[CharacterControl] Character Movement

Hi Kirupa,

Having a issue of the property '_rotation'


How this '_rotation' property works? In my game, i want is , the character is rotated in to that direction once that key is pressed.

this is my code, this is nested in the enterframe event

======script==============
//Rotation
if (Key.isDown(Key.UP))
{
if (_rotation > 0)
{
_rotation--;
}
}
if (Key.isDown(Key.RIGHT))
{
if (_rotation < 90)
_rotation ++;
{
}
=========/script==========

The problem with this code is the character doesn't stop rotating once at the correct orientation.

anyone can help?

rotations in Flash are based with the orientation pointing right on the x axis, with a range from 0 to 180 CW and 0 to -180 CCW - all flash calculations will resolve to these ranges, which are also related to radian values of the unit circle and general trigonometry - although you can assign larger values, for instance 360, it will be resolved to 0 if you were to trace the current rotation of the Object - another example: 270 == -90

in your example, since you are rotating the object by fixed increments - you should simply be able to adjust your conditional values to what you need - as in:

if( Key.isDown(Key.UP) && _rotation > -90 ) { _rotation--; }
if( Key.isDown(Key.DOWN) && _rotation < 0 ) { _rotation++; }

the way you have this structured the controls should rotate the knob between "up" and "right" according to you diagram
