Hi.
after adding touchscreen controller to scene, 2 issues appeared:
- after releasing touchscreen controller, character keeps moving and does not stop and it affects on keyboard input key as well (i could fixed this with “is_action_just_released” command for keyboard’s input keys, but it wasn’t a general solution for this problem)
- character change its direction in U turn and not instantly.
how should i fix these problems? (especially first one), Thank You.
(I used controller codes from godot’s templates made by Jakub Grzesik)
codes for moving KinematicBody2D:
func _physics_process(delta):
if Input.is_action_pressed("ui_right"):
velocity.x += 1
if Input.is_action_pressed("ui_left"):
velocity.x -= 1
if Input.is_action_pressed("ui_down"):
velocity.y += 1
if Input.is_action_pressed("ui_up"):
velocity.y -= 1
velocity += outer_velocity
if velocity.length() > 0:
velocity = velocity.normalized()*speed*delta
motion = move_and_collide(velocity)
if (motion):
motion = move_and_slide(velocity * 60)
#### Touch Controller Function
func analog_force_change(inForce, inStick):
if(inStick.get_name()=="Directions"):
if inForce.length() < 0.1:
outer_velocity = Vector2(0,0)
else:
outer_velocity.x = inForce.x
outer_velocity.y = -inForce.y
#Convert outer velocity to 0 , 1 , -1
outer_velocity.x = int(round(outer_velocity.x))
outer_velocity.y = int(round(outer_velocity.y))
outer_velocity.x = stepify(outer_velocity.x, 1)
outer_velocity.y = stepify(outer_velocity.y, 1)
#print(outer_velocity)
