Faking a projectile arc

[RoryScanlan]

Basically, is there any way to fake a projectile arc. Using the vectors for origin and target? Or will i need to use complicated maths to work out an actual arc?

Thx

youll have to use maths.

If you are only wanting to figure out the required angle thats required to hit a target given a distance/velocity, its acutally pretty easy.

You can find everything you need here: Projectile motion - Wikipedia

hmm ok thanks reading time, im tryin to hit a moving target lol

Edit i just found this amazing thread

If you dont need a visual line, you need to combine two functions to be able to hit a moving target.

1. http://wiki.unity3d.com/index.php/Calculating_Lead_For_Projectiles
2. That will give you a point ahead of the target, but it doesnt take into account projectile drop. You can calculate that using ‘Angle of reach’ from the first link.

I use these, and it works perfectly.

Thanks for the info ive worked a system out, its not perfect but i can tweak it
