Notes

stopping the game

1. create a function that handles all cleanup

   1. stop the timer

      • drag + CMD and drop Timer to create a reference
      • timer.stop

   2. set all node children process to false

      • Node function get_children will get them all3
      • iterate through them and set_process(false)

sound

import pane

• the scene panel on the upper left has an Import pane

  file:../../_share/media/img/albert/section03/S03_L16_E01.png

• this allows you to see details of items in the filesystem

changing details of imported items

1. make whatever changes you want, e.g. turn on "Loop"

2. then click the Reimport button

audio nodes

• Node->Node2D->AudioListener2D

  • overrides location sounds are heard from

• Node->Node2D->AudioStreamPlayer2D

  • plays positionnal sound in 2D space

• Node->AudioStreamPlayer

  • simple audio player

    • Playing: plays in the GAME EDITOR
    • Autoplay: plays as soon as it is loaded into the scene tree

create background music

• add new Audio node to the scene panel on the Game scene

  • use AudioStreamPlayer bc we don't care about position

• drag the audio file into Audio node->Inspector->AudioStreamPLayer->Stream

  file:../../_share/media/img/albert/section03/S03_L16_E05.png

  • you'll be able to see it when it's loaded

    file:../../_share/media/img/albert/section03/S03_L16_E06.png

• set Autoplay to "ON"

add effects

• use AudioStreamPlayer2D bc it has positioning
• CMD+drag the AudioStreamPlayer2D node to the game.gd script so we can play it
• call the effect when something happens (e.g. a gem hits the panel)

• find the position of where the even happens "area.position"

  audio_stream_player_2d.position = area.position
  audio_stream_player_2d.play()

add game over sound

• first make sure no other sound such as effects sounds are playing.

• call "stop()" on all such nodes

  audio_stream_player_2d.stop()

• load the game over sounds using "preload"

  • CMD+drag the sound file from the filesystem to the game.gd script
  • godot will automatically create a constant with the file name
  • godot will also set that file to "preload" with the appropriate file path

• set the stream property of audio_stream_player_2d to the preloaded sound and play it

  audio_stream_player_2d.stream = EXPLODE
  audio_stream_player_2d.play()

• put all this into a function and add it to the game​_​over function
