Raycast failing to hit an object for no noticeable reason

I’m Raycasting from a part that rotates in a random direction to give off a more random feel.

The Raycast is used to grab a position and use it as an end point for a lightning module.

For some reason, “ray” returns as nil.

The “lightningpart” is in an enclosed area with no way for a ray fired from it to technically escape.

There isn’t much else to say, here is the source code:

		local raycastparams = RaycastParams.new()
		raycastparams.FilterType = Enum.RaycastFilterType.Exclude
		raycastparams.FilterDescendantsInstances = {coreFile.core}
		raycastparams.IgnoreWater = true
		coreFile.core.lightningpart.Orientation = Vector3.new(math.random(-360,360),math.random(-360,360),math.random(-360,360))
		local ray = workspace:Raycast(coreFile.core.lightningpart.Position, coreFile.core.lightningpart.CFrame.LookVector,raycastparams)

coreFile is a folder containing a Part with a different Part (lightningpart) parented to said Part.
Both have the same position.

Any help is appreciated.

Best, xarciti

Have you tried multiplying the direction argument on the last line?

#3

Didn’t seem to work. Any other things that might have caused issues?

#4

Have you tested multiple values?
Your other objects may be too far away to be detected if the direction is multiplied by a small number.

I don’t see anything wrong with the RaycastParams. You can create a part to visualize where the ray is being cast.

The ray returns as nil, makes visualizing a bit hard.

#6

try changing the FilterType to Enum.RaycastFilterType.Blacklist

#7

Blacklist was deprecated recently.

#8

Boosting

More info:
The part the ray is being fired from is around 50-900 studs away from everything around it.

Solved. Turns out it was an issue with my lightning module.

Gave Alex the solution because I probably would have not solved the original issue without the knowledge of that multiplier
