When i am compiling my projects i would like to know how many times i compiled my project. So i made that kind of functionality for one of our project and thought i’ll share it with you guys. :)
First of all you need a header file to track the game build changes. Here is a screenshot of my header file from our project. Its called GameVersion.h
Next i created a simple text file called GAME_BUILD.txt and it contained only the build number. Nothing else. This file was located in my Project Source/Project Name folder. (for example: D:\Unreal Projects\MyProject\Source\MyProjectFolder). Here is a screenshot of that file.
Now comes the real part. Go to your Project Folder/Source and open up MyProject.Target.cs file. Here in this screenshot you can see how i modified the main function. Modify it like that and make sure to point to your GameVersion.h and GAME_BUILD.txt files correctly.
Now every time you compile your project it will automatically increment your build number. To access this build number simply include GameVersion.h file and get GAME_BUILD_NUMBER. :)
Hope this tip was useful. :)
NOTE: The only downside to this method is it will always increment the build number even if your project fails to build.
Ever wondered how to rename your C++ classes that you already use in your project? For example, you have a C++ class called MyAwesomeClass and in your Content Browser you created a Blueprint extending from this class and added some important logic. Now if you rename the C++ parent class and compile, project might open but if you try to open that Blueprint you will see this error.
So in order to make this work, you need to tell Unreal that there is a new class for this and it should use that instead of the old one. In other words, you need to redirect from Old Class to New One and you do this in DefaultEngine.ini found in Your project/Config folder.
Open DefaultEngine.ini and under [/Script/Engine.Engine] section add the below line:
Thats it! Now you can start your project and open that Blueprint without issues. Hope you find this info useful. :)

So yesterday i made something like a map editor using Unreal Engine Blueprints and UMG.
This will be available to the UE4 community soon. :)
EDIT: You can download this from here: https://github.com/ryanjon2040/UE4-Map-Editor
Placeable spawn point
Posses and Eject player
2 Camera modes: RTS and Free Cam
Am pretty excited today because I modified Engine source to add a feature I wanted. Its called Blueprint Lock Node feature. Basically what it does is, prevents the user from accidentally deleting any nodes.
Toggles lock mode via context menu
And you will see a Notification saying node is locked…
…so you cant delete it
If you want to delete that node then simply click on Toggle Lock again
This feature works for multiple nodes too
The WordPress.com stats helper monkeys prepared a 2014 annual report for this blog.
Here’s an excerpt:
The Louvre Museum has 8.5 million visitors per year. This blog was viewed about 150,000 times in 2014. If it were an exhibit at the Louvre Museum, it would take about 6 days for that many people to see it.
Please let me know what you think. And for those who wonder…this is all voodoo Blueprint magic :P ;)
