I haven’t seen any option for Character filter on inputs on UMG which to my idea will be a very nice option.
Example on the option panel in UMG designer it would be nice to have a feature where you can set [a-z] / [0-9] / [a-z-0-9] / [A-Z] [a-z-A-Z] / [a-z]+$
It’s very common in a lot of programming languages to use this approach.
[a-z] = lower letters a till z are allowed
[A-Z] = capital letters a till z are allowed
[a-z-A-Z] = capital and lower letters a till z are allowed
[0-9] = numbers 0 till 9 are allowed
[0-9]+$ = numbers 0 till 9 and special character $ is allowed.
i’m not sure if there is a way of character filtering in blueprint but it might be a nice feature.
if you would like a input where you can only input a email address you could set the filter to [a-z-A-z-0-9]+@+. this will be a correct email filter : email@example.com (correct) - firstname.lastname@example.org (this woulden’t work because the filter won’t allow you to input a $ character and will just return a keyboard input false.
Please let me know if there is already something like this. i might have missed it.
