var nInter = setInterval(rotate, 100); var increase:Number = 5; function rotate():Void{ ym.text = _root._ymouse + ", " + _root._xmouse; myRadians = Math.atan2(_root._ymouse-tank._y, _root._xmouse-tank._x); myDegrees = Math.round((myRadians*180/Math.PI)); if(tank._rotation > myDegrees+90) { tank._rotation -= increase; } if(tank._rotation < myDegrees+90) { tank._rotation += increase; } } okay, basically it gets the slope of the mouse to the tank turret i made...but when the mouse is in the lower left quadrent it just moves in complete circles without stopping...besides the lower left quadrent it works fine. i know its somthing to do with my ifs but i dont know what!

here is some code i found that does the same thing i need, but its obfuscated

  protected void spinTank(int i, int j, int k, int l)    {        if(k == i && l == j)            return;        if(i > 0 && i < 17 && j > 0 && j < 17)        {            int i1 = i * 24 + 12;            int j1 = j * 16 + 8;            int k1 = k * 24 + 12;            int l1 = l * 16 + 8;            double d = Math.atan2(i1 - k1, l1 - j1);            d = (8D * (d + 3.1415926535897931D + 0.19634954084936207D)) / 3.1415926535897931D;            int i2 = (int)d % 16;            int j2 = zona[j].direction & 0xf;            if(j2 != i2)            {                if(j2 > i2)                {                    if(j2 - i2 >= 8)                        j2++;                    else                        j2--;                } else                if(i2 - j2 >= 8)                    j2--;                else                    j2++;                if(j2 >= 16)                    j2 -= 16;                else                if(j2 < 0)                    j2 += 16;                zona[j].direction = (byte)((zona[j].direction & 0xf0) + j2);                buildScreen = true;            }        }    }

the code there is java heres my code to repeat this in flash...

var nInter;var ymouse:Number = 0;var xmouse:Number = 0;var singleclick:Number = 0;_root.onMouseDown = function(){ymouse = _root._ymouse;xmouse = _root._xmouse;if(singleclick === 0){	singleclick = 1;nInter = setInterval(rotate, 20);}}var increase:Number = 1;function rotate():Void{	ym.text = ymouse + ", " + xmouse;	myRadians = Math.atan2(ymouse-tank._y, xmouse-tank._x);        myDegrees = Math.round((myRadians*180/Math.PI));	   if(tank._rotation >= myDegrees+90)	   {		 		   tank._rotation -= increase;	   }       if(tank._rotation <= myDegrees+90)	   {		  		   tank._rotation += increase;	   }	   	   if(tank._rotation == myDegrees+90)	   {		   singleclick = 0;		   clearInterval(nInter);	   }	   }

only thing wrong with mine, is that when i click in the lower left qudrant it goes ALL the way around to the right to get to it, because after i rotate 180 degrees the rotation turns negative....any idea on how i can stop this?

well im guessing no body here has the brains to figure it out just like every other forum :sheesh: oh well

good way to keep it positive... play around with the code.
