How do I over write a current ongoing path find (using pathfinding service), whenever a new path find is created.
Example: How do I make it so if the player clicks twice it will cancel the first pathfind.
if Input.UserInputType == Enum.UserInputType.MouseButton1 and not X then
local Path = Pathfinding:CreatePath()
Path:ComputeAsync(RootPart.Position, Mouse.Hit.Position)
local Waypoints = Path:GetWaypoints()
for i, Waypoint in pairs(Waypoints) do
print(Waypoint)
Humanoid:MoveTo(Waypoint.Position)
Humanoid.MoveToFinished:Wait()
end
end
I would think you could use an ID system to describe which pathfinding process is active. Any pathfinding processes with the wrong active id will just break the loop.
-- outside the user input binding,
local activeID -- signifies the current active pathfinding process
-- in the code you posted
activeID = newproxy() -- the active process has changed
local currentID = activeID -- make this the active process
local Path = Pathfinding:CreatePath()
Path:ComputeAsync(RootPart.Position, Mouse.Hit.Position)
local Waypoints = Path:GetWaypoints()
for i, Waypoint in Waypoints do
print(Waypoint)
Humanoid:MoveTo(Waypoint.Position)
Humanoid.MoveToFinished:Wait()
-- if the process doesn't match active process,
if activeID ~= currentID then
break -- stop pathfinding
end
end
In theory, doing another pathfinding process would cancel the first one because the id would be updated and wouldn’t match anymore. Let me know if anything goes wrong!
Edit: alternative method
Another more literal way to go about it is to get the current thread and compare it to the active thread.
-- outside the user input binding,
local activeThread
-- in the code you posted
activeThread = coroutine.running()
local currentThread = activeThread
local Path = Pathfinding:CreatePath()
Path:ComputeAsync(RootPart.Position, Mouse.Hit.Position)
local Waypoints = Path:GetWaypoints()
for i, Waypoint in Waypoints do
print(Waypoint)
Humanoid:MoveTo(Waypoint.Position)
Humanoid.MoveToFinished:Wait()
-- if the process doesn't match active process,
if activeThread ~= currentThread then
break -- stop pathfinding
end
end
