I will post this question as an answer, because i was searching trough out the Answer Hub and Redit and i couldn’t find the correct answer, How to call a function by name using BP, even with casting on different actors, UMG etc… there were like how to create this using C++ only ! but NO ! you can do it entirely using BP.
Call function : Set Timer By Function Name
and don’t forget to at least put (0.0000…1) at the end of “Time Float” idk why but i was trying over 1000 times and when i put Time above 0 it worked !
Hope this will help someone ! Cheers…
