It gives me : You cannot use UObject method delegates with raw pointers. on the second line.
What does that means ? Why can’t I do this ?
Thanks !
edit : This seems to occur because I try to set a timer from a non-UE class (it’s not an actor, not a blueprint, not a controller…), so how can I manipulate a “big global” timer from anywhere in the game like I’m trying to do ?
I think what is happening here is that the function GetTimerManager() actually returns a reference not a pointer (denoted by the ‘&’ symbol). To call any function from the FTimerManager object which is returned from GetTimerManager() you need to use a ‘.’ indead of a ‘->’.
e.g.
UWorld* World = whatever;
World->GetTimerManager().Whatever();
When you have issues like these in the future be sure to take a look at the documentation at Unreal Engine 5.1 Documentation | Unreal Engine 5.1 Documentation to see what return types are given with functions you are trying to call. This documentation has help me heaps when i get issues like these.
And you should use GetWorldtimerManager() as long as you are in any Actor extending class.
Additionally here is a code sample to get you started with Timer in UE4, Enjoy!
void AYourClass::SomeFunction()
{
GetWorldTimerManager().SetTimer(this,
&AYourClass::VictoryCheckAllThreadsDone, 1, false); //true for looping
}
void AYourClass::VictoryCheckAllThreadsDone()
{
//do stuff 1 second after the above function is called
}
Thanks for the answer. I have figured out what the problem is ; actually, I am trying to to create a timer from a class which extends nothing (not a BP, not an Actor…) and it appears that UE doesn’t like it. How can I create a “global” timer which is not depending on anything ? The goal is to create a thread working everywhere in the game (so as a static or global variable) ?
My knowledge is limited as i’m still new to Unreal as well, but from what i see is you cant create a global timer which isn’t dependent on anything. Best guess is to use the World->GetTimerManager() (which is instantiated on game start) to get the FTimerManager which has several SetTimer functions. Im kinda assuming here as a “manager” it is able to handle more than one timer at a time.
