table.find returning nil

[loud ravine]

made a simple block placement system, but when trying to delete a block sometimes table.find returns nil even though the instance is in PlacedEntities

local Placement = {Info = {}}
Placement.Info = {
  PlacedEntities = {}
}
function Placement:Place(entity: object, placementPosition: Vector3) --// creates new block in position of mouse
    local newEntity = entity:Clone()
    newEntity.Position = placementPosition
    newEntity.Parent = workspace
    table.insert(self.Info.PlacedEntities, newEntity)
    return newEntity
end

function Placement:Delete(mouseTarget: Instance) --// deletes the block which the mouse is pointed at
    if not mouseTarget then return end
    if not table.find(self.Info.PlacedEntities, mouseTarget) then return end --// checks if target instance is a player placed object
    table.remove(self.Info.PlacedEntities, self.Info.PlacedEntities[mouseTarget])
    mouseTarget:Destroy()
end```

keeps happening to every 1/4th or 1/5th block

oh

nvm

try printing the whole placement tree

then you could find what is going wrong

[loud ravine]

already did and everything shows up fine

the block is in the table and shouldn't cause any problems, but it still refuses to return true with table.find

hm

oh

it was bc

you tried to use instance as a parameter

using instance as a parameter is not a preferred way

but it works

however if you send the instace by remote event or function

the instance id will change

@loud ravine

try using uniqueId

you should care more on specifying and identifying entities

👍 will try it out ty

seems to have fixed the problem, thank you !
