How to properly detect the end time of an Animation which wait for the end of the previous one ?

Hello everyone,

I already tried to post a similar question, but I had no answer so far, and I’m quite sure it’s because it is a way too complex for what it is.

So I’ll try to make very simpler and clearer.

Project :
The main goal is to create a system where a NPC have some tasks, and each one of them have 1/ a location (the NPC will walk there then continue) 2/ a specific animation (launched after the destination is reached). I want to synchronize the animation and the action : launch a specific method once the animation is ended. And finally, I want the NPC to wait the end of the “Walking” animation before launching the animation of the task.

Problem :
I’m looking for a good design for this. I’ve been on it for a long time now, and I just can’t find something even though it seems like a very basic problem. I tried to lock the completion of the task with this chunck of code, but for some reasons it don’t fit perfectly with the end of an animation…

{
     float currentAnimLenght = _npcAnimator.GetCurrentAnimatorStateInfo(0).length;
     float normalizedTime = _npcAnimator.GetCurrentAnimatorStateInfo(0).normalizedTime;
     float normalizedTimeInCurrentLoop = normalizedTime - Mathf.Floor(normalizedTime);

     // Wait that the moving animation is ended
     yield return new WaitForSeconds(currentAnimLenght - normalizedTimeInCurrentLoop);

     // Set Trigger to launch the task animation, then wait until its end
     _npcAnimator.SetTrigger(name);
     yield return new WaitForSeconds(_animClipLenght[name]);

     // This boolean prevent the NPC to do next tasks until this one is done
     isAnimLaunched = false;
     yield return null;
 }

Can you please help me ?
Do you have any “classic” method, a previous topic or a YT video that shows a great way of doing this ?

Hi,

Have you looked into animation events? They basically allow you to call some code at a certain frame in the animation, so you could put an event at the animation frame where you want the action to happen. I put a link below for more info. Hope this helps!
