If you are still here, lemme give you a hint: draw a glow around them to create a different type of wallhack. It should be relatively easy and non-VAC detectable.
Why does everybody make a fuss out of certain type theories being undecidable, when all that really means is the type inference isn't complete? Even in a dependent type theory, you should still be able to infer the types of most functions.
void closeBinaryFileRead(BFILE* f)
//This function closes file f. Once it is closed, you cannot read from it again.
can i just reopen it and read from it again?

So the purpose of a string of questions I have is to try and do things without using functions that make it easier. (IE, mainly using for loops, if statements, etc. Nothing that automates the whole process. Just basic shit)
So I'm attempting to create a vector of random but unique integers.
Only logical way I can think to do this without using a randperm function of some sort is to just generate a random integer, add it to the vector, then check to make sure that nowhere else in the vector had that value.
Any more efficient algorithm, keeping in mind I basically have to do this as "barebones" as possible?
The actual end goal is just to create an anagram of a vector but once I can randomize the order, it's no trouble.

i dont access internal objects and classes directly, i just reverse engineer the memory layout of any structure im interested in (BaseEntity etc) and then use external api calls to read those structures from the target game into my own process, where i can use the information to draw and update stuff as needed

Like I can't just use "randperm" or something. Dig?
So yeah, the solution I was gonna use was generate a number, check if it has been genned yet, and if not, gen another one until getting a unique, and doing that until I have a vector of 10 unqiue integers in a loop.
>>51724326
>implicit types
The type it holds is on the other side of the equality. It's great if object has a long name, or could be one of multiple types (like a Collection, List, or Dictionary).
>overloaded operators
Done completely sanely, there's no confusion to what's happening. In fact, it's exactly the what operator overloading exists to do. Make mathematical operations on non primitves more elegant.
>contrived example with retarded setters
It's the only way to do setters in java. You can't use a public field if you need to do validation.

so I have been playing around, and looking at the lua stack
when I check the stack after I add my three entities, I just seeuserdata userdata userdata
when I check the stack after I try calling a function that should be in them (it gets them from a prototype), I seeuserdata userdata userdata table 'attempt to call a nil value' table 'attempt to call a nil value' table 'attempt to call a nil value'
this is how I learn m8, so it would be cool if any of you here tell me whats going on, here is the "relevant" codetypedef struct
{
int prototype;
boolean used;
} entity;
void loadEntityPrototype(lua_State *vm, int prototype, const char *path) {
if(luaL_dofile(vm, path)) {
printf(lua_tostring(vm, -1));
}
lua_pushnumber(vm, prototype);
lua_getglobal(vm, "prototype");
lua_settable(vm, LUA_REGISTRYINDEX);
}
void g_ENT_add ( int prototype )
{
int entity = highest_used_entity;
g_ENT[ entity ].prototype = prototype;
lua_pushlightuserdata(LS, g_ENT + entity);
lua_pushnumber(LS, prototype);
lua_gettable(LS, LUA_REGISTRYINDEX);
lua_pushstring(LS, "new");
lua_gettable(LS, -1);

My question is how do I show "correct answer" from my method? Whenever I type correct answer.show () obviously it doesn't work
>javashill still hasn't explained what he thinks elegance means and give and example of it
What would you call a class/struct that just holds a bunch of related stuff? Particularly, SDL's SDL_Renderer*, SDL_Window*, the KeyboardState, MouseState, etc etc. I want to put all of it in one spot, but I can't for the life of me come up with what it should be named.
in c++ with <string>, can i do
myString[spot] == '0'
to test if the character at spot is 0? or would i have to create a new string containing 0 beforehand and test it against that?
>>51724451
>lua_gettable(LS, -1);
Supposed to be -2, because the index "new" is on top of the stack (-1) and the table is just underneath it (-2).

Also c# has:
structs,
pointers,
reference parameters,
real generics,
generic primitives,
linq,
runtime dynamic types(not sure why you'd use them, personally, maybe for web dev)
Decimal types
datetime as a value type,
various null operators (null coalecing, null conditional)
The most useful one for elegance in my opinion is linq. It's the best way to work with complex datatypes or markup files.
Java 8 did introduce something like linq with streams but it's definitely not as elegantly implemented in my opinion.

with a method call you know that it could do something more than a simple binary operation. with an operator you know that it does not do anything more than a simple binary operation, if you don't have operator overloading.
how is having both add() and a "+" that could do anything more elegant than reserving "+" for "+" and having add() for other things?

var is static you idiot. Once it's assigned to a type it can't be reassigned to another. You can do that with dynamic, though I've never seen it used.
>if you ever see += in java code you will instantly know that it's either a primitive or a string. can't say the same about C#
What's your point? How is that superior? You still don't know what the type is. I'd rather look at bignum1 + bignum2 than bignum.add(bignum2). It's vastly easier to read. If it doesnt make sense to overload you don't have to.
>comparing constructors to setters
Idiot. What if I don't want to initialize all fields yet. That's literally the purpose of a setter.
>>51724635
I changed every instance of gettable tolua_gettable(LS, -2);, that's what you mean, right?

If you get the error atMoron you = RETARD();Then you will always end up changing Moron to the new type anyways, so why not just use var and have it change automatically? What's the advantage?
>>51724836
>I don't know what the "var" keyword does
>>51724896
I'm not him.
>>51724841
Okay, well, the Lua is fine. I'd first check to make sure that you're getting a non-nil value when calling the "new" function, then seeing if the registry lookup to get the entity's table is working. Because somewhere along the line the entity table is being turned into nil.
I'm beginning to regret spoonfeeding you. Just FYI. I really hope that you figure this out for yourself at some point because I'm getting kinda tired of debugging code that I can't even run myself.
>>51724887
if fuckoff() takes a parent type and var changes to a different sub type it won't give a compilation error.

>>51724970
>>51724982
no, if you have Tard tard = FUCKINGTARD();
and the return type of FUCKINGTARD changes to Moron (a different sub type) it will give a compile time error.
>>51725010
Except you'd just be turning it into "Moron" anyways. Using "var" saves you the trouble.
>>51725010
And why is that useful if the only thing you do with tard is pass it to a method that accepts a Moron?
>bet you can't do this with C#
>*solves problem that only Java has*
>see Java is superior
>>51725029
>>51725032
Tard and Moron could behave differently. if the distinction didn't matter you would have written Idiot tard = FUCKINGTARD(); in the first place.
>>51724790
>>51724912
someone posted it already, but I have some (minor) changes-- test object
prototype = {
new = function()
print("new entity")
return {
name = "Sample",
foo = 0
}
end,
update = function(self)
self.foo = self.foo + 10
print(self.foo)
end,
draw = function(self)
--todo: add drawing function
end,
}
it prints "new entity" when called, so perhaps the return {} is not working correctly. i'll play around with that some.
>spoonfeeding
You're not spoonfeeding me, spoonfeeding is where I ask for a finished product without going through the steps to get there.
You don't spoonfeed someone by telling them that their rgb parade needs to stretch out between the values 0-100, you teach them how to do it.
>>51725010
The method signature for fuckoff ispublic void fuckoff(Idiot id);
If var takes type Moron, the program will fail to compile at fuckoff(tard).
How is this hard to comprehend. It's literally exactly the same, c# just reads and writes more elegantly
>>51725052
Then why the fuck would you be changing the return type of FUCKINGTARD() if you didn't want it to be different?
>>51725065
>You're not spoonfeeding me, spoonfeeding is where I ask for a finished product without going through the steps to get there.
Oh, I'm not, am I? I believe I've pretty much gotten you through every hiccup you've had, you've made zero progress without my intervention.
>>51725052
>Tard and Moron could behave differently.
and? They'll behave properly where they are used. That's the whole point of polymorphism.
If you have a variable of type Dog and pass it to a function that accepts Mammal, and you are worried about it misbehaving because that function was only meant to work right with Cat, then you have bigger problems in your code.
>>51725073
no it won't fail if Idiot is a parent class of Moron. in java you would specify Tard because you don't want it to be a Moron, and if FUCKINGTARD changes to a Moron you will get an error if you have specified Tard, but not if you just wrote var or Idiot.

>>51725052
>Tard and Moron could behave differently.
How does the java way prevent this?
if you change
Moron tard = retard()
to
Idiot tard = retard()
and don't change FUCKOFF() to account for this, you're going to get the exact same behavioral error.
If there's any chance var could cause that problem(which is a sign your program is shit to begin with, quite frankly) you're welcome not to use it, and if for some stupid fucking reason FUCKOFF takes the parent class of moron and idiot, then you still have the fundemental problem, and you've got some fucking awful code. If your function takes a parent class, and could break depending on the child class it's given, that's indicative of shitty code, and is one of the reasons things like typeof() exist.

>>51725133
I can tell you've spent too much time with Java because you're OBJECTively wrong, yet refuse to admit it.
Your entire argument is based around

if i got anif(thing=blah){}
else if(fuckshitup){}
else(...){}
if something triggers the if, will it check the elseif condition? i want to be able to make the function recursive but i can't do that if i call fuckshitup when thing is blah because it'll mess it up

We're explaining to you why you are wrong. You're not even defending yourself, you're just getting really pissed when we explain stuff to you. I've been using Java and C# for 12 years now. This is pretty basic stuff.

encapsulation doesn't really do anything. if you really want to access something private you can.
If I see a variable or function name prefaces with an underscore I leave it alone because I know it won't do what I want it to

That's actually a non-issue because no one ever misuses existing public fields.
The best mechanism of encapsulation is the module. Prove me wrong.

>I know
Thank god everyone knows these conventions.
My real issues with prototypal is the extra cost of a table lookup and that people can fuck with parent classes and fuck up all the objects that inherit it. Class definitions are not something that should be dynamic, classes are an extension of types. How thinks a language runtime should be able to make new types or modify existing ones?

>>51725522
As far as I can tell, basically anything that doesn't involve constructing a proof.
Like the identity:id x = x
// x isn't constrained => polymorphic
id : a -> a
// elaborate normally
id : {a : Set} -> a -> a
or addition of naturals:m + Zero = m
m + Succ n = Succ (m + n)
// second parameter is destructed as Nat
// result is constructed as Nat
// m is used as result => m is also Nat
_+_ : Nat -> Nat -> Nat
This is a proof that addition has a left identity of zero.leftID Zero = Refl Zero
leftID (Succ m) = cong Succ (leftID m)
// parameter is destructed as Nat
// result type is some sort of equality, but equalities are dependent
// following annotation must be supplied
leftID : (m : Nat) -> Zero + m == m
>>51725755
try uploading everything no more than once or as rarely as possible (not every frame). use skeletal animations so the GPU will take care of animations

Because it's quite a large project, and performance doesn't really matter.
The dissector is only a small part of the network stack.
Writing in C or C++ would cost a lot more time, though for decoding protocols structs are much easier.
I would have used either Elixir or Scala, if either had support for raw sockets, without having to write a FFI myself.

for the huffman compression, it describes the huffman tree and then has the text with no break in between right? how do i tell the huffman tree function when to stop?
this is my function that reads the tree from binary// Function treeFromBinary returns the tree read in from the binary file at the second spot in the command line.
Node* treeFromBinary(BFILE* filename)
{
int x = readBit(filename);
if(x==1)

return leaf;
}
else if(x==0)

Node *left = treeFromBinary(filename);
Node *right = treeFromBinary(filename);
Node *nonleaf = new Node(left, right);
return nonleaf;
}
else
{
return NULL;
}
}
and these are my functions that read the actual text
// Function readCharCode reads a character code and writes the character to the output file.
// It returns false if it reached the end of the file and true otherwise.
bool readCharCode(Node* huffmanTree, BFILE* binaryFile, FILE* outputFile)

{
fprintf(outputFile, "%c", huffmanTree->ch);
return true;
}
else if(readBit(binaryFile)==1)
{

return false;
}
else
{

return false;
}
}
// Function uncompress uncompresses binaryFile into outputFile.
