Ive got another question. I have found a blueprint that works within my scene where I press the 1 key on the keyboard and the wind increases. What I want to do now is make it so that when I press 1 it increases slowly, not instantly. And also make it I can return it back to its previous state / turn it off. Also if it is possible I would prefer not to press 1 on the keyboard and have it go off after a certain amount of time.
Here is what the blueprint looks like at the moment.
Try applying the knowledge you just learnt about Timelines to solve the problem of increasing opacity in your clouds. The process will be very similar.
Spoon feeding you the answers will not make you a very good problem solver in the future. Try to figure out things for yourself first and when you are really stuck then come for help.
You need a reference to BP_Skydome, right now you are setting it (to nothing), so select it in the map, then open the level blueprint and right click, you should see an option to create reference to selected actor.
edit: Actually you’ve already done that when you are calling updateWeather, so set Cloud Opacity in the same way, drag off from the reference
