Delay the bullet creation?

[Steven_Fotheringham]

Looking for some advice/suggestions - I want to add a delay in the code, in between playing the animation & instantiating the projectile:

    private void shootAction_OnShoot(object sender, ShootAction.OnShootEventArgs e)
    {
        animatorPlayer.SetCharacterState("Cast2"); //My code looks different, as I am using other assets

        //This is where I want to add the delay

        Transform bulletProjectileTransform = 
            Instantiate(bulletProjectilePrefab, shootPointTransform.position, Quaternion.identity);

I tried using an Invoke, but that doesn’t work when you have parameters (as we do). I’m not sure if I could use this as a Coroutine, as I am still very new to coroutines.

Any suggestions?

I would use a coroutine. They’re really not that complicated, and Unity suggest you use them anyway. From the documentation for Invoke

If you need to pass parameters to your method, consider using Coroutine instead. Coroutines also provide better performance.

I don’t know if you are using any of the parameters, so here’s a sample that passes them both. You can remove the ones you aren’t using

private void shootAction_OnShoot(object sender, ShootAction.OnShootEventArgs e)
{
    StartCoroutine(OnShootRoutine(sender, e));
}

private IEnumerator OnShootRoutine(object sender, ShootAction.OnShootEventArgs e)
{
    animatorPlayer.SetCharacterState("Cast2"); //My code looks different, as I am using other assets

    yield return new WaitForSeconds(2f); // <- Wait here for however long you want

    Transform bulletProjectileTransform = 
            Instantiate(bulletProjectilePrefab, shootPointTransform.position, Quaternion.identity);
    // rest of the code
}

This is pretty much how I would handle this as well.

@bixarrio

private void shootAction_OnShoot(object sender, ShootAction.OnShootEventArgs e)
{
    StartCoroutine(OnShootRoutine(sender, e));
}

private IEnumerator OnShootRoutine(object sender, ShootAction.OnShootEventArgs e)
{
    animatorPlayer.SetCharacterState("Cast2"); //My code looks different, as I am using other assets

    yield return new WaitForSeconds(2f); // <- Wait here for however long you want

    Transform bulletProjectileTransform = 
            Instantiate(bulletProjectilePrefab, shootPointTransform.position, Quaternion.identity);
    // rest of the code
}

This solution was absolutely perfect! Thank you so much!

For this kind of scenario is exactly why I created my simple FunctionTimer in my utilities Trigger an Action after some Time - Code Monkey
I can easily pass in an Action and trigger it after some time.

But yes that Coroutine would work just the same.
