Thank you very much for your response.
Regarding the system where one Blueprint Actor enables the next action after interacting with another (e.g., “after doing ○○, you can now do △△”), does this mean that I need to pass variables or set up communication between them every time?
Also, is it necessary to use the Level Blueprint in such cases?
Or can everything — such as story progression flags or event triggers — be managed entirely within each individual Blueprint Actor?
As a reference, I’d like to ask:
If you were to create a series of events like this —
for example: after doing ○○, you can proceed to △△. Once that’s completed, you can talk to a certain NPC. After the conversation, a trap trigger box becomes active —
how would you recommend structuring this kind of task/flag-based story system in Unreal Engine?
