when I shoot a raycast that hits lets say 5 items, how can I find which of them it hit first?
If I am correct raycasts cant hit multiple items, they can only hit one, so unless you are firing multiple raycasts you will only get one item
Just sort them in the order that they were fired in, and then iterate through their results to find an Instance, if there is one, exit the function, something like this:
local t = {} -- to store all our results
local firstIndex; -- this to help find the first index
for i = 1,AmountOFRaysFiring do -- this will iterate 5 times
if not t[i - 1] and not firstIndex then
-- this checks to see if there is no index before the current
-- it also checks if it hasn't been chosen yet
firstIndex = i; -- apply firstIndex variable
-- this means that something hit
end
local result = workspace:Raycast(Position, Direction, Params); -- Cast Ray
if not result then continue end -- ignore if no result
t[i] = result.Instance -- declare index inside table with Instance
-- RaycastResult will always return nil if it hadn't it anything
end
return t[lastIndex] -- return whatever data was collected
-- if it returns nil, nothing has hit at all.
But that depends on how many you are firing, because a ray will only return one result (which means only one instance). Unless you are refering to if something is overlapping, you would have to find the closest object, or pick a random one
Raycasts fire instantly so im guessing the closest you’ll get to figuring out which one hit “first” is which RayResult has the lowest distance.
Raycasts will only hit one item.
