Timeline Slider for cultural heritage modeling

Development Programming & Scripting

Hi Everybody

Sorry if my message is not in the right section.

I’m using Unreal Engine to reconstruct my city’s lost historical heritage from different eras.
I would like to create a tool or a blueprint and UI, like a slider or timeline to move from one era to another.
Is there a way to visualize the buildings over more than two dates using a timeline?
How can I create a blueprint or is there an automatic solution?

Regards
Jerome

Look into “unreal data layers”:

Then look into “widget slider”:

Then make it all pretty, and share results here :wink:

and best way to connect it aall together:

  • make umg widget with slider.
  • use “middle man” setup for communication: make middle man blueprint with event for eg in game mode.
  • make event in game mode: “EVENT_change_epoch”
  • make event dispatcher in game mode: “DISPATCHER_epoch_changed”
  • when you move slider call that event in game mode to change epoch
  • when it is called trigger (start) dispatcher epoch changed
  • both event and disspatcher should pass some variable that gives what is new epoch (best would be custom enum you declare)
  • create all buildings/chunks as "compacted level: (not sure this name). Compacted levels are basically blueprints with meshes as objects
  • place those bluidings/chunks on appropriate data layer (for epochs)
  • assign to dispatcher epoch changed, anything you need to react to that
  • create data layer changing event in game mode and also assign it to that dispatcher, this will change data layer and show/hide correct epoch chunks
  • add more things like lights sky, weather to that epoch changing (must be blueprint that assigns to dispatcher, just like game mode)

ps.
take a look into “prefabricator” plugin on FAB.COM, you may want to make buildings modular.
