gestures - Determining a fling from a pan in libgdx -

i'm developing game libgdx , i'm having trouble determining fling pan.

my gesturelistener:

@override public boolean fling(float velocityx, float velocityy, int button) {     //if (velocityx > 1000f) {     // can use exclude slow pans executing fling         system.out.println("flinged - velocityx: " + velocityx + ", button: " + button);     //}     return false; }  @override public boolean pan(float x, float y, float deltax, float deltay) {     // there doesn't seem way have not fire on fling     system.out.println("panned - deltax: " + deltax);     return false; }  @override public boolean panstop(float x, float y, int pointer, int button) {     system.out.println("pan stop - pointer: " + pointer + ", button: " + button);     return false; } 

the problem if both pan , fling fire. understand fling fast pan, need able determine between 2 gestures can handle each 1 separately.

a succinct way of asking is, how provide unique actions fling , pan?

the reasonable solution in opinion use longpress set boolean flag 'enter panning mode' when swiping without long press making fling.

this how see this:

    //the flag checking if pan mode entered     boolean pan = false;      @override     public boolean longpress(float x, float y) {         pan = true;         return false;     }      @override     public boolean fling(float velocityx, float velocityy, int button) {         if(!pan) {             system.out.println("flinged - velocityx: " + velocityx + ", button: " + button);         }         return false;     }      @override     public boolean pan(float x, float y, float deltax, float deltay) {         if(pan) {             system.out.println("panned - deltax: " + deltax);         }         return false;     }      @override     public boolean panstop(float x, float y, int pointer, int button) {         if(pan) {             pan = false;             system.out.println("pan stop - pointer: " + pointer + ", button: " + button);          }         return false;     } 

of course if longpress long purposes can change using setlongpressseconds(float longpressseconds) method of gesturedetector instance
