Making shogun bullet

Question

Hi I try to make a shotgun bullet and I want to decide to change the size of the dispersion and a damge reduce by distance the bullet do and fix it minimum and max damage to 1 for the reduce damage by distance.

script for bullet 1:

extends Area2D

const speed = 900

export(int) var damage = 10
var velocity = Vector2(1,1)

func shootatmouse(startpos):
self.globalposition = startpos
var direction = (getglobalmouseposition() - startpos).normalized()
self.linearvelocity = -direction * speed

func physicsprocess(delta):
velocity.x = speed * delta
velocity.y = speed * -delta
translate(velocity)
setposition(getposition()+velocity*-delta)

script bullet 2:

extends Area2D

const speed = 900

export(int) var damage = 10
var velocity = Vector2()

func shootatmouse(startpos):
self.globalposition = startpos
var direction = (getglobalmouseposition() - startpos).normalized()
self.linearvelocity = direction * speed

func physicsprocess(delta):
velocity.x = speed * delta

translate(velocity)
set_position(get_position()+velocity*delta)

script bullet 3:

extends Area2D

const speed = 900

export(int) var damage = 10
var velocity = Vector2(-1,1)

func shootatmouse(startpos):
self.globalposition = startpos
var direction = (getglobalmouseposition() - startpos).normalized()
self.linearvelocity = -direction * speed

func physicsprocess(delta):
velocity.x = speed * delta
velocity.y = speed * delta
translate(velocity)
setposition(getposition()+velocity*-delta)
Thank for helping me :)

Hello! Why you have 3 different bullet nodes?

---

yeah a use three bullet to give the "effect" of dispersion of a shotgun bullet.It just a part of the design of the weapon.

Edit:actually I find the solution for the dispersion but anyway could you just explain me how to to the damage reduce by distance whit a max damage and a minimum damage.

Answer 1

You could make variable damage like this:

var damage = 10.0
const damage_minimum = 1.0
const damage_reduction = 5.0

func _process(delta):
    damage -= damage_reduction * delta
    if damage < damage_minimum 
        damage = damage_minimum 

Then play around with the values of the variables to make an effect you like.
The longer the bullet will fly, the less the damage will it make, down to a minimum of 1.

You could also adjust the function to be nonlinear by, for example, reducing damage by a percentage instead of fixed value.
