how to excute some lines when a black screen is on?-CodePudding

I have a UI animation for a black screen that fades in (goes from transparent to black) and another that fades out (goes from black to transparent). I'm trying to play the fade-in animation (screen becomes black) and then execute some lines of code while the screen is still black and then play the fade-out screen.

I tried to achieve this using StartCoroutine(Text()); like so:

    transitionAnim.Play("fade_in");
    StartCoroutine(Text());
    character.SetActive(false);
    Damagedcharacter.SetActive(true);
    transitionAnim.Play("fadeout");

 IEnumerator Text()  //  <-  its a standalone method
    {
        yield return new WaitForSeconds(1f);
    }

I want these lines:

character.SetActive(false);
Damagedcharacter.SetActive(true);

to be executed during the black screen. but they are not. what happens is that they are executed first then the black screen fade in and out.

How can I make the black screen stays for a while and execute some lines during the black screen and then fade out?

CodePudding user response：

A Coroutine doesn't magically delay the code in the method it is started from.

Either move your lines to the end of the IEnumerator like

transitionAnim.Play("fade_in");
StartCoroutine(Text());


IEnumerator Text()
{
    yield return new WaitForSeconds(1f);

    character.SetActive(false);
    Damagedcharacter.SetActive(true);
    transitionAnim.Play("fadeout");
}

Though personally I wouldn't mix animation and coroutine. Rather use Animation Events and have a callback for when you are faded to black and from there do stuff and then trigger the fade back.
