Hi. 
I’ve made a class for storing data in my project derived from UDataAsset but I have some problems with it. Firstly, I can’t edit some of the properties in the editor, when the variable type is uint16, int8 etc.
This works, and allow me to change property inside the editor:
UPROPERTY(EditAnywhere, Category = "Main", meta = (ToolTip = "Part point value"))
int32 PointValue;
But this is not working (Edit box is greyed and disabled):
UPROPERTY(EditAnywhere, Category = "Main", meta = (ToolTip = "Part point value"))
uint16 PointValue;
Should it work that way?
Also, I’m not able to compile the code when my variable names starts with lowercase letters.
This compiles:
int32 PointValue;
And this does not:
int32 pointValue;
Is it a bug or it just has to begin with uppercase letters?
Thanks in advance.
My whole code:
