Unreal Engine Interaction - Event Dispatchers tutorial 

Thanks a lot! I was trying to make focused on people how are not complete beginners, but also not experts yets. Something you can follow and fill in the gaps on with stuff that you might know is possible but aren't 100% sure on how to do. I also wish this was recommended more :p

Thanks! I think it comes from my background not being in science. I learned programming like a spoken language rather than math equations. I like stuff like this If "the_door_is_open" then "walk_through()

Thanks! I really appreciate it Any other subjects you'd like to see like this?

Hah! thats a really good idea. what I really love about game development is that you can actually create fun and engaging gameplay only using simple methods. You don't need to know all of unreal engine to make a game. Just learn a few things, look out for opportunities to make something fun and build the game Would love to see it if you were to build this :D

Thanks! I really appreciate it. Its comments like this that really motivate me to make videos :D

Awesome! let me know how it goes and if there is something I can add in future videos :D

Thank you! :D

Thanks alot! Glad you liked it 🙂

Yeah definitely! One way would be to make it so that on BeginPlay each one of the spheres register itself to a global object. For example, create an array on the gamemode called "ActorsToMonitor" or something like that. That way you don't have to do GetAllActorsOfClass() but can rather do GetGamemode->GetActorsToMonitor and loop through that to bind This is a pattern called "publish-subscribe" in computer science and can be tricky to solve well in some cases. The problem to solve is you need to know which actors are publishing (or broadcasting events) and which actors should subscribe (or bind to the events). But if the pub-sub relation ship never changes. that is on BeginPlay the actor should always just listen to a set number of actors then GetAllActorsOfClass is fine If you want to do this dynamic, where new actors are spawned into the level and you want the listener to bind to the new actors then having them register to a global object like I mentioned could work. The real tricky part starts when you need to also remove the bindings based on some criteria, like if an actor has moved too far away from the listener then remove the binding and if it gets close enough add it :)

Thanks a lot! The Bind Event node is made in a way that it accept an array as an input. So the event will bind to either a single entry or every entry in an array. Behind the scenes its probably doing a "for each loop" when it does the binding, but for us in blueprint land we can use it like this :D

Thanks for the feedback! do you have an example of a good resource to tech event dispatcher?

@@gisli my advice is to start the default third person scene (everybody will have the same starting position when doing the tutorial). Then keep the dispatcher as simple as possible, something like when you run into a cube you get an event. Simply is the way to go.
