shooting with angle

[alekos]

good morning to all i am in serious trouble with a code i want a bullet to follow the angle of a cannon but no in straight direction but following the angle please help me

[alekos]

this is what i have done but i want when i push the cannon a bomb will follow the direction of the cannon.for example if the cannon looks on the top the bomb will go on the top but with angle please help me someone with a fla :( :( :(

[alekos]

this is my code for the shooting with angle but it isn't running can anyone help me please!!!!

_root.createEmptyMovieClip();
onMouseDown = function () {
g = 9.81;
v = 1;
cos_angle = Math.cos(_level0.kanoni.myDegrees);
sin_angle = Math.sin(_level0.kanoni.myDegrees);_
root.sfaira._visible = 1;
_root.sfaira._x = _root.kanoni._x;
_root.sfaira._y = _root.kanoni._y;
for (var i = 0; i<155; i += 0.1) {
balla_x = (v*v/g)*(sin_angle);
balla_y = (v*v/g)*(sin_angle)*(sin_angle);
_root.sfaira._x = _root.sfaira._x+balla_x;
_root.sfaira._y = _root.sfaira._y+balla_y;}};

sin_angle = Math.sin(_level0.kanoni.myDegrees);_

Try to delete _ after ;

A ball shall go from coordinats (1,1) to (100,100);
First you calculate the diffrences between the corr.
x1 =1;
y1= 1;
x2 =100;
y2 =100;

diff_x = x2-x1; // Res. 99
diff_y = y2-x2;

The you have to calculate the diffrence in time. For exampel if it shall take 10 sec. from (1,1) to (100,100).

var timeWp2Wp:Number;
var time2Wp2:Number;
timeWp2Wp = this.time2seconds(TimeWP2)-this.time2seconds(TimeWP1);
time2Wp2 = this.time2seconds(TimeWP2)-this.time2seconds(this.getCurrentTime());
/*Multiple with 1000, to avoid rests*/
distance = (1-(time2Wp2/timeWp2Wp))*1000;
distance = Math.floor(distance);
distance = distance/1000;


here I calculate where the ball shall be. After 5 sec the ball shall be in the middle.
..time2seconds is my own function thats recalculate hour to seconds.

this._x = int(diff_x)+int(diff_x*distance);
this._y = int(diff_y)+int(diff_y*distance);

can anyone send a fla to help because i don't understand what to do here is what i have done please help me i would be very gratefull here is my code for the rotation can you send me any fla to help me

onClipEvent (enterFrame) {
if (!_root.motionFlag) {

myRadians = Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x);
myDegrees = Math.round((myRadians*180/Math.PI));
_root.yChange = Math.round(_root._ymouse-this._y);
_root.xChange = Math.round(_root._xmouse-this._x);
this._rotation = myDegrees+145;
}
onMouseDown = function () {

g = 9.81;
v = 1;
cos_angle = Math.cos(_level0.kanoni.myDegrees +180);
sin_angle = Math.sin(_level0.kanoni.myDegrees +180);
_root.ball._visible = 1;
_root.ball._x = _root.kanoni._x;
_root.ball._y = _root.kanoni._y;

_root.motionFlag = true ;

};




sth ball


/* xi = v*cos_angle * i;
yi = v*sin_angle - 0.5*g*(i*i);
_root.ball._x = xi ;
_root.ball._y = yi;
trace("x:" + xi + " - y:" + yi )
*/

onClipEvent (enterFrame) {

g = 9.81;
v =- 0.01;
cos_angle = Math.cos(_level0.kanoni.myDegrees +180);
sin_angle = Math.sin(_level0.kanoni.myDegrees +180);

if (_root.motionFlag) {

i+=2
xi = v*cos_angle * i;
yi = v*sin_angle - 0.5*g*(i*i);
yi = yi/1000
xi = xi*10
_root.ball._x = _level0.kanoni._x + xi ;
_root.ball._y = _level0.kanoni._y + yi;
trace("x:" + xi + " - y:" + yi )

}

}
