how to make my animation work

Question

i have this part of my code :

 if input_vector.x == 0:
    apply_friction()
    animplay.animation = "idle"

else:
    apply_accel(input_vector.x) 
    animplay.animation = "run"

    if input_vector.x > 0:
        animplay.flip_h = false
    elif input_vector.x < 0:
        animplay.flip_h = true

if is_on_floor():
    if Input.is_action_pressed("up"):
        vel.y = jump_height
else:
    animplay.play("anim_jump")
    if Input.is_action_just_released("up") and vel.y < jump_release:
        vel.y = jump_release

the problem is the animation for the jump doesn't want to work, there is just the 1st frame working, and if i want to change :

    animplay.play("anim_jump")

into :

    animplay.animation = "anim_jump"

the others animations will not work properly, they will also play only the 1st frame of their animations

Answer 1

Try:

Func set_animation():
    if input_vector.x != 0:
       animplay.play("run")
   elif vel.y != 0:
       animplay.play("anim_jump")
   else:
       animplay.play("idle")

put this function inside your process function.

this code has not been tested, so it may be wrong

sorry for the late response, i had to stop programming for a while.
I had to rewrite your code for me to work.

if input_vector.x != 0 and is_on_floor():
        animplay.play("run")
elif vel.y != 0:
    if Input.is_action_pressed("up"):
        animplay.play("jump")
    if Input.is_action_just_released("up"):
        animplay.animation = "jump"
        animplay.frame = 6

and i decided to change a little the beginnning of the old code i gave here.(your code is in the end)

if input_vector.x == 0:
    apply_friction()

else: 

    apply_accel(input_vector.x) 

    if input_vector.x < 0:
        animplay.flip_h = true
    elif input_vector.x > 0:
        animplay.flip_h = false

if is_on_floor():
    if Input.is_action_pressed("up"):
        vel.y = jump_force
else:
    if Input.is_action_just_released("up") and vel.y < jump_release:
        vel.y = jump_release

    if vel.y > 0:
        vel.y += additional_fall_gravity

var was_in_air = not is_on_floor() 

vel = move_and_slide(vel, Vector2.UP)


if input_vector.x != 0 and is_on_floor():
        animplay.play("run")
elif vel.y != 0:
    if Input.is_action_pressed("up"):
        animplay.play("jump")
    if Input.is_action_just_released("up"):
        animplay.animation = "jump"
        animplay.frame = 6
else:
    animplay.play("idle")

i can clearly say that my code has no sense, and is very painful to read lol, but in the end it worked, so thnks for your help.
