i have something really simple all i need to do is set color of this model to red/green depending on whether it can be placed
here is my script
local PhysicsService = game:GetService("PhysicsService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local events = ReplicatedStorage:WaitForChild("Events")
local towers = ReplicatedStorage:WaitForChild("Towers")
local spawnTowerEvent = events:WaitForChild("SpawnTower")
local camera = workspace.CurrentCamera
local gui = script.Parent
local towerToSpawn = nil
local canPlace = false
local function MouseRaycast(blacklist)
local mousePosition = UserInputService:GetMouseLocation()
local mouseRay = camera:ViewportPointToRay(mousePosition.X, mousePosition.Y)
local raycastParams = RaycastParams.new()
raycastParams.FilterType = Enum.RaycastFilterType.Blacklist
raycastParams.FilterDescendantsInstances = blacklist
local raycastResult = workspace:Raycast(mouseRay.Origin, mouseRay.Direction * 1000, raycastParams)
return raycastResult
end
local function RemovrPlaceholderTower()
if towerToSpawn then
towerToSpawn:Destroy()
end
end
local function AddPlaceholderTower(name)
local towerExists = towers:FindFirstChild(name)
if towerExists then
towerToSpawn = towerExists:Clone()
towerToSpawn.Parent = workspace.Towers
for i, object in ipairs(towerToSpawn:GetDescendants()) do
if object:IsA("BasePart") then
PhysicsService:SetPartCollisionGroup(object, "Towers")
end
end
end
end
gui["main-game"].Frame.Frame.Spawn.Activated:Connect(function()
AddPlaceholderTower("Pistol")
end)
UserInputService.InputBegan:Connect(function(input, processed)
if processed then
return
end
if input.UserInputType == Enum.UserInputType.MouseButton1 then
if canPlace then
spawnTowerEvent:FireServer(towerToSpawn.Name, towerToSpawn.PrimaryPart.CFrame)
RemovrPlaceholderTower()
end
end
end)
RunService.RenderStepped:Connect(function()
if towerToSpawn then
local child = towerToSpawn:GetChildren()
local result = MouseRaycast({towerToSpawn})
if result and result.Instance then
if result.Instance.Parent.Name == "TowerArea" then
canPlace = true
child.BrickColor = Color3.new(1,0,0)
else
canPlace = false
end
local x = result.Position.X
local y = result.Position.Y + towerToSpawn.Humanoid.HipHeight + 1.95 + (towerToSpawn.PrimaryPart.Size.Y / 2)
local z = result.Position.Z
local cFrame = CFrame.new(x,y,z)
towerToSpawn:SetPrimaryPartCFrame(cFrame)
end
end
end)
