Moving a model within a grid?
This script is able to move, rotate, and place a model. The item gets placed on a 5x5 block grid.
QUESTION: How will I be able to keep the item within the grid (There are limitations where the item can go); It needs to stay on the grid.
I need the proper way of doing this, I've already tried to make it move only if the mouse's target was the grid; but it was fairly inaccurate as it was slightly still going off the grid.
Localscript:
local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
local PlacedPart = false
local Selected = true
local Rotated = false
local Rotate = 1.57
local Rotation
local yAxis = 0.6
local Enabled = true
local Item = game.Workspace.Model
Mouse.Button1Down:connect(function()
if Enabled and not PlacedPart then
if Item ~= nil then
ClearSelection()
end
end
end)
--[[
function Check()
end
--]]
Mouse.Button2Down:connect(function()
if not Rotated or Rotation == 0 then
Rotation = 1
Rotated = true
Item:SetPrimaryPartCFrame(CFrame.new(Item.PrimaryPart.Position) * CFrame.fromEulerAnglesXYZ(0,Rotate*Rotation,0))
elseif Rotation == 1 then
Rotation = 2
Rotated = true
Item:SetPrimaryPartCFrame(CFrame.new(Item.PrimaryPart.Position) * CFrame.fromEulerAnglesXYZ(0,Rotate*Rotation,0))
elseif Rotation == 2 then
Rotation = 3
Rotated = true
Item:SetPrimaryPartCFrame(CFrame.new(Item.PrimaryPart.Position) * CFrame.fromEulerAnglesXYZ(0,Rotate*Rotation,0))
elseif Rotation == 3 then
Rotation = 0
Item:SetPrimaryPartCFrame(CFrame.new(Item.PrimaryPart.Position) * CFrame.fromEulerAnglesXYZ(0,Rotate*Rotation,0))
end
end)
function ClearSelection()
PlacedPart = false
Selected = false
Rotated = false
Item = nil
end
Mouse.Move:connect(function()
if Selected and not PlacedPart and Enabled then
if Item ~= nil then
if Rotated then -- Mouse.Hit.p.X - Mouse.Hit.p.X%25, Spawn.Position.Y, Mouse.Hit.p.Z - Mouse.Hit.p.Z%25
Item:SetPrimaryPartCFrame(CFrame.new(Mouse.Hit.p.X - Mouse.Hit.p.X%5, yAxis, Mouse.Hit.p.Z - Mouse.Hit.p.Z%5)*CFrame.fromEulerAnglesXYZ(0,Rotate*Rotation,0))
else
Item:SetPrimaryPartCFrame(CFrame.new(Mouse.Hit.p.X - Mouse.Hit.p.X%5, yAxis, Mouse.Hit.p.Z - Mouse.Hit.p.Z%5))
end
end
end
end)

You can utilize the math function min and max here. These functions will return to you either the maximum or minimum of the variant number of arguments given to it.
But we don't want the minimum value or the maximum value, we want a value "clamped" between the two. With a little logic, we get this:
local function clamp(n, low, high)
return math.min(math.max(n, low), high)
end
However, if the high and low values are supplied the wrong way, this would give the wrong answer. You can do a little check to fix this issue, however it is not necessary if it is used correctly.
local function clamp(n, a, b)
local temp = a
a, b = math.min(a, b), math.max(temp, b)
return math.min(math.max(n, a), b)
end
You can use this function to return to you your x and z coordinates clamped between the bounds you want.
Usage Example:
-- Assuming function clamp is defined local highBounds = Vector3.new(100, 0, 100) local lowBounds = Vector3.new(-100, 0, -100) local part = game.Workspace.Part -- Example object local x = clamp(part.Position.X, lowBounds.X, highBounds.X) local y = clamp(part.Position.Y, lowBounds.Y, highBounds.Y) local z = clamp(part.Position.Z, lowBounds.Z, highBounds.Z) part.Position = Vector3.new(x, y, z)
So if desired Part position was Vector3.new(132, -32, -92) then the part would be positioned at Vector3.new(100, 0, -92).
