Custom-Libraries

This repo contains my custom libraries and links to some that I use.

These are for my personal use, but feel free to try them out as well.

Short descriptions.

Do note the parent-child relations of libraries. For example, CustomSDL requires CustomCPP and freetype.

• CustomSDL ` - has a UI class with some GUI elements. A surfaceManipulation class for quick surface editing and color retrieving.
  • CustomCPP - has a few conversion functions, windows-specific functions and a few algorithms.
  • Freetype.
• PyCLink - has functions to send data from a c++ application to python and vice-versa.

In detail.

• CustomSDL has:
  • a UI class. It uses freetype library to display a text field, has has a button class, a scrollBox class for textures and a list of buttons, a pane class for a simple background that 'blocks clicks'. UIFLAGS allow quite a bit of customizability.
  • a surfaceManipulation class. It is useful if you want to draw to a surface multiple times, as the class creates a surface with specified parameters and you can easily call a function to draw to a specific pixel.
  • Outside-class functions:
    • onRect function to check if cursor or given x,y coordinates are within an SDL_Rect's area.
    • compareRects, self explanatory, returns true if two SDL_Rects are equal and false if not.
    • getSurfaceColors returns RGBA colors of a given SDL_Surface's specificied pixel.
    • blitSurface more or less user-friendly explanation on what arguments to provide to an SDL_BlitSurface function to merge 2 SDL_Surfaces.
    • getWindowHandle function to get HWND to SDL created window.
• CustomCPP has:
  • a upsAverage function, which returns the number of updates in the last second.
  • A few conversion fuctions:
    1. intToString
    2. stringToInt
    3. doubleToString
    4. stringToDouble
    5. charToLPWSTR
  • Miscellaneous
    1. append_char_p - Append a character array (char*) to a given character array (char*).
  • Windows specific functions:
    1. browseFolder function opens a Browse for folder window to select a path to a folder on the system.
    2. getScreenPixels function returns a pointer array to color struct of the specified area's on the screen pixel color values.
    3. windowIgnoreColor function makes a window completely ignore a specified color, effectively making that area transparent.
  • Algorithms
    1. Mergesort.
• PyCLink:

  • It is not finished. direct_cpp-py_link is currently the latest version and can only exchange char* type info.

    In short how to use it (parameters explained in header/module files): Write a python script that calls receiveInput to receive input from c++ ( not required ). Before python closes, to send a string back, call send function. The C++ application shoud call communicate function to start the python executable and wait for it to close.
