Mecanim get current Layer
Hi, maybe i just have the wrong approach, but i'm looking for a way to get the current layer in Mecanim.
I dont want to check on all clips contained in the layer, as in AnimatorStateInfo.nameHash //"LayerName.ClipName" (Animator.stringToHash("OnlyLayerName") doesnt trigger)
I have all characters emotes in a layer (set to override) and triggered by an int.
Now i want to check if it's currently inside the emote layer to reset the emote-int to 0
(and i do not want to check if each of the emotes is currently playing, as this seems very inefficient (around 15 emotes) )
In a general sense, there's no such thing as a "current layer." Every layer is active with a weight that determines its influence on the final animation. Of course, override also influences the final animation. As an optimization, Mecanim doesn't evaluate layers with a weight of 0.
If you only increase your emote layer above 0 when you're playing an emote, then you can call GetLayerWeight().
If your emote layer's weight is always 1, then you probably have a null state in the layer. Just check what state you're in, using GetCurrentAnimatorStateInfo(). This is basically what the example scripts do in Update().
You could also use a coroutine that sets emote-int back to 0 after, say, 0.1 seconds. Start the coroutine in the same code block where you set the emote-int.
Hey, thank you. Thats a good idea. Checking for 'not nullstate' is indeed a working solution.
I created this extension to get the dominant layer.
using UnityEngine;
public static class Extensions {
public static int GetDominantLayer(this Animator Animator) {
int dominant_index = 0;
float dominant_weight = 0f;
float weight = 0f;
for (int index = 0; index < Animator.layerCount; index++) {
weight = Animator.GetLayerWeight(index);
if (weight > dominant_weight) {
dominant_weight = weight;
dominant_index = index;
}
}
return dominant_index;
}
}
Basically it iterates through all layers in the animator and searches for the one with the highest weight.
