Participant::The boss can idle, summon, teleport and death, but for the summon and teleport animation, I don’t know why cannot play, and if you see the big comment things is that I previous use code but cannot work, so I use the bat as reference still cannot work, so can you help me to see where is the bug, thank you very much!

Moderator::I am unable to test your code, so you will have to test it on your end. I suggest commenting out certain states first and checking if your method of using a Bool for your animations is necessary.
I suggest you test by playing with your boss in action with the animator window open to see what’s actually happening in there. Perhaps bools are being called or set false too quiclkly.Perhaps you should simply use a Trigger parameter for your Summon and Teleport animation instead.
Then you should have exit time added to your transiitons from Summon > Idle, and also Any State > Teleport.
This will prevent instantly switching animations if the bools change while in the middle of an animation.
