GetPartsInPart() loop not working as expected

I’ve probably said this so many times but, I wanna make an ability that releases a sphere, and the parts that hit it, if it’s of a character’s then it detects wether the part is a descendant of NPC or Players folder in workspace. Similarly, if it’s a descendant of the Players folder then it’s of a player’s, the same goes for NPCs. But, it’s not working as I expected it would. If the player is a little far from npcs or players(but the npc or player is still touching the sphere when it’s done tweening), then only the player would go invisible, and sometimes a few seconds later the other players or npcs touching the sphere even after it gets destroyed goes invisible.

Let me show you what I mean: https://gyazo.com/b5c62df6df5997316419199060799401

If the player is near: https://gyazo.com/abb2d6753f2d6d768cd99a8982f4b808

sorry if I had bad explaination I’m not good at explaining

Can you please provide your code…??

Oh! Sorry, I thought I already pasted it in xD

You are only determining the players touching the part at the very start. You should also add a .Touched event to the script!

so from looking at ur issue i remembered that region3 (which is now technically deprecated) and getpartsinpart have the same issue. if u try to find multiple entities inside of the said part it will only find the first entity, the rest would be ignored. U should instead use touched event and disconnect it when it hits anything and get all of the touching parts. u could also go a bit more wonky and make a table of every npc/player it hit and loop through and delete the said player/npc if it finds it in the loop

obviously with the table method u arent required to use touched but its ur call

so how would I make it like expected then?

I converted it into gettouchingparts and touched event.

Although, another problem occured.

It detects if it’s an npc or player’s bodypart and then only sets 1 body part transparency into 0. and also if I’m in the sphere with the npc then i go invisible seconds after that 1 body part became invisible and visible again.
