Export Maya curves to Illustrator

Do you have a laser cutter?

Are you good at 3D Modeling in Autodesk Maya?

If you answered yes, then Maya To SVG is the perfect tool for you!!

Maya To SVG

Maya To SVG is a simple script I made for Autodesk Maya that will let you export any curves into cuttable SVG format for a laser printer. Is is in major version 1 right now so it is not the prettiest, but it has an installer and is pretty much usable 100%. It looks something like this:

capture

To use it just select a curve and then put in your width, height of the board you will cut, choose your units, choose if you are going to fit to page or otherwise put a scale ratio, and press export. Whichever directory you choose will then contain an SVG file which you can open in Illustrator, or straight in your laser cutter software and cut it out on any material!

Installing

To make life simple, I created an installer for Maya To SVG which will put it straight onto your Maya shelf. All you have to do is download the corresponding installer for your OS here: https://github.com/Stasadance/MayaToSVG/releases/latest, No admin required! Then just run the exe or .app based on your OS and it should look like this:

capture

All you have to do is click install, and when its done it will say 100%! If you experience any problems, please leave a comment or DM me on twitter and I will help you ASAP 🙂




A* Pathfinding in HTML Canvas

My friend has been working on a new game called Panzer.io, and he reached out to me for the (best) solution for his AI. I instantly thought of the A* algorithm, a simple-to-adapt algorithm that will find the fastest path to a target while avoiding obstacles.

I made a simple HTML canvas app to show it off, check it out:

See the Pen PbKdzw by Stas Darevskiy (@stasadance) on CodePen.

Configuration

This version of the A* requires the game world to be square, but can easily be fixed by modifying the for loops in:

function findPath(world, pathStart, pathEnd)
{
  // shortcuts for speed
    var abs = Math.abs;
    var max = Math.max;
    var pow = Math.pow;
    var sqrt = Math.sqrt;

    // the world data are integers:
    // anything higher than this number is considered blocked
    // this is handy is you use numbered sprites, more than one
    // of which is walkable road, grass, mud, etc
    var maxWalkableTileNum = 0;

    // keep track of the world dimensions
    // Note that this A-star implementation expects the world array to be square: 
    // it must have equal height and width. If your game world is rectangular, 
    // just fill the array with dummy values to pad the empty space.
    var worldWidth = world[0].length;
    var worldHeight = world.length;
    var worldSize = worldWidth * worldHeight;

    // which heuristic should we use?
    // default: no diagonals (Manhattan)
    var distanceFunction = ManhattanDistance;
    var findNeighbours = function(){}; // empty

Modify the heuristic to match your application, in which your game may need the algorithm to speed up or make a more accurate path. You can change var distanceFunction = ManhattanDistance; to DiagonalDistance or EuclideanDistance, and var findNeighbours = function() {}; to var findNeighbours = DiagonalNeighbours; or var findNeighbours = DiagonalNeighboursFree; (allows the path to go in between obstacles diagonally).

Add fonts as a regular user in Windows

Recently one of my teachers asked me to create a program that will let standard users on his computers install fonts for their artistic needs. Sounds simple enough.. right? The OS at hand was Windows 7 Enterprise. I had an idea in mind to edit the registry or add a Windows policy that will let me do such a thing, so I created a batch script. The first thing I needed to do was get admin rights. Hmm….

Admin Access In DOS

Thanks to Eneerge @ https://sites.google.com/site/eneerge/scripts/batchgotadmin, I was able to implement a simple vbs script that will execute my whole batch script as an administrator. It looks something like this..

:RequestAdminElevation FilePath %* || goto:eof
setlocal ENABLEDELAYEDEXPANSION & set "_FilePath=%~1"
if NOT EXIST "!_FilePath!" (echo/Read RequestAdminElevation usage information)
set "_FN=_%~ns1" & echo/%TEMP%| findstr /C:"(" >nul && (echo/ERROR: %%TEMP%% path can not contain parenthesis &pause &endlocal &fc;: 2>nul & goto:eof)
set _FN=%_FN:(=%
set _vbspath="%temp:~%\%_FN:)=%.vbs" & set "_batpath=%temp:~%\%_FN:)=%.bat"
fltmc >nul 2>&1 || goto :_getElevation
(if exist %_vbspath% ( del %_vbspath% )) & (if exist %_batpath% ( del %_batpath% ))
endlocal & CD /D "%~dp1" & ver >nul & goto:eof
:_getElevation
echo/Requesting elevation...
echo/Set UAC = CreateObject^("Shell.Application"^) > %_vbspath% || (echo/&echo/Unable to create %_vbspath% & endlocal &md; 2>nul &goto:eof)
echo/UAC.ShellExecute "%_batpath%", "", "", "runas", 1 >> %_vbspath% & echo/wscript.Quit(1)>> %_vbspath%
echo/@%* > "%_batpath%" || (echo/&echo/Unable to create %_batpath% & endlocal &md; 2>nul &goto:eof)
echo/@if %%errorlevel%%==9009 (echo/^&echo/Admin user could not read the batch file. If running from a mapped drive or UNC path, check if Admin user can read it.)^&echo/^& @if %%errorlevel%% NEQ 0 pause >> "%_batpath%"
%_vbspath% && (echo/&echo/Failed to run VBscript %_vbspath% &endlocal &md; 2>nul & goto:eof)
echo/&echo/Elevation was requested on a new CMD window &endlocal &fc;: 2>nul & goto:eof

This huge script is put at the bottom or invoked using call and then putting call :RequestAdminElevation "%~dpfs0" %* || goto:eof anywhere before your admin-requiring code begins.

Giving Users group full control

To allow regular users (conveniently named Users in Windows) to add fonts, the Users group in Windows just has to own the fonts folder in everyway possible. I accomplished this with a set of commands that require admin:

attrib -r -s C:\Windows\Fonts 
takeown /f C:\Windows\Fonts /r /d n
cacls C:\Windows\Fonts /e /t /g Users:C
cacls C:\Windows\System32\FNTCACHE.DAT /e /t /g Users:C

But this alone was not enough. There was one more step. The registry itself “owns” the Fonts folder in Windows, so you have to give the Users group permissions there too. Batch alone cannot do this.

SetACL.exe

With the help of a tool called SetACL, I was able to add this line SetACL.exe -on "hklm\Software\Microsoft\Windows NT\CurrentVersion\Fonts" -ot reg -actn ace -ace "n:Users;p:full" to give the Users group full permissions over the registry key that handles Fonts. A reboot later.. and anyone could easily add their own awesome fonts!
