Well Greased

Adds Animations to doors, trapdoors, fence gates and lever!

door animation

trapdoor animation

fence gate animation

lever animation

Works with redstone too!

Resource Pack Friendly!

For doors and trapdoors, everything is handled automatically.
For the lever and fence gates, there are two possibilities:

If the resource pack doesn't change the vanilla models (only the textures), then you don't need to do anything.
If the resource pack changes the vanilla models, you'll have to create a resource pack as follows (under assets/well_greased/models/block):

Lever

Basically, you'll have to separate the model to permit the animation of only the handle of the lever because the base is standing still. So one model for the base, one for the handle and one for the handle when the player has clicked on it.

The following shows an example for the vanilla lever:

        "east":  { "uv": [ 7, 6, 9, 16 ], "texture": "#lever" }
      }
    }
  ]
}

Fence Gate

Basically, you'll have to separate the model to permit the animation of the left part and the right part of the fence gate separately. So 4 models for the left part (one close, one close next to a wall, one open and one open next to a wall) and 4 for the right part (one close, one close next to a wall, one open and one open next to a wall).

The following shows an example for the vanilla oak fence gate (it's the same for other types of woods, replace just oak with your wood):
