I have a main scene with two children. One of the children is an instance of a board, which is made up of instances of a single space. The single space has a script. The other child of the main scene is another instanced scene. I want a signal to be sent by the space's script to the other instanced scene in the main scene.
When the mouse enters any one of the spaces on the board, I want the signal in the space script to be sent to the other child. How can I do this?
