DelaySystem and DelayCallback

DelaySystem is a class that allows async call of DelayCallback after the set amount of time has passed.

This is how to create a custom DelayCallback:

public class CustomCallback extends DelayCallback {
  // all the data that your Call function needs
  private let myInt: Int32;

  public func Call() {
    // custom function that i want to be called when the specified time has passed
    if this.myInt > 1 {
      FTLog("Input is bigger than 1");
    } else {
      FTLog("Input is smaller than 1");
    }
  }

  public static func Create(inputInt: Int32) -> ref<CustomCallback> {
    // use this way to create your Callback class in one line
    let self = new CustomCallback();

    self.myInt = inputInt;
    return self;
  }
}

and this is how you can use the DelaySystem to call the Callback function with a delay:

let delaySystem = GameInstance.GetDelaySystem(GetGameInstance());
let inputInt: Int32 = 2;
let delay: Float = 1.0;
let isAffectedByTimeDilation: Bool = false;

delaySystem.DelayCallback(CustomCallback.Create(inputInt), delay, isAffectedByTimeDilation);

You can take a look at Generic callbacks for more use cases.
