[Solved]How would I get a previous mouse target when the mouse changes targets?
Okay here is an example to expand on the question. The player moves their mouse over a parta, but then moves it to partb. How would I keep parta as a viable when the player changes their target?
Right now this is my script which isn't working at all
mouse.Move:Connect(function()
if placing then
if plr:FindFirstChild("ObjTarget") == nil then
objTarg = Instance.new("ObjectValue")
objTarg.Value = nil
objTarg.Name = "ObjTarget"
objTarg.Parent = plr
end
wait()
local mseX = mouse.Hit.X
local mseY = mouse.Hit.Y
local mseTarget = mouse.Target
if mseTarget then
for i,v in pairs (tycoon) do
if v == mseTarget then
unitTarget = v
objTarg.Value = unitTarget
end
end
objTarg.Changed:connect(function()
previousTarget = mseTarget
print(previousTarget)
end)
end
end
end)
I am pretty sure I didn't even get close to that script but I have been stumped for the past hour and I'm finally just going to ask.

The short answer is to assign the current target to a previous target variable at the end of the function (but only if the current target is different from the previous target).
You should keep code that you only want to run once outside of event code. For instance, you only need to check if the player has ObjTarget once. You should never set up an event within another event, as you do with objTarg.Changed.
--I assume you have a variety of variables defined here
--Create objTarget if needed
local objTarget = plr:FindFirstChild("ObjTarget")
if not objTarget then
objTarg = Instance.new("ObjectValue")
objTarg.Value = nil
objTarg.Name = "ObjTarget"
objTarg.Parent = plr
end
local previousTarget
function IsValidTarget(target) -- returns true if the player can target the specified 'target' object
for i, v in ipairs(tycoon) do
if v == target then return true end
end
return false
end
mouse.Move:Connect(function()
if not placing then return end -- do nothing if not placing something
local mseX = mouse.Hit.X
local mseY = mouse.Hit.Y
local mseTarget = mouse.Target
if mseTarget and IsValidTarget(target) then
-- Update objTarget
objTarg.Value = mseTarget
-- Update previousTarget
if mseTarget ~= previousTarget then -- if they are the same then the user has simply moved the mouse a bit and hasn't changed targets, so only update previousTarget if they are different
previousTarget = mseTarget
end
end
end)
-- TODO: When you set 'placing = true', you probably want to do "previousTarget = nil", too (if not, be sure that 'previousTarget' is set to nil somewhere)
If you need to access previousTarget outside this script, you'll need to turn it into an ObjectValue just like ObjTarget.
