How do I spawn a part at the left-most part of the players camera?

#1

I have tried ViewportSize but that didn’t seem to work, any ideas?

#2

Have you tried using ViewportPointToRay?

#3

I tried that and ScreenToWorldPoint and it just keeps putting it in the middle of my screen

The viewportsize divided by 2 is the center of the screen. It should be:

local leftmost = camera.ViewportSize * Vector2.new(0, 0.5)

just tryed your code and it didnt work, still putting the bubble at the center of the screen

#6

It’s probably because whatever Home.CFrame is it’s not at the left of the screen. It also probably is because you need to use ScreenToWorldPoint instead of ViewportPointToRay.

#7

I tried screentoworldpoint as well, but with different code, let me try again thank you

#8

there is no such function ScreenToWorldPoint

#9

Also it cant be the home because its manuiplating the lookvector which is on the Z thats not left and right

#10

Very confusing. What code do you have?

You mentioned the function in this post:

I probably have gotten confused. I will look up the API for this.

#11

the only code i have is the one in the screenshot, i think you got it confused with worldtoscreenpoint

#12

WorldToScreenPoint is what I was looking for. You would need to apply a similar function to it.

#13

Like what function??? Its still not working when im using the ViewportPointToRay so im not sure what to do

#14

It depends on what you want to achieve. If you have the bubble in the left position already, you can use WorldToScreenPoint. If you don’t have it, use ViewportPointToRay`.

Ray.Origin is where the ray starts, so you probably want (ray.Origin + ray.Direction) instead.

#15

If the Ray.Origin is where it hits you shouldnt need to add the direction, also I quickly tried that now I cant see the bubble

#16

If you want to do this, you can just use the ViewportPointToRay() with 0 as both parameters to get the top left corner and then use .Origin for the position.

local cam = workspace.CurrentCamera
local view = cam.ViewportSize
local origin = cam:ViewportPointToRay(
    0,
    0
)

local offset = cam.CFrame * CFrame.new(0, 0, cam.NearPlaneZ) -- dont let the camera clip it

local p = Instance.new("Part")
p.CFrame = offset * cam.CFrame:ToObjectSpace(CFrame.new(origin.Origin)) -- need to get the offset of the camera and the origin position
p.Size = Vector3.new(0.1, 0.1, 0.1)
p.Parent = workspace

this is pretty basic and can be more complex for more accuracy. If it is fine to clip then just use CFrame.new(origin.Origin) with no offset or ObjectSpace

#17

The bubble should be 500 studs to your left, which is probably too far to see. You should decrease the direction value so it’s not as far as 500 studs.

#18

I decreased it to 10 and it still didnt work

#19

Is there seriously no simple way to just get my cameras size as if it were a part??

#20

Try the unitray.Direction, which has a value of 1. Make sure the part is in front of the camera and not behind it.
