我需要制作一个“清除”按钮来删除屏幕和阵列中的所有图像。我目前正在使用EZ.removeAllEZElements();，但这清除了一切。甚至贴纸调色板和背景（画布）。如何从阵列和画布中删除所有放置的图片？
这是我的代码
sticker [] arraysticker = new sticker [80];
int image = 0;
int flag = 0;
else if (backgroundPicture.isPointInElement(clickX, clickY) && !savePicture.isPointInElement(clickX, clickY)
&& !loadPicture.isPointInElement(clickX, clickY) && !clearPicture.isPointInElement(clickX, clickY)
&& !rectanglePicture.isPointInElement(clickX, clickY)){
if (flag == 1){ //if hatSoundPlay is true
sticker sticker1 = new sticker();//creates a new sticker1
sticker1.sticker11("hat.png", clickX, clickY);//places sticker
arraysticker[image] = sticker1;//puts sticker 1 into the array
image ++;//increments image by 1
hatsound.play(); //and a hatsound will play
然后用if (flag == 2){然后3然后再重复3次。每个标志都是一个新贴纸。
这是我清晰的代码。
else if (clearPicture.isPointInElement(clickX, clickY)){
EZ.removeAllEZElements();
//make a clear array
EZ.addImage("background.png", EZ.getWindowWidth() / 2, EZ.getWindowHeight() / 2);
EZ.addImage("rectangle.png", EZ.getWindowWidth() / 2, EZ.getWindowHeight () / 7);
EZ.addImage("hat.png",1* EZ.getWindowWidth() / 10, EZ.getWindowHeight () / 6);
EZ.addImage("blunt.png",1* EZ.getWindowWidth() / 3, EZ.getWindowHeight () / 6);
EZ.addImage("dealwithit.png",3* EZ.getWindowWidth() / 5, EZ.getWindowHeight () / 6);
EZ.addImage("weed.png",10* EZ.getWindowWidth() / 11, EZ.getWindowHeight () / 6);
EZ.addImage("save.png", 19* EZ.getWindowWidth() / 20, 3* EZ.getWindowHeight () / 9);
EZ.addImage("load.png", 19* EZ.getWindowWidth() / 20, 4* EZ.getWindowHeight () / 9);
EZ.addImage("clear.png", 19* EZ.getWindowWidth() / 20, 5* EZ.getWindowHeight () / 9);
}
我正在清除所有图像并替换原始图像。问题是，带坐标的图像仍然存储在数组中。明确需要清除画布和数组。
这是我的整个代码。只删除EZ.addImage和EZ.addSound代码。
