Hello! Why logics function not correctly work in UE4? For example function NOT always return false, so as and other function
And second answer where in source cod i can find this function?
Do not trust the visual debugger to always return accurate results, many factors play into how it returns values.
As a rule of thumb you should always double check values with 2 different methods if you cant figure out why it isnt what you expected.
Use a PrintString node to verify what exactly is being returned instead of trusting the visual debugger.
