Making a bullet disappear when it has been shot/ thrown after a short while.

UnknownUser

Hi, I code in GDScript. I am making a game where you throw nuts at enemies, and if you don't hit the enemy the nut will kind of bounce off walls a little and roll around, but they never end up disappearing that way and you get alot of lag as then never disappear. If anyone can help out, it would be appreciated. I'm thinking after instantiating the bullet/nut, it can start a timer and then delete the nut after that timer runs out. Thanks! :)

I'd go for the timer route, maybe using a variable and delta so you can pause the timer if you need. Something like this is how I'd approach the issue:

var timer = 0.0
var timer_active = false
const TIMER_TIME = 20 # in seconds

func _process(delta):
	if (timer_active):
		timer -= delta
		if (timer <= 0):
			timer_active = false
			queue_free()

func start_timer():
	if (timer_active == true):
		return # don't start the timer twice!
	timer = TIMER_TIME
	timer_active = true

So I'd put this into the nut's code and when it is instantiated, it will run all of this?

Correct, though you'll want to call start_timer in the _ready function if you want the timer to start once the object is instantiated.

Thank you so much! This has really helped, the nuts fall quicker, and they then disappear after a short while! I'm just gonna make a nuts breaking animation so that they don't just disappear. Thanks again @TwistedTwigleg !
