unreal engine delay c++
To add a delay in Unreal Engine using C++, you can use the FTimerHandle
and FTimerDelegate
classes. Here are the steps to follow:
Create a new function in your class where you want the delay to occur. For example, let's call it
DelayedFunction
.Inside the
DelayedFunction
, define aFTimerHandle
variable to store the timer handle. For example:FTimerHandle DelayedHandle;
Create a delegate function that will be called after the specified delay. This delegate function will be responsible for executing the desired code. For example:
void OnDelayedFunction() { // Code to execute after the delay }
In the
DelayedFunction
, set the timer to call the delegate function after the desired delay. For example, to delay the execution by 2 seconds:GetWorldTimerManager().SetTimer(DelayedHandle, this, &YourClassName::OnDelayedFunction, 2.0f, false);
Here, this
refers to the current object, &YourClassName::OnDelayedFunction
is the address of the delegate function, 2.0f
is the delay in seconds, and false
indicates that the timer should not repeat.
- To cancel the timer before it fires, you can call the
ClearTimer
function with the timer handle. For example:GetWorldTimerManager().ClearTimer(DelayedHandle);
That's it! Now, when you call the DelayedFunction
, it will delay the execution of the code inside the delegate function by the specified amount of time. Remember to replace YourClassName
with the actual name of your class.
