[b]Pour uploader le tweener menu, j'ai un fichier XML dont voici le code :[/b]

[code=xml]<?xml version="1.0"?>
<menu>
	<item bkg="0x6B6052" url="http://www.flashcomponents.net">
		<content><![CDATA[<font color="#FFFFFF" size="23px">PAYSAGES IMAGINAIRES</font>]]></content>
	</item>
	<item bkg="0xE44A25" url="http://www.flashcomponents.net">
		<content><![CDATA[<font color="#FFFFFF" font-weight="bold" size="23px">LES Z'AMIS Z'ANIMAUX</font>]]></content>
	</item>

on (release) {
	menu1.targetx = 0.0;
}
