Hi,
you might face a small issue with playmaker where if you just created that global event, you need to exit the fsm view, save and renter for the event list to feature you newly created event. Could that be the case?
the event must be global, but I think you got that covered.
Send Remote Event, is really the same thing as Send Event, only that it will be transported over the network. by default, "ALL" is set, so everyone connected in the same room as the player you are sending the event from will receive it. You can choose "Others", so that only other running instances on the network will receive it, etc.
Given your example, it seems tho that this is not what you should use.
Your player and the pick up object are in the same running instance, simply send a regular event from the pick to the player.
bye,
Jean
