Tweening and Physics

[dangerous10lm]

Guys, I use tween to move a part and touches another part to call a touch function.
But I can’t figure out why roblox physics not working with tween.
Does any solution to solve this? Explain?

I did that test tweening a part to check if touched fired, and worked for me, but seems its dependant:

Part Collision While Tween

Does the parts has CanCollide property enabled? is partB correctly named in workspace? no errors in output? Could you show the entire code? Test this one: local TS = game:GetService("TweenService") local partA = script.Parent local goalCFrame = workspace:WaitForChild("partB").CFrame partA.Touched:Connect(function(otherPart) if otherPart.Name == "partB" then print("Worked") end end) TS:Create(partA, TweenInfo.new(3), {CFrame = goalCFrame}):Play()

And seems this is the answer:

Part Collision While Tween

Tweens (especially those on anchored parts) don’t respect physics so physics-based events (such as .Touched) won’t fire. Try something like the spatial query method workspace:GetPartsInPart in a loop.

Seems you deleted your reply asking for an example. I guess you already found how to use it. But here’s the example:

local TS = game:GetService("TweenService")

local partA = script.Parent
local goalCFrame = workspace:WaitForChild("partB").CFrame

game:GetService("RunService").Heartbeat:Connect(function()
	for _, p in pairs(workspace:GetPartsInPart(workspace.partA)) do
		if p.Name == "partB" then
			warn("touched partB")
		end
	end
end)

task.wait(5)
TS:Create(partA, TweenInfo.new(3), {CFrame = goalCFrame}):Play()

Something I wanna mention, is that when tweening a part and expecting to fire a Touched event of that part, worked pretty fine for me when detecting players with the Tweened part without issues, cause player’s parts are not anchored I guess. But the Tweened part its anchored, and CanCollide is false, and still working pretty good at detecting players without using GetPartsInPart, just Touched event
