So I just finished Heartbeast’s Action rpg tutorial video and I decided to add some features on my own. one of it is the knockback of the player that got hit by the enemy. so I used this code.
var hitKnockBack = Vector2.ZERO
for the player hit knock back force, and then for the move state I changed it as following:
func move_state(delta):
var input_vector = Vector2.ZERO
input_vector.x = Input.get_action_strength("ui_right") - Input.get_action_strength("ui_left");
input_vector.y = Input.get_action_strength("ui_down") - Input.get_action_strength("ui_up");
input_vector = input_vector.normalized()
if input_vector != Vector2.ZERO:
roll_vector = input_vector
swordHitbox.knockback_vector = input_vector
animationTree.set("parameters/idle/blend_position", input_vector)
animationTree.set("parameters/Run/blend_position", input_vector)
animationTree.set("parameters/Attack/blend_position", input_vector)
animationTree.set("parameters/Roll/blend_position", input_vector)
animationState.travel("Run")
velocity = velocity.move_toward(input_vector * MAX_SPEED, ACCELERATION * delta)
else:
animationState.travel("idle")
velocity = velocity.move_toward(Vector2.ZERO, FRICTION * delta)
hitKnockBack = hitKnockBack.move_toward(Vector2.ZERO, 500 * delta)
hitKnockBack = move_and_slide(hitKnockBack)
move(delta)
if Input.is_action_just_pressed("roll"):
state = ROLL
if Input.is_action_just_pressed("attack"):
state = ATTACK
then when player’s hurtbox got entered by the bat I take the area that entered the player’s hurtbox which is the bat’s hitbox then I take the parent which is the bat’s kinematicbody2D and take the velocity of it and assign it to player’s hitKnockBack like this:
func _on_Hurtbox_area_entered(area):
stats.health -= area.damage
hurtBox.start_invincibility(1)
hurtBox.create_hit_effect()
hitKnockBack = area.get_parent().velocity * 6
var playerHurtSound = PLAYERHURTSOUND.instance()
get_tree().current_scene.add_child(playerHurtSound)
now I tested this one and it works. but I want to know if there’s a better way of doing this? because the multiplier 6 there seems too random for me but that’s what works for me. if I put something like 500 or even 10 it seems that the knockback force will be too massive.
this is how the bat codes look:
export var accelerator = 70
export var max_speed = 20
export var friction = 500
export var wander_target_range = 8
func accelerate_towards_point(position, delta):
var direction = global_position.direction_to(position)
velocity = velocity.move_toward(direction*max_speed, accelerator*delta)
sprite.flip_h = velocity.x < 0
so is there any other way I can do the player knockback better?
