How do I make arrow fly correctly

Hi all I am making a archer game and have a little problem.

ok you see the template: physics catapult.

edit the animation of the pig by an arrow and delet the useless objects. Then when you will fire the arrow is following a good trajectory but it rotates on it self. I want the tip of the arrow follows its trajectory. Can you tell me how to do that? I hope you understand me. Thranks.

You can just use Bullet for this, with Gravity turned up.

Did you tried? because when i add bullet its just going straight line.

I did try. You have to turn up Gravity on the Bullet. Try Speed:500, Gravity:400.

ITS WORKING !!!!!!!! Thanks my friend <3
