Hi there , I want to create a sort of match the following game with babylon . But I am encountering a problem with the pointerDragBehavior . The object , cube , starts of okay , but on the second drag down goes even more down and up and down .Please see the playground for reference . The playground I am about to share has a bug which is not there in my editor , it is, a.initFunction in not a function. Please tell me what’s wrong so I can correct it .Thanks.
