You aren’t assigning anything to TestVariable and then you’re using it in the FindLastChar method. That’d not gonna work.
Hello everyone! I am making a plugin using the Blueprint Library plugin template. I added this to the code:
This is the .h file.
And this is the .cpp file:
When I compile the plugin, UE4 says "Error C4700: uninitialized local variable ‘Test Variable’ used. Did I do a mistake or is it an engine problem? Thank you in advance! 
I changed it to
char TestVariable = “a”;
It still gives errors.
“Cannot convert from ‘const char[2]’ to char” and “There is no context in which this conversion is possible”.
That’s because “a” is a string or char array. ‘a’ is a char.
Wow, I can’t believe I forgot this. Thank you!
