// The following is used for duplicating movie clips and applying various actions to them. // All references are local so it can be used on any timeline. clipFunctions = function () { // Initialize position and / or variables. // "clipIncrement" will equal the current "i" value passed from the "for" loop found below that is used to create the clips. // Note that when used inside a movie clip, x = 0 and y = 0 will be in the center of the container clip regardless of the clips // placement on the main stage. // If the clips are created on the the main stage, or "_root", x = 0 and y = 0 will be in the upper left corner of the main movie. // Flash "y" direction + /- values are opposite from a graphs in that y increases as you go farther down. this.init = function(clipIncrement) { this._x = this._width * clipIncrement; this._y = this._height * clipIncrement; // The movie is 450px x 450px. this.xLimit = 225 - (this._width / 2); this.yLimit = 225 - (this._height / 2); } //**************************************************** // For "onEnterFrame" actions if needed. this.move = function() { this._x += 4; this._y += 4; if(this._x > this.xLimit) { this._x = this.xLimit * -1; } if(this._y > this.yLimit) { this._y = this.yLimit * -1; } } //**************************************************** // Button actions if needed. this.buttonPress = function() { removeClips(); } } //**************************************************** setClips = function () { for (i = 0; i < 10; i++) { // To use attachMovie, right click the desired clip in the Library, select Linkage, name it (named below as "clipExport"), // and check the "Export for actionscript" and "Export in first frame" checkboxes. // The linkage name can be the same as the clip's name in the library or a different one. // Usually this is the better way to go since you don't have to have a clip on stage to duplicate, and you can use the // "removeMovieClip" method on the clip instances. // Each clip will need a unique instance name, assigning the name to a variable will simplify later references to it. // The end result will be 10 clips named "clipExport0" through "clipExport9". name = "clipExport" + i; // Note that "this" as used here refers to the current timeline, All other uses (except in the removeClips() function) // refer to individual clips. this.attachMovie("clipExport", name, i); // This alternate way will duplicate a clip on the stage with an instance name of "clip" but you won't be able to use // "removeMovieClip" on them. //name = "clip"+i; //this.clip.duplicateMovieClip(name, i); clipFunctions.apply(this[name]); // Initiate the clips and pass the current value of "i" to the init() function. this[name].init(i); // Apply event handlers as needed. this[name].onEnterFrame = this[name].move; this[name].onPress = this[name].buttonPress; } // Used with duplicateMovieClip to hide the original clip being duplicated. // It is usually better to hide a clip than to apply the same functions the "for" loop did to the duplicates because the // name won't be "numerically inline" with the others and can make later references to the clip a pain. // An advantage of duplicateMovieClip is that you can use the clip on stage for laying out the placement of the rest // of the clips. // If the setClips() function is called more than once, enter the line "this.clip._visible = true;" above the "for" loop. //this.clip._visible = false; } //**************************************************** // Called by the button handler, this will remove the clips from the stage. removeClips = function () { for (i = 0; i < 10; i++) { name = "clipExport" + i; if(this[name]) { removeMovieClip(this[name]); } } } //**************************************************** setClips(); |
