How to make it so car won't destroy itself?

Help and Feedback Scripting Support

So I have a car in my game, which has crash physics, basically theres a script in some key parts that will :BreakJoints() (simulating a car crash), but, I ran into an issue, the car itself would touch it’s own parts and destroy itself, so I tried to implement a system for it to check two things:

  1. The thing it is hitting is NOT a player (humanoid)
  2. The thing it is hitting is NOT a descendant of itself.

Here is my code:

function onTouched(hit)
	local car = script.Parent.Parent.Parent
	if not hit.Parent:FindFirstChild([[Humanoid]]) and not hit:IsADescendantOf(car) then
			hit:BreakJoints()
		end
	end
connection = script.Parent.Touched:connect(onTouched)

So it fixes it, but it also makes it so it can’t destroy any other cars it touches outside of itself, and any time it touches a part, it gives the error: " IsADescendantOf is not a valid member of Part part it touched"

Can someone please help, thanks!

Still need help with this btw.

For some reason the function is called IsDescendantOf, not IsADescendantOf. Pretty weird, but that should solve the issue.

Quite a common mistake, I’ve done it before myself. IsADescendantOf() isn’t a method of the class Instance. It’s IsDescendantOf(). So your code would look more like this

function onTouched(hit)
	local car = script.Parent.Parent.Parent
	if not hit.Parent:FindFirstChild([[Humanoid]]) and not hit:IsDescendantOf(car) then
			hit:BreakJoints()
		end
	end
connection = script.Parent.Touched:connect(onTouched)
