I want to find out how to make a projectile home in on a target with an "arc".
Basically, I want the projectile to go towards the target in an arc. If the player moves, it should follow them. So far, what I have is the projectile instantiating in front of the player and then going towards the target in a line (using transform.lookat and transform.translate). I have zero clue on where I should go from here.
Green is the player, red is the target.
If you use rigidbodies and physics, there are a couple of solutions here :

Great! These help me with the "arc" part. Now I just need to figure out how to combine both ideas.. thanks!
Ok, I played around with it and it's working a pretty well! I just used the same Transform.Translate/Transform.Lookat stuff I used before and modified the variables in them a bit. It's a bit wonky but acceptable. If anyone has a better way to do this, please show me, but otherwise, thanks alucardj!
you need to learn about the physic engine champ, as ALU explains.
go to UnityGE$$anonymous$$S.com for a vast inrtoduction for beginners
There's a free library for Unity called "iTween" which can calculate splines, including ones that match a ballistic curve (and of course end with a picture-perfect landing on the desired spot).
The first example on its website might that already closely resemble what you're trying to do: http://itween.pixelplacement.com/examples.php
