Checking whether an option has been selected before

[CoyanCardenas]

In Dialogic 2 is there a way to quickly check if a choice has been selected previously and if so, disable it?

Currently I am having to set up a new global variable, set the variable to true if selected, then add a condition to the choice checking for the global variable. I can see my global variables getting filled up very quickly with 'throwaway' variables I just needed once. It would be much easier if I could just add a quick condition to the choice that disables the choice if it's been used once.

So you could do this :
- ask Clive about where we're going | [if has_been_selected == false] [else "hide"]

or even better distinguish between choices that are one time and choices that can be selected multiple times.
- Observe Clive Can be selected multiple times.
* Talk to Clive Can only be selected once then dissapears from the list of choices.

Hey @CoyanCardenas,
you can do this, however it requires a custom choice script. So if you haven't already, make your choice layer custom, create a custom choice button script and assign it to all the choice buttons in the layer.

Then you can use the _load_info() method to disable or hide (or do whatever) choices based on whether they have been visited (this requires the "Seen Events History" to be enabled in the dialogic settings):

extends DialogicNode_ChoiceButton


func _load_info(info:Dictionary) -> void:
	# Load text and visibility
	super(info)

	if info.get("visited_before", false):
		disabled = true

You could combine this with a custom extra data argument if you want this behaviour to differ on choices. For example like this:

extends DialogicNode_ChoiceButton


func _load_info(info:Dictionary) -> void:
	# Load text and visibility
	super(info)

	if info.get("only_once", false) and info.get("visited_before", false):
		disabled = true

Hope this helps!
