If you think your iPhone is secure, think again. VPNs on iOS have been leaking traffic for 2 years, and Apple has known about it and done nothing. Their whole security stance is a front.

I think I remember being told that existing connections were an issue with most vpns, and you had to start them with your network connection to be sure. If I was apple and someone demanded an easier way to kill all network connections, I'd probably be thinking of how many angry complaints they'd get if someone used it carelessly. Not to mention, if you have any sort of cell connection, you're broadcasting your location and activity to everyone in the area anyway. I wonder if android vpns work better.

duane I wonder if android vpns work better.

AFAIK, yes. At least I haven't heard of any huge security flaws.

Guys what's a good Python book or books you can recommend ? There's a lot, almost too much out there it appears.

Should be OS agnostic (or Linux if it must be) and not need any frameworks or specific IDEs. I also don't need the very basic hug-your-pc introductions :-) Examples and exercises are nice to have. I would also prefer as up-to-date as possible.

Any recommendations, also online reading (videos not so much) if you know something ?

There's for instance Eric Matthes, Python Crash Course from no starch press to arrive in a new edition in October. Has anyone a verdict about an earlier version, maybe ?

I'm now using Godot 3.5 and my first person controller keeps sliding down slopes. This has nothing to do with the code for my gravity, because I know that the Is_on_floor function is working just fine. It's just that it slipes when it touches anything. Does anyone know how to fix this problem? Here is the movement code in it's entirety:

func _input(event):
	if event is InputEventMouseMotion:
		rotate_y(deg2rad(-event.relative.x * mouse_sensitivity))
		head.rotate_x(deg2rad(-event.relative.y * mouse_sensitivity))
		head.rotation.x = (clamp(head.rotation.x, deg2rad(-90),deg2rad(90)))
		
func _physics_process(delta):
	direction = Vector3();var snap = Vector3.DOWN if not jumping else Vector3.ZERO
	var gravity_resistance = get_floor_normal() if is_on_floor() else Vector3.UP
	
	if not is_on_floor():

		fall -= (gravity * gravity_resistance) * delta
		move_and_slide_with_snap(fall,snap,Vector3.UP,true,1,deg2rad(50),false)

	if Input.is_action_just_pressed("ui_cancel"):
		Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)
	if jumping and is_on_floor():
		jumping = false
	
	if Input.is_action_pressed("move_forward"):
		direction -= transform.basis.z
	elif Input.is_action_pressed("move_backward"):
		direction += transform.basis.z
	if Input.is_action_pressed("move_left"):
		direction -= transform.basis.x
	elif Input.is_action_pressed("move_right"):
		direction += transform.basis.x
	if Input.is_action_just_pressed("jump") and is_on_floor():
		jumping = true;fall.y = jump
	
	direction = direction.normalized()

	velocity = velocity.linear_interpolate(direction * speed,acceleration * delta)
	velocity = move_and_slide_with_snap(velocity,snap,Vector3.UP,true,1,deg2rad(45),false)

If you want to post code on the forum, you have to type 3 tildes ~~~ on a line by themselves directly above and directly below the posted code.

Audiobellum

cybereality I'm a little bit confused. When I originally post that code, I didn't intentionally put the 3 tildes there but, now I see it. I thought that it auto corrected, because it looked like I used the 3 tildes in the preview. It's only after I was this message that I tried to edit the post to put in the 3 tildes but, it was already there. Did someone else edit my post? Not that I'd have a problem with that, in this situation; I just want to know.

cybereality

velocity y should be set to zero when is_on_floor() is true (before applying the move and slide). Also, you only want to do one move_and_slide call per physics step. While sometimes it works to do it multiple times, this can cause problems and may be the issue. If you need extra calculation, just adjust the velocity value however you want, and then call move and slide at the end.

Audiobellum

cybereality Yeah, I did fix the issue with the velocity and here is what my code looks like:

	if not is_on_floor():
		fall.y -= gravity * delta
		move_and_slide_with_snap(fall,snap,Vector3.UP,true,2,deg2rad(50))
	if is_on_floor() or jumping == false:
		velocity.y = 0

I caused my controller to work better but, I do still have an incredibly small issue. When moving up slopes, the controller stops when I'm no longer holding down the move keys( as I've intented). When moving down slopes, the controller doesn't stop immediately when I'm no longer holding down the movement keys. Instead, the controller moves and jitter a little bit before stopping. I've heard other indiedev complain that their FPS controllers moves faster down slopes than up slopes but, I don't think that's the problem I'm facing. It's an incredibly small problem but, I don't know how to fix it. I also don't know how to call only a single move_and_slide for both moving and jumping but, I'm not even sure to what extend that is apart of the problem yet.

Megalomaniak

Audiobellum Did someone else edit my post?

According to the history notice on the 'Edited' element on the post it was @cybereality 10h ago, not sure if the on hover tooltip response only shows to me since I'm an admin or if it'd show to others too(I'd expect the latter).

cybereality

Yeah, I edited the post so I could read it. The jitter may be cause by the two move and slides. Also, it's good to simulate friction. Though this is not physically accurate, I usually do something like this right after moving the player.

velocity *= 0.985

You can tweak the number, between 0.99 and 0.98 works best.

Audiobellum

cybereality I've tested but, move and slides in isolation from one another( by temporarily commenting them out). The I commented out was the what that I had to do with the gravity, yet the problem still exist. My controller would move up the slope 'til they "levitate"( as oppose to falling off the edge). However, the controller can still move back down the slope, even though there is supposedly no gravity. When stopping the character on the slope, while it's was moving down the slope, the same problem araised. I also have this other problem when I'm running the gravity code, that problem being that my controller can't jump from off a slopes; this problem came up with I used messing with the velocity.y.

cybereality

Megalomaniak not sure if the on hover tooltip response only shows to me since I'm an admin or if it'd show to others too

It shows for everyone. I tested in a private window. Good to know.

Audiobellum

cybereality Yeah, I just noticed it now.

cybereality

Audiobellum yet the problem still exist

The code is kind of weird. I don't know how to fix it without altering a lot of how it works. But I never used slide with snap, I think move and slide works well enough, the snap is not needed in most cases (but it depends on the game). Also, you are checking is on floor like 4 times, when it should only really be checked once. So there is some error in the logic in terms of jumping. If you are calling any function so many times, it means the logic doesn't make sense. I also don't understand the use of fall. Everything should use velocity, you should not have two movement vectors (another sign of a logic error).

cybereality

Nice. I guess they were losing money or something, but now streaming finally works with the VPN on Linux. So I don't have to watch on my Windows machine. So far it seems Netflix, YouTube, and Amazon have conceded. The bad news is only at 480p. I guess I'll take what I can get.

Audiobellum

The only time I can jump when I'm on a slope, is when moving down the slope which is weird.

Audiobellum

cybereality So I’ve managed to solve the whole slope problem by using less vectors but, new I have new problems. My gravity is incredibly slow when multiplied by delta but, is unnaturally fast without it(the value for the gravity is 9.5). Jump barely manages to get the controller of the ground( the value for jump is 7).The code looks like this:

func _physics_process(delta):
	direction = Vector3()
	if not is_on_floor():
		velocity.y -= gravity  * delta
	if Input.is_action_just_pressed("ui_cancel"):
		Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)
	if Input.is_action_pressed("move_forward"):
		direction -= transform.basis.z
	elif Input.is_action_pressed("move_backward"):
		direction += transform.basis.z
	if Input.is_action_pressed("move_left"):
		direction -= transform.basis.x
	if Input.is_action_pressed("move_right"):
		direction += transform.basis.x
	
	if Input.is_action_just_pressed("jump") and is_on_floor():
		direction.y += jump

	direction = direction.normalized()
	velocity = velocity.linear_interpolate(direction * speed,acceleration * delta)
	move_and_slide(velocity,Vector3.UP,true,1)

Now I can make the gravity behave more realistic by changing it’s value but, this was never a problem before;I hope that there is a better solution. Even though I was originally following a tutorial, I think the reason why I used multiple vectors and called move_and_slide twice was because the vectors used for movement( direction and velocity) where being used for some short of smooth acceleration while calling another move_and_slide for the gravity ensured it had a different type of “physics” that won’t interfere with the movement or vice versa.
Do you know how the make the gravity and jumping work again? 🥺 🙏

Audiobellum

cybereality Okay, so I've completely overhauled my moving code by following a tutorial by GDquest on movement. I wish I followed this tutorial sooner, it's the best and I also learned some new syntax tricks. I won't recommend the tutorial to complete beginners though, as I had to adapt the code to satisfy my first person needs specifically( something the tutorial doesn't address).Here it is for reference:

Now my code looks like this:

func _physics_process(delta):
	if Input.is_action_just_pressed("ui_cancel"):
		Input.set_mouse_mode(Input.MOUSE_MODE_VISIBLE)
	
	var move_direction = Vector3.ZERO
	move_direction.x = Input.get_action_strength("move_right") - Input.get_action_strength("move_left")
	move_direction.z = Input.get_action_strength("move_backward") - Input.get_action_strength("move_forward")
	move_direction = move_direction.rotated(Vector3.UP,self.rotation.y).normalized()
	velocity.x = move_direction.x * speed
	velocity.z = move_direction.z * speed
	velocity.y -= gravity * delta
	var just_landed = is_on_floor() and snap_vec == Vector3.ZERO
	var is_jumping = is_on_floor() and Input.is_action_just_pressed("jump")
	if is_jumping:
		velocity.y = jump
		snap_vec = Vector3.ZERO
	elif just_landed:
		snap_vec = Vector3.DOWN
	velocity = move_and_slide_with_snap(velocity,snap_vec,Vector3.UP,true)

It works better but there is only one small problem left; the controller slightly slides up slopes a little bit before stopping.

Just for fun spculation and story idea generation, what do you devs think is the cause behind the mysterious vanishings of air planes and such in the Bermuda Triangle?

I have a few theories- ranging from supernatural activity, to a secret pirate base that has never been discovered for years and grew powerful, and that kidnaps people.

Anythoughts?

Nerdzmasterz Just for fun spculation and story idea generation, what do you devs think is the cause behind the mysterious vanishings of air planes and such in the Bermuda Triangle?

You can search for Charles Berlitz and Erich von Däniken. These stories are all made up. No such triangle exists where any statistics sees more ships/planes vanishing than anywhere else in the world.

I'm as sorry as possible ...

For a game story, of course, anything goes. Just go ahead, aliens, long lost underwater civilisation, sunken Atlantis, dimensional doors (trap doors in the water presumably), ...

cybereality

My guess is they got sucked into another dimension. They are probably on like some LOST island right now.
