  • Whats the best way to make a bullet?

I needed a way to make a bullet but i have no idea what node to use i was using a kinematic body but im having all sorts of problems such as firing it and others. Thanks in advance

Use RigidBody instead.

Make a bullet scene that has your bullet image and a script like below. In your player node or other node, connect the hit() signal to a function that determines whether the bullet should do damage or not. Instantiate a bullet scene, determine the location you want to spawn it(e.g. end of gun) and the direction you want it to travel and make this a matrix. Pass this matrix to the shoot() function in the bullet.

Basic example, but I think it should give you a good starting point. Let me know if this works for you.

extends RigidBody2D
    
var damage = 10
var vel = Vector2(100,0)
signal hit(body, damage)
    
func _ready():
	set_fixed_process(true)
	set_contact_monitor(true)
	set_max_contacts_reported(1)
	connect("body_enter", self, "contact")
    
func _fixed_process(delta):
	pass
    
func shoot(var matrix):
	set_transform(matrix)
	set_linear_velocity(vel)


func contact(body):
	if body.is_in_group("Enemy"):
		emit_signal("hit", body, damage)
	destroy()

func destroy():
	#play explosion animation and sound
	queue_free()

func _on_Timer_timeout():
	#Destroy after short time in case it never hits anything
	destroy()

*editted Vector2D, some typos, and function argument order**
