I am using the BlendTree in my AnimationTree, and I put a BlendSpace2D to have my character walk, I find that the animation between walking directions is not blended, but instead a lot more snappy, which looks weird considering that it's the direction of a walk cycle. What are my options for making the animation have a more smooth transition between Front Left and Front walking animations?
I am also having this issue. I know in theory what the solution is, I am still putting together a solution.
In theory, it is because you are assigning hard values that dont transition, so -1s, 0s and 1s would be an example. But you have to have it slide between -1 and 1 with your animation to blend properly. I am working on a quick fix now, and I will post it here when I have it fleshed out. :)
Great! :), I know that if you don't use the animation tree, but just the player, there is an option for you to set the time it takes to switch to each animation, which makes the changing movement really nice, ofc without the benefits of the animation tree. Unfortunately, I have not been able to find such an option for the 2D blend space :'(. But I'm stoked to hear about what your solution is though :)
I wonder if you couldn't use the call method track in animation player to be able to set up a key/event for a method to change the necessary value...
Okay I have this figured out. So firstly you are looking to interpolate between these states. I have done some code in relation to my own character controller with a BlendSpace2D and I will post the relevant code below
So I utilize these variables and initialize the walk_transition (which is the current value) in the _ready function, then through the controller's directional function I grab the "target value" (which is the movement_state, or the value being interpolated to), then in the animation handler function I actually do the interpolation and use the walk_transition value as the blendspace value.
#ANIMATION VARIABLES
onready var animation_tree = get_node("AnimationTree")
onready var animation_mode = animation_tree.get("parameters/playback")
var movement_state : Vector2
var walk_transition : Vector2
export var transition_speed : float = 5
func_ready():
walk_transition = Vector2(0, 0) #Initialize walk transition vector.
func _physics_process(delta):
_handle_movement(delta)
_handle_animation(delta)
func _handle_movement(delta):
movement_state = Vector2()
if can_move:
#DIRECTIONAL MOVEMENT
if Input.is_action_pressed("move_forward"):
movement_state.y += 1
if Input.is_action_pressed("move_backward"):
movement_state.y += 1 #Change to -= 1 when walk_b animation is implemented
if Input.is_action_pressed("move_left"):
movement_state.x -= 1
if Input.is_action_pressed("move_right"):
movement_state.x += 1
func _handle_animation(delta):
#DIRECTIONAL MOVEMENT
walk_transition = walk_transition.linear_interpolate(movement_state, acceleration * delta)
animation_tree.set("parameters/movement_state/blend_position", walk_transition)As stated, I only put the relevant pieces in this comment, if anyone is interested in the character controller for their own projects, I am more than happy to share it. If you have any question, let me know and I will help where I can.

I'm sure that would deserve it's own topic in the resource section. :)
