I am working with SDL3 and I am encountering an issue with rendering textures. I am able to create the textures, but they don't show up on the screen when I try to render them.

Here's what I'm trying to do:

I am creating two surfaces, converting them into textures, and trying to render one of them after applying a rotation.

The surface creation and texture creation seem to be working fine, but when I try to render the texture, it doesn't appear on the screen.

I have tried:

Ensuring that the renderer is set to clear the screen before rendering new textures.

Using SDL_RenderCopyEx for rotating the texture, but no matter what, it doesn't render.

Debugging the issue by checking for errors after each step (e.g., SDL_CreateTextureFromSurface), but everything seems fine.

Here’s my code:

#include <iostream>
#include <cmath>

    if (SDL_Init(SDL_INIT_VIDEO) < 0) {

        cerr << "SDL_Init failed: " << SDL_GetError() << endl;

    }

        return 1;
    }

Problem: The textures are created successfully, but they don’t render to the screen when I try to draw them. I’ve confirmed the creation of the textures and the renderer, but still, the screen stays blank after I attempt to render.

I’m not sure where I’m going wrong. Does anyone have experience with rendering SDL textures? Could you suggest anything that might fix the issue?
