Rotate projectile 180 degrees

Help and Feedback Scripting Support
#1

  1. What do you want to achieve? I’d like for my sword projectile to rotate 180 degrees without breaking the sword projectile.

  2. What is the issue? The sword projectile needs to be flipped 180 degrees.

  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub? I went through so many Dev Forums on the platform during the 2 hours trying to fix it. I tried doing negative LookVectors, negative MousePositions, negative Orientations, etc.

local swordd = sword:Clone()
swordd.Parent = workspace
swordd.Anchored = true
swordd.Transparency = 0
swordd.CFrame = CFrame.new(npc.Torso.Position + Vector3.new(0,3,0))
swordd.CFrame = CFrame.lookAt(swordd.Position, mouseHit)
#2

taking the sword cframe and using the negative of its lookvector to make another cframe should work.

something like this:

local cf = CFrame.lookAt(swordd.Position, mouseHit)
swordd.CFrame = CFrame.lookAt(swordd.Position, swordd.Position - cf.LookVector)
#3

Maybe you could make it face -mouseHit?

local swordd = sword:Clone()
swordd.Parent = workspace
swordd.Anchored = true
swordd.Transparency = 0
swordd.CFrame = CFrame.new(npc.Torso.Position + Vector3.new(0,3,0))
swordd.CFrame = CFrame.lookAt(swordd.Position, -mouseHit) <<< here
#4

tried it, althought it worked sorta, it wasn’t shooting where my mouse was. like it would shoot the same direction but it went above if you shot sorta below, then it would shoot below the mouse if you shot above

#5

Try this instead!

local swordd = sword:Clone()
swordd.Parent = workspace
swordd.Anchored = true
swordd.Transparency = 0
swordd.CFrame = CFrame.new(npc.Torso.Position + Vector3.new(0,3,0), mouseHit)
#6

Thanks, let me try that really quick.

#7

Also, I forgot to add, but mouseHit is the mouse position.

#8

Sorry, it doesn’t seem like it made a difference. image

#9

I knew something like that could happen… Could you show the code that makes it go forward?

Maybe try multiplying the CFrame with a CFrame.Angles value.

Example:

swordd.CFrame *= CFrame.Angles(math.pi/2, 0, 0)

Note that if it doesn’t work try moving the ‘math.pi/2’ part to another section of the CFrame.Angles value

#12

Maybe just multiply it by the negative LookVector over here:

local position,nextPosition = swordd.Position, >>> -swordd.CFrame.LookVector <<< * deltaTime * swordSpeed
#13

I’m also gonna be offline for a long time because school is in like 30 mins and yeah.

#14

done that before, that just makes it go forward, but it doesn’t change the direction

#15

Id try this before you go

local cf = CFrame.lookAt(swordd.Position, mouseHit)
swordd.CFrame = CFrame.lookAt(swordd.Position, swordd.Position - cf.LookVector)
#16

I’ll try when I’m back, I have to get ready for school.

#17

Have you tried this @illuminati6767 ?

#18

(Sorry, look at the post I replied to)

#19

I’ve got to go, I’ll reply in a couple hours.

#20

Exactly! Your sword points correctly with the change in the CFrame.lookAt you did, and with this modification it will then go to the right direction aswell! (i think :p)
