I am a beginner and been watching tutorials in YouTube for a 2D Space Shooter game. I plan to develop one for mobile phones. However, all videos I have seen used the keyboard for movement, so I searched for one creating a virtual joystick. I have seen one and successfully integrated it with the code. So now, I have a virtual joystick and a fire button (TouchScreenButton) which are both child nodes of a canvas layer. Since I cannot test both at the same time because there is only 1 mouse pointer, I have included a spacebar to also call the fire/attack functionality.
During testing in the Godot Engine and Android Virtual Device, there seems to have no issues at all, both buttons are working well separately. However, when I tested it in an actual mobile phone, whenever the player was moving using the joystick and then I press the fire button, the player will stop moving. It seems they cannot function at the same time. But when I hold down the fire button for continuous firing, then I move the player with the joystick it can move.
Here is the script for the joystick (Joystick.gd)
extends Area2D
onready var bigCircle = $BigCircle
onready var smallCircle = $BigCircle/SmallCircle
onready var max_distance = $CollisionShape2D.shape.radius
var touched = false
func _input(event):
if event is InputEventScreenTouch:
var distance = event.position.distance_to(bigCircle.global_position)
if not touched:
if distance < max_distance:
touched = true
else:
smallCircle.position = Vector2.ZERO
touched = false
func _process(_delta):
if touched:
smallCircle.global_position = get_global_mouse_position()
#clamp small circle
smallCircle.position = bigCircle.position + (smallCircle.position - bigCircle.position).limit_length(max_distance)
func get_velocity():
var joystickVelocity = Vector2.ZERO
joystickVelocity.x = smallCircle.position.x / max_distance
joystickVelocity.y = smallCircle.position.y / max_distance
return joystickVelocity
Here is the code snippet in the player scene where the joystick and fire button (named Attack) functions can be called:
func _physics_process(delta):
velocity = $UI/Joystick.get_velocity()
velocity = velocity.normalized() * speed
position += velocity * delta
# make sure sprite within screen, adjusted to size of image
var viewRect := get_viewport_rect()
position.x = clamp(position.x, 23, viewRect.size.x - 23)
position.y = clamp(position.y, 23, viewRect.size.y - 23)
# used for testing using spacebar for Fire
if Input.is_action_pressed("fire") and fireDelayTimer.is_stopped():
fireDelayTimer.start(fireDelay)
shoot.play()
for child in firingPositions.get_children():
var bullet := plBullet.instance()
bullet.global_position = child.global_position
get_tree().current_scene.add_child(bullet)
func _on_Attack_pressed():
if fireDelayTimer.is_stopped():
fireDelayTimer.start(fireDelay)
shoot.play()
for child in firingPositions.get_children():
var bullet := plBullet.instance()
bullet.global_position = child.global_position
get_tree().current_scene.add_child(bullet)
Basically, how can I implement where the player can continuously move while firing in a mobile phone (multitouch)
yeah, i’m having kinda of the same problem. i posted on reddit
