Hi everyone,
I’ve been working on a project using Unreal Engine’s Blueprint system, but I’m running into difficulties debugging complex logic flows. Sometimes, it’s hard to track which part of the Blueprint is causing unexpected behavior or bugs.
Could you please share your tips or recommended tools and techniques for effectively debugging Blueprints? Are there any best practices to organize Blueprint nodes for easier troubleshooting?
Thanks a lot for your advice!
Add logging (Print String) if the logic went the wrong way.
Literally what you want:
But if I’m not mistaken, it only works when a breakpoint is triggered, and does not show the situation in real time.
For real-time, you can enable debugging for a specific Blueprint instance:
Then your graph will display the execute calls of connections, and the values of variables (but be careful, sometimes you can see the cached value, and not the one that actually exists, Print String is a more reliable way to get variable value).
I encapsulate code chunks in functions, then use print strings in the functions as I step through.
