an anyone give me an idea of how to make a sphere collision or a Multispheretrace get all the players inside it and add a widget on the screen only on those players that are inside in a multiplayer?
i guess you are trying an area of effect. if so, you can create a struct containing the info you need to share : source, amount etc. then server calculates players in the circle and gives them this struct you just created.
just make a sphere collision with filter characters only… if it overlap any player, call some code to create specific widget
