RaycastResult.Instance type is 'any' instead of 'BasePart'

[bluebxrrybot (blueberry)]

I expect that RaycastResult.Instance will have the type of BasePart, or at least Instance as the name suggests. Instead, the type is any. You can see the issue in the code below.

Reproduction Steps

-- psuedo:
local result = workspace:Raycast(origin, direction, params)
if result then
    result.Instance. --> No autocomplete here
    result. --> Autocomplete for `RaycastResult` here
end

Expected Behavior

RaycastResult.Instance’s type is BasePart.

Actual Behavior

RaycastResult.Instance type is any.

We’ve filed a ticket into our internal database for this issue, and we will update you when we have further information!

Thanks for the report!

May I include the fact the return type for Instance:FindFirstChild() is mismatched too? (supposed to be Instance? but its Instance)

[bluebxrrybot (blueberry)]

Any updates on this? This is still occuring for me.

Would also like an update on this. Looks like a trivial fix.

[bluebxrrybot (blueberry)]

Still says the type is any even though the description suggests the perfect types it could be replaced with!

[bluebxrrybot (blueberry)]

A year later, and the type has only changed to Instance, and not BasePart… could somebody push this fix?

Thanks for the report, and the follow-up! As you have noticed, Raycast does now give the type Instance instead of any, thanks to some of the work that has gone into typing Roblox’s API. For the time being, that’s roughly the best that can be done. It is unfortunately not as simple as editing the type would be if it was purely Luau code (like you get to edit). Nevertheless, there are a few projects underway that are working on systemically fixing issues like this across the API, so keep an eye out for those in the future!
