How to make a clock system that works with Ultra Dynamic Sky

[mco_dev]

Hi there,

I recently bought “Ultra Dynamic Sky” by Everett Gunther… it really works great, however i wanted to add a clock to display the time of day on the screen when in game, using widgets however there is no good tutorials on youtube on how to create a clock, i’ve been searching but found nothing…and also if i could add a system-time functionality to UDS that also be great… could some one give me a blueprint of how to set the clock up and have it functioning?

I have attached some screenshots,
Any help is greatly appreciated!

I do something like this for my time system

In my game instance i set up variables for my time and date and whenever one of them change i broadcast the new value. I tick it in my game mode btw, so stuff like the main menu doesn’t tick it and change the time. And then on my clock widget on begin play or whatever it is, i set it up to listen to those event dispatchers and set the time it shows to whatever time it currently is, so it doesn’t have to change the time displayed every frame if i did it with tick. I do the same thing to the sky sphere, make it listen to whenever the anim time changes and update the sphere then. In the default sky sphere I would do some math and update the sun angle or something, but for your sky I think what you’d do is set the “Time of Day” variable to animTime * 100 and then update it.

.h

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FAnimTimeChanged, float, animTime);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FMilisecondsChanged, int32, miliseconds);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FSecondsChanged, int32, seconds);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FMinuteChanged, int32, minute);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FHourChanged, int32, hour);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FDayChanged, int32, day);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FSeasonChanged, class USeason*, season);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FYearChanged, int32, year);

i know this is code, but i dont understand any of it :(… could you perhaps show me in BPs?

Thanks,
