5th dnd – Does Shadow Lore require the bard to physically whisper, and can the target or a nearby creature detect it?

A Level 14 College of Whispers Bard acquires the following class feature:

Know of the shadowAs an action, you magically whisper a phrase that only a creature of your choice within 15 yards of you can hear. The target must make a Wisdom save roll against your spell and save DC. It succeeds automatically if it does not share a language with you or if it does not hear you. On a successful save roll, your whisper sounds like an unintelligible murmur and has no effect.

If the target fails its save roll, it is charmed by you for the next 8 hours or until you or your allies attack or damage it. He interprets the murmurs as a description of his most mortifying secret.

Although you have no knowledge of this secret, the target is convinced to know it. Although charmed in this way, the creature obeys your orders lest you reveal its secret. He will not risk his life for you or fight for you unless he was already inclined to do it. He grants you favors and gifts that he would offer to a close friend.

When the effect ends, the creature does not understand why she kept you in such fear.

(p.16, Xanathar's guide)

When using Shadow Lore, does the bard physically whisper something that only the target can hear, or is it more of a telepathic murmur than the target hears?

Could the target, or a nearby creature, say that Shadow Lore was used and potentially who used it?

Android "Nearby" (configure the device nearby) – "No devices found"

trying to migrate from one mobile to another. Older is 7.0 and the newest is 9.x Pie.

Both devices have bluetooth and wi-fi alight. In fact, one sees each other on a Bluetooth scan and they are paired.

It's just that the nearby The service (?) Of his call used to configure a new device just does not work.
I have launched simultaneously from both phones – the tag "find nearby devices" … none of the phones have "found". I have repeated the same thing separately- In vain.

Why does this happen and what does it take for this hardware to work properly?

Do you use an app to find people nearby? [on hold]

2d – Unity Colliders – How to detect nearby objects without my detection ranges detecting each other

How to get the types of both colliders in a trigger overlap message like OnTriggerExit2D (Collider2D other)?


  • objects A and B both have a BoxCollider2D and CircleCollider2D Components.

  • Then, object A enters one of the trigger colliders of object B.

  • I can get object BThe type of collider with the is operator.

How can I get the type of collider from A?

The reason I want this is that I only want collisions where object Aof CircleCollider2D touch object Bof BoxCollider2D.

void OnTriggerExit2D (Collider2D other)
if (other is BoxCollider2D)
// Do Code

Here's a chart of what I want: I just want to record overlaps of triggers from CircleCollider2D at BoxCollider2D. With the is operator, I can safely remove all collisions CircleCollider2D but collisions between two BoxCollider2D rest, what I do not want.

+ ------------------ + --------------- + -------------- ---- +
| Column row | BoxCollider2D | CircleCollider2D |
+ ------------------ + --------------- + -------------- ---- +
| BoxCollider2D | No | No |
| CircleCollider2D | Yes | No |
+ ------------------ + --------------- + -------------- ---- +

The real question was to detect nearby objects without detecting the detection range.

android – The best way to exchange data from one to several phones nearby

I want to create an application where several people close to an Android or iOS phone can exchange a small amount of data with one person. Thus, one person is the group leader and passes the name of the group to the other participants. I was thinking of using NFC but I have not been able to know if iphones can transmit a value (it seems they can now read NFC tags – but I have never seen writing this data). I could use QR codes (the manager then displays the QR image and the others scan this image). Or I believe there are blue-tooth and wifi options. But I want it to be a very simple action – to activate the bluetooth / wifi and connect the sound as if they were too long. Alternatives, suggestions?

My camera does not focus on nearby objects

The minimum focus distance is the closest you can get to a subject and get the focus on that subject. This is a property of your lens, not your camera.

Please see the specifications of this Canon 24-105mm lens: https://www.bhphotovideo.com/c/product/1274709-REG/canon_ef_24_105mm_e_4l_is.html

You will notice that the MFD is 1.48 feet tall. This means that you can not physically focus on an object closer to you than 1.48 ft.

If you are trying to approach a very small object, this type of photography calls Macrophotography. There are macro lenses specifically designed for closer-to-average tuning. For example, the MFD of this 100mm macro lens is 11.81 inches: https://www.bhphotovideo.com/c/product/647011-USA/Canon_3554B002_EF_100mm_f_2_8L_Macro.html

In addition to obtaining a dedicated macro lens, one can use extension tubes with any purpose to allow for more precise focus, at the cost of not being able to focus too far. Your distance depends on the length of the tube and the lens you are using. The calculations become quite complex, especially with the zooms. The normal advice is simply: experiment.

lighting – Simulates the appearance of an aircraft illuminated by a nearby point source

I would like to simulate the appearance of a reflective flat surface illuminated by a nearby point source.

Graphics3D[{Lighting -> {{"Point", White, {0, 0, 1}}},
     {{-10, -10, 0}, 
      {-10, 10, 0}, 
      {10, 10, 0}, 
      {10, -10, 0}, 
      {-10, -10, 0}}]}
PlotRange -> {{-10, 10}, {-10, 10}, {0, 10}},
Axes -> True,
AxesLabel -> {"x", "y", "z"}]

plane illuminated by a point source

Note that the single point source is {0,0,1}, just above the surface at its center. What should appear is that the center the plane must appear bright (because it is close to the source just above the center and for geometric reasons), while the edges (distant parts) of the plane must appear dark. It does not happen

I've adjusted the properties of specularity and so on, never managed to get the bright region expected in the center.

bluetooth – Unable to get data attachments tags with the help of Google Nearby API on Android

I am a newcomer to tags and am having problems with the Message API near Google. I did it as shown on their page (https://developers.google.com/nearby/messages/android/get-beacon-messages) but it does not get any attachments of the tags.

It connects to the Google API client, it subscribes successfully but never gets to "onFound" or "onLost". I am able to successfully register the lighthouse and locate it in the "Tag Tools" application.

bluetooth – Nearby iPhone / Android file sharing systems on multiple platforms

In the past, I was excluded from group discussions, I was not allowed to join groups and I was generally discriminated against because I had an Android while almost all the people I know own an iPhone. I've been trying to find ways to integrate the features of the iPhone and Android to bring the two platforms closer together. I had found the "WeMessage" application that would allow an Android user to use iMessage, but I have not configured it yet. Then I wondered if there was a way to send and receive messages using the AirDrop feature of the iPhone on an Android. My phone, a Huawei Mate SE, has a feature called Huawei Share, but it only works with other Huawei phones. Does anyone know how AirDrop works or how to use a file-sharing system close to one platform at the other?

How can I stream audio to another nearby Android device?

I have tried the RTSP server over LAN, but the delay is too long. Is there a more efficient way to achieve this?
