Change Mecanin animation Layer weight

grossimatte

Hello Chris,
I could not find a way (through action lists) to change the weight of an Animator layer.

Say i want the player to pick up a box. When this happen, rather than triggering a custom animation, i want instead to set the weight of the masked layer containing the additive pose to 1.

My player is 3D and is using Unity Mecanim's animation system.

Thanks!

Here's a custom Action, Player: Set layer weight, that you can plug into your Actions Manager.

Name the file ActionPlayerWeight.cs, and place in a new Assets folder.

using UnityEngine;
#if UNITY_EDITOR
using UnityEditor;
#endif

namespace AC
{

    [System.Serializable]
    public class ActionPlayerWeight : Action
    {

        public int layerIndex;
        public float newWeight;

        public override ActionCategory Category { get { return ActionCategory.Player; }}
        public override string Title { get { return "Set layer weight"; }}

        public override float Run ()
        {
            KickStarter.player.GetAnimator ().SetLayerWeight (layerIndex, newWeight);
            return 0f;
        }

        #if UNITY_EDITOR

        public override void ShowGUI ()
        {
            layerIndex = EditorGUILayout.IntField ("Layer index:", layerIndex);
            newWeight = EditorGUILayout.FloatField ("New weight:", newWeight);
        }

        #endif

    }

}

Hey there! I found this script and could use it for my project. Thing is, the script gives me the error 'ActionPlayerWeight.Run() not all code paths return a value. Sorry if this is a minor issue. Just started to get into cs aswell. Cheers!

Welcome to the community, @Voxxy.

It's my fault - I made a typo in the code. I've corrected the post now.

Thanks alot for the lightning reply, @ChrisIceBox! And thanks for your awesome adventure creator. Will this script work in sprites unity complex aswell?

ChrisIceBox
