Thanks for tackling this seemingly obscure but actually important topic. Unity's Animator doesn't have excellent UX, so it's nice when folks help unbox these topics well.

I searched for Unity animation controller interruption source because I needed to get an animation to interrupt and found your video. Nicely explained. I understand it now. And it will help me interrupt some of my animations. I'll check out your videos too.

This was a huge help man! Was trying to get a double jump animation to be more responsive, instead of having to wait for the first jump animation to finish and THEN do the double jump animation when players rapidly hit the double jump. Just setting the Interruption Source to Next State fixed this issue completely!

[Betruet]

Its crazy I just solved this in my project last night but your explanation was really nice to have. I also use animation events so I was getting really wacky behavior. Thanks!

[CapitánPotterius]

Thank you very much! You helped me fix my problem in a minute! XD

[ronigleydsonvilasnovas]

excellent video. I confess that when it comes to using the animator I'm not completely noob, but there are always new things to be learned, like the ones in this video.

[ryanaflalo]

Awesome video! Helped a ton! Just earned a sub.

[durvids]

Great stuff as always! Thank you for this video, super useful!

[TerminalJack]

Here's a little advice if you play around with this: Put the following line of code in a script. This will slow time way down so that you will have plenty of time to set the triggers during the transitions.

Time.timeScale = 0.025f;

Awesome video. Was looking all over for interruption source related info. You are really helping out the new devs my friend.

My animations get still interrupted ... by the stupid <Any State> object. It seems the <Any State> state completly ignores all the settings you just talked about. And the blog post you mentioned does not even cover the <Any State>. So - how to prevent the <Any State> from interrupting my animations just because an outbound transition condition is true on it ?

[germiyanbey]

Beneficial video, but second part (Next state) was very confusing for me and difficult to understand by words alone. So you could teach them (Next, Current & Next and Next & Current) with a demonstration too. Apart from these, you talk really fast (as this is a video for learning purposes, speed should be slower to understand better). But thank you very much for enlightening us on a subject which information is little.

Where can I find infos about Referenced Animator Controller in another Animator Controller?

[Indiechicha]

Let if mouse1 settrigger(punch). & Mouse2 settrigger (kick). If player's punch animation is not finished I want kick trigger to be false while mouse2 is pressed, how can i achieve that.

[SnakeEngine]

Thanks. Anyone an idea if that animation stuff is easier to handle in Unreal Engine?

[oredi]

Those states, affect only that list? I usually don't use it, but it seems those NEED the list to work. Is that the case? Ty for the video btw. <3

[fabianobersovszky]

Isn’t the channel’s name a bit confusing?

[bobjames]

I appreciate the effort here but you made confusing subject even more confusing. Try slow things down a little.

[ryanaflalo]

I have one question, I made a shooting animation for my game that I am developing and sometimes the animation is sped up and at other times, the animation is normal. It should play at a constant speed. Do you know why this occurs! Thanks!

[SaadAlm]

thanks for this explanation, i have a similar issue, but I haven't found a solution yet I have a blend tree and a state. When I press the left click, it triggers the state using a crossfade function. I can interrupt the state with another state, but if it's a blend tree, it doesn't interrupt. Do you have any solutions or tips for this problem? + do you have a discord server
