1. receivig operator overload errors on the [] operators. 2. I have tried to implement a function that'll cover it but I do not think I did it correctly because nothing new happened. 3. Got stuck, been looking for a solution since. 4. https://pastebin.com/Y90j7XPH

I don't think it's too difficult, although I probably am getting burnt out and could use fresh eyes

Welcome eh

- there is no ostream << operator overload for std::vector - std::priority_queue is not random access and does not implement operator [], you cannot use [] to access elements in a priority queue since this might invalidate the data structure

Pete

So I have to push/pop instead of access it like a typical array?

Pete

And because the print array << error is a vector I will not be able to overload the operator?

yes.

Anyone here familiar with c++ to web application compiling in an considerable easy way? looking for a way to expand our game to mobile and web

Jaimy de Vries

currently installing emsdk

Pete

yes.

Just from a quick overview of my code. I pretty much have to redo everything then correct?

Jaimy de Vries

anyone here knows more about it?

yes, you can overload the << operator, you're not doing it, hence an error

I don't get what you're trying to do. A priority_queue is basically a min/max-heap. Why would you perform another "heapify" operation on it? The data structure does not allow Random Access to prevent people from invalidating the heap. - If you need a max/min-heap use std::priority_queue - if you want to implement one yourself, use std::vector as backing data structure, it will grow and shrink if necessary and offers Random Access Additionally you pass many parameters as copies, modifying them without storing them inside the class or returning them is basically a noop (you won't be able to see the changes made)

I should hire you as a consultant Wish I heard that 3 days ago. I was a bit confused on the structure but I tried to implement heapsort best I could with the functions I’m supposed to use. it makes much more sense now explained that way. So I have to redo my program now I suppose

Hey Olli I have a quick question do you have a minute?

Jaimy de Vries

I dont mind to donate a bit for a solution ^^

Hey Olli I have a quick question do you have a minute?

#meta what's your question?

Jaimy de Vries

thanks Olli

so the issue im running into is trying to compile my source code to a source that can be loaded in web browsers

Jaimy de Vries

I heared a lot of good stuff about emSDK and tried it but I only figured how to compile 1 file and not an entire client at once. for example: emcc hello.c -s WASM=1 -o hello.html works but emcc dir -s WASM=1 -o hello.html or emcc /dir hello.c -s WASM=1 -o hello.html does not work

Jaimy de Vries

Any $x Developers? 😅

It probably depends on your build system / setup so far. Porting from a makefile or cmake based project should not be too hard. Never really used emcc though, this might help https://emscripten.org/docs/compiling/Building-Projects.html
