Hello.
I am mostly done with my gun system, but I have one problem.
I don’t have any problems with the spread when the ray DOES hit something, but I can’t figure out how to do my gun spread when the ray, that I cast from the Muzzle of the gun to where the player clicked, DOES NOT hit anything (which means the gun is out of its range since each of my guns can shoot only a certain range).
Right now the code works so that if the ray does not hit any objects this code runs, which just visualizes the bullet tracer based on the maximum range the gun has:
else--THIS CODE PLAYS WHEN THE GUN IS OUT OF RANGE, MEANING THE RAY DID NOT HIT ANYTHING
--WHERE DO I PUT THE SPREAD IN THIS CFrame? MAYBE CALCULATE THE CFrame A DIFFERENT WAY??
CachedBullet.CFrame = CFrame.lookAt(muzzlePos + ((mouseRPos - muzzlePos).Unit * range)/2 , muzzlePos + ((mouseRPos - muzzlePos).Unit * range)) * CFrame.Angles(0, math.rad(90), 0)
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
CachedBullet.Size = Vector3.new(range, 0.15, 0.15)
end
As you can see I don’t know where and how to put the spread in the CFrame calculation if the ray does not hit any object. My spread is just a Vector3.new with randomized numbers. Maybe I should use a totally different approach for calculating out of range bullet tracers?
Here is the full code (By the way I use the PartCache module to help visualize bullet tracers but it’s not important to the problem so just ignore it, I just need the right formula to calculate the CFrame of the part itself)
function ShootBullet(viewRay, muzzle)
local GunName = muzzle.Parent.Name
local GunDataInT = ChosenGunsDataT[GunName]
if GunDataInT.Ammo > 0 then
local range = GunDataInT.Stats.Range
local sNum = GunDataInT.Stats.Spread
math.randomseed(SpreadSeed)
local spread = Vector3.new((math.random(-sNum, sNum)*.01), (math.random(-sNum, sNum)*.01), (math.random(-sNum, sNum)*.01))
SpreadSeed += 1
local mouseRay = workspace:Raycast(viewRay.Origin, viewRay.Direction * 1000)
local CachedBullet = BulletCache:GetPart()
if mouseRay then
local muzzlePos = muzzle.Position
local mouseRPos = mouseRay.Position
local gunRay = workspace:Raycast(muzzlePos, ((mouseRPos - muzzlePos).Unit + spread) * range)
if gunRay then
local gunRayPosition = gunRay.Position
CachedBullet.Size = Vector3.new((muzzlePos - gunRayPosition).Magnitude, 0.15, 0.15)
CachedBullet.CFrame = CFrame.lookAt(muzzlePos + (gunRayPosition - muzzlePos)/2, gunRayPosition) * CFrame.Angles(0, math.rad(90), 0)--Turn it 90 degrees around
else--NEED HELP WITH SPREAD OVER HERE. THIS CODE RUNS WHEN THE GUN IS OUT OF RANGE, MEANING THE RAY DID NOT HIT ANYTHING
--WHERE DO I PUT THE SPREAD IN THIS CFrame? MAYBE CALCULATE THE CFrame A DIFFERENT WAY??
CachedBullet.CFrame = CFrame.lookAt(muzzlePos + ((mouseRPos - muzzlePos).Unit * range)/2 , muzzlePos + ((mouseRPos - muzzlePos).Unit * range)) * CFrame.Angles(0, math.rad(90), 0)-- (spread) Add a spread to the position of where the player clicked since the original mouse position does not account for that
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
CachedBullet.Size = Vector3.new(range, 0.15, 0.15)
end
BulletCache:ReturnPart(CachedBullet1)
end
end
Any help will be appreciated!
