Can you do CurrentPosition.Changed()?

Help and Feedback Scripting Support
#1

I want a function to play when the PrismaticContraint reaches a certain position I tried to use a while loop before but even when the correct number is displayed it still loops without doing what I want

#2

you could try like

PrismaticConstraint:GetPropertyChangedSignal('CurrentPosition'):Connect(function()
if PrismaticConstraint.CurrentPosition >= desiredposition then
loop:Disconnect()
end
end)

this script assumes that the other loop is hooked to like heartbeat or renderstepped and not a while wait

#3

The constraint is an elevator and I can’t rely all on wait to do things

#4

If you can show us your other script we can better help you.

@hockeylover29’s solution will work if you’re using any form of loop, just replace loop:disconnect() with a flag/boolean e.g. active = false and where your loop is functioning, break it at ‘not active’.

Similarly, this could also be used to set the constraint’s speed to 0 when the position is reached.
