Hi everyone!

I’m programming a little game (not a simulation so it’s not an exact AI what I need) where the player has to control ships. This game is not real time but round based.  
The tricky part is that there are sea fights where I want to move the ships on curves which represent how the ship will move in this round. Now here comes my problem:

I want to initialize a wind direction (here starts my problem) and compare this with my curve. The curve will get an influence of the wind direction. So I don’t think that I have much problems with the comparison but actually I have a problem declaring and initializing a specific direction :stare:

In addition: My curve is a collection of 100 Points

I hope you guys may help!

Thanks a lot!

Michael
