Gun spread not working properly

Help and Feedback Scripting Support

#1

Hello, this is my first topic post in the DevForum, im quite new and don’t really know much of it.

So, i’m not really good at scripting, however, i can make some decent things. Today i was making this “fish gun” item for one of my admin games, and it has a “triple” mode which fires 3 bullets with spread. However, aiming at the sky doesn’t make the bullets spread, but if you aim at a close object, the spread works.

The small neon spheres are the size of the bullets, they are visible for testing.

I’ve added a comment of where the issue could be with the spread.
Any idea?

Just a few things about posting here.
Don’t use the term ‘bug’ in your tags since that relates to problems with Studio or the website.

Next when you copy/paste a script here you can use 3 backticks before and after the script to properly format it and make it look like code in Studio.

Please post only the section(s) of code dealing with aiming and the spread. I tried CTRL F to find the word spread in your pages of script and gave up looking because I couldn’t find a variable named spread.

Thank you, i have anxiety issues with people replying.

I also had very little luck finding the spread section in the code. But, since this script appears to missing CFrame.Angles or any other rotation based cframe … I could assume:

  • You meant to change the angle of the spread, but instead changed the position.
  • You are using the spread by offsetting the target position to the left or right

When using spread, I would do something like this:

local BulletCFrame = CFrame.new(bullet.Position,Target.Position)
local Spread = 5 -- degrees
BulletPart.CFrame = BulletCFrame.Position * CFrame.Angles(0,math.rad(5),0)

Obviously, not everything is correct. But it is pretty close.

I’ve made a shotgun with spread before, but yeah, i didn’t remember i could use CFrame.Angles.

All i did was change the lines after the comment i put.

water.CFrame = CFrame.lookAt(water.Position, pos) * CFrame.Angles(math.rad(math.random(-5, 5)),math.rad(math.random(-5, 5)),math.rad(math.random(-5, 5)))
water.Velocity = water.CFrame.LookVector * 200
