4. Weapon Leveling System

In this step, you will create a gun game-style weapon-leveling system in Verse that uses an Item Granter device to give players a new weapon when they complete a combo.

Modify Your Island

1. Select the Island Settings device in the viewport or Outliner panel.

2. In the Details panel, set the following parameters:

   1. Set Infinite Reserve Ammo to True.

   2. Set Infinite Magazine Ammo to False. This change requires the player to reload, an essential aspect of many Fortnite weapons.

3. Select the Item Granter device in the viewport or Outliner panel.

4. In the Details panel, set the following parameters:

   1. Set On Grant Action to Clear Inventory.

   2. Set Grant to Current Item.

   3. Remove all elements from the Index List, then add the following five elements:

      1. Assault Rifle L1

      2. Lever Action Rifle L2

      3. Heavy Shotgun L3

      4. Six Shooter L4

      5. Hand Cannon L5

   4. Set Receiving Players to All.

   5. Set Grant on Cycle to True.

   6. Set Grant on Game Start to True.

   7. Remove the Enable and Grant Item function bindings.

5. Select the Score Manager device in the viewport or Outliner panel.

6. In the Details panel, set Display Score Update on HUD to True.

Write Verse Code

1. Open the shooting_range_manager_device.verse file.

2. Add the following variables to store a reference to the item granter device and track item level properties.

   Verse

       @editable
       ItemGranter:item_granter_device = item_granter_device{}
   
       @editable
       MaxWeaponLevel:int = 5
   
       var CurrentWeaponLevel:int = 1
   

   Copy full snippet(7 lines long)

3. Add the IncreaseWeaponLevel method to increase the weapon level variable and cycle to the next item.

   Verse

       # Increases the player's weapon level by one (up to the maximum value).
       IncreaseWeaponLevel():void=
           if:
               # If able to retrieve the first player and current weapon level isn't maxed, then...
               Player:player = GetPlayspace().GetPlayers()[0]
               CurrentWeaponLevel < MaxWeaponLevel
           then:
               # Increase weapon level and cycle to the next item.
               set CurrentWeaponLevel += 1
               ItemGranter.CycleToNextItem(Player)
   

   Copy full snippet(10 lines long)

4. Modify the OnComboTargetHit method to call IncreaseWeaponLevel.

   Verse

       # A hit callback that scores the ComboTarget and resets the combo.
       OnComboTargetHit():void=
           AdjustScore(ComboTargetScore)
   
   <# --- New Code Start --- #>
   
           IncreaseWeaponLevel()
   
   <# --- New Code End --- #>
   
   
   Expand code Copy full snippet(11 lines long)

5. Modify the AdjustScore method to multiply the score awarded by the weapon level.

   Verse

       # Adjusts the player's score by the provided value.
       AdjustScore(Value:int):void=
           # Start the timer if it hasn't started yet.
           if (not IsTimerStarted?):
               StartTimer()
          
   <# --- New Code Start --- #>
   
           # Sets the score award to the base value of the target multiplied by the current weapon level.
           ScoreManager.SetScoreAward(Value * CurrentWeaponLevel)
   
   Expand code Copy full snippet(36 lines long)

6. Save and build your Verse code.

Complete Code

using { /Fortnite.com/Devices }
using { /Verse.org/Random }
using { /Verse.org/Simulation }

# A device that manages shooting range gameplay.
shooting_range_manager_device := class(creative_device):

    @editable
    ScoreManager:score_manager_device = score_manager_device{}

Bring It Together

1. Select the shooting_range_manager_device in the viewport or Outliner panel.

2. In the Details panel, set ItemGranter to the Item Granter device.

3. Push your changes and playtest your island.

   1. Verify the weapon swaps after hitting a combo target, up to 5 times. At the 5th level, it stays the same.

   2. Verify the incoming score multiplies by the weapon level.
