what is this program for?🙄😅

wanting to learn how to use openGL in C++

oh okie 👍

I think you should go with Vulkan. it’s a successor of opengl

Please no

But still how would i fix this

to render a triangle in vulkan it takes ~1k lines

but learning opengl 2.0 is useless ¯\_(ツ)_/¯

Ok

const char* vertex = readFile(vertexFile).c_str(); here you're assigning the pointer of the std::string that the function returned, but that object is then destroyed and accessing that memory is no longer guaranteed to have the string you wanted

Whats the best to use then?

Whats the best to use then?

why not use std::string instead of those char*'s?

glShaderSource needs a char*

glShaderSource needs a char*

give it the c_str of vertex and fragment

i'd assume it'd be smart enough that it knows it has to copy the char* you pass it

is it possible to keep a return in memory from a func

Yes

depends

use heap memory

is it possible to keep a return in memory from a func

if you put it in memory yeah. like std::string vertex = readFile(vertexFile); would copy the std::string object back into memory

use heap memory

or this ^

How would i then do this

I got to write the file reading bit

then trow the readed text into the constructor, then return the created Shader obj

http://this.is-a-professional-domain.com/7e3CaVF.png

std::string vertex = readFile(vertexFile); Shader shader (readFile(vertexPath).c_str(), readFile(fragmentPath).c_str());

like this?

not familiar with OpenGL, so idk

Pff

it's garbage when reaching the Shader constructor

I think you should go with Vulkan. it’s a successor of opengl

O.o

:(

@mmihov any tips

return Shader(vertexCode.c_str(), fragmentCode.c_str());

it isn't working?

No

why initialize a new std::string called vertexCode?

Becous the way i'm reading the file

that string contains the content of the file

well tbh your code doesn't make sense

so you want me to initializa a shader object, so then i can go and load a shader which in turn gives me a new shader object

It's a static method

So i can do Shader shader = Shader::loadShader(filepaths..);

I don’t recommend you combining these two types of shaders. but also separate them

there’s also geometry/tesselation, etc.

ah then it's ok

so you must make it so the constructor copies the two things you pass to it

otherwise you'll have lifetime issues

i'd assume it'd be smart enough that it knows it has to copy the char* you pass it

^

because remeber that you're passing pointers to characters

not strings

They are seperated

I try to fucking read 2 files but failing hard af

starting to hate C++

Lol it’s okay

starting to hate C++

well you wouldn't be having these issues, if you did it "the C++ way" and used std::string's

How would i do it then

just assigning would work as it does a copy

which is what you need here

example?

So i can do Shader shader = Shader::loadShader(filepaths..);

Cherno?

no

no

so make sure the constructor takes std::string's and have the member variables be std::string's too

How is thay c++ related

Dayum

i tryed

But

the entire variable is null then

Lol instant ban

Lol instant ban

obviously

Well I thought #ot at least. but yeah. we are not indian tech support.

the entire variable is null then

can you try printing vertexCode inside of loadShader, because i'm starting to doubt that part is working

tho it should be

What should I learn first STL or SDL?
