  • Sliding Response after a Point-Square Collision

    - by mars
    In general terms and pseudo-code, what would be the best way to have a collision response of sliding along a wall if the wall is actually just a part of an entire square that a point is colliding into? The collision test method used is a test to see if the point lies in the square. Should I divide the square into four lines and just calculate the shortest distance to the line and then move the point back that distance?If so, then how can I determine which edge of the square the point is closest to after collision?

  • Python ftplib - any way to shut it up?

    - by JamieH
    I am writing a test harness in python and as part of the testing I need to initialise an FTP server and upload various files. I am using ftplib and everything is working ok. The only problem I have is that I am seeing loads of FTP text appearing in the console window intermixed with my test results, which makes scanning the results quite tricky. I haven't found a way to shut ftp lib up and stop this happening, does anyone know how to stop this?

  • hexdump confusion

    - by zedoo
    I am playing with the unix hexdump utility. My input file is UTF-8 encoded, containing a single character ñ, which is C3 B1 in hexadecimal UTF-8. hexdump test.txt 0000000 b1c3 0000002 Huh? This shows B1 C3 - the inverse of what I expected! Can someone explain? For getting the expected output I do: hexdump -C test.txt 00000000 c3 b1 |..| 00000002 I was thinking I understand encoding systems..

  • What does the C# compiler mean when it prints "an explicit conversion exists"?

    - by Wim Coenen
    If I make an empty test class: public class Foo { } And I try to compile code with this statement: Foo foo = "test"; Then I get this error as expected: Cannot implicitly convert type 'string' to 'ConsoleApplication1.Foo' However, if I change the declaration of Foo from class to interface, the error changes to this (emphasis mine): Cannot implicitly convert type 'string' to 'ConsoleApplication1.Foo'. An explicit conversion exists (are you missing a cast?) What is this "explicit conversion" which is supposed to exist?

  • MySQL query being performed when PHP if condition not met?

    - by Ryan
    The script I'm using is if($profile['username'] == $user['username']) { $db->query("UPDATE users SET newcomments = 0 WHERE username = '$user[username]'"); echo "This is a test"; } (Note that $db-query is exactly the same as mysql_query) For some very odd reason, the MySQL query is being performed even if the defined condition is false The "This is a test" works properly and only appears when the condition is met, but the MySQL query is performed anyway Whats the problem with it?

  • Changing an Action Type="click" to an auto action in SVG

    - by Dustin Myers
    I have a SVG document that I exported from Visio 2003 that would like to edit. This file has an action where you click a button it will navigate to a new screen. What I would like to do is have the navigation be based off of a data point rather than having to click the button. As an example I have a dynamic point data being brought into the SVG file and when that value changes from 0 to 1, I want this screen to automatically navigate to another screen. Below is the code I for clicking the button. <title content="structured text">Sheet.1107</title> <desc content="structured text">Button 1</desc> <v:custProps> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(Test Graphic 2)" v:type="0" v:prompt="" v:nameU="ObjRef" v:sortKey="" v:lbl="" v:format=""/> <v:cp v:ask="false" v:langID="1033" v:invis="false" v:cal="0" v:val="VT4(SF-S)" v:type="0" v:prompt="" v:nameU="DataPt" v:sortKey="" v:lbl="" v:format=""/> </v:custProps> <v:userDefs> <v:ud v:prompt="" v:nameU="NAVIGATE" v:val="VT4(NAVIGATE Test Graphic 2,&apos;&apos;,)"/> </v:userDefs> <v:textBlock v:margins="rect(4,4,4,4)"/> <v:textRect width="125.01" height="35" cx="62.5" cy="517.5"/> <rect x="0" width="125" y="500" height="35" class="st3"/> <text x="40.15" y="521.1" v:langID="1033" class="st4"><v:paragraph v:horizAlign="1"/><v:tabList/>Button 1</text> <jci:action type="click" count="1">if(evt.button == 0) nav(&apos;Test Graphic 2&apos;,&apos;&apos;,&apos;&apos;);</jci:action></g></a> In the above code I am bringing in the data value from SF-S. Once that value is equal to 1 I want this screen to automatically navigate to Test Graphic 2. I don't have any experience with coding so I am hoping someone here will be able to help me. Thanks, DMyers
