I have trouble getting Cory's Collisiondetectionkit to work. I have installed it, and put the com folder in a random folder where I keep all my files. It looks like this:
but I get an error when I export the code below (along with a bit more code)
Call to a possibly undefined method checkCollisions
through a reference with static type Class
This is referring to the lines that says
if(CollisionLis...
below.
This is the code which I have imported it with:
import com.coreyoneil.collision.*;
and this is where I call it in the code:
if(oCharUse == true){
if(CollisionList.checkCollisions(b1, oChar) == true){
trace("collision")
}
The folder the com folder is located in looks like this:
You're using it wrong. The function will create an array of DisplayObjects that are colliding. For example, if b1 and oChar are colliding, trace(CollisionList.checkCollisions()[0].name); should trace b1 and trace(CollisionList.checkCollisions()[1].name); should trace oChar.
With what you're trying to achieve, you could replace
if(CollisionList.checkCollisions(b1, oChar) == true){
with
if(CollisionList.checkCollisions().indexOf(b1) && CollisionList.checkCollisions().indexOf(oChar)){

I have a map leaflet that I want to save in an html file in a specific folder.
I am using Windows 7.
I tried the following :
library(htmlwidgets)
saveWidget(map_leaflet, file="ressources/test.html")
library(htmlwidgets)
saveWidget(map_leaflet, file="ressources\\test.html")
library(htmlwidgets)
path_name <- file.path("ressources", "test.html", fsep="\\")
saveWidget(map_leaflet, file=path_name)
library(htmlwidgets)
path_name <- paste("ressources", "test.html", sep="/")
saveWidget(map_leaflet, file=path_name)
As an error message, depending on the Rstudio session, I either have
1) Error in setwd(dir) : cannot change working directory
2) Cannot find path
When I only save like this :
library(htmlwidgets)
saveWidget(map_leaflet, file="test.html")
It works perfectly.
Thank you in advance for your help.
Agreed.
here is a workaround:
f<-"ressources\\test.html"
saveWidget(map_leaflet,file.path(normalizePath(dirname(f)),basename(f)))
The issues appear to be that saveWidget does not work with relative pathnames and normalizePath does not work for paths to files that done exist yet.
I would call this a bug in saveWidget.
edit:
I have contribute what I think is an even better workaround to an existing open issue
I use the with_dir function in the withr package to do this. I also put it in a wrapper function:
save_leaflet <- function(plot, file, overwrite = FALSE){
# save the file if it doesn't already exist or if overwrite == TRUE
if( !file.exists(file) | overwrite ){
withr::with_dir(new = dirname(file),
code = htmlwidgets::saveWidget(plot,
file = basename(file)))
} else {
print("File already exists and 'overwrite' == FALSE. Nothing saved to file.")
}
}
Im using the TexturePacker implemented by LibGDX to load my sprites.
For some reason however, the files are not found and it gives me this exception:

This code is causing the error:
public static void main (String[] arg) {
LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();
config.width = 800;
config.height = 800;
deleteFiles();
processSprites();
new LwjglApplication(new OneRoom(), config);
}
public static void deleteFiles() {
File outputDir = new File("../android/assets/sprites/output");
File[] listFiles = outputDir.listFiles();
if (listFiles != null && listFiles.length > 0) {
for (File file : listFiles) {
file.delete();
}
}
}
public static void processSprites() {
TexturePacker.Settings settings = new TexturePacker.Settings();
//System.out.println(Gdx.files.internal("sprites/input/player.png").toString());
TexturePacker.process(settings, "sprites/input", "sprites/output", "pack"); // THIS LINE CAUSES THE ERROR
}
I also got the EXACT same code in another project and it works just fine. I haven't found any differences in the project properties yet.
Make sure the sprites actually exist in that directory.
Sounds patronising but I was having the same issue and for me I was being misled by my assets directory in my desktop project being a "Linked Folder" that was actually just a reference to the assets folder of my core project. So in eclipse the folder is there and looks like there should be no problem but looking through windows file explorer it was clear the files didn't actually exist at that location.
My fix was to change the input and output to step back and check the core directory instead of the desktop.
So instead of:
TexturePacker.process(settings, "sprites/input", "sprites/output", "pack");
The following would work:
TexturePacker.process(settings, "../core/sprites/input", "../core/sprites/output", "pack");
Now I don't know your exact setup but considering your code works in a different project I would wager that the other project has the assets actually stored in the desktop directory where as this one stores the images in the core directory.
I have a bunch (over 1000) HTML files with just simple text. It's just a combination of text within a <table>. It's an internal batch of documents, not for web production.
The job we have is to convert them into JPEG files using Photoshop and the old copy paste method. It's tedious.
Is there a way you would do this process to make it more efficient/easier/simple?
I thought about trying to convert the HTML into Excel and then mail merging it into Word to print as JGEG. But I can't find (and rightly so) anything to convert HTML to XLSX.
Thoughts? Or is this just a manual job?
Here's a little something I created to convert a single html file to jpeg. It's not pretty (to say the least), but it works fine with a table larger than my screen. Put it inside a windows forms project. You can add more checks and call this program in a loop, or refactor it to work on multiple html files.

You can load all files in one page and use this lib html2canvas to covert.
You can running in the background use nodejs with node-canvas or make it a desk app with node-webkit
In case anyone was looking for answer that works, I ended up using a program called Prince: https://www.princexml.com
It works amazingly, and just have to target the HTML with CSS or JS to make it match your output!
So I've tried to build a small utility to view the contents of a JSON file in an easy-to-understand manner (for non-tech people).
I have Googled far and wide, high and low, but every example that shows how to consume a JSON file in Flash Builder uses the HTTP service, pointing to a file on the web.
Here I am, sitting in front of my MacBook, wondering why I can't make this work. In the documentation I've found (sort of relating to this issue), they always show Windows examples, and they seem to work fine:
C://me/projects/json/my_json.json
Perhaps I'm completely missing the obvious, but is this possible on a Mac as well?
I've tried
file:///Users/me/projects/json/my_json.json
That doesn't work. I've tried some "resolve to path" syntax, but the HTTP service does not seem to allow for anything but file paths in quotes.
Would anyone be able to pint me in the right direction?
Use the File API. It's really easy, here's a quick code sample:
// Get a File reference, starting on the desktop.
// If you have a specific file you want to open you could do this:
// var file:File = File.desktopDirectory.resolvePath("myfile.json")
// Then skip directly to readFile()
var file:File = File.desktopDirectory;
// Add a listener for when the user selects a file
file.addEventListener(Event.SELECT, onSelect);
// Add a listener for when the user cancels selecting a file
file.addEventListener(Event.CANCEL, onCancel);
// This will restrict the file open dialog such that you
// can only open .json files
var filter:FileFilter = new FileFilter("JSON Files", "*.json");
// Open the file browse dialog
file.browseForOpen("Open a file", [filter]);
// Select event handler
private function onSelect(e:Event):void
{
// Remove listeners on e.currentTarget
// ...
// Cast to File
var selectedFile:File = e.currentTarget as File;
readFile(selectedFile);
}
private function onCancel(e:Event):void
{
// Remove listeners on e.currentTarget
// ...
}
private function readFile(file:File):void
{
// Read file
var fs:FileStream = new FileStream();
fs.open(selectedFile, FileMode.READ);
var contents:String = fs.readUTFBytes(selectedFile.size);
fs.close()
// Parse your JSON for display or whatever you need it for
parseJSON(contents);
}
You hinted at this in your post about examples being for Windows and you being on a Mac but I'll state it explicitly here: you should always use the File API because it is cross platform. This code will work equally well on Windows and Mac.
I need to bootstrap Drupal. I have a php-file with all my functions and in one of those functions, I need to use a Drupal function which is located in the bootstrap.inc file.
Structure of the server:(d) drupal (sd)includes (f)bootstrap.inc(d) scripts (sb)functions (f) functions.php
So I need to include in a self-written function the "variable_set" function, located in bootstrap.inc.
A little piece of the function my college wrote (I'm terribly sorry, but I don't know how to format php on the forum. If someone does, please let me know so I can edit this mess):
function readxml()
{
echo "<br/>READING...<br/>";
$file = './config.xml';
$xml = simplexml_load_file($file);
if($xml !== false)
{
foreach($xml->config->children() as $item){
$name = $item->getName(); // GETS CHILDREN UNDER 'CONFIG'
switch($name)
{
case 'website':
foreach($xml->config->website->children() as $kid){
$childname = $kid->getName();
switch($childname)
{
case 'theme':
if(inserttheme($kid)or die ('failed to insert theme<br/>')){
echo 'theme is installed.<br/>';}
break;
case 'slogan':
if(insertslogan($kid)or die('failed to insert slogan<br/>')){
echo 'slogan is installed.<br/>';}
break;
case 'sitename':
if(insertname($kid)or die('failed to insert name<br/>')){
echo 'website name is installed.<br/>';}
break;
}
}
break;
`
So, somewhere in the theme/slogan/name section, I have to call the variable_set function which is located in the bootstrap.inc file.
Somewhere I found this (again sorry for the non-formated text):
$drupal_directory = "/home/httpdocs/drupal"; // wherever Drupal is
$current_directory = getcwd();
chdir($drupal_directory);
require_once './includes/bootstrap.inc';
drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
chdir($current_dir);
return;
I included it both in my function.php as well as in my final php-file (where all the functions are called) but no result... What am I doing wrong?
That code you found looks about right, what is exactly is "no result", are you getting errors or nothing or...? Also, where did you put it exactly? (If it is not in a function, you need to remove the last line (return))
Also, the proper way to fix this would be to integrate your custom code as a Drupal module, then you don't have to worry about stuff like this: http://drupal.org/developing/modules
Or if it is a CLI script, expose it as a drush command: http://drupal.org/project/drush
Answer to the question, just include the file inside the Drupal folder!
