font_and_text

bool font_init() {
	const char* font_path = PATH_FONT;
	TTF_Init();
	Font = TTF_OpenFont(font_path, FONT_SIZE);
	if (Font == 0) {
		return 0;
	} else {
		Font_color.r = 255;
		Font_color.g = 255;
		Font_color.b = 255;
		Font_color.a = 255;
		return 1;
	}
}

This initiates the font using a predefined font inside /resources/fonts/.
@return: FALSE if failed, otherwise TRUE

void print_text_to_screen_with_color(const char* string, int x, int y, SDL_Renderer* renderer, SDL_Color color) {
	Font_surface = TTF_RenderText_Solid_Wrapped(Font, string, 0, color, 0);

	Font_texture = SDL_CreateTextureFromSurface(renderer, Font_surface);

	Font_rect.x = x;
	Font_rect.y = y;
	Font_rect.h = Font_surface->h;
	Font_rect.w = Font_surface->w;

	SDL_RenderTexture(renderer, Font_texture, NULL, &Font_rect);
	SDL_DestroySurface(Font_surface);
	SDL_DestroyTexture(Font_texture);
}

This puts a string on the screen inside the provided renderer with color.
@param string: text to be displayed
@param x: coordinate on X-axis
@param y: coordinate on Y-axis
@param renderer: active renderer
@param color: SDL color to be applied to the text

Usage:

print_text_to_screen_with_color("ballin\0", 50, 50, &renderer, some_sdl_color);

void kill_font() {
    TTF_CloseFont(Font);
}

This properly ends font usage.

Usage:

/**
 * This SHOULD be called before ending the program
*/
kill_font();
