Hi there,

I am trying to emit a signal to my Camera but it is not being received by it.

My scene looks like this in terms of hierarchy:

  • RootNode

    • CameraParentNode

      • Camera
    • NodeWithScript

Camera has a simple script attached, which has a signal and a function that is triggered when this signal is received (this is configured via Node window in editor):

extends Camera

signal rotate_camera(direction)

func onCamerarotatecamera(direction):
print("Rotating camera!")

NodeWithScripthas a script attached that emits under certain conditions:

emitsignal('rotatecamera', Vector2(-sign(direction.x), 0.0))
print("Emmited horizontal swipe")

In runtime, I see "Emmited horizontal swipe" printed but not "Rotating camera!".
What could be the reason for the emmited signal to not be received by the camera script?

Signal should be defined in script that emit it. So your NodeWithScript script should have next lines:

signal rotate_camera(direction)
emit_signal('rotate_camera', Vector2(-sign(direction.x), 0.0))
print("Emmited horizontal swipe")

And node that want to receive signal should connect to it. Your Camera should have next lines:

func _ready():
    # connect node to signal
    get_node("/root/NodeWithScript").connect("rotate_camera", self, "on_Camera_rotate_camera")

func on_Camera_rotate_camera(direction):
    print("Rotating camera!")
