Two actors . . . a spawner actor and and arrow actor.

The Spawner actor has a rule that says when mouse button is down or when touch is pressed (or whatever you want to trigger the arrow) then . . .

Spawn Arrow

Direction:

vectorToAngle(Mouse.Position.X-self.Position.X, Mouse.Position.Y-self.Position.Y )

. . . . .

The Arrow actor has two change attribute behaviours and two interpolate behaviours . . . it also needs two 'real' attributes. Let's call the two attributes Target X and Target Y.

Change Target X to Mouse.Position.X -half the length of your arrow* cos(vectorToAngle(Mouse.Position.X-self.Position.X ,Mouse.Position.Y-self.Position.Y ))

Change Target Y to Mouse.Position.Y-half the length of your arrow* sin(vectorToAngle(Mouse.Position.X-self.Position.X ,Mouse.Position.Y-self.Position.Y ))

Interpolate position X to Target X

Interpolate position Y to Target Y

Thanks @socks .I followed the steps u gave.The problem is when I start playing in my creator the bow rotates to the 270 degree and stops.I want my bow to be vertical and could move only 180 degree vertically(It is moving 360 degree now, I dont want that ).Other thing is arrow is spawn only when I released my touch on the bow (if I released the touch on the screen arrow is not spawn). I could not see your example i am using windows creator.Thanks for your help.

These will very likley be caused by the rules you have used, for example do you have a rule that tells your bow actor to rotate like that ?
