c# - SendInput is blocked in fruit ninja for pc -

i writing program uses sendinput function simulate mouse events play fruit ninja pc. when called sendinput, mouse moved nothing happened on game screen. tell me why doesn't work , give me solutions? programmed on c# , used [dllimport] call sendinput function. thanks.

i suggest simulating mouse move. should simulate mouse drag. first mouse down -> mouse move -> mouse up

here code old project:

namespace clicker.enums {     public enum mouseevents     {         move = 0x0001, /* mouse move */         leftdown = 0x0002, /* left button down */         leftup = 0x0004, /* left button */         rightdown = 0x0008, /* right button down */         rightup = 0x0010, /* right button */         middledown = 0x0020, /* middle button down */         middleup = 0x0040, /* middle button */         xdown = 0x0080, /* x button down */         xup = 0x0100, /* x button down */         wheel = 0x0800, /* wheel button rolled */         virtualdesk = 0x4000, /* map entire virtual desktop */         absolute = 0x8000 /* absolute move */     } }  namespace clicker.actions {     public class action     {                 protected int x;         protected int y;          ...          [dllimport("user32")]         protected static extern int setcursorpos(int x, int y);          [dllimport("user32.dll", charset = charset.auto, callingconvention = callingconvention.stdcall)]         protected static extern void mouse_event(int dwflags, int dx, int dy, int cbuttons, int dwextrainfo);          ...          public int x { { return x; } set { x = value; } }         public int y { { return y; } set { y = value; } }          ...          public vritual void performaction()         {          }          ...     } }  namespace clicker.actions {     public class drag : action     {         public int to_x { get; set; }         public int to_y { get; set; }          ...                  public override void performaction()         {             setcursorpos(x, y);             thread.sleep(100);             mouse_event((int)mouseevents.leftdown, 0, 0, 0, 0);             setcursorpos(to_x, to_y);             thread.sleep(100);             mouse_event((int)mouseevents.leftup, 0, 0, 0, 0);         }          ...     } } 

using:

action slisefruit = new drag(){      x = 0, // (x=0, y=0)     y = 0, // (x=0, y=0)     to_x = 100, // (x=100, y=100)     to_y = 100, // (x=100, y=100) };  slisefruit.performaction(); 

here more suggestions: issue can in synchronizationcontext and/or threading if want click outside main form of application. possible solution:

namespace clicker.actions     {         public class action         {                     protected int x;             protected int y;              // add fields             private static synchronizationcontext _context = null;             public static synchronizationcontext context { { return _context; } set { _context = value; } }              ...              [dllimport("user32")]             protected static extern int setcursorpos(int x, int y);              [dllimport("user32.dll", charset = charset.auto, callingconvention = callingconvention.stdcall)]             protected static extern void mouse_event(int dwflags, int dx, int dy, int cbuttons, int dwextrainfo);              ...              public int x { { return x; } set { x = value; } }             public int y { { return y; } set { y = value; } }              ...              // ... , method             internal virtual void innerperformaction(object state)             {                  return;             }              // change performaction             public void performaction()             {                 innerperformaction(new object());             }              ...         }     } 

now edit drag action class:

namespace clicker.actions     {         public class drag : action         {             public int to_x { get; set; }             public int to_y { get; set; }              ...                      internal override void innerperformaction(object state)             {                try                {                    context.send(new sendorpostcallback(delegate                        {                            setcursorpos(x, y);                            thread.sleep(100);                            mouse_event((int)mouseevents.leftdown, 0, 0, 0, 0);                            setcursorpos(to_x, to_y);                            thread.sleep(100);                            mouse_event((int)mouseevents.leftup, 0, 0, 0, 0);                        }), state);                 }                catch                {                    //aaaaahh... ever...                }             }              ...         }     } 

almost forgot:

// have in main form constructor action.context = synchronizationcontext.current; 

i've created simple solution code, , works fine. if want can send email or something.
