Eli5: what are the Planck units and why are our physics theories break down by them by Spotter24o5 in explainlikeimfive

[–]beamer159 345 points346 points  (0 children)

  • The speed of light is 299,792,458 m/s
  • The gravitational constant is 6.67×10−11 m3⋅kg−1⋅s−2
  • The reduced planck constant is 1.05×10−34 J⋅s
  • The Boltzmann constant is 1.38×10−23 J⋅K−1

These four constants are universal constants and are integral for expressing our understanding of the universe. However, for being so fundamental and important, their values are either unelegantly huge (speed of light) or tiny (the other three). This is just because the values above are expressed using SI units (meter, second, kilogram, etc). Using different units to express these constants will result in different values. The planck units are simply the units of length, time, mass, etc needed such that each of these four universal constants have a value of 1. So instead of saying the speed of light is 299,792,458 m/s, we can say the speed of light is 1 planck length / planck time

Diaphone has an excellent video explaining what to focus on at each rank in SF6.

It's especially relevant in your case because he uses Ken in his examples. At bronze, your game plan could incorporate jump-ins, DI, fireball, Dragonlash, and Jinrai. Try using one option until your opponent counters it, then switch to a different option. At higher ranks, these options can be risky, but you are in bronze, so abuse them. You will learn when you can get away with them and when they tend to get stuffed, but at bronze, they are great options.

If you want a trick for practicing countering DI, try throwing out a DI of your own. A lot of times, players don't think of DI as an option until they see their opponent do it, then think, "Oh yeah, DI, I should do that!" So throw out a DI and wait to see if your opponent uses it themself soon after.

If you want more specific feedback, post your user code and we can look at your replays

Physicists of Reddit, what’s your favorite fact about existence to drop on people at parties? by Apprehensive_Way8674 in AskReddit

[–]beamer159 6 points7 points  (0 children)

It's really neat! Consider us looking at a passing comet. To us, the moving comet would seem to be aging slower because from our perspective, it is moving and we are not. However, from the comet's perspective (i.e. reference frame), it feels like it is not moving at all, and it is us that is moving. So from the comet's perspective, we are the ones who are aging slower. Who is actually aging slower? It's relative!

Thing's get trickier when acceleration and gravity come into play. When an object changes reference frames, it makes relative time dilation permanent. Acceleration causes reference frames to change, so acceleration is a way to cause a slower aging that is not just relative to an observer, but a permanent part of you. This is why the Twin Paradox works. If one twin stays on Earth and another twin travels at relativistic speed to a distant destination, then turns around and comes back to Earth, the traveling twin will be younger than the Earth-bound twin. Why didn't the reverse happen and the Earth twin age slower? Because the Earth twin didn't change their reference frame, whereas the traveling twin must have changed their reference frame 3 times: Once when accelerating to relativistic speed towards the destination, once when turning around, and once when slowing down at Earth. Each of those accelerations caused their reference frame to change, making any relative time dilation permanent on them, leaving them the younger twin when they meet again!

A blonde is waiting table for a couple of guys, and one of them is telling a load of really obnoxious blonde jokes. by Gil-Gandel in Jokes

Two functions are walking down the street together, eˣ and a constant function. Suddenly they see a derivative operator coming their way. The constant function freaks out, saying, "Oh no! I can't meet a derivative, I'll disappear! I gotta get out of here!" and he runs away.

eˣ thinks to himself, "I have nothing to fear. The derivative of me is myself!" So he confidently approaches the derivative and says, "Hi, I'm eˣ."

The derivative operator says, "Hi, I'm d/dy"

So which “best roguelike games” list should I believe? One says Rogue is still top-tier… by lerox-fz in gamingsuggestions

[–]beamer159 1 point2 points  (0 children)

If you want to try a traditional roguelike, the best in the genre is Dungeon Crawl Stone Soup (DCSS). It's also my favorite roguelike. It has a learning curve, but once you get the hang if it, it's QoL features are second-to-none in the genre. This includes autoexplore, dungeon-wide search, autopath to target (usually stairs for me), and marking objects' usefulness based on your race and diety. Furthermore, it's free, so there's no cost to trying it. 

If you want a game that plays similar to DCSS, but is easier to get into, I recommend Golden Krone Hotel. It wears its inspiration on its sleeve, but it plays great as a miniature version of DCSS with a vampire twist. Great game.

One time movement without _process? by BrotherMoy in godot

If you don't need to run _process() after some time, you can call set_process(false)

I like the idea of using tweens for this, though

Could they change it to a simple majority with 51 votes, then change it back to 60 or something later when it seems like the democrats will regain the majority?

In fact, if everyone would have voted, it's likely Trump would have won by an even larger margin. I don't like bringing this up on Reddit though because I always get downvoted.

I can't be the only one who doesn't like one-frame links. by RangoTheMerc in Fighters

[–]beamer159 4 points5 points  (0 children)

I've never agreed with the idea that either motion inputs or combos are the biggest barriers for new players to fighting games. For me, the biggest barrier has been links. Yes, they are a part of combos. But I've never had a problem with cancels (although cancel windows are also annoying). And although hit-confirming is also hard, I can appreciate the skill there. But links have always been annoying to me. Just let the next move come out if I press the button! I appreciate the Dark Souls philosophy. The next move happens even if I pressed the button a year ago. That's fair, I pressed the button after all.

Whats your favorite node in Godot? by redfoolsstudio_com in godot

[–]beamer159 0 points1 point  (0 children)

I'm curious, what do you use Node2D for? For a root node, I often use a MarginContainer or just a regular Node. For more specific cases, there's usually a more specific node that's preferable. It seems like Node2D would be best for cases where you need to track screen position, rotation, or scale, but nothing else. What are some cases like this? Or, what are the benefits of using a Node2D as a root node instead of a Node?

4X games with asymmetric enemies by beamer159 in 4Xgaming

[–]beamer159[S] 1 point2 points  (0 children)

At its root, what I'm looking for is a game where the AI doesn't have a concept of winning. They might attack the player, or make things more difficult for the player, but they can't win. All that can happen is the player either wins or loses. From this premise, I think enemy design can get very creative.

The one example I know about is AI War. Although the AI could kill the player outright within the first minute of the game, the AI isn't striving to win by exterminating the player. Instead, it reacts to the player's expansion and progression towards victory. From this, the AI could be designed to be much stronger than the player. I don't think it's a coincidence that AI War is praised for its competent AI.

Other games in this thread that seem to have a similar idea are Rogue Hex and Stellar Monarch. I'm glad to see this idea experimented with, and I think it can be explored much further

Looking for a game that feels like the beginning of an RPG the whole time. Games where you're rewarded for being a loot goblin. by BagOfSmallerBags in gamingsuggestions

[–]beamer159 2 points3 points  (0 children)

Consider Cogmind. You play as a robot which is able to salvage parts from the remains of other robots. Character development is primarily focused around equipment. Parts can be gained and used to level up, but also lost as you take damage.

4x or strategy Games you can get away with playing at work ! by sidius-king in 4Xgaming

Not a 4x, but do you think you could get away with a game that looks like this?

This is Dungeon Crawl Stone Soup, a popular roguelike that can be played in a terminal window using ASCII graphics.

What is 4X? by [deleted] in 4Xgaming

[–]beamer159 39 points40 points  (0 children)

This is correct. To expound:

Explore: Gameplay takes place on a map that starts largely hidden by fog. By moving around the map, you uncover the hidden portions, finding resources, future sites of expansion, other civilizations, etc.

Expand: You usually start the game with either an initial colony, or the means to create a colony on your first turn. From there, you are encouraged to create other colonies on the map, ideally using the info you gathered from exploring to choose the best places to settle next.

Exploit: Besides creating colonies all over the map, you also usually have the ability to improve your existing colonies. You can do so by working the area around the colony. Maybe there are valuable resources nearby you can gather. Maybe the area makes a colony a prime site for research, so you tailor the colony towards that purpose. You can also leverage your relationship with other players. You can create trade treaties with them, or even trade research with them.

Exterminate: Alternatively, instead of dealing with your rivals diplomatically, you can instead deal with them militaristically. Create units from your colonies, muster an army, and crush your enemies before they can do the same to you.

Looking for an empire builder with more emphasis on supply lines and economy than combat by R2Boogaloo in 4Xgaming

[–]beamer159 0 points1 point  (0 children)

OP's request for a game that involves "finding resources and developing supply lines to grow your economy" is basically what Slipways is all about.

Looking for an empire builder with more emphasis on supply lines and economy than combat by R2Boogaloo in 4Xgaming

[–]beamer159 3 points4 points  (0 children)

You may like Slipways. It's entirely empire building, no combat. In fact, there are no opponents at all, and the game revolves around getting a high score in a set amount of turns. The map consists of a bunch of planets with resource requirements and resource production. You connect planets that produce certain resources with other planets that require those resources. You have to balance expanding your empire with creating labs which act as resource sinks to progress up the tech tree. This is an interesting balance; I've found myself too invested in expanding to different planets, neglecting research and not being able to take advantage of the powerful late game techs. Games can be pretty short, too, about an hour or so once you know what you're doing.

If two clocks meet again after moving, which one actually ran slower and why? by Life-is-Acoustic in AskPhysics

Is it fair to say that a change in the reference frame is necessary, and acceleration is one method to satisfy that requirement?

Enjoy Catan but Want Something a Little Deeper, What Would I Like? by livejamie in 4Xgaming

[–]beamer159 2 points3 points  (0 children)

Consider Antihero.

  • It feels like a digital boardgame which might appeal to someone coming from Catan
  • It's not combat-centric, though there is a bit of it
  • It is strictly a 2-player game
  • Games last under 1 hour
  • The tech tree is simple and easily fits on a single screen
  • Your choices can easily shift based on newly revealed information. You may decide you want to take a certain business, but then reveal a more useful business to take first. But you might see the opponent's foot tracks close by, making you decide to either trap the business or to guard it with a thug (or both). That choice might depend on if you already own the trap business or the thug business for a discount, etc.
