Hey, I was having some issues with the vector and the forloop using the emplace_back "C2661: no overloaded function takes 2 arguments"

I'm not sure why it was not allowing me to use this on the vector but what i ended up doing is using the push_back function:

-(below std::vector<SDL_Point> v BUT outside the forloop) SDL_Point temp;
- (Inside for loop) temp.x = rand() % 640;
- (right below that line) temp.y = rand() % 480;
- (right below that line) v.push_back(temp);

Not sure why i got that message but i got the same result using push_back

Tried using SDL2 in VSCodium on Arch but always got the error : "main.cpp:(.text+0x2d): undefined reference to `SDL_Init' ". Any idea what this could be? Thanks a lot.

Is it possible to set the renderer to be transparent?

Thanks a bunch, been having such a headache learning how to use this library, as graphics.h does not work on wayland. Saved me so much time.

Hello, when I run my programs, the window is not moveable, and I can not close the window using the window itself, I instead have to close the CMD window. Is there a fix to this?

I love your tutorials but the hardest part of following them is to get sdl2 installed, I'm getting bald with the ammout of errors and videos that work but not whey I try, I wish youn made a compehensive video about installing dependencis for c++ usage

This is the 2nd tutorial of yours that I've ALMOST completed.This tutorial and the spinning cube in SDL2 works great up until I use the emplace_back function and then it breaks. Ive commented out the "v.emplace_back(rand() % 640, rand() % 480);" and it compiles fine.
Any Idea?
