Wow. Learning physics is hard. 😅 I've decide to search for an alternative to solution and I came across this tutorial series.
It's incredibly close to what I want but, after watching the entire series, I do predict that will cause problems. I could use some of the ideas I've learnt from the tutorial to fire the grenade with realistic physics and I could even have the player determine the general direction of where the grenade will be thrown. However, I don't think this tutorial will help me to make a player's character( the FPS Controller) accurately predict what's the best angle to throw the grenade at a visible target. I think the series consist of hints to figure it out. I'll try to adapt what I've learnt from this series, integrate it into my project and then get back to you if my suspicions are correct.
