alice-teacher Alice 2.4.3 Speech bubbles question w/ code attached

Sat Oct 31 17:38:30 EDT 2015

Another thought…  We suspect that the JOGL in some video drivers is a "scaled down" version of the JOGL used we use. This is a especially a problem in tablets where the video driver is scaled down in preference
to using DirectX. 

It would be helpful to know just which video adapters are the culprit.  It may be that updating the driver... not the one automatically accessed through Microsoft Windows, but the one from the manufacturer of the video adapter might solve the problem. In the past, the video driver from the manufacturer seems to have the larger JOGL set.

Something else too investigate…

All the best,
Don Slater

Just an update on the speech bubbles not connecting up with the characters. We have narrowed it down to a driver issue with the student tablets. JOGL is not on the tablets, and apparently the tech people don't want to add it to the image. They are working with DirectX to see if it will make a difference. Thank you for the suggestion to look at how it was being rendered, that was the key. If we ever nail it down I will post the solution, for right now we are working through it.

Thank you all

I have 2 questions:
1 - Are the Oculus or VR heads sets compatible with Alice?

Not at this time, but it is a very intriguing idea...

2 - In one exercise it states to position the turtle 2 meters from the stool. Is this trial an error or is there a way to know exactly how far one object is from another?

The turtle (and all Alice models) has a function “getDistanceTo”, which will return the distance from the midpoint of the Turtle to the midpoint of the target object. Alice 2. Click on the functions tab in the details panel, after clicking on the turtle object in the object tree.

Let us know if you have any other questions…

That is not what he is getting. On his the speech bubble is pointing to the left side of the screen. Interestingly I took this down and put the program on one of the older desktops in the lab and it played fine. Could this be a driver issue? I will try and catch up with the student today and get a screen shot.

See attached three screen captures…

The first - beeSay - is what I get when I run your code on my machine, A Macbook Pro Retina with Alice 2.4.5, If your image is significantly different, please send us a screen shot so that we can see what you see.

The second image - beeHeadSay - is what I see when I run your for;s and have the bee’s head say execute the say statement. I suspect that is closer to what you would expect.

The third image - beeBoundingBox - shows the bounding box of the bee model, and you will see that the spear, which is the tallest part of the model is included in the bounding box, and when you execute the bee say statement, the speech bubble seems too locate itself on the spear, top of the bounding box.

Let us know if you you have questions or continue to have problems…

All the best,

Sorry for the delay in getting back. Attached is the code.

Problem: the character (tutorial 4-3, Nested if/else instructions, Tony Gaddis's Alice 3rd edition) is asking for the password. The speech bubble is not pointing to the character, but is off in the distance.

We have tried, deleting and re-adding the character. I checked, there are no phantom off screen characters. This is happening with more than 1 student. (3 out of 18 students). We are using Windows 8. All are working on tablets; 2 are Fujitsu Lifebook T series, 1 is ThinkPad X230 Tablet. We have rebooted. Shutdown and restarted. Even when the code is saved and then run on another machine it still does the same thing. 

It is probably incredibly simple and something that I am overlooking.

Thank you in advance for the help
