将指定的矩阵属性附加到此矩阵,这相当于乘以(此矩阵)*(指定矩阵)
Prepends the specified matrix properties to this matrix.这相当于乘以(指定矩阵)*(此矩阵)
p.appendMatrix = function(matrix) {
return this.append(matrix.a, matrix.b, matrix.c, matrix.d, matrix.tx, matrix.ty);
};p.prependMatrix = function(matrix) {
return this.prepend(matrix.a, matrix.b, matrix.c, matrix.d, matrix.tx, matrix.ty);
};从指定的显示对象转换属性生成矩阵属性,并将其附加到此矩阵。非常有用
function demo1 () {
let box = game.add.box(100, 100, 'red', {
x: 100,
y: 100,
rotation: 60
})
console.info(box)
let mtx = new createjs.Matrix2D()
// 把box的位置信息转换成一个Matrix2D,并append到当前的Matrix2D上
let resMtx = mtx.appendTransform(box.x, box.y, box.scaleX, box.scaleY, box.rotation)
console.info(resMtx)
let box2 = game.add.box(50, 50, 'blue')
// 现在box2会用box的矩阵变换
// box2.transformMatrix = resMtx
// 或直接获取box的matrix
box2.transformMatrix = box.getMatrix()
}
