Choosing a player in Game:GetService("Players") with a variable?

Here's your answer

local players = game:GetService("Players")
local player = players:GetPlayerFromCharacter(character)

But I should say, third line of yours is so wrong. You can't use content of variable like .nameplayer, that would check for a player named "nameplayer". You should use :FindFirstChild(nameplayer) or [nameplayer]. Also, nameplayer in your second line is player, not name of player. For name of player you would need players:GetPlayerFromCharacter(character).Name Often, character has same name with player but still, GetPlayerFromCharacter is a good practice.

Yes it would but you would not need the third variable. The second variable would suffice for the player.
