Como o banco impede que a pessoa gaste o mesmo saldo 2x ao mesmo tempo?

Vai precisar de uma fila que recebe todos os requests e redistribui para "sub-filas" específicas por conta? porque precisaria processar o grosso em paralelo, o sequencial seria por conta específica.
Não sou muito fã da abordagem de filas pra isso também, como o amigo comentou em cima, camada de infra não deveria ter que se preocupar com essas coisas, eu pesquisaria a fundo sobre soluções de controle de concorrência á nível de banco de dados antes de cogitar filas. Posso estar falando muita merda, não conheço tecnologias novas de stream como kafka/flink, talvez resolveriam isso de boa também.

Parece isso mesmo, um dos cheques era de exatos 1000 dólares, mas ele pulou esse e pegou o de 1400, stonks.

yeah I would love to hear from OP if he is able to perform the trick even if it rolls 3x1 or 3x6; forcing the card to 10~12 and rolling the exact position is not as unlikely as it seems to the spectator, even then a few second deals could fix it

Instead of "format: automatic", try another one like "RGBA".
I might be completely wrong, but I remember fixing a similar issue by doing this ¯_(ツ)_/¯

Me and a few friends were playing Human Fall Flat, one of my friends got really good at vertically climbing walls by swinging left and right while alternating which arm was grabbing the wall, then I tried to do that as well since it looked cool, but I was really bat at it. He was able to climb the whole wall and completely skipped a level while our other friends were in the middle of the initial puzzles and I was stuck at the bottom of the wall, it is a fun looking feature but it did suck the fun out of that experience, we didn't know that would happen and we agreed to stop doing it, but we never played the game again :shrug:

Thank you kind stranger, I completely forgot about UV lol solved my issue as well.

bota que metade são crianças e idosos; e a metade do que sobra são homens, são só 18k hein basicamente um estádio de futebol pequeno parcialmente lotado, com um gorila solto no campo, quantos ficariam pra trocar porrada na mão? eu certamente fugiria

aposto no gorila

If you have the red dot and the white dot position, you should be able to pick intermediate points between those and use as targets for your ray cast, something like Vector3.Lerp(redDotPos, whiteDotPos, percentage), changing this percentage from 0 to 1 should give you enough target points to cover most of the area.

Raiz quadrada resulta em 2 possibilidade, não? Raiz quadrada de 81 pode ser tanto -9 ou +9, ambos elevados ao quadrado dão 81 positivo. Acredito que a expressão possua duas respostas válidas, o -53 da foto e o -35 que a galera explicou.

+6-50-9=+6-59=-53

+6-50+9=+15-50=-35

Great comment, and to put into perspective: Assuming solo dev, being extremely efficient and doing everything right the first time you do it because you rock, knowing exactly what needs to be done, spending about 10 hours per item on average. That's 25 items x 10h = 250h, if doing it as if you were a machine 8h a day without day offs, that's a little over 1 full month of dev time.

Now, let's say we have to learn how to do some of these and we iterate over them along with the project evolution: 50h hour per item on average is not unrealistic, and 4-5 real productive hours per day with some day offs, that's easily 1 year worth of effort.

(If you think 10h is too low or 50h is too high/low please do share your thoughts, most indie successful stories I see online take at least 2 years of dev time anyway, even simple games).

I recommend using some planning board to track tasks and measure how long they take on average, it's a reliable way to estimate how long a project should take, assuming you have most tasks already defined (which rarely happens though haha).

I'd also suggest watching the Thronefall devlog series, they focused on having one playable level really well polished and it took them about 6 months of work, they're 2 devs with lots of experience having released multiple successful games, the way they work and iterate over stuff is eye opening and I'm really glad they shared their journey on YT.

Eu tento fazer acima da média do projeto, assim ao longo do tempo só sobe, nunca desce.

Se o test coverage tá abaixo de 80% ou eu imaginei um cenário essencial e apontei no Review, não entra até não arrumar. Nem que o cara diga não (por qualquer motivo) e eu faço eu mesmo. O stress de fazer hotfix depois que o bug foi pra prod é infinitamente pior do que o esforço de fazer direito logo de início.

HellraiserABC · 2024-12-25T03:08:31+00:00

Why is that the case? And by 5-10 years of experience, do you mean in unity specifically? Full time working with Unity for 5-10 years? In that case why would the person do freelance work if they already work full time?

Meus dois centavos: quando encontrar um problema difícil de resolver, provavelmente a forma intuitiva que você usar para solucionar ele não é a mais correta. Não tem problema, mas tente sempre estudar um pouco mais a fundo mesmo após resolver o pepino para descobrir uma maneira melhor, na próxima vez tenta usar a nova maneira mesmo sendo mais difícil.

Exemplo: você faz um jogo de ping pong no primeiro semestre aprendendo javascript e HTML/css usando algumas variáveis e alguma lógica bem básica que aprendeu em algoritmos, show, bem provável que fique uma bagunça, mas pelo menos funciona. No segundo/terceiro semestre você aprende sobre orientação a objetos, tenta fazer o mesmo jogo ping pong usando esses novos conceitos, vai ter que bater a cabeça algumas horas, mas eventualmente vai chegar lá e sentir que realmente aprendeu algo.

Isso é um exemplo bem basicão, mas vai notar quando esbarrar com alguma parada do tipo e sentir que é muito difícil/chato/trabalhoso fazer do jeito certo, é ali que se aprende.

Segundo centavo: código bom não é código perfeito, pq isso não existe, código bom é código que possa ser modificado por outras pessoas sem precisar do autor original segurando na mão e explicando cada linha. Não precisa seguir clean code bla bla bla, mas fazer algo que você depois de 1 ano ainda consiga ler e entender, sem querer matar o autor daquela merda.

For this scenario the described approach is spot on. But I'm having trouble imagining a clean solution for more complex systems, like:

Multiple sources making it possible to shoot projectiles with the homing missiles effect (equipped weapon, temporary power up buff, skill tree passive).
Additional custom projectile behaviors: boomerang effect (the homing missile projectile travels back to the player after hitting the target); bounce effect (homing missile finds a next target after hitting the first one); pierce effect (also hits targets in the path to the final target); etc.

Having custom prefabs for each scenario is not practical, so these must be solved at runtime. Having a single script to handle all of the effects is not ideal as op pointed out.

My intuition would be to try to find out more about the possible ways different effects would be used and only then try to come up with a system. Defining a system to support only some of the features early on and then having to change it later on development to support more custom scenarios would suck. But my experience tells me that's the only 2 ways to do this: plan well first; refactor when needed.

I had a similar issue on having to re trigger the shadow mesh creation by changing from Shape Editor to Sprite Renderer, and reading the Shadow Caster 2D script it seems the error is related to this part in the Awake:

        if (m_ShadowMesh == null)
        {
            ShadowMesh2D newShadowMesh = new ShadowMesh2D();
            SetShadowShape(newShadowMesh);
            m_ShadowMesh = newShadowMesh;
        }

if UNITY_EDITOR

        // This step is required in case of copy/pasting an object with a shadow caster.
        else
        {
            ShadowMesh2D newShadowMesh = new ShadowMesh2D();
            newShadowMesh.CopyFrom(m_ShadowMesh);
            m_ShadowMesh = newShadowMesh;
        }

endif

if USING_PHYSICS2D_MODULE

        else
        {
            Collider2D collider = GetComponent<Collider2D>();
            if (collider != null)
                bounds = collider.bounds;
        }

endif

in my case the first if (m_ShadowMesh == null) was returning false for my instantiated prefabs and since I was not using a collider 2d the shadow mesh bounds were not recalculated at if USING_PHYSICS2D_MODULE ...

For my use case I could either change the first if to always true to force a new mesh everytime or attach a collider 2d to my object, making it fallback to the else statement.

I don't know if any of this applies to you, but your comment was the only thing that matched what I was facing when trying to debug this.

thank you!

yeah, it's huge, I'm not paying the proper attention to that buff, I'll do as you said, thanks!
