Help With Bullet Aiming?

Please note: This may not work, is currently only theory to me. I also do not know what type of gun this is. Does it have a BodyVelocity or something making it go towards where it is facing?

You could try using math.rad() and CFrame.Angles().

For example;

local angle = CFrame.Angles(
	math.rad(math.random(-20,20)/10),
	math.rad(math.random(-20,20)/10),
	math.rad(math.random(-20,20)/10)
)

Bullet.CFrame = CFrame.new(Bullet.Position,mouse.Hit.p)*angle

To break it down:

CFrame.Angles

Changes where the CFrame is facing, is used like this:

CFrameValue * CFrame.Angles(x,y,z)

It's parameters are in radians, which can be converted from conventional angles using math.rad(angle).

math.random()

Pretty self explanatory, the reason I made it go up to 20 then divide by 10 was because math.random cannot work in decimals.

Hope I helped!
