I made a kinematic body2d for my boss battle in godot and made it so that when the bullet which is an area 2d has a body entered it checks for the name then does something. This is my code:
This is my boss code:
extends KinematicBody2D
const ATTACK_THRESHOLD = 1
const ATTACKS = ["movingL", "movingR", "plus", "cross", "horizon"]
var _idle_count = 0
var _attack_set = ATTACKS
signal startin
var health = 1
onready var _anim_tree = $boostree
func increase_idle_count():
_idle_count += 1
if health == 0:
death()
if _idle_count > ATTACK_THRESHOLD:
_idle_count = 0
attack()
func _on_bosstrigger_start():
_anim_tree.set_condition("starting", true)
emit_signal("startin")
$boossoo.play()
func _ready():
randomize()
func attack():
var attack = _attack_set[randi()%_attack_set.size()]
_anim_tree.set_condition(attack, true)
func death():
_anim_tree.set_condition("die", true)
func _on_area2DE_area_entered(area):
if "bullet2" in area.name:
health -= 1
I used "area2DE" which was an area2d that was a child of the boss.
the "increase_idle_count()" function was put at the end of my idle animation.
.
I would think that the boss would do the death animation after getting shot but absolutely nothing happens. all the other animations work normally and will happen except for the death animation. I had spent the entire day trying different solutions and nothing had worked. Please help.

I have a Raycast2D where I want to detect collision with the enemy, but it does not collide at the end. What I'm saying is that it only detects collision at the place where it originates. Here is my code:
extends KinematicBody2D
export var speed = 200
var velocity = Vector2.ZERO
var enemy = 0
onready var navigation_agent = $NavigationAgent2D
onready var bullet = preload("res://Bullet.tscn").instance()
func _ready():
navigation_agent.connect("velocity_computed", self, "move")
$RayCast2D.global_rotation = self.global_rotation - 90
func _input(event):
if event.is_action_pressed("mouse_right"):
navigation_agent.set_target_location(event.get_global_position())
func _process(_delta):
if $RayCast2D.is_colliding():
if $RayCast2D.get_collider().is_in_group("enemy_ground_troop"):
enemy = $RayCast2D.get_collider()
velocity = Vector2.ZERO
ranged_attack()
if navigation_agent.is_navigation_finished():
return
velocity = global_position.direction_to(navigation_agent.get_next_location()) * speed
look_at(navigation_agent.get_next_location())
navigation_agent.set_velocity(velocity)
func move(velocity):
velocity = move_and_slide(velocity)
func ranged_attack():
add_child(bullet)
bullet.global_position = self.global_position
bullet.target = enemy.global_position
Could someone help me fix this?
are you debugging the physics collisions during runtime? you should be able to see if the line is intersecting or not.
look under Debug > Visible Collision Shapes
also try
$RayCast2D.force_raycast_update() inside of _process and see if that makes some difference.
Are you sure the raycast is enabled under the inspector?

I followed this tutorial: https://www.youtube.com/watch?v=7VzBHbG8sqo, and at 14:41, it shows how to do it in godot 3d, but I need it in godot 2d. He used "var newLoc = vehicle.global_transform.origin - 2*vehicle.transform.basis.x" to do that, but it doesn't work in 2d
There is a pretty simple solution for your problem, which does not even contain any math to work.
There is a Node called Position2D, which you can add to your Car Scene. Place it, where you want your character should stand after leaving the vehicle (so as a driver on the left side of your car)
Because the node is in your car scene it will move along with the car and rotate as well, so its always right next to your car.
All we need to do now is getting the global_position of the Position2D and setting the global_position of our player to it.
To make it easier to receive the global_position of the Position2D Node, we can add a function to the car which returns exactly that. Saying your Car Scene looks like this:
Vehicle
Sprite
ExitPosition (Our Position2D node. Renamed for clearity)
The function in our vehicle.gd could be like this:
func get_exit_location() -> Vector2:
return $ExitPosition.global_position
As I see it you have a variable named vehicle in your player code, which points to your car. So now, when you want to leave the car you can set the player position like this:
## Calling inside player code
global_position = vehicle.get_exit_location()
Keep in mind, that both ways (the one in the video and this one here) will make problems if there is something at the point your trying to place your player. So always check if your player can be at that position.
what is happening is that my "enemy" is not following the "player", when my player enters the detection area the "enemy" continues straight ahead (to the left).
thank you, if you understand something or need more information let me know

enemy code
enemy code:
const EnemyDeathEffect = preload("res://Bots/EnemyDeathEffect.tscn")
export var MAX_SPEED = 60
export var ACCELERATION= 25
export var FRICTION = 700
enum {
IDLE,
WANDER,
CHASE
}
var velocity = Vector2.ZERO
var knockback = Vector2.ZERO
var state = CHASE
var path: PoolVector2Array
onready var sprite = $AnimatedSprite
onready var stats = $Stats
onready var playerDetectionZone = $PlayerDetectionZone
func _physics_process(delta):
knockback = knockback.move_toward(Vector2.ZERO, FRICTION * delta)
knockback = move_and_slide(knockback)
match state:
IDLE:
velocity = velocity.move_toward(Vector2.ZERO, FRICTION * delta)
seek_player()
WANDER:
pass
CHASE:
var player = playerDetectionZone.player
if player != null:
var direction = (player.position - global_position).normalized()
velocity = velocity.move_toward(direction * MAX_SPEED , ACCELERATION * delta)
print(direction)
else:
state = IDLE
sprite.flip_h = velocity.x > 0
velocity = move_and_slide(velocity)
func seek_player():
if playerDetectionZone.can_see_player():
state = CHASE
func _on_Hurtbox_area_entered(area):
stats.health -= area.damage
knockback = area.knockback_vector * 100
func _on_Stats_no_health():
queue_free()
var enemyDeathEffect = EnemyDeathEffect.instance()
get_parent().add_child(enemyDeathEffect)
enemyDeathEffect.global_position = global_position
I only possible culprit I see is this line:
var direction = (player.position - global_position).normalized()
Here player.position is in its parent local coordinates, while global_position as the name says is in global coordinates. You want this instead:
var direction = (player.global_position - global_position).normalized()
I see this is the way you have on the linked image.
Or if you prefer:
var direction = global_position.direction_to(player.global_position)
Aside from that, it could be that it is changing direction too slowly. Which - given the code - is the same as saying that the ACCELERATION is low, but that is for you to tweak.
I guess it is worth debugging that playerDetectionZone is getting the player, and the CHASE is working correctly.
Common approaches include using a breakpoint, or print. You already have a print for direction. Try also printing player to check the enemy is chasing what you expect it to chase.
For this particular case I also suggest to go to the run the project from the editor, and then go to the Scene panel on the Remote tab, and select the enemy. That would allow you to the properties of the enemy on real time on the Inspector. You should see the state change to CHASE (which would have the value 2), and velocity should also steadily change.
Enabling "Visible Collision Shapes" form the debug menu may also help debugging.
If it is not working, double check the playerDetectionZone has monitoring enabled. Also check that the collision_mask of the playerDetectionZone and the collision_layer of the player are correct.
I'm trying to make a 2d platformer where you spawn an object and try to jump on it in the air before it falls.
the problem is when I try to spawn the tile it doesn't spawn where Is the cursor at
it adds a relative value to the position that I don't know how to get rid of it.
you see when I try to instance a scene it takes the cursor position and viewport value into account but then something happens and I fount the object spawning way too far.
see where is the cursor at and where did the tile spawn
, same thing here
, and here
-here is how I'm grouping the nodes and scenes-
and this is the script I'm using, it's in the player1 scene

this the same problem in Godot form check it out if possible in case someone answered there

If you don't have an extra Viewport
My first intuition is to get get_global_mouse_position and set global_position. That way you don't have to deal with any relative positioning:
ABT1.global_position = get_global_mouse_position()
Alternatively, you can check if the event is InputEventMouse, make it local with make_input_local, and get InputEventMouse.position from it:
func _input(event):
if event is InputEventMouse and event.is_action_pressed("click"):
var ABT1 = AB1.instance()
add_child(ABT1)
event = make_input_local(event)
ABT1.position = event.position
This approach would make it easier to then add touch support, because it does not rely on any function that gives you the mouse position. See my answer for Holding screen touch in godot.
If you have an extra Viewport
First of all, make sure you put your Viewport inside a ViewportContainer (otherwise it does not get input, see _input not called for a node inside a Viewport). Then we can use that ViewportContainer to get our coordinates.
Something like this:
func _input(event):
if event is InputEventMouse and event.is_action_pressed("click"):
var ABT1 = AB1.instance()
add_child(ABT1)
var container = find_parent("ViewportContainer") as ViewportContainer
if container != null:
event = container.make_input_local(event)
event = make_input_local(event)
ABT1.position = event.position
Notice there I'm using the function find_parent. It matches by name of the Node, not by type. Another approach you can try is using get_viewport().get_parent().
And yes, that should work regardless of stretch mode.
I am currently working on an enemy spawner for a 2D arena wave spawner game in Godot.
I have an export(resource) variable that allows me to insert a spawning animation into the scene.
My question is: How do I play said animation?
I have created comments in my code that explains how it is set up. The two possible ways I think it could be solved is either by
Inserting a function where I commented it, that takes the previously determined position value and playing that animation at those coordinates. However I do not know how to play the animation as an export(resource) var.
Play the animation not as a function using the position value... but its still the same question.
Thanks!
extends Node2D
export(NodePath) var node_path
const WIDTH = 254
const HEIGHT = 126
export(Resource) var ENEMY
export(Resource) var SPAWNANIMATION
var spawnArea = Rect2()
var delta = 3
var offset = 0.5
#Creates the spawnArea and randomizes positions for the enemy to spawn
func _ready():
randomize()
spawnArea = Rect2(0, 0, WIDTH, HEIGHT)

#Spawns an Enemy at said Random position
func spawnEnemy():
var position = Vector2(randi()%WIDTH, randi()%HEIGHT)

return position

You'll need an AnimationPlayer node that you add_animation() resource when _ready(). Here's a code example:
func _ready():
$AnimationPlayer.add_animation('spawn', SPAWNANIMATION)
func EnemySpawningAnim(position):
# ... logic to handle position
$AnimationPlayer.play('spawn')
