Как сделать background автозаполнение?
... Т.е. взять маленький кусочек bg и раскопировать его...
Как в ХТМЛе функция?
нашел прототип такой штуки, но не понял как им пользоваться :confused:
Код:
/* Stage.tileImage([linkageName], [stageAlignX], [stageAlignY], [alpha], [tileTarget])
--------------------------------------------------------------------------

--------------------------------------------------------------------------
Parameters:
[linkageName] = the library linkage name of the mc containing the image to
tile;
[stageAlignX&Y] = configures starting point of tile according to stage vertical
& horizontal alignment: "left", "center", "right"; note this
does not set the Stage.align parameter, merely aligns the tile
according to that alignment.
[alpha] = alpha of the tile image;
[tileTarget] = optional; target clip within which to create the tile (may be a
clip object or a string); note tileTarget must be full path
if clip is not in the same place as function call; if tileTarget
is absent, the tile is created in an empty movie clip below
all author-time content.
Usage:
// Best used with Stage.scaleMode = "noScale" so that the tile fills the browser window;
// creates tile from backgroundTile library mc into an empty clip with a default alpha
// of 100 situated below all author-time content with a stage alignment of dead-centre
Stage.tileImage("backgroundTile", "center", "center");
//... with a stage alignment of left¢re
Stage.scaleMode = "noScale";
Stage.align = "L"; // left centre
Stage.showMenu = false;
// don't show the menu, cause if you zoom you'll never get the stage size
// to normal back unless you reload the page
Stage.tileImage("backgroundTile", "left", "center", 99);
// creates tile from backgroundTile library mc into clip named "background_mc"
Stage.tileImage("backgroundTile", "center", "center", 99, "background_mc");
Note: we don't use 'prototype' when creating the function because Stage is a fixed object
and not a class
*/
Stage.tileImage = function(linkageName, stageAlignX, stageAlignY, alpha, tileTarget) {
// get the Movie size
var stageState = stage.scaleMode; // remember the initial state

// that appears beneath all author-time content.

var bgTarget_mc = eval("_root."+tileTarget);
} else if (typeof tileTarget == "movieclip") { // if tileTarget is an object
var bgTarget_mc = _root[tileTarget._name];
// Note: we write this instead of _root.tileTarget, in case the user inputs "_root.name",
// which would result in "_root._root.name", crashing the function
} else {
return; // function fails silently

}
