Calculate if jump is possible

Hey, I'm working on a 2D grid game (think Terraria), I want to check if a monster can make jump from point A (start) to B (target). It can adjust its horizontal/vertical speed to hit smaller/bigger jumps, same as the player can (for example by holding space for longer to jump higher). So I'm calling this function CanMakeJump(monster.gridPos, target.gridPos, maxJumpPower, someGravityValue) I have no clue if my formula is even right, I'm getting weird results partially because I don't know how to incorporate horizontal velocity which should be based on monster's movementSpeed statistic.

Benchmarking code

Hey, so I made myself a simple template for advent of code. Here is the code: https://pastebin.com/Z0dXuPNR I have 3 questions: - benchmarking takes quite some time. Around one minute I would say. Is this the expected time? I've never used this benchmark lib so I can't tell. - I want to separate loading the input / parsing the input / solving into 3 benchmarks cuz I want to see what takes the most time, how can I do this? - Is my template even okayish?

❔ Unity Zenject qustion

Hey, I have a question about Zenject. So I have a class

public class Test
{
  public Something _Smth;
  public Foo _Foo;
  private int Id;

  public Test(Somethnig smth, Foo foo)
  {
    _Smth = smth;
    _Foo = foo;
  }
}

public class Test
{
  public Something _Smth;
  public Foo _Foo;
  private int Id;

  public Test(Somethnig smth, Foo foo)
  {
    _Smth = smth;
    _Foo = foo;
  }
}

and I install it like this

 Container.RegisterNewInstance<Foo>();
 Container.RegisterNewInstance<Something>();

 Container.RegisterNewInstance<Foo>();
 Container.RegisterNewInstance<Something>();

then I have a list List<Test> Tests What I want to do is somehow make a for-loop that will create and add Test to Tests list. I want to make sure that _Smth and _Foo are installed using Zenject and I want to pass Id when I create this object. From my understanding of zenject if i do var test = new Test() it wont work cuz Something and Foo wont be installed right?

❔ LLVM problem with creating number

var res = VisitNumber(ctx, new("10")).Item2; for some reason the result is {i0 0} Any ideas why?

❔ Zenject (Unity) doesn't fire when i do new()

Hey, I have a class which looks like this

public class Something

    _a = a;

❔ LLVMSharp create signed and unsigned constants.

Hey, I'm trying to create a constant using this function

LLVMValueRef.CreateConstIntOfString(LLVMTypeRef.Int64, "195894", 10);

LLVMValueRef.CreateConstIntOfString(LLVMTypeRef.Int64, "195894", 10);

How can I specify the LLVMTypeRef to be signed or unsigned? Should I use a different function?

❔ LLVMSharp weird function

Hey, so I'm trynig to convert my class into a LLVM const. I have a class callled NumberAST:

class NumberAST
{
  public NumberType type = NumberType.Int64;
  public string value = "100000";
}

class NumberAST
{
  public NumberType type = NumberType.Int64;
  public string value = "100000";
}

And I was wondering how to convert it into llvm const. I found this thingy LLVMValueRef.CreateConstIntOfString() but I can't find it in the docs so i'm not sure how to use it

❔ Switch case on Int type

Hey, so I have a class with variable _type and I want to store a variable type in it (long, int, short, ubyte etc etc). Later I want to do a switch on _type something like

switch(_type)
{
  case long:
  case int:
}

switch(_type)
{
  case long:
  case int:
}

How can I do this?

❔ Pass variable type as class parameter

Hey, so basically I have a class

class Number
{
  public string Type;
  public string Value;

  public Number(string type, string value)
  {
    Type = type;
    Value = value;
  }
}

class Number
{
  public string Type;
  public string Value;

  public Number(string type, string value)
  {
    Type = type;
    Value = value;
  }
}

What I want to do is if I do this for example

var num = new Number("long", "10000");

var num = new Number("long", "10000");

Number.Type shouldnt be string but rather a long; and Number.Value should contain the value

❔ Maximum path sum in matrix

Given a M x N grid filled with some values I need to find a path from a target node which maximizes the sum of all values along its path. I can move in any direction. How can I do this? I've found some solutions online but they all go only from the top row to the bottom row when I need to go in all directions from any node.
