How do you make the camera shake when an event happens like an explosion, etc

This code works very well:

Just set the offset property of the camera with small random values every frames, like this:
# Animate this to increase/decrease/fade the shaking
var shake_amount = 1.0
func _process(delta):
camera.set_offset(Vector2( \
rand_range(-1.0, 1.0) * shake_amount, \
rand_range(-1.0, 1.0) * shake_amount \
))
This will move the camera relatively to its center without interfering with its pivot, producing a shake effect.
Thank you all for the helpful answers

Hi there, with the code above, how is camera assigned?
If I try to use camera it fails. If I try and use Camera it fails also. Do I need to assign it somehow to the camera that you’ve used? Thank you.
EDIT: I’m assuming of course you can do this with the default camera in any scene? If not, then I guess I will need to create one, place it in the hierarchy, then manipulate that? I’ll do that to test, but I thought I’d be able to manipulate the default scenes camera rather than creating one.

camera is a variable in which you should have put a reference to whatever camera you want, before _process gets called. The way you do that depends on your game. It can be the result of something like get_node("Camera") for example. Because a game can have multiple cameras there is no default variable for this. There is a default “camera”, but it’s not a Camera node (see Viewport documentation).

Thank you. Yes I see that now. You have to create a camera to use it it seems, you can’t just use the one that is part of the viewport (“default” camera). I created a camera2d and life was better.

extends Camera2D
export var shake_power = 4
export var shake_time = 0.4
var isShake = false
var curPos
var elapsedtime = 0
func _ready():
randomize()
curPos = offset
func _process(delta):
if isShake:
shake(delta)
func _input(event):
if Input.is_mouse_button_pressed(BUTTON_LEFT) and not isShake:
elapsedtime = 0
isShake = true
func shake(delta):
if elapsedtime<shake_time:
offset = Vector2(randf(), randf()) * shake_power
elapsedtime += delta
else:
isShake = false
elapsedtime = 0
offset = curPos
Wow! This code actually works like a charm, this helped me a lot in my game, so I just wanted to say thanks!

I just made a quick, clear, and simple tutorial on how to do this:
