我很难与 EaselJS 一起工作。基本上我想创建一个简单的网格并突出显示选择的实际元素:
var stageWidth = 800,
stageHeight = 600,
cell_size = 50,
w = 16,
h = 12,
n = w * h,
canvas,
stage,
background;
$(document).ready(function(){
canvas = $("#container")[0];
stage = new createjs.Stage(canvas);
var x_pos = 0,
y_pos = 0,
res = 0,
grid_el;
for(i=0;i<n;i++){
res = i%w;
if(i>0){
if(res===0){
x_pos = 0;
y_pos++;
} else {
x_pos++;
}
}
grid_el = new createjs.Shape();
grid_el.graphics.setStrokeStyle(2,"square").beginStroke("#000000");
grid_el.graphics.beginFill("#70FF85");
grid_el.graphics.rect(x_pos * cell_size,y_pos * cell_size,cell_size,cell_size);
grid_el.x_pos = x_pos * cell_size;
grid_el.y_pos = y_pos * cell_size;
grid_el.name = "quad";
stage.addChild(grid_el);
}
stage.update();
stage.onMouseDown = function(e){
console.log(e);
var quad = this.getObjectsUnderPoint(e.stageX,e.stageY);
var clone = quad[0].graphics.clone();
clone.beginFill("#51D9FF");
quad[0].graphics = new createjs.Graphics(clone);
stage.update();
}
});
我尝试克隆实际元素的图形属性,更改填充颜色然后更新舞台,但我只获得了一个白色元素,就像它没有识别新的图形属性一样。
谢谢你的帮助。
