so the the AI bot can know which defense to counter attack with.

By the way thank you for organizing the display of my code into different windows, and thank you for any help you can provide.

InventoryManager has the variable "PendingFire", which is a dynamic int array. There's one entry for every fire mode, value 0 means "not firing", other values mean "currently firing".

daniellleon · Nov 3, 2009

Finally manage to figure it out.

For anybody out there that tries to do something similar.

Dont pay attention to whatever I did with the Inventory Manager, and the Player Controller classes. None of it was necesary.

Inventory Manager does need to be modify a bit though, but the only modification is the following... extend the inventory manager class and in the default property section type:

PendingFire(0)=0
PendingFire(1)=0
PendingFire(2)=0
PendingFire(3)=0
PendingFire(4)=0
ect

depending how many firemodes your weapon will have

Then to use your own version of Inventory Manager, go to your Pawn class and on the default property section type:

InventoryManagerClass=class'YourInventoryManageryName'

Then the major coding change comes to your weapon class you are modifying

On your weapon class default properties type:

Code:

    ShotCost(2)=1
    ShotCost(3)=1
    ShotCost(4)=1
    ShotCost(5)=1
    MinReloadPct(2)=0.600000
    MinReloadPct(3)=0.600000
    MinReloadPct(4)=0.600000
    MinReloadPct(5)=0.600000

    WeaponFireSnd(2)=None
    WeaponFireSnd(3)=None
    WeaponFireSnd(4)=None
    WeaponFireSnd(5)=None

    ShouldFireOnRelease(2)=0
    ShouldFireOnRelease(3)=0
    ShouldFireOnRelease(4)=0

    InstantHitDamageTypes(3)=Class'Engine.DamageType'
    InstantHitDamageTypes(4)=Class'Engine.DamageType'

You will need one for every additional firemode you have

Last, but not least remember to modify your .ini files if you wish to assign a different key for each firemode you have create.

Input.ini key binds

Thanks daniellleon for posting your finds, I've found it really useful! One question though, by what name do you call the extra fire modes in the input ini file? The default fire modes are called by "StartFire" and "StartAltFire", do I have to define my own, because I've tried a variety of combinations and have come up with nothing so far! I appreciate whatever help anyone can offer, thank you.

ShadowsWar · Dec 26, 2009

good deal man, thanks for the help, I was thinking in doing something like that to XD, just didn't know how =P

And I think that another way of doing the different attacks maybe be by doing something like if the player shot and is moving forward then it would give a attack, if he is moving backwards then would give another(i thing ou do that by using ragdoll or something like that)

A different ideia would be combos, so if the player use Fire, then it make a +1 combo, so if he keeps using Fire and doing +1 combos after then he can use altFire and the altfire would see how many combos the player has and call a different attack based on the numbers of combo ^^
But again, just some ideas ^^

Also, I remember the....Unreal Forever Tournament(and the 2k4 version), they had a weapon that used the 2 firemodes, like, if you press Fire and press altFire, then you would do another firemode....just don't know how they coded that, but was a interesting stuff, and in my opinion it would be nice to put something like that in a melee would be nice.

hey this is great...
i also want to create a sword.. but i am so stuck.. i got the source code for impact hammer from a website. bt its not working. i think its because i dont have those Skeletal Meshes and all those stuff included in the code..

can u please tell me where to learn about the unreal classes or can u help me to understand and extend the UTWeapon by my self.. i am very new to UDK.
i dont know what some keywords mean(Instigater, Pawn, KillStatName...etc.)
please someone help me.....
