Can I get the name of the current state in my animator?

Unity Engine

Is there any way that I can get the name of the state that is currently active in the animation controller in an animator?

I’ve been looking all over for this, but I can’t find it. I can’t find a variable for it within StateMachineBehavior, I can’t find a function to return the current state name within Animator, and even if I use Animator.GetCurrentAnimatorStateInfo, the AnimatorStateInfo it returns doesn’t have a value for the name of the state.

I can issue a command to play a specific state, and I can check if the current state has a name that matches something I can send it, but I want to just get the actual state’s name.

animator.GetCurrentAnimatorClipInfo(0)[0].clip.name;

I think this is what you’re looking for, I tested it out and it returns the name of the current animation.

The animator internally only uses hashes of the names (as int), not the actual strings of the names. In the editor, you might be able to hack yourself around that somehow but in the builds, the original names simply don’t exist.

There’s Animator.StringToHash, which will turn a name into a hash. You can use that with Animator.GetCurrentAnimatorStateInfo and AnimatorStateInfo.shortNameHash to check if the current state is the one you’re looking for. That’s exactly what AnimatorStateInfo.IsName is doing.

If you need the names at runtime, you’ll have to build a reverse lookup table that maps hashes back to names. In the editor, you can poke at Animator with reflection to call the private APIs that tell you the names.

Answers are talking about getting the name in the AnimatorState but how could we get the name of the AnimatorState ?

I wasn’t talking about the animation clip name but the animator state name, “State B” in your screenshot.

Nothing has changed since, state names do not exist as strings in the build and you’ll have to somehow work around that.

I founded this issue for below：

//this are variables you get inside the StateMachineBehaviour
Animator _Animator, int _iLayer, AnimatorStateInfo stateInfo
UnityEditor.Animations.AnimatorController _AnimatorController = _Animator.runtimeAnimatorController as UnityEditor.Animations.AnimatorController;
        UnityEditor.Animations.AnimatorStateMachine _StateMachine = _AnimatorController.layers[_iLayer].stateMachine;// this is reference to Base Layer
//this is how you get the name of each state inside a for loop
_StateMachine.states[i].state.name
// you can use teh compare to see if name matches
stateInfo.IsName(_StateMachine.states[i].state.name);

lua script is:

function  findAnimation(object,animName)

    local animator = nil;
    animator = object:GetComponent("Animator");
    local states = animator.runtimeAnimatorController.layers[0].stateMachine.states;
    for i = 0, states.Length - 1 do
        local state = states[i];
        print("state:"..state.state.name);
        if state.state.name == animName then
            return true;
        end
    end
    --[0].state.name;
    --print("adsfafds:" ..clips);
end

Layer was used default 0

Strangely, there is no built-in way. You have to create a Dictionary<int, string> and populate it with Animator.StringToHash(“Some State Name”), “Some State Name” for every state name in your animation controller. Then you can easily look up the state name from the dictionary by getting the state hash for the current state.

private static Dictionary<int, string> animStateHashToName = new Dictionary<int, string>();
// Populate your dictionary data.

// Then later look it up when you need it.
animStateHashToName[animController.GetCurrentAnimatorStateInfo(0).shortNameHash]
