Update: Godot's Visual Script will discontinue in Godot 4.0. Therefore, it's useless to continue using Visual Script in Godot now.

A lot of people who use Godot's Visual Script don't know how to call a function in another script.

Well, that's easy! You can just drag and drop a scene node, which is attached to the script, into the canvas as shown in the screen recording below:

A proper way to do it

Imagine if you have to call a function from another script a hundred times, but you need to change the structure of the scene node to which the script is attached later, then you'll definitely have a serious problem of having to edit those hundred nodes.

Therefore this is how you do to prevent it:

• Set a scene node to an object variable in the _ready function which will be called only once.

• Change call mode of the node to Instance.

• Put the object variable to the instance input port.

Now, if you need to change anything to this scene node that you want to call a function from, all you have to do is change just one node in the _ready function, instead of a hundred nodes in the canvas!

I hope this helps 👍
