Previously I wrote about delegates in UE4. Today I want to elaborate on this topic and tell you how to bind to delegates. We’ll mostly focus on C++ side but it’s not going to be very difficult so bear with me.
Binding a function to a delegate is basically adding a listener to an event dispatcher. Simple delegates allow adding only one listener, multicast – many. There is also a distinction between static and dynamic delegates. I will start with static.
If you have been developing in UE4 for some time you have probably stumbled into delegates.
What is a delegate? Delegates in two words are a UE4 implementation of the famous Observer template pattern. It allows code clients (or observers) to subscribe to some events. A dispatcher does not even know that something is listening to it. It just broadcasts events. This is a very powerful pattern – it makes your code less coupled.
I continue the series of tutorials dedicated to UE4 Slate UI Framework. In the previous post, I talked about a basic slate widget example. Now I want to show you how UE4 Slate widget reflector works (official documentation is here). It is a very useful and helpful tool that you are going to use a lot if you work with Slate.
Let’s say you want to see how an item in the World Outliner is implemented. Without the widget reflector, you are going to waste a ton of time searching for the exact location within the CPP code. But with the reflector, it is a matter of a minute.
I am starting a series of posts dedicated to UE4 Slate UI Framework. There will be tutorials, examples and quick how-tos. Everything to cover a lack of documentation on the topic from Epics. I’ll start with a simple example of a basic UE4 Slate widget where you select a value from a dropdown, enter a text and press an action button.
To start, create a C++ project. Create a subclass of UWidget: UGreetingsWidget. This will be a wrapper for our Slate widget:
Choosing a VCS (Version Control System) for game development is not as easy as in regular development. Where a choice is a no-brainer these days.
Gamedev is different in that regard because:
