Mouse moving.

What API are you using? GLUT, Win32, MFC, or what? Depending on what you are using, get the mouse coordinates when a button is clicked (the routines are different depending on the API used), the y-coordinate will be upside down most likely, so flip it, and then you have a vector that is (player.Position, Mouse.Position). Do a little linear interpolation based on that line, and there you have it.

im using win32 one...
case WM_LBUTTONDOWN:
case WM_RBUTTONDOWN:
// /* if we don't set the capture we won't get mouse move
// messages when the mouse moves outside the window. */
SetCapture(hWnd);
mx = LOWORD(lParam);
my = HIWORD(lParam);
if (uMsg == WM_LBUTTONDOWN){
player.pos.x=mx;
player.pos.y=my;
}
if (uMsg == WM_RBUTTONDOWN)
player.pos.y=my;
return 0;

this is what I had the last time,the problem is that I have no aceleration there...im very bad in this sort of things,could you give me a code example for doing that?thank you a lot!

Are you refreshing the display after you update the player x and y positions?

sure I do,just wanna see how to make the aceleration in the correct "direction" because it is just teleporting atm.thx

if its teleporting to the right spot, at least you've got a start ;) to get it to move their over time, you're going to have to setup a basic animation system. basically, you impliment a timer and tell it to move part of the way down the path based on the amount of time that has passed (using linear interpolation, as xg0blin said, to figure out where on the line you'll be). I know that isn't too specific, but if you get anything out of this message, note the keywords "timer" and "linear interpolation" ;) good luck!

Hey instruo,thanks a lot.I am talking about something like Diablo 2,you click in a spot,and player goes there with speed.So that is what I need to do?if yes,I will look at google.thank you!

Yes, that's exactly what you need to do. Linear interpolation moves something from one state to another. You set up a timer (as he said) and every n milliseconds or whatever move a little farther down your line (the line is from the player to the mouse coordinates) until you get to from the start coordinates to the mouse coordinates. Look up linear interpolation on google, and you should be good.
