Hello Everyone !
I decided to make a topic for newbies (as i am) in Blueprint visual scripting.
I think it will be pretty informative for juniors as well as kind of practice for advanced guys out there 
So let me start
Here is a blueprint to spawn an class-actor when you hit a button.
Here you can see event Input for assigned button (right mouse click in my case) , after that it goes to spawn actor node with location of player.
Bomb class Blueprint is pretty simple , consisting of sphere shape and 3 nodes :
Delay of one second -> spawn blueprint class explosion (from example) -> destroy actor (self)
So we got king of bomb placed at the place of actor.
I will update this topic with more simple stuff.
For now i have next goals to tackle :
- make “Bomb” grow withing a second after that explode.
- make fire at the place of explosion to stay for 2 seconds.
For now idea to make “grow” is like that - Dropbox - Error , but for some reason it is not working and i am trying to investigate why , any help will be appreciated !
