Get player coords with no decimals

[xoft]

And anyway, what is it that you're trying to do? Wouldn't it be eaiser to check if the distance between the two positions, if it's below a threshold?

local Pos1 = Player1:GetPosition()
local Pos2 = Player2:GetPosition()
if ((Pos1 - Pos2):Length() < 1) then
  -- The positions are less than 1 block apart
end
