Go to the AgoraGameInstance_BP blueprint (double-click). The GameInstance is initialized before other classes so you create Agora here. Name the new GameInstance AgoraGameInstance_BP: In the All Classes section, type вЂњGame InstanceвЂќ and select the Game Instance class: Right-click the content and select Blueprint Class: Go to the Content project and create the new Blueprints directory. Find the Project > Other category and make sure that AgoraPlugin is enabled. Restart Unreal Engine (if it is running).PrivateDependencyModuleNames.AddRange(new string ). Add plugin dependency into the: /Source//.Build.cs file, Private Dependencies section.Your project should look like /Plugins/AgoraPlugin.

Download the plugin hereВ if you havenвЂ™t already.

Unreal Engine causes a compile error if the line is left commented out.

Uncomment the PrivateDependencyModuleNames line in the /Source//.Build.cs file.

On the New Project panel, choose C++ as the project type, enter the project name, choose the project location, and click Create Project.

Open the Unreal Engine Editor and click New project.

This is found within the Details tab by first clicking the Class Settings button.In this demo, IвЂ™ll walk you through each step needed to create a video calling app using Unreal Engine with the Agora SDK plugin!ДЇor this example, IвЂ™ll use Unreal Engine 4.25 and the current Agora SDK. You can use the Replicates checkbox for any Interfaces containing functions that need to replicate across the server. You can change where the input and output parameters appear on the node using theДЇound in the Details tab when the parameter properties are expanded. Input parameters can be given a default value using the small text field immediately under of the parameter name field, though you must expand the property entry in the Details tab to see it. On any input or output parameter, you can click the Note how the graph automatically updates to show them. In the same manner, outputs can also be added.

You may also expand the input using theД«utton next to the name, and thereby set a Default Value. In the Details tab, scroll to the Inputs category and click the

Since an interface function has no implementation, all you can do as a designer is designate a series of typed inputs and outputs. Note that the function has neither inputs nor outputs. The new Graph area will appear with the new function. In the My Blueprint pane, enter a name for the new function. In the My Blueprint tab create a new function, by clicking on the Add Button These can be used to send data through the interface, or can be overridden within any Blueprint that implements that Interface. They exist simply as a definition of inputs and outputs. Interface functions have no implementation. If you have just created your Interface, you will see that the Editor has created a new blank Function for you named NewFunction_0 and it will be highlighted for you to rename it.ДЇunctions are the primary component of an Interface.

When you first open up a new Interface, the editor looks like this: Since you cannot create your own variables, graphs, or components, the process of Interface editing differs greatly from the process of editing standard Blueprint Classes. Once created, you need to edit the Interface's functions.Д«lueprint Interfaces are edited the Blueprint Editor.

Read about how to implementД«lueprint Interfaces on the Implementing Blueprint Interfaces page.Д«lueprint Interface creation within the Content Browser is as simple as right-clicking and choosing Blueprint Interface from the context menu, then naming your new Interface. By creating a Blueprint Interface thatД¬ontains an OnTakeWeaponFire function, and having both the car and the tree implement that Blueprint Interface, you can treat theД¬ar and the tree as the same type and simply call the OnTakeWeaponFire function when either of them is shot. Share one specific thing like they can both be shot by weapon fire and take damage. This means you can have completely different types of Objects, such as a car and a tree, that The use of Blueprint Interfaces allows for a common method of interacting with multiple disparate types of Objects that all share

Put simply, Blueprint Interfaces allow different Blueprints to share with and send data to one another.Д«lueprint Interfaces can be made by content creators through the editor in a similar fashion to other Blueprints, but theyД¬ome with certain limitations in that they cannot: This is essentially like theД¬oncept of an interface in general programming, which allows multiple different types of Objects to all share and be accessed Of the Interface can be given functionality in each of the Blueprints that added it. Any Blueprint that has the Interface added is guaranteed to have those functions. A Blueprint Interface is a collection of one or more functions - name only, no implementation - that can be added to
