Notes

add a Label node

• add Label node to Root node of Game

  • child of CanvasItem and Control
  • NOT a Node2D

• appears in upper left corner of the 2D screen

  

set label text

• go Scene->Label node->Inspector->Label->text
• type in whatever you want, e.g. '0000' for score

make the size bigger

• Scene->Label node->Inspector->Control->Theme Override

  • set the font and font size

move the label

• Scene->Label node->Inspector->Control->Layout->Transform
• change the Position values

if using shadow and offsets

• you set the colors in Theme Overrides

• change shadow offset and outline size in

  • Inspector->Label->Theme Overrides->Constants

Displaying the score

create a var to hold the score

var _score: int

register when the paddle hits a gem

• currently this is a signal on the paddle node
• disconnect paddle from receiving the signal bc we only want game node to receive it

in the game scene

• Scene->Paddle->Node->Signals
• Area2D -> area_entered
• set the register to the Game node

create a reference the Label node

• purpose: modify what the Label displays from the script

using onready

1. type it in

@onready var score_label: Label = $Label

1. drag and drop

   • grab the node from the Scene panel
   • hold down CMD
   • drop it on the script

update the score and the label

• update the _score variable in receiving method

• set the text property in the label reference to the score

  func _on_paddle_area_entered(area: Area2D) -> void:
    _score +=1
      label.text = str(_score)

remove the gem from the scene if it hits the padde

• the area2D node passed into the receiver method is a reference to the gem node

• so you can use the queue_free method to remove it from the scene queue

  area.queue_free()
