Remove all children from Display Object

In this article we are going to use the following properties of method.

• numChildren
• removeChildAt( )

numChildren in AS3

numChildren is a public method available for all DisplayObjects in as3 which gives you the count, number of child objects inside the parent object.

Suppose there are 3 sprites inside the parent MovieClip named containerMC then we can count the number of sprites inside the containerMC by

trace("Children Count: "+containerMC.numChildren)

output:

Children Count: 3

removeChildAt() in AS3

Removes the children at given depth, depth we pass as argument.

Example:

parentContainer.removeChildAt(0);

Above code removes the children at depth “0″ from parentContainer.

Note: In as3 if we remove an child object from middle of display object then the depth will be rearranged itself.

AS3 Remove all children

while( container.numChildren > 0 )
container.removeChildAt( 0 );
}

Above code removes all the children from the parent container until there is no child left.
