I want to implement a system where when the player gets hit with a bullet that is fired, the player is pushed back. I’m unsure of how to implement this because I want the player to be pushed back and his movement shouldn’t override the knockback received.
Here is the code for the projectile:
extends Area2D
const SPEED = 800
var velocity = Vector2()
var direction = 1
func _ready():
pass
func start():
position = Vector2()
func set_bullet_direction(dir):
direction = dir
if dir == -1:
$AnimatedSprite.flip_h = true
func _physics_process(delta):
velocity.x = SPEED * delta * direction
translate(velocity)
$AnimatedSprite.play("BulletShoot")
func _on_VisibilityNotifier2D_screen_exited():
queue_free()
func _on_Bullet_body_entered(body):
if "Player1" in body.name:
#KNOCKBACK
pass
if "Player" in body.name:
queue_free()
Code for the player:
extends KinematicBody2D
const UP = Vector2(0,-1)
var velocity = Vector2()
const SPEED = 400
const GRAVITY = 60
const JUMP = -900
const BULLET = preload("res://Scences/BulletPistol.tscn")
var inAir = false
var holdingWeapon = false
func _physics_process(delta):
velocity.y += GRAVITY
if Input.is_action_pressed("p1_right"):
$AnimatedSprite.play("Run")
$AnimatedSprite.flip_h = false
if sign($Position2D.position.x) == -1:
$Position2D.position.x *= -1
velocity.x = SPEED
elif Input.is_action_pressed("p1_left"):
$AnimatedSprite.play("Run")
$AnimatedSprite.flip_h = true
if sign($Position2D.position.x) == 1:
$Position2D.position.x *= -1
velocity.x = -SPEED
else:
velocity.x = 0
if inAir == false:
$AnimatedSprite.play("Idle")
if is_on_floor():
inAir = false
else:
inAir = true
if velocity.y < 0:
$AnimatedSprite.play("Jump")
elif velocity.y > 0:
$AnimatedSprite.play("Fall")
if Input.is_action_just_pressed("p1_up"):
if inAir == false:
velocity.y = JUMP
inAir = true
if Input.is_action_just_pressed("p1_action"):
if holdingWeapon == true:
var bullet = BULLET.instance()
if sign($Position2D.position.x) == 1:
bullet.set_bullet_direction(1)
else:
bullet.set_bullet_direction(-1)
get_parent().add_child(bullet)
bullet.global_position = $Position2D.global_position
velocity = move_and_slide(velocity, UP)
pass
