movement - Bullet direction in c# -

-

i trying make game have turret rotates mouse position, , on click firing bullets towards mouse position. problem using method (below) doesn't make bullets go straight, since can go in up, down , 45 degree diagonal direction. also, can't figure out way make bullets continue direction after reaching mouse position. suspect whole approach problem may wrong... (as i'm new c#). appreciated, thank you.

private void timer1_tick(object sender, eventargs e) {  int x = picturebox1.location.x;  int y = picturebox1.location.y;  if (picturebox1.location.x < cursor.position.x - picturebox1.width / 2)  {      x = x + 3;      picturebox1.location = new point(x, y);  }   if (picturebox1.location.x > cursor.position.x - picturebox1.width / 2)  {      x = x - 3;      picturebox1.location = new point(x, y);  }  if (picturebox1.location.y > cursor.position.y - picturebox1.height / 2)  {      y = y - 3;      picturebox1.location = new point(x, y);  }  if (picturebox1.location.y < cursor.position.y - picturebox1.height / 2)  {      y = y + 3;      picturebox1.location = new point(x, y);  } }

you can quite solve problem regards direction holding bullets velocity in array:

int[] bulletvelocity = {vx, vy};

where vx velocity in x direction , likewise vy y. these determine how change bullets x , y position @ each timer tick.

to make them fly towards bullet need register click position , hold bullet in question. 1 solution have bullet class , have point object within can set mouse click position.

you use point set initial velocity bullet, e.g. x , y proportionate different in x , y components of bullet , click.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
