alice-teacher Lists on Alice 3.4

[Don Slater]

Mourad,
Dynamically creating objects during runtime in Alice is not possible. All objects that may be used in an Alice world have to be added to the object, and possibly hidden until needed, before the project executes.

To drag and drop an object in a project while it was running (see that attached screen shot), go to initializeEventListeners tab (1), click on Add Event Listener button (2), select Mouse from the menu (3), and select addDefaultModelManipulation listener.

This will allow you to click and drag any model in the scene. Holding down the Control key (Windows) (Option key - Mac) will turn the object. Hold the Shift key and drag an object to raise or lower an object.

Let us know if you have any other questions.

All the best,
Don Slater

Alice Project

The attached set of Powerpoint slides should show how how to build an array structure in Alice and how to use the “for… each” and the “each … in together” data structures use for manipulating elements in the arrays.
