My jump animation dont work

Question

I don't know how to make my jump animation work in my code and besides it doesn't work it also makes my jump code not work.

Here´s my code:

extends KinematicBody

var verticalvelocity = 0
var gravity = 50
var direction = Vector3.FORWARD
var velocity = Vector3.ZERO
var strafedir = Vector3.ZERO

var jumpmagnitude = 25
var jumpblend = "parameters/jumpblend/blendposition"
var agtransition = "parameters/agtransition/current"
var agtransitionactive = "parameters/jump_blend/acitve"

var fligthmagnitude = 2
var velocityfly = 0

var movementspeed = 0
var walkspeed = 3
var runspeed = 12
var acceleration = 7
var angularacceleration = 7
var superspeed = 50
var speedincrease_increment = 1

func physicsprocess(delta):
if Input.isactionpressed("Forward") || Input.isactionpressed("Backward") || Input.isactionpressed("Left") || Input.isactionpressed("Right"):

    var h_rot = $Camroot/h.global_transform.basis.get_euler().y 

    direction = Vector3(Input.get_action_strength("Left") - Input.get_action_strength("Right"),
                0,
                Input.get_action_strength("Forward") - Input.get_action_strength("Backward")).rotated(Vector3.UP,h_rot).normalized()

    if Input.is_action_pressed("Sprint"):
        movement_speed = run_speed
        $AnimationTree.set("parameters/iwr_blend/blend_amount", lerp($AnimationTree.get("parameters/iwr_blend/blend_amount"), 1 , delta * acceleration))
    else: 
        $AnimationTree.set("parameters/iwr_blend/blend_amount", lerp($AnimationTree.get("parameters/iwr_blend/blend_amount"), 0 , delta * acceleration))
        movement_speed = walk_speed
else :
    $AnimationTree.set("parameters/iwr_blend/blend_amount", lerp($AnimationTree.get("parameters/iwr_blend/blend_amount"), -1 , delta * acceleration))
    movement_speed = 0

# faz com que o botão que foi pressionado ative uma ação e se for pressionado de novo desativa a ação


if is_on_floor():

    if $AnimationTree.set(ag_transition,1):
        if $AnimationTree.get("ag_transition_active"):
            if Input.is_action_pressed("Jump"):
                vertical_velocity = jump_magnitude 

        else :
            $AnimationTree.set(ag_transition,0)
            $AnimationTree.set(jump_blend, lerp($AnimationTree.get(jump_blend), vertical_velocity/jump_magnitude, delta * 10 ))

if gravity <0:
    gravity = 50

if Input.is_action_just_pressed("Flight"):
    if gravity == 0:
        gravity = 50
        vertical_velocity = 0
        run_speed =12
        walk_speed = 3
    else:
        gravity = 0
        vertical_velocity = delta * gravity 
        run_speed = 50
        walk_speed = 5

if gravity ==0 and !is_on_floor():
    if Input.is_action_pressed("Up"):
        velocity.y += fligth_magnitude * 2
    if Input.is_action_pressed("E"):
                velocity.y -= fligth_magnitude * 2
    elif is_on_floor():
        velocity.y = 0






velocity = lerp(velocity,direction * movement_speed, delta * acceleration)

move_and_slide(velocity + Vector3.UP * vertical_velocity,Vector3.UP)

if !is_on_floor():
    vertical_velocity -= gravity * delta 
else:
    vertical_velocity = 0

$SimplePlayerarma.rotation.y = lerp_angle($SimplePlayerarma.rotation.y,atan2(direction.x,direction.z), delta * angular_acceleration)

Comments

I can see you're assigning values to the parameters of the AnimationTree just fine but your entire code without much else makes it difficult to figure out what's happening.

Can you give more details besides "not work"? Do any of your animations still play when you select the AnimationTree and try to activate the animations in the AnimationTree window on the bottom?

Also, have you tried following any specific tutorials with an AnimationTree before?
