What do you want to achieve? Keep it simple and clear!
I’m trying to script particle life.
But the problem is that it’s giving me nan in bodyvelocity and I don’t know why -
What is the issue? Include screenshots / videos if possible!
And when i was testing my script this happend
no matter what equation i’ll write the result is same (nan)
f means force
PS i tried this equation but it didin’t give me satysfying results
vel2.Velocity = (CFrame.lookAt(prt2.Position,prt.Position).LookVector * f12) / magnitude
What is magnitude?
You can also use the lua debugger to step through your code line-by-line and watch variables as they change to see if they’re what you expect.
magnitude is distnace beetwen prt and prt2
(prt.Position - prt2.Position).Magnitude
It could be possible that you are checking the same part against itself, which would make the magnitude zero. Dividing by zero might be what’s causing the issue.

I don’t think so
Beacuse im adding to velocity so even if it’s zero velocity will be the same
Dividing something by zero in lua gives you inf, but dividing zero by zero gives you nan. Check the position values you are using to construct the CFrame as well, if they are too close to each other they might be causing it too.
saddly i can’t check that out bc whenever i’m trying to get to roblox studio i get this 
Also explorer is empty and all I can see is my script.
I don’t think we can help you much more unless if we see some more of the code that’s causing this issue. Seems like something is going wrong beyond these few lines?
