¿How do I make an attack animation with geckolib?

Use procedures to trigger the animation when you want it. To play it on attack, use AI condition for attack AI, and use start condition to play animation and return true for the value so AI actually runs.

Could you be a little more detailed with the explanation? Please

I mean specifically, what options should I choose within the procedures?

if you want to add animation for your mob do this ,use geckolib plugin and check this video https://www.youtube.com/watch?v=t0vw4K-caUQ&t=329s

What about animations made with blockbench?

Geckolib is for animations made with blockbench

I would like to know the same. I have an animation made and I have seen how to put animations in the Geckolib, but the problem is that I do not know what procedures to take so that every time the entity wants to attack, it uses the animation in its attack. I would appreciate it very much if you would help me. (Sorry if it's misspelled, my English is bad)

I made this exact procedure and it did not work, it's weird because if I put any other block in the "do" line, it works, but when I use the "play animation" block, it doesn't.

Also, the problem is not with the animation, I've tested it.
