Abrupt end of IK

Hi everyone, today I wanted to make a door with IK animation of the player. Everything works, but I want when we leave the Part the hand smoothly returns to the original position, not as in the video, the animation is abruptly interrupted and the hand returns to the original position.

At the end of the video you can see that when I leave Part the IK animation is abruptly cut off, and I want the arm to smoothly return to its original position.

Help…pls…i don’t know what to do

When the player exists the zone, you can set SmoothTime to like 0.5 seconds. You may have to set IKControl.Enabled = true, iirc it won’t smooth if you disable it.

Oh, I’m sorry, but what target I should select in exit?
Or am I missing something…if so, can you please give this fixed feature?

#5

Target = nil and Enabled = true should do the job, otherwise play around a bit with the variables

#6


Same?

#7

Indeed, because you still have ikControl.Enabled = false there. That’s why it’s abruptly ending.

Remove that line and it should be smoother.

Am I missing something or is this a bug…?

#10

Ah, my bad. You should keep the target to the door handle, but set ikControl.Weight = 0. The ikControl should stay enabled.

When entering the zone, set Weight to 1 or use a distance calculation.
