• 如何在图西斯-奥奇处绘制一个比图?
原标题:How to draw an Bitmap in Graphics-Object at any position?

有可能为像图象-目标这样的地图绘制一个比图。

this.graphics.beginBitmapFill(bitmapData, matrix, false);
this.graphics.drawRect(0, 0, w, h);
this.graphics.endFill();

with an offset? A simple moveTo(x, y) call before beginBitmapFill does not work :/ Neither does changing the x and y value of drawRect... (That just seems to have the same effect as an translation with the matrix...) Additionally I don t want do draw that thing in a separate Graphics-Object and add that one into the other...

任何cl?

问题回答

这里的答案是很晚的,但由于我在谈论这个问题时发现这个问题,我对我说的是,我再加回答。

您可使用矩阵翻译和职位组合,以吸引人,在图形标的任何位置上绘制一份比图:

var positionX:int = 100;
var positionY:int = 200;
var matrix:Matrix = new Matrix();

matrix.tx = positionX;
matrix.ty = positionY;

graphics.beginBitmapFill(bitmapData, matrix);
graphics.drawRect(positionX, positionY, bitmapData.width, bitmapData.height);
graphics.endFill();

坦率地说,我从来没有真正充分地理解矩阵是什么? 并且对如何使用这种矩阵没有任何直观的感觉,因此,可能还有其他、也许更好的方式这样做,但上述情况对我来说是可行的。

您可使用比特马达塔(您的比图)法或复制本。
