Why does the following code experience the listed issues?
The following code is how I handle firing a projectile into a specified direction. The client determines the direction via the mouse location and fires the below event from the server side.
Under normal circumstances, this code works exactly as intended, however, I'm experiencing two notable issues that I need help with that I just can't seem to figure out myself..
1) The most notable issue is that the throwable object hangs up and stops due to interacting with itself. There are very random occurrences where if the projectile is sent at an empty space, there is a slight chance it will "hit" itself, causing the object to freeze in place and not proceed/interact with objects. I thought I handled avoiding this situation in the script but for some reason this still occurs. Could this possibly be due to the speed at which the code runs? I'm up for any advice to further troubleshoot and/or resolve.
2) When hitting another player from the front of their character, we experience the above hang up again. Hitting the player from the back of the character works fine. This is likely related to the above issue.
I appreciate any help you all may be able to provide. Let me know if I need to explain any portions of this code further or give feedback on troubleshooting.
Thanks! Romul

Sounds like your Raycast might be hitting your projectile causing it to hang
The raycast function can have a filter set so you can blacklist or whitelist
Blacklist is anything you dont want to check for so your ray goes through it
or
Whitelist is only check for things in the list
An example on how to hook up this ignore system (Taken from the wiki)
-- Build a "RaycastParams" object
local raycastParams = RaycastParams.new()
raycastParams.FilterType = Enum.RaycastFilterType.Whitelist -- Change this to Blacklist
raycastParams.FilterDescendantsInstances = {workspace.Model} -- enter in your newly cloned part
raycastParams.IgnoreWater = true
-- Cast the ray
local part = workspace.Part
local raycastResult = workspace:Raycast(part.Position, part.CFrame.LookVector*50, raycastParams) -- then add the raycastprams to your ray cast call
-- Interpret the result
if raycastResult then
print("Object/terrain hit:", raycastResult.Instance:GetFullName())
print("Hit position:", raycastResult.Position)
print("Surface normal at the point of intersection:", raycastResult.Normal)
print("Material hit:", raycastResult.Material.Name)
else
print("Nothing was hit!")
end
hope this fixes your problem! :)

I inserted the following code before the service is ran and it is no longer hitting itself. Thanks TGazza!
local raycastParams = RaycastParams.new()
raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
raycastParams.FilterDescendantsInstances = {WEP}
Line 16 in the OG code will also need to state:
local RES = workspace:Raycast(BEG,DIR,raycastParams)
