How do I set up a key listener

[geek in training]

Step 1: add an object to the world, any object, you can even use the camera if you want

Step 2: in that object's procedures, add a keyeventlistener method to your code

Step 3: drag an if block inside the key listener and select 'true'

Step 4: select the arrow next to 'true' and select 'keyevent e =' then proceed to select whatever key you wish to bind to whatever action

this was posted by antmj2317 in the key listener and mouse button listener thread http://www.alice.org/community/showt...0083#post40083

for step 4 you could use "e is key (choose a key)" instead of "keyevent e ="

Thanks for the info.

I'll have to try that NetBeans thing at some point.

you mean the net beans plugin for Alice 3? what does that do?

[x2495iiii]

It lets you import the world you've made into a more traditional java editing interface, allowing you more freedom over the raw code of the Alice world.

This should mean that the code can be exported into other formats besides Alice Worlds, but I haven't tried it, so I don't know.

To get a KeyListener in Alice 3


1. Select the scene instance
2. The listener events available will be in the procedures listing
3. Select the addKeyListener
4. Bring an if down into the "do in order" section of the keyPressed procedure
5. Options for what the KeyEvent parameter e will now be available for selecting in the if conditional section.
6. Place your procedures for if/else into the sections.

PS- I'm on linux too, so I'm forcing my students on Mac and PC to work on Alice 3. Currently at 3.0.0.3
So far I've found Alice 3.0.0.3 and 3.0.0.2.10 unstable on Ubuntu 11.04, but fine on 10. I'm using 10.04 LTS for my classroom machine and 10.10 at home. Also couldn't get it to work on Linux Mint 11

On Mac OS X, we couldn't get 3.0.0.2.10 to go on systems under 10.6. We did get 3.0.0.3 to work fine on 10.5.x
