**** DISCLAIMER: I have not began to script this, I just want to be pointed in the right direction. I am NOT looking for anyone to do it for me, just looking for an answer!
So, I want to create a throwable grenade and I don't know how to go about making it arch over to simulate gravity. Should I try to find the arch by doing math.sin and all that or is there any objects I could use. I just want someone to point me in the right direction. All help is good, thanks!
Make an animation using welds and CFrame then use bodyobjects to propel the grenade to the desired location. EDIT1: Then you will need to make something to make the grenade explode obviously.
There is an free model gun that does exactly that. https://www.roblox.com/library/213110580/TMP-v0-0-3 I suggest checking it out and see how they did it. Its not 100% accurate but I guess that leaves up to you to perfect it!
