Now the ball is moving in the direction of 'arr', and my point here is that the ball followed where the arrow points
When arrow rotate, ball are turningkataryna2012-04-08 01:39:08

what is the "directionOfShoot" object ?

you need to put an angle, if you want to get an angle from coordinates you need two points. the "from" point and the "to" point
then to get the angle the formula is angle(from.x,from.y,to.x,to.y)
Here you're just putting an x and y coordinate separated by a coma, that's not something c2 understands

"directionOfShoot" its a sprite, when i shoot a ball, the ball should always fly to "directionOfShoot"

And this ball should be pushed by 'wind' (angle of "arr")kataryna2012-04-08 11:40:05

if I understand correctly you have 2 components :
- shooting direction
- wind force

if it's correct, I think you should do something like

[code]on Shot
-> Ball apply impulse shotStrength   at angle angle(ball.x,ball.y,directionOfShoot.x,directionOfShoot.y)[/code]

and for the wind
[code]Every ticks
-> Ball apply force windStrength at angle windAngle[/code]

shotStrength, windStrength and windAngle are values you have to figure out.Yann2012-04-08 17:41:14
