emptying an array
Mar 17th, 2006, 2:58am  
Hi

I've built a small drawing program that stores the points in a 2D array.

I want to be able to empty the array and start drawing again with a clean screen.

Is there a syntax that will empty the array entirely, setting the length to 0 again?

something like

myArray.length = 0;

I can set each entry in the array to 0 with a "for loop" but that doesn't alter the length of the array.

Cheers
Rhian

If it is an array of objects

myArray = new ArrayType[0];

If it is an array of floats

myArray = new float[0];

Replace 0 with whatever number your array size is supposed to be.
