Rigidbody appears to jitter when placed as a sibling to a First Person camera

In my game, the Player can pick up an object (which gets parented to the first-person camera), or the player can push an object (which is parented to the player, but not their first-person camera). Both mechanics use very similar implementations in regards to moving the objects, yet I get a pretty severe amount of ‘perceived’ jitter from Pushing — the object, as far as I can tell, isn’t actually jittering.

(Side note – wasn’t sure where to upload footage so I used mega which can be used merely to view the footage)

Footage of the lift for comparison

Footage of the push but parented to the first-person camera

Footage of push frame-by-frame from the side at 0.50 timescale

Footage of the lift frame-by-frame from the side at 0.50 timescale

The object is moved in FixedUpdate and the camera is moved in LateUpdate. You can see pretty clearly that in the side view, the camera moves after the object. Since the object is parented to the camera on Lift, it moves with it and no change is perceived. However on Push it doesn’t move and thus appears to jitter.

I’m not sure how to fix this. I have tried enabling interpolation on the rigidbody, the jitter occurs even if gravity is disabled and the object is lifted off the ground (e.g., not caused by collision with the floor), and I have tried the following code in LateUpdate to sort of nudge it forwards –

protected void CheckCameraPosition() {     if (m_LastCameraPosition == Vector3.zero)         return;      Vector3 newPosition = m_FPCamera.Transform.position;     if (newPosition == m_LastCameraPosition)         return;      Vector3 newOffset = newPosition - m_LastCameraPosition;     newOffset.y = 0f;     Transform.position += newOffset; } 

But the object still jitters and were I to seriously consider the above code I’d be worried about race conditions since the camera movement is executed in LateUpdate as well.

use recaptcha service on just first tier

sorry if the answer is already on here, but ive searched & did not find the answer, but how do you just select to use the recaptcha service (i.e. deathbycaptcha) on just the first (top) tier ?
ive looked in the “captcha” admin where you add the captcha service & there is nothing there.
i can only see it applies universally to everything.
i have gsa captcha breaker already – then first tier to go to deathbycaptcha
but i want lower tiers to be gsa captcha breaker only

When did Monks make their first appearance in D&D, and how do they differ between editions?

My curiosity continues after asking When did Rangers make their first appearance in D&D, and how do they differ between editions? Also, see about Druids and Artificers. This series of question is based on the initial question regarding Warlocks by aaron9eee:

A quality answer would have more than just a release date, and would ideally cover what makes each edition’s version different from other editions.

Iterative Depth First Search for cycle detection on directed graphs

I found this pseudocode on Wikipedia, and looks very elegant and intuitive:

L ← Empty list that will contain the sorted nodes while exists nodes without a permanent mark do     select an unmarked node n     visit(n)  function visit(node n)     if n has a permanent mark then         return     if n has a temporary mark then         stop   (not a DAG)      mark n with a temporary mark      for each node m with an edge from n to m do         visit(m)      remove temporary mark from n     mark n with a permanent mark     add n to head of L 

I am trying to write an iterative version for this using 3 marks (UNVISITED, VISITED, PROCESSED), but the lack of tail recursion really bothers me.

How should I approach this?

Finding sequence of pairs with second element of previous pair matching first element of next pair

I am interested in efficient ways of doing certain problem.

I have list of $ n$ pairs, where $ n$ is usually a few houndred thousands and each pair’s element is an integer (let’s assume it is integer from $ 0$ to $ 10000$ ) and I am trying to find a sequence such that it start and ends at chosen integer (we can assume it is eg. $ 0$ ) and second element of previous pair matches first element of next pair. So as an example, if we have set of pairs $ \{(0,1), (1,3), (3, 2) (3,0)\}$ the valid sequence would be eg. $ (0,1), (1,3), (3, 0)$ . If there is a few answers then I can find arbitrary one. Moreover it is no certain that my list of pairs actually has a solution. If it does not have solution, then the method should return no valid solutions.

I think that maybe some kind of dynamic programming could be useful here, but I don’t really have an idea for something better than just checking all the options, which I am almost certain is quite bad. Do you have any interesting insight about this problem?

Advice for first time DM/player with first time hero players trying the Lost Mine of Phandelver with an under-sized party

After listening to and enjoying some “actual play” podcasts I’m about to try DnD with my wife and children. None of us have played before, so after some research I’ve decided to go with the official DnD 5e starter set.

Due to a slight misunderstanding I thought that the set was fine for four players including the DM, it seems that actually it’s meant for a party of four or five plus the DM.

Given that the party will only be three strong, none of them have played before, and two of them are children I would expect them to not be hugely effective to begin with.

As DM I’m planning to help as much as I can with the rules and hints about what they can do (initially they won’t have read all the rules). But I’m concerned that as a small party they might struggle.

The kids have decided that they like the wizard and rogue and my wife is happy to play any of the remaining characters. From my research I’ve suggested the cleric for her so that they have someone with high AC and good healing.

As I haven’t played before either I’m looking for suggestions on what else I can do to get things off to a good start. Obviously I can do things like reduce the number of enemies in fights, but I assume that there are a lot of other tricks that I’m not aware of to help in this kind of situation.
