_Rotation in Flash
Author
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!

there you go...check that out and you will see what i mean i dont under stand! the other three quadrants work!

here is some code i found that does the same thing i need, but its obfuscated
the code there is java heres my code to repeat this in flash...
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?
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...
