How to switch LED's current effect inside loop()

[StarterCraft]

If I try writing code without dynamic LED effect switching like it's written below, it works normally:

#include "jled.h"
// do the parentheses actually break the library import?

#define myLED 13
JLed led(myLED);
//JLed led = JLed(myLed).On() - this does work too, but I don't see the difference

void setup() {
    led.On();
}

void loop() {
    led.Update();
}

But if I want to switch the LED's effect at the runtime according to a condition, nothing happens, the LED just ignores the instructions:

#include "jled.h"

JLed led = JLed(13).On().DelayAfter(2000);
bool _st;

void setup() {}

void loop() {
  if (someCondition) _st = true; //for example, switching the effect using a button
  if (_st) led.Blink(360, 360);
  led.Update();
}

How do I get rid of this problem?

You need make sure only to call led.Blink(360,360)once. In your example, it will be called over and over again, resetting the effect again and again. In your code e.g. you could do:

bool _st = false;

void loop() {
  if (someCondition && !_st) { 
      _st = true; 
      led.Blink(360, 360).Forever();
  }
  led.Update();
}
