He meant that the line: my_array.push(z)=z;
should be: my_array.push(z); You're right about recreating the array, you could leave out the delete my_array and just overwrite it with new Array().

Well my plan was to fill up the array with object's-name that are visible in the configurator (active ones) cause the invisibles ( _alpha = .25 ) are not important for the user (inactive ones). The thing with the low-level memory ist hat I don't know how Flash handles it, in C++ the Developer ist he one to manage that problem. But I guess u're saying it works more or less like Java (with a garbage-collector) since it works on VM. >> Yes, it is wrong of course, since only a variable or property can be >> on the left side of an assignment.

Sorry, but I don't know which assignement you exactly refer to, do you mean " my_array.push(z)=z; "? It's only a test-code to show me a value has been stored in the array. Thnx 4 that quick answer Attila. Cryzto ;-) -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Rákos Attila Gesendet: Freitag, 18.

In general you don't have to care about low-level memory management in Flash at all, the VM is responsible for such tasks.

No loop is required, a simple splice(0) is enough. Or you can create a new array instance, too - of course.
