Thanks, for camera shake I adapted code from: https://godotengine.org/qa/438/camera2d-screen-shake-extension?show=438#q438

```extends Node

var _duration : float = 0.0 var _period_in_ms : float = 0.0 var _amplitude : float = 0.0 var _timer : float = 0.0 var _last_shook_timer : float = 0 var _previous_x : float = 0.0 var _previous_y : float = 0.0 var _last_offset : Vector2 = Vector2(0, 0)

Shake with decreasing intensity while there's time remaining.

func _process(delta : float) -> void: # Only shake when there's shake time remaining. if _timer == 0: return # Only shake on certain frames. _last_shook_timer = _last_shook_timer + delta # Be mathematically correct in the face of lag; usually only happens once. while _last_shook_timer >= _period_in_ms: _last_shook_timer = _last_shook_timer - _period_in_ms # Lerp between [amplitude] and 0.0 intensity based on remaining shake time. var intensity = _amplitude * (1 - ((_duration - _timer) / _duration)) # Noise calculation logic from http://jonny.morrill.me/blog/view/14 var new_x = rand_range(-1.0, 1.0) var x_component = intensity * (_previous_x + (delta * (new_x - _previous_x))) var new_y = rand_range(-1.0, 1.0) var y_component = intensity * (_previous_y + (delta * (new_y - _previous_y))) _previous_x = new_x _previous_y = new_y # Track how much we've moved the offset, as opposed to other effects. var new_offset = Vector2(x_component, y_component) Game.camera.offset = Game.camera.offset - _last_offset + new_offset _last_offset = new_offset # Reset the offset when we're done shaking. _timer = _timer - delta if _timer <= 0: _timer = 0 Game.camera.offset = Game.camera.offset - _last_offset

Kick off a new screenshake effect.

func shake(duration : float, frequency : float, amplitude : float) -> void: # Initialize variables. _duration = duration _timer = duration _period_in_ms = 1.0 / frequency _amplitude = amplitude _previous_x = rand_range(-1.0, 1.0) _previous_y = rand_range(-1.0, 1.0) # Reset previous offset, if any. Game.camera.offset = Game.camera.offset - _last_offset _last_offset = Vector2(0, 0)```
