最近在制作flash時(shí)需要制作一個(gè)可以隨意設(shè)定寬度的按鈕組件.為了保證按鈕樣式不變形,一般都會(huì)采用將按鈕分成幾個(gè)mc的方法來(lái)制作.但其實(shí),如果對(duì)按鈕的動(dòng)態(tài)效果要求不多的話,完全可以使用Bitmap類(lèi)來(lái)制作.下面是將按鈕的一個(gè)狀態(tài)分解開(kāi)來(lái).一般的思路是做為三個(gè)MC,然后在改變寬度是,動(dòng)態(tài)改變中間mc的寬度就可以了。但是這樣的話,對(duì)于元素的制作就比較麻煩.使用bitmap類(lèi)可以直接將一張圖片分為三個(gè)MC后生成.在批量使用時(shí),效率提高了不少.
