There are several ways to implement object flip: (Here we only talk about simple flip, horizontal or vertical flip, only consider results, not the flip process, because some flip processes are very complexAlgorithm)

 

1. Directly fromFlashMenu.

 

Select a visual object from the menu "modify"-"deformation"-"vertical flip" or "modify"-"deformation"-"Horizontal flip" to flip the object.

 

2. UseScalexAndScaleyAttribute(As2This method is often used.).

 

Implement horizontal flip:Displayobject. scalex =-displayobject. scalex;

Implement vertical flip:Displayobject. scaley =-displayobject. scaley;

 

3. ExploitationMatrixClass.

 

Horizontal flip:

Function fliphorizontal (DSP: displayobject): void

{

VaR matrix: matrix = DSP. Transform. matrix;

Matrix. A =-1;

// Matrix. Tx = DSP. Width + DSP. X;

DSP. Transform. Matrix = matrix;

}

 

Vertical flip

Function flipvertical (DSP: displayobject): void

{

VaR matrix: matrix = DSP. Transform. matrix;

Matrix. d =-1;

// Matrix. Ty = DSP. height + DSP. Y;

DSP. Transform. Matrix = matrix;

}
