Ray casting with AutoIt

Recommended Posts

Hi.
 
Been very interested in game development and wanted to write my own Wolf 3D on AutoIt.
 
Here what i got for today:

Looks very cool! I'm curious to see how you want to implement textures with GDI+. ;)

Btw, long time ago Eukalyptus coded a prototype of 3D Wolfenstein with textures -> Prototype 3D Wolfenstein in AutoIt (video only)!

      This project has been discontinued!
       
      Here a small tool I wrote to update my Sysinternal tools collection without the need to download always the whole package or visiting the site to check for updates. I know that there are several tools available (also some tools written in AutoIt) but here another one for the collection. It was good exercise for me to code it.
       
       
        
       
       
      Some files from the live web site cannot be downloaded although they are visible!
       
      Here the download link of the source code only: AutoIt Sysinternal Tools Synchronizer v0.99.6 build 2020-09-23 beta.7z  (1557 downloads previously)
      -=> Requires AutoIt version 3.3.13.20 or higher / tested on Win8.1 real machine and some VMs: Win7 / Vista / Win10
       
      Compiled exe only: @MediaFire
       
      Just select the Sysinternal Tools folder or create one and press the synchronize button to download the selected items. Click on AutoIt label (near to left upper corner) to open menu.
       
      Special thanks to LarsJ, Melba23 and mesale0077 for their help. 
       
      I've still some ideas to implement which are more gimmick related, so it is not finished yet...
      If you want to add your language please check out #Region Language. Thanks. 
       
      Please report any bug or if you have any suggestions.
       
      The language of the tool tip from each of the executable in the left list view were automatically created using Google translator and weren't checked for correctness.

      Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
      Press ESC to get the coordinates of the marked region.
      If you have any improvements, please post it here.

      This is an update or derivative work of Beege 's Scrolling Line Graph UDF
      https://www.autoitscript.com/forum/topic/109599-scrolling-line-graph-udf
       
      I noticed a few issues for my use case with the UDF one being that adding a sample required updating the waveform
      High CPU usage went hand in hand with that requirement
      Another issue was just how long updating took to complete
      I've hopefully rectified that with this version
       
      There are a few changes (only 1 line per graph for instance)
      The addition of a function AddSample (uses graphics paths to speed up drawing samples on update) Gridlines are only generated once A sample finished line can be added UpdateGraph allows you to compress the discarded portion of the graph (it looks kinda cool but uses more CPU) Lower Cpu usage Uses real Control Ids - it is a label control underneath so you get click events and can display text when control is disabled Example (Waveform.au3)

      AutoIt Windows Screenshooter
      Key Features:
      takes easily a screenshot from any visible window capture any region of the desktop incl. freehand capturing capture GUI controls and GUI menus separately capture a marked area every x seconds for a duration of y seconds create a GIF animation from saved frames (Vista or higher os required) capture to AVI file (without audio!) takes a screenshot from web sites (available only on Win7+ os and when Aero is enabled) put images to clipboard to paste to other applications easily color picker save image in different formats and also to PDF! add timestamp to saved images simple image editing options: greyscale, b&w, invert, rotate +-90° send image to printer and default email client preview of captured screens incl. zoom option multi monitor support display pixel color under mouse ruler basic image editor (paint, highlight, ellipse, rectangle, text and some graphic FX) watermark captured image no 3rd party tools or DLLs used - pure AutoIt! fully portable - no installation is needed multi language feature (Eng, Ger, Tur, Fra and Rus only) drag'n'drop an image to the app for editing To do:
      capture content of scrollable window/control capture cascaded menus Due to DllCall("User32.dll", "int", "PrintWindow", "hwnd", $hWnd, "handle", $hMemDC, "int", 0) limitation some windows cannot be captured properly (GDI+, ProgDVB, etc.) but can take screenshots of hidden windows. One workaround is to use full screen capturing (F11/F12) or "Grab Screen" function! Or try double click with rmb on listview items (beta).

      Ctrl+z: undo
      Only available on Vista+ os: double click with rmb on list items to use alternative screenshot functionality (beta)!
      When 'Grab Screen' is clicked you can hold down the ctrl key to switch to 'grab controls' mode. Control under mouse will be framed red.
      ctrl + shift will take the screenshot of appropriate control. To capture GUI menus you can press rmb which simulates the lmb. When a menu is opened press shift additionally to capture it.
      Press and hold only the shift key to capture any region on the desktop using freehand capturing - release it so capture marked regions!
      Or just mark resize able area which you want to grab. Press CTRL key to grab marked area or right mouse button to capture the marked area every x seconds for a duration of y seconds.
