Hi,
there is two way to go about it:
1: using hotween behavior and set it up visually. for this, I guess it's more a question of checking hotween own samples, as it has nothing to do with playmaker, playmaker here would just trigger the hotween you created
2: using hotween to tween a fsm variable ( a vector 3 likely). Is it something you have considered? basically, you tween a vector3, and then use the result with the action "set position" action, everframe and you have your moving object.
bye,
Jean
