Updating a Stat Interface

[coltschamps12]

Godot Version

Godot 4.2

I have a stat sheet interface in my game that I want to update every time I equip an item. When I equip a helmet the output does show that the stat is increased but it is not shown on the interface.

For example:
defense.text = str(playerstats[“Current_Defense”]) shows a defense of 17 when loading the game but doesn’t change after equipping a piece of armor that adds 4 defense.

I attempted to duplicate the player stat resource but that didn’t work. Any help would be appreciated. Thanks!

A more complete example of your code would probably help. In which function did you include defense.text = str(playerstats[“Current_Defense”])?

extends Control

const playerstats = preload(“res://Stats and Classes/Player_StatManager.tres”)

@onready var hp = $HP/Label
@onready var mp = $MP/Label

@onready var strength = $STRENGTH/Label
@onready var intelligence = $INTELLIGENCE/Label
@onready var agility = $AGILITY/Label

@onready var mp_regen = $“MP REGEN/Label”
@onready var stamina_regen = $“STAMINA REGEN/Label”
@onready var mp_cost_rate = $“MP COST RATE/Label”
@onready var skill_charge_rate = $“SKILL CHARGE RATE/Label”
@onready var recover_rate = $“RECOVERY RATE/Label”

Called when the node enters the scene tree for the first time.

func _ready():
hp.text = str(playerstats[“Current_Health”])
mp.text = str(playerstats[“Current_Mana”])
stamina.text = str(playerstats[“Current_Stamina”])
strength.text = str(playerstats[“Current_Strength”])
intelligence.text = str(playerstats[“Current_Intellect”])
agility.text = str(playerstats[“Current_Agility”])
defense.text = str(playerstats[“Current_Defense”])
magical_defense.text = str(playerstats[“Current_Magic_Defense”])
critical_strike_chance.text = str(playerstats[“Current_Critical_Rate”])
hp_regen.text = str(playerstats[“Current_HP_Regeneration_Rate”])
mp_regen.text = str(playerstats[“Current_MP_Regeneration_Rate”])
stamina_regen.text = str(playerstats[“Current_Stamina_Regeneration_Rate”])
mp_cost_rate.text = str(playerstats[“Current_Mana_Cost_Rate”])
skill_charge_rate.text = str(playerstats[“Current_Special_Charge_Rate”])

target_rate.text = str(playerstats[“Current_Target_Rate”])
experience_rate.text = str(playerstats[“Current_Experience_Boost_Rate”])

Called every frame. ‘delta’ is the elapsed time since the previous frame.

func _process(delta):
pass

You are assigning text to your labels in the _ready() function.
The _ready() function runs once when the scene is added to the tree.
So when you add the item to the players inventory the function has already run.

When a players stats have changed you have to update the text of the label.

Please use the code tag </> when posting code.

Right this code will only update the display on _ready() when the game starts. Each stat is being converted into a string and copied into the label’s text once and only at the start of the game. Let’s move it to a update_display function then call that when we update the playerstats, maybe using the changed signal resources have?

func _ready() -> void:
	update_display()
	playerstats.changed.connect(update_display)

func update_display() ->:
	hp.text = str(playerstats[“Current_Health”])
	mp.text = str(playerstats[“Current_Mana”])
	stamina.text = str(playerstats[“Current_Stamina”])
	strength.text = str(playerstats[“Current_Strength”])
	intelligence.text = str(playerstats[“Current_Intellect”])
	agility.text = str(playerstats[“Current_Agility”])
	defense.text = str(playerstats[“Current_Defense”])
	magical_defense.text = str(playerstats[“Current_Magic_Defense”])
	critical_strike_chance.text = str(playerstats[“Current_Critical_Rate”])
	hp_regen.text = str(playerstats[“Current_HP_Regeneration_Rate”])
	mp_regen.text = str(playerstats[“Current_MP_Regeneration_Rate”])
	stamina_regen.text = str(playerstats[“Current_Stamina_Regeneration_Rate”])
	mp_cost_rate.text = str(playerstats[“Current_Mana_Cost_Rate”])
	skill_charge_rate.text = str(playerstats[“Current_Special_Charge_Rate”])
	recover_rate.text = str(playerstats[“Current_Recovery_Rate”])
	item_recovery_rate.text = str(playerstats[“Current_Item_Recovery_Rate”])
	magic_reflection_rate.text = str(playerstats[“Current_Magic_Reflection”])
	physical_damage_negation_rate.text = str(playerstats[“Current_Physical_Damage_Negation_Rate”])
	magical_damage_negation_rate.text = str(playerstats[“Current_Magical_Damage_Negation_Rate”])
	target_rate.text = str(playerstats[“Current_Target_Rate”])
	experience_rate.text = str(playerstats[“Current_Experience_Boost_Rate”])

However the changed signal might not work for you. In this case let’s just call the update_display() function when equipping items.

[coltschamps12]

It’s still not working. Perhaps i’m calling the function incorrectly. Should I instantiate it? I used var CharacterStatsheet = load(“res://Equipment/character_statsheet.gd”) for the variable followed by CharacterStatsheet.update_display(). When I tried instantiating it before it returned all the values of the resources to null.

[gertkeno]

Could you post how you are updating the stats when equipping new items? Seems like you are loading the script and need to create a reasource or load a resource directly.

extends Node

const playerstats = preload(“res://Stats and Classes/Player_StatManager.tres”)

func apply_equipment_stats(item):
match item.serial_number:
“0001”:
playerstats.Current_Defense += 4
print(“Player defense:”, playerstats.Current_Defense)

func lower_equipment_stats(item):
match item.serial_number:
“0001”:
playerstats.Current_Defense -= 4
print(“Player Defense:”, playerstats.Current_Defense)

I think Im using the code formatting correctly. Thanks for the help so far!

[gertkeno]

on code formatting, close the </> button in the editor will make a block for you to paste code in it will look like this when you click the button on a new line

```
type or paste code here
```

Then you just paste your code with ctrl+v

Try calling update_display when updating equipment stats, I am not sure where you would get a reference to the interface, but here is an example

apply_equipment_stats(sword)
$StatsDisplay.update_display()

[coltschamps12]

Thanks for your help. I ended up getting rid of the resources for my stats and used variables for my stats on my character script and used signals to update the label.

Thanks again!
