Hello guys, it`s me again. Sorry for always asking, however I am still learning Unreal Scripting and I like to get help from more experienced users here.
I am creating a weapon reload system, I have seen many tutorials on old epic games forums, and on youtube, however many of these tutorials are incomplete, so I had to fix many things (i got pieces from here and there). It`s almost working perfectly, I even changed the HUD in flash/scaleform to show the current bullets equiped on the gun and the total ammo the player has avaiable.
I will try to summarize what I did and what are my doubts.
Here is my weapon reload class:
######################################################
class WeaponReload extends UTWeapon;
//these variables are for handle the ammo quantity in the magazine
var int MaxMagAmmo, TransferAmmo;
var bool bIsReloading;
//reload function to play reload animation///////////////////////
exec function Reload() {
//this statement will prevent weapon reloading when ammo is full
if (AmmoTotal > 0 && !bIsReloading && AmmoCount < MaxAmmoCount) {
ForceEndFire();
bIsReloading = true;
PlayWeaponAnimation('WeaponReload', 1.9);
WeaponPlaySound(WeaponEquipSnd);
setTimer(1.9, false, 'AddAmmoToMag');
}
}
//reload function to play reload animation///////////////////////
//function Add Ammo To Magazine///////////////////
function AddAmmoToMag(){
//if AmmoTotal > 0//
if (AmmoTotal > 0) {
TransferAmmo = MaxMagAmmo - AmmoCount;
//if AmmoTotal >= TransferAmmo//
if (AmmoTotal >= TransferAmmo) {
//this will add the transfer ammo to the current ammo count
AmmoCount = AmmoCount + TransferAmmo;
//this will reduce from the ammo total the ammo which was transfered to the magazine
AmmoTotal = AmmoTotal - TransferAmmo;
}
//if ammototal < TransferAmmo
else{
AmmoCount = AmmoCount + AmmoTotal;
AmmoTotal = AmmoTotal - AmmoTotal;
}
//if AmmoTotal >= TransferAmmo//
bIsReloading = false;
ClearTimer();
}
//if AmmoTotal > 0//
}
//function Add Ammo To Magazine///////////////////
//function to check if player is allowed to shoot///////////////
simulated function StartFire(byte FireModeNum)
{
if (bIsReloading) {
return;
}
Super.StartFire(FireModeNum);
}
//function to check if player is allowed to shoot///////////////

Here are some changes I made in UTWeapon
I added these 2 custom variables to control the total ammo the player can carry (that will be transfered to gun magazine when reload)
//custom variable for weapon reload system
var int AmmoTotal;
var int MaxAmmoTotalCount;
Then I changed the function AddAmmo to add ammo for the variable ammototal, so the player wll manually transfer ammo for the ammocount of weapon. It means that collecting ammo will not add ammocount, instead, will add ammo total, so the player when reloading the gun will manually transfer from Ammototal to Ammocount (gun magazine, the current ammo which is equiped in the gun):
//add ammototal for reloading system//
function int AddAmmo( int Amount )
{
//custom reload add ammo count
AmmoTotal = Clamp(AmmoTotal + Amount,0,MaxAmmoTotalCount);
// check for infinite ammo
if (AmmoTotal <= 0 && (UTInventoryManager(InvManager) == None || UTInventoryManager(InvManager).bInfiniteAmmo))
{
AmmoTotal = MaxAmmoTotalCount;
}
//custom reload variable
return AmmoTotal;
}
//add ammototal for reloading system//
However when I have done this, the ammocount was not being reduced when the player shoots, so I changed the original AddAmmo function to this:
//original add ammo function
function int AddAmmoDefault( int Amount )
{
//default add ammo count
AmmoCount = Clamp(AmmoCount + Amount,0,MaxAmmoCount);
// check for infinite ammo
if (AmmoCount <= 0 && (UTInventoryManager(InvManager) == None || UTInventoryManager(InvManager).bInfiniteAmmo))
{
AmmoCount = MaxAmmoCount;
}
return AmmoCount;
}
//original add ammo function
And changed the function ConsumeAmmo to:
/**
* Consumes some of the ammo
*/
function ConsumeAmmo( byte FireModeNum )
{
// Subtract the Ammo
AddAmmoDefault(-ShotCost[FireModeNum]);
}
Then I also changed this function in the UTAmmoPickupFactory:
class UTAmmoPickupFactory extends UTItemPickupFactory
ClassGroup(Pickups,Ammo)
abstract;
/** The amount of ammo to give */
var int AmmoAmount;
//custom variable for reload system
var int AmmoTotalAmount;
/** The class of the weapon this ammo is for. */
var class<UTWeapon> TargetWeapon;
function SpawnCopyFor( Pawn Recipient )
{
if ( UTInventoryManager(Recipient.InvManager) != none )
{
//default add ammo to weapon
//UTInventoryManager(Recipient.InvManager).AddAmmoToWeapon(AmmoAmount, TargetWeapon);
//custom reload system add ammototal to weapon
UTInventoryManager(Recipient.InvManager).AddAmmoToWeapon(AmmoTotalAmount, TargetWeapon);
}
And last thing I modified the NeedsAmmo function from UTInventoryManager to don’t allow the player to collect the AmmoTotal more than the limit MaxAmmoTotalCount:
function bool NeedsAmmo(class<UTWeapon> TestWeapon)
{
local array<UTWeapon> WeaponList;
local int i;
// Check the list of weapons
GetWeaponList(WeaponList);
for (i=0;i<WeaponList.Length;i++)
{
if ( ClassIsChildOf(WeaponList*.Class, TestWeapon) ) // The Pawn has this weapon
{
//if ( WeaponList*.AmmoCount < WeaponList*.MaxAmmoCount )
//this will allow pickup ammo even if the ammocount is full
if ( WeaponList*.AmmoTotal < WeaponList*.MaxAmmoTotalCount )
return true;
else
return false;
}
}
I also created a new dynamic textfield in Flash for showing AmmoTotal variable and declared this variable in GFxMinimapHud
i = Weapon.GetAmmoCount();
if (i != LastAmmoCount)
{
LastAmmoCount = i;
AmmoCountTF.SetText(i);
//custom variable reload system
AmmoTotalCountTF.SetText(Weapon.AmmoTotal);
The only problem I am having now is that the Ammototal count only updates after I shoot or after I reload. It works fine. I collect ammo, and this ammo I collect does not increase the AmmoCount for the gun, rather it increases the Ammototal, then when I reload, it transfer the bullets from AmmoTotal to AmmoCount, just like it needs to be. Then it reduces from the Ammototal the ammount which was transfered for the gun clip (AmmoCount). However the AmmoTotal count only updates when I reload or shoot. It does not update when I Collect ammo (pickup ammo event).
Any tips?
Last but not least, how can I remove the function of UTGame which automatically changes to next gun when the ammo is empty and avoids the player to select a weapon which is empty of Ammo. I want the player to manually reload the weapon when ammo is zero, however, UDK auto changes for next weapon and avoid me selecting a gun with zero ammo.
Sorry for the long post.
