Once again i’ll point out that providing screenshots and asking a question in the title will not help us help you.
Reproduce on the playground (playground.babylonjs.com), explain exactly what you are doing, and then we might be able to help.
OK , this is playground https://playground.babylonjs.com/#W671DK#6
This is the default arc rotate behavior. When pointer down is triggered it stops and then starts after.
When you are recreating this behavior and detaching the behavior during a pointer down, the pointer up is not triggered in the behavior and is therefor blocking further execution.
work the same.
Note that the solution in #9 is using private variables and is not recommended.
Thank you very much! This way resolve my problem , haha !
