Hi guys
I am using following code to delay the execution of my code (i.e. blueprint-like Delay in C++):
As you can see, lambda does some operations with properties and methods in this object (which is scope-captured by “=”). Will this crash, if e.g. this (AActor in which this code is written) is destroyed after setting timer on the last line of this code, but before timer fires?
I have the same Issue in ue4.21.
I’ve managed to avoid crashes by explicitly making a TWeakObjectPtr of “this” and capturing that ptr in the lambda scope (by value). Inside lambda I check if that weakPtr.isValid() and have not faced any crashes so far.
Pls lemme know if that works for u.
TWeakObjectPtr is the save way to do this,
generally just using this in lambdas that are not immediately executed is a bad idea
