Plugins in Unreal Engine 4

Adding features with ease

Dave has an awesome idea!

​

​

​

​

First try => BP Spaghetti ?

​

​

​

​

​

Sometimes code is simpler.

Now Dave wants to share it with the world!

Isn’t UE4 Open Source?

Then Git it done and let’s fork!

​

​

​

Wait… that’s huge!

​

​

Still need to compile the engine.

It won’t take long right?

Just ~40min

​

Now we’re done, right?

Nope…

The receiver needs to do the same process.

Tempted? ;)

The easy way: Plugins

• Plug and play!
• Expose functionality in C++ and Blueprint
• No engine compile required
• Enable/Disable with a toggle

​

Plugins are perfect for:

​

• New features
• External libraries
• Modifying engine features
• Extend editor functions

​

Example Plugins

• C++/BP Utility - Rama’s Victory Plugin (https://github.com/EverNewJoy/VictoryPlugin), 7z-ue4 (https://github.com/getnamo/ZipUtility-ue4)
• REST - VARest (https://github.com/ufna/VaRest)
• Input - Hydra (https://github.com/getnamo/hydra-ue4) , Leap, Kinect, PSMove (https://github.com/cboulay/psmove-ue4)
• Voxels - Cubiquity (https://github.com/volumesoffun/cubiquity-for-unreal-engine)
• Web - BLUI (https://github.com/AaronShea/BLUI), Unreal.js (https://github.com/ncsoft/Unreal.js)
• Many, many more!

​

How do you make a Plugin?

Plugin wizard!

​

How do you make a Plugin?

Change build settings if needed

Write code the same way as C++ Project

Compile and go!

Sweet, now let’s try!

• Let’s do something useful => a new feature
• Something that connects people
• Web technology based
• Real-time
• Make it easy to use
• Heard of….

Possible in less than 15min?
