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

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():
    curPos = offset

func _process(delta):
    if isShake:

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
        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:
