Questions About Alice Features

How perform I install Alice 2.x?

Alice 2 does not require installing.

For Windows machines:

Downfill the correct variation (Alice2.x.zip or Alice 2.xb.zip) of Alice to your machine.Unzip the file and copy the contents the whole Alice 2.x catalog which includes the “Required” folder, Alice.exe and SlowAndSteadyAlice.exe) to your computer. (Note: Windows now enables customers to open up a zip file favor a consistent folder, however Alice will certainly not execute without unzipping.)Copy the documents to another location on your computer (Desktop, Program Files, or the Documents folder).

For Apple OS X machines:

Downfill the appropriate variation (Alice2.x.dmg or Alice 2.xb.dmg) of Alice to your machine.Open the .dmg file and movethe Alice package to your computer. You might start Alice from inside the .dmg file, yet not all attributes of Alice will certainly execute effectively.Copy the papers to one more area on your computer (Desktop, Applications, or the Documents folder).

How perform I run Alice 2.x?

For Windows machines:

Double click on Alice.exe or SlowAndSteadyAlice.exe to run the regimen. The “Required” folder must be in the very same folder as the executables (Alice.exe or SlowAndSteadyAlice.exe).


For Apple OS X machines:

Double click the Alice package iconto run the program.


How execute I produce a shortcut for Alice 2.x?

For Windows machines:

You deserve to produce a shortreduced, but make sure the shortreduced is setup appropriately such that the regimen runs from the Alice 2.x folder.Do not copy the Alice.exe file and also run this file from another place.The executables (Alice.exe or SlowAndSteadyAlice.exe) have to be in the very same folder as the “Required” folder.

For Apple OS X machines:

You can create a shortreduced, by dragging the Alice package icon to the Dock, or by -clicking or right-clicking on the Alice package icon, and also choosing Make Alias... from the conmessage food selection.The new alias might be moved to your desktop computer or to various other areas on your computer system.

Alice will not begin on my computer?

Tright here can be many type of reasons why Alice will not run on your computer system, and it may not be led to by the regimen. Here is a list of factors and solution to the difficulty.

Graphic device without a appropriate motorists.

If your computer system provides a generic video driver, we imply that you obtain the correct video driver from the manufacturer.Generic video motorists are known to reason Alice to not start up.One such problem is brought about by video cards from NVIDIA.

Inenough permission (No review and create permission)

Alice creates a .alice2 folder in the user brochure to store all crucial files and also folders (i.e. Alice choices file)Alice might not run if such place cannot be developed or written to.Alice likewise calls for a read permission to the “Required” folder and all its contents.If network administrator prefer that all information be stored at an alternative location, you can modify the ..Alice 2.3Requiredetcconfig.txt file to include the course.In the config.txt file, you have to see something that looks like this:


Add a brand-new line at the bottomGo into in the *full* route to wbelow you would choose the choices stored. This will certainly must be a writable directory.Do not use quotes. For instance, to readjust the area to the desktop computer on drive E, perform the following:


E:Documents and also Settings\Desktop

Running a 32little application from a 64little computer system.

Some customers were able to resolve the difficulty by placing the Alice 2.x folder in their C:Program Files (x86) Another method is by changing the properties of the Alice executable (Alice.exe or SlowAndSteadyAlice.exe), to run in compatibility mode for Windows XP


Why am I obtaining the ClassCastException?

This is a known Java problem and tbelow is currently no solution to this problem. This is even more of a warning than an error. This will not reason a problem once running Alice 2.x. This trouble have to be ignored.


Alice a2w file cannot be opened up. How to deal with it?

We will usage the default.a2w file uncovered in your Alice 2.xRequiredetc folder to display you just how to fix the trouble.


This is what you will see when Alice stops working to pack the civilization. Notice in this instance, Alice is not able to uncover the light/elementData.xml.


You will certainly should open up the file making use of any zip routine (7-Zip, WinZip, and so on.). In the file, you will certainly see some folders, files, and the elementDocuments.xml in the main directory.


Open the elementData.xml file with any message editor (Notepad, WordPad, and so on.). Here, you will certainly see showing you all the items in your Alice people.


Due to the fact that we are missing the light/elementFile.xml, the best way to solve this trouble is to remove all references to the item (i.e. )from this file (because we do not recognize what the elementFile.xml in the light folder looks prefer and also cannot rearea the absent file).

Note: You might need to extract the elementFile.xml file from the a2w file prior to you can make changes to the file. Once you have made the changes, you have the right to relocate the file ago into your a2w file.

When you open up the a2w file, you will certainly obtain the complying with warning.


Alice is letting you know that you are lacking the light object and all referrals to this object must be collection to None. Click on the Yes switch. You have the right to now add all the missing items, correct the code as necessary and proceed via your programming.

Note: If you are still acquiring the error, repeat the measures over till all referrals to the absent items has actually been removed from the elementFile.xml file. In this example, tbelow are only 2 referrals to the light object.

When I run Alice, I acquire this error:

*sys-package-mgr*: can not produce package cache dir,"./jython-2.1/cachedir/packages"java.lang.ExceptionInInitializerError

followed by many kind of Java errors.

Make sure the user running Alice has actually compose permission to each file anddirectory unpacked from the distribution gzip file. In certain, the userwill certainly need create permission to the "Required/jython-2.1" brochure. If thingsare running effectively, Alice need to instantly produce a "cachedir"directory tright here the initially time it runs.

I cannot find the HeBuilder/SheBuilder that was in the People Gallery.

A choice was added to the latest variation of Alice, permitting customers to enable / disable the HeBuilder / SheBuilder application in Alice 2, to attend to the modesty pertains to of some of our users.

You will findin thispreference setting in the Edit food selection, Precommendations (F8) under the Seldom Used tab an choice to “present he/she builder in the gallery”. Click on this choice and you will have the ability to enable or disable this application.

See the complying with picture.


How do I print in Alice 2.x?

From the Data menu in Alce 2.x, pick the Export Code for Printing command also.Note: This instance is printing the code to the Alice instance world, LakeSkater (found in the Examples section of Alice 2.x)

Why an Alice Suite -- Alice 2.x and Alice 3.x?

When the breakthrough of Alice 3 was initially begun, our thoughts were that Alice 3 would be a replacement for Alice 2. But that reasoning has actually advanced as we have actually come to better recognize just how and for what functions civilization are making use of Alice. Like a Swiss army knife, Alice could be designed to carry out many points, reasonably well. However, a Swiss-army-knife-Alice would certainly most likely not execute anypoint incredibly well. As an analogy, MS Word can be supplied to geneprice acceptable presentations, yet it would certainly not serve this objective and also PowerPoint. They are different devices for various purposes.

Many crucial to the Alice team, but, is that our user base requires the maintenance of both. The Alice Suite of devices supports at leastern 2 (in fact, many) uses and desired outcomes for the courses in which Alice is being offered.At this time we watch Alice 2.x and also Alice 3.x as different devices for different audiences as identified by age teams, grade levels, and course outcomes/objectives.

One of the biggest sustaining forces for maintaining an Alice Suite containing both Alice 2.x and Alice 3.x is the curricular resources that are easily accessible for Alice 2 while the curricular sources for Alice 3 are still "under building." Alice 2 has actually multiple text publications as well as instructor assistance products ataliceprogramming.net.

Also, a well-off repository of K-12 instructional materials for Alice 2 have actually been developed and stored at Battle Each Other University"s Adendeavors via Alice site, maintained by Dr. Susan Rodger. Other repositories of Alice 2 products are additionally available. We carry out have some crossover job-related being done in model building. There has been a demand for new models for Alice 2, and the models being built tbelow are being designed so that they have the right to be carried into Alice 3.

Of course, the difficulty we currently have actually is overcoming the widespread perception that software program variation numbering indicates the second will certainly supersede the first. Perhaps it would certainly be helpful to remember that Algebra 2 does not replace Algebra 1.

From a research and also advancement perspective, Alice 2.x and Alice 3.x are supported by some of the exact same resources streams, however the Alice Project additionally various funding streams for both tools. Our obligations to those sources of capital require maintenance of both devices.In regards to our alarea of sources, we are devoting virtually all of our resources to Alice 3.x. Alice 2 is mostly in assistance mode.We are offering bug fixes, and providing limited attribute advancement and implementation, responding mostly to strong needs from our user base. For instance, our rapid growth approximately the world has spurred our occupational in developing a Spanish alternative of Alice 2.x. Incidentally, much of the labor-intensive job-related in developing the Spanish variation, the relabeling of the gallery has actually been done on a volunteer basis, by our partners in Costa Rica. Other langueras will be forthcoming.

Alice 2.x will be with us for the foreseeable future. As will certainly Alice 3.x.

How perform I see the Alice 2.x tutorial?

To view the Alice tutorial

Launch Alice and click on the "Start the Tutorial" button in the Welconcerned Alice dialogue box.You deserve to also jump to a specific tutorial by clicking among the tutorial human beings listed below the "Start the Tutorial" button.Tright here is a known bug in the fourth tutorial, on page 19, when asked to add the beach chair to the scene. Click on the Next button to obtain past this bug.

Can a user import their very own 3D models (and also if not is this function in the works)?

See the adhering to connect for indevelopment on structure and importing 3D models into Alice 2.x


Can I export to video the animations I produce in Alice?

Tbelow is a document food selection option for exporting an Alice world to video.This choice works well on Windows makers if tright here are no sound clips in the animation.

This alternative does not seem to be working at all on Mac OS X equipments.

Unfortunately we are still having actually difficulties through civilizations that usage tape-recorded sounds, including the reality that our exporter does not recognize that an animation might more than, because the background music might still be playing. For example, if I have a 45 second computer animation, however I am making use of as background music a 3 minute and also 15 second sound clip, then our exporter will desire to document all 3 minutes and also 15 secs.

But as the recorder is trying to usage the very same system media manager that is responsible for playing the recordings, other troubles current themselves also.

We are working on refixing these difficulties at the current time.

Possible solutions:

Clip the sound file in an audio editor, such as Audacity, so that it does not play any kind of longer than the computer animation. In the instance above, the sound clip should be trimmed to 45 secs tocorrespondto the 45 second size of the computer animation.

Ultimately customers will have actually the ability to export jobs to YouTube, will certainly this be limited to non-interactive tasks, favor previous versions of Alice?

Movies and also videos are by their nature non-interenergetic.The difficulty we are interested in solving is just how to create executable .jar documents so that students have the right to produce shareable interactive tasks.

Will Alice 2.x run on Windows 10?

We have actually installed and also are running Alice 2.x on a new Windows 10 machine (a Dell "All in One" via wiremuch less mouse and keyboard. Also, it has a touch screen). It is "alive and also well" and working just fine in Windows 10. We have actually additionally viewed installations of Alice 2 on the Windows Surchallenge Pro functioning without any kind of destruction in performance.

To install, we complied with (and recommend) these steps:

Downpack the zipped file (Alice2.x.zip or Alice2.xb.zip) to the desktop.Unzip on the desktop computer.Move the unzipped folder (containing all of the Alice files) to the Program Files (X86) folder on the C: drive.Create a shortcut on the desktop for Alice.exe.Click the shortreduced to start Alice.

By means of explanation: Vista, Windows 7, Windows 8, and also Windows 10 all have a solid malware security plan that resists installing non-standard software application straight on the hard drive. The ideal way we have discovered to work-related within this security plan is to unzip the Alice downfill on the desktop and also then relocate it to the tough drive.

Will Alice run on a Netbook?

On some, albeit very slowly and verging on the painful. We have actually taken strides to obtain Alice to run on netbooks, however the unfortunate truth is that the graphics capabilities are sindicate not up to snuff for transporting 3D content. With that shelp, as netpublications continue to enhance and Alice gets more efficient, we suppose performance to boost.

Alice is not designed to job-related on any kind of mobile gadgets at this time.

However, we understand also that it is possible to install linux on a Chromebook (view the following link:)


If you want to go dvery own this path, tright here are linux versions of both Alice 2 and Alice 3, but this is an implementation we have not yet tested.

We also have reports that Alice runs efficiently on the Microsoft Surconfront Pro, however not on the Surconfront RT. We have actually not tested this ourselves, but.

See the following connect of System Requirements for Alice:


NOTE: The Intel Integrated chipset that is found on many kind of notebook, netbook, and also various other machines has trouble trying to run Alice 3.x. Some higher-finish Vista machines have likewise had actually challenges. Decreasing hardware acceleration or decreasing shade resolution (form 32 bit to 16 bit) has sometimes been advantageous. See the section onVideo Requirementson theSystem Requirementspage for video driver update information.

Will Alice run on my smartphone/portable device/gaming console?


How much does Alice cost?

Alice is free. You have the right to download it, install it, teach with it, usage it as component of a not-for-profit undertaking. Just don"t downfill it and also sell it or redistribute it without correct acknowledgement and also permission of Carnegie Mellon University. If you want to review all the juicy fine print about what you have the right to and can not perform,inspect it out right here.

Seriously, there should be a catch.
