Could someone help me change this script into a "mesh" dropper?
wait(2)
workspace:WaitForChild("PartStorage")
while true do
wait(1.5) -- How long in between drops
local part = Instance.new("Part",workspace.PartStorage)
part.BrickColor=script.Parent.Parent.Parent.DropColor.Value
part.Material=script.Parent.Parent.Parent.MaterialValue.Value
local cash = Instance.new("IntValue",part)
cash.Name = "Cash"
cash.Value = 5 -- How much the drops are worth
part.CFrame = script.Parent.Drop.CFrame - Vector3.new(0,1.4,0)
part.FormFactor = "Custom"
part.Size=Vector3.new(1.2, 1.2, 1.2) -- Size of the drops
part.TopSurface = "Smooth"
part.BottomSurface = "Smooth"
game.Debris:AddItem(part,20) -- How long until the drops expire
end
First and foremost, there's a website specifically for Roblox questions: scriptinghelpers.org. I suggest you use it in the future.
Now that that is out of the way...
It's not very hard to add a mesh to any part. You just have to know what kind of mesh you want, what you want its properties to be, and if applicable, the texture you'll use.
Since meshes are an instance, I'd suggest creating a new mesh instance as a child of your part, and giving it the properties you want. This can be accomplished rather easily with the code below.
local mesh = Instance.new("SpecialMesh", part) -- Create the mesh as a child of 'part'
mesh.MeshType = Enum.MeshType.Sphere -- Sets the mesh's MeshType. If you'd like a mesh type other than a sphere, use the corrosponding MeshType Enum, http://wiki.roblox.com/index.php?title=API:Enum/MeshType
mesh.Scale = Vector3.new(1.2,1.2,1.2) -- this will set scale to 1.2 on all axis
mesh.MeshID = nil -- If you're using a FileMesh, replace nil with the mesh ID, otherwise, you can just remove this line
There are also other properties, such as Offset, TextureID, and VertexColor, which you can read more about on the official wiki page for the SpecialMesh instance.

The button, which I'm trying to use, is in StarterGUI. Don't know if it helps. Fairly new to scripting, however saw another post with something similar and used that code. Here is my code inside the LocalScript:
local MarketplaceService = game:GetService("MarketplaceService")
local player = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local PurchaseEvent = ReplicatedStorage.PurchaseEvent
local productID = 1218445531
script.Parent.MouseButton1Click:Connect(function()
PurchaseEvent:FireServer(productID)
end)
if MarketplaceService:PlayerOwnsAsset(1218445531) then
--Here is where the thing is supposed to happen
end
First you will need to get a reference to the part, one way is to use something like local part = workspace:WaitForChild("PartName")
In order to make it visible, you need to set the transparency to 0. If you dont want the player walking through the part you may also need to turn collisions on with CanColide. Anchoring the part is also recommend to prevent it from falling.
part.Transparency = 0; -- makes it visible
part.CanColide = true; -- makes sure other objects cant go through this
part.Anchored = true; -- prevents the object from falling
There are many ways to make a part move. If the part is supposed to go from one place to another, and only has one destination, a Tween might be useful (see TweenService).
Another way would be with a Heartbeat loop that changes the position each frame (see RunService.Heartbeat). For example,
local keepMoving = true; -- change this to false to stop moving
local RunService = game:GetService("RunService");
local direction = Vector3.new(0, 1, 0); -- change this to anything you want
while (keepMoving) do
local timePassed = RunService.Heartbeat:Wait(); -- wait one frame, roughly 0.016 of a second.
part.Position += direction * timePassed; -- move the part in the direction
end
This would move part up 1 stud every second.
So I have a roblox puzzle game that I have been working on for a while now on based on the arcade classic Q bert where the goal is to change all the colours of the bricks while avoiding enemies and getting a high score but I will be adding some features of my own so it does not get as repetitive such as additional tasks like collecting keys on platforms to unlock the door to the next level and secrets like a diamond that rarely appears once every 10 rounds and collecting one gives the player an extra dude and 10 million points.
This is how the game looks so far https://streamable.com/na46cu
The issue I am having as you can see is that the colours do in fact change but when I jump on it again it changes back to the first colour it changes to which in this case is green but I want it to stay on the first colour and make it so that it does not change until the player jumps on the brick again and later on in the game I want it to become more complex and puzzle like as the game goes on like in this example [https://www.youtube.com/watch?v=9eXJWiNXpOo][2] .
I have tried a few things like adding timers ,debounces and even separate scripts alltogether none of which have worked out for me so far and I of course went out looking for a question from somebody else that had a similar problem but so far I have been struggling to find anybody else that has the same problem.
local module = {} --module for the modulescript and for loop is created
local CollectionService = game:GetService("CollectionService")
for _, part,brick in pairs (CollectionService:GetTagged("blocks"))
do
part.Touched:Connect(function(hit) --Part connects with the touched property to the function with the parameter hit
if (hit.Parent:FindFirstChild("Humanoid"))
then
part.BrickColor = BrickColor.new ("Bright green")
wait (2)
part.BrickColor = BrickColor.new ("Eggplant")
-- local sound = workspace.Sound -- use "local sound = workspace.Sound", if there is already a sound object in the workspace
--sound.SoundId = "rbxassetid://4797903038" --replace quoted text with whatever sound id you need to use
--sound:Play()
end
end)
end
-- end)
--end
return module
I am not the best programmer but I do know the basics of programming and I have tried out various programming languages like Python and c++ all of which are not all that hard to understand once you know the basics of it all but finding out the solution to the problem is the really tricky part and so is bug fixing and troubleshooting.
I do know I could try a simple debounce system but that still does not solve the problem and it only makes it so the code only runs once and slows it down.
I have been asking all over the place for a solution to this problem but I never got an answer to it so I am trying on good old Stackoverflow for once to see if this will be the place where I get the help I need.
this should work, try it
local module = {} --module for the modulescript and for loop is created
local CollectionService = game:GetService("CollectionService")
local DidParts = {} -- Initializing another table to check if the part is already in it
for _, part,brick in pairs(CollectionService:GetTagged("blocks")) do
part.Touched:Connect(function(hit) --Part connects with the touched property to the function with the parameter hit
if hit.Parent:FindFirstChild("Humanoid") then
if table.find(DidParts,part) then
return -- checking if the part isnt in the table if it is then return
end
part.BrickColor = BrickColor.new("Bright green")
wait(2)
part.BrickColor = BrickColor.new("Eggplant")
table.insert(DidParts,part) -- when all the code has finished insert it in the table
-- local sound = workspace.Sound -- use "local sound = workspace.Sound", if there is already a sound object in the workspace
--sound.SoundId = "rbxassetid://4797903038" --replace quoted text with whatever sound id you need to use
--sound:Play()
end
end)
end
-- end)

I am making a roguelike in Love2D as a hobby project. My approach is to try and use as much of the native capabilities of Lua and the Love2D (0.10.1) API as possible, without relying on fancy libraries like middleclass or HUMP, so as to learn more about the language.
After reading PiL's chapters on OOP and seeing the power there, I decided to set up a Mob class (using metamethods to emulate class functionality) that encompasses the players, monsters, and other NPCs (anything that can move). So, far, it's working beautifully, I can create all kinds of instances easily that share methods and all that stuff. But there's a lot of things I don't know how to do, yet, and one of them is holding my prototype up from further progress.
Setting up collision with the map itself wasn't too bad. My maps are tables full of tables full of integers, with 0 being the floor. The game draws "." and "#" and "+" and such to denote various inanimate objects, from each table. Player 1 moves using the numpad, and their position is tracked by dividing their raw pixel position by 32 to create a grid of 32x32 "tiles". Then, inside love.keypressed(key), I have lines like:
if key == "kp8" and currentmap[player1.grid_y - 1][player1.grid_x] == 0 then
player1.grid_y = player1.grid_y - 1
and so on, with elseifs for each key the player can press. This prevents them from walking through anything that isn't an open floor tile in the map itself.
But, I'm trying to implement some kind of "collision detection" to prevent MOBs from walking through each other and to use in writing the rules for combat, and this is trickier. I had a method in place to calculate the distance between mobs, but I'm told this might eventually cause rounding errors, plus it had to be written for each combination of mobs I want to test, individually.
What I'd like to know is: Is there a known (preferably elegant) way to get all instances of a particular class to pass some number of values to a table?
What I'd like to do is "ask" every Mob on a given map where they are, and have them "report" self.grid_x and self.grid_y to another layer of map that's just for tracking mobs (1 if self.is_here is true, 0 if not, or similar), that gets updated every turn. Then, I could implement collision rules based on coordinates being equal, or maybe a foo.is_here flag or something.
I have only vague ideas about how to proceed, however. Any help would be appreciated, including (and maybe especially) feedback as to a better way to do what I'm trying to do. Thanks!
A simple idea is to store "who is here" information for every cell of the field and update this information on every move of every object.
function create_game_field()
-- initialize a table for storing "who is here" information
who_is_here = {}
for y = 1,24 do
who_is_here[y] = {}
for x = 1,38 do
who_is_here[y][x] = 0
end
end
end
function Mob:can_move(dx, dy)
local u = currentmap[self.y + dy][self.x + dx]
local v = who_is_here[self.y + dy][self.x + dx]
if u == 0 and v == 0 then
return true
else
end
end
function Mob:move(dx, dy)
-- update "who is here"
who_is_here[self.y][self.x] = 0
self.x, self.y = self.x + dx, self.y + dy
who_is_here[self.y][self.x] = 1
end
function Mob:who_is_there(dx, dy) -- look who is standing on adjacent cell
return who_is_here[self.y + dy][self.x + dx] -- return mob or nil
end
function Mob:roll_call()
who_is_here[self.y][self.x] = 1
end
Usage example:
-- player1 spawns in at (6,9) on the grid coords
player1 = Mob:spawn(6,9)
-- player1 added to who_is_here
player1:roll_call()
Then, in love.keypressed(key):
if key == "kp8" and player1:can_move(0, -1) then
player1:move(0, -1)
end
There are a few ways you could get all your instances data but one of the simpler ones is probably to have them all be added to a table when they are created. Providing you add the entire table for that instance, all the values will update in the main table because it acts like a collection of pointers.
function mob:new( x, y, type )
self.x = 100
self.y = 200
self.type = type
-- any other declarations you need
table.insert(allMobs, self)
return self
end
Here we insert all the mobs into the table 'allMobs'. Once we have that we can simply iterate through and get all our coordinates.
for i, v in ipairs(allMobs) do
local x, y = v.x, v.y
-- Do whatever you need with the coordinates. Add them to another table, compare
-- them to others, etc.
end
Now we have a table with all our mobs in it and a way to access each of their positions. If you have any further inquiries then let me know.
I've been working with the built-in Resize function in Roblox Studio and have been using it to expand the Top Surface of multiple Parts in order to form a wall-like structure.
The only problem that has arisen when using this method is that the surface of the wall created is not even: Some Parts are higher than others.
I later discovered that this problem is due to the fact that the built-in Resize function only takes integers as it's second parameter (or "expand-by" value). Ideally I need the Parts to have the ability expand by any Real Number.
Are there any alternatives to the built-in Resize function that allow one to resize a Surface by any Real Number?
Yes, this is possible, but it actually requires a custom function to do so. With some fairly basic math we can write a simple function to accomplish such a task:
local Resize
do
local directions = {
[Enum.NormalId.Top] = {Scale=Vector3.new(0,1,0),Position=Vector3.new(0,1,0)},
[Enum.NormalId.Bottom] = {Scale=Vector3.new(0,1,0),Position=Vector3.new(0,-1,0)},
[Enum.NormalId.Right] = {Scale=Vector3.new(1,0,0),Position=Vector3.new(1,0,0)},
[Enum.NormalId.Left] = {Scale=Vector3.new(1,0,0),Position=Vector3.new(-1,0,0)},
[Enum.NormalId.Front] = {Scale=Vector3.new(0,0,1),Position=Vector3.new(0,0,1)},
[Enum.NormalId.Back] = {Scale=Vector3.new(0,0,1),Position=Vector3.new(0,0,-1)},
}
function Resize(p, d, n, c)
local prop = c and 'Position' or 'CFrame'
p.Size = p.Size + directions[d].Scale*n
p[prop] = p[prop] + directions[d].Position*(n/2)
return p.Size, p[prop]
end
end
Resize(workspace.Part, Enum.NormalId.Bottom, 10, false) --Resize workspace.Part downards by 10 studs, ignoring collisions
If you're interested more on how and why this code works the way it does, here's a link to a pastebin that's loaded with comments, which I felt would be rather ugly for the answer here: http://pastebin.com/LYKDWZnt
I am working on a tile-based game. However, due to things such as furniture my map has multiple layers. I have (for the time being) created a square to represent my player. In order to stop my player walking on furniture, I need to make a function that checks for the layer. How do I do that? (Supposing I need to check the layer on the tile to the immediate right of my player)
Pseudo-code ideas:
function checkLayers()
for every layer in map
if layer == "furniturelayer" then
stop player
end
end
end
EDIT: I have found a possible way to do it, but it does not work. I have an array containing the GID of all tiles that are collidable. I am then looping through all layers and checking if the tile has that GID. Code:
function gCheckGID(gMap, gLayer, tileX, tileY)
tilex = gMap.layers[gLayer]:get(tileX, tileY)
return tilex.id
end
function gCheckMovement(gMap, gArray, gTileX, gTileY)
local retVal = true
local layerArray = gMap.layers
local layers = table.getn(layerArray)
for layerCounter = 1, layers, 1 do
currGID = gCheckGID(gMap, layerArray[layerCounter], gTileX, gTileY)
for gidCounter = 1, table.getn(gArray), 1 do
if currGID == gArray[gidCounter] then
retVal = false
break
end
end
end
return retVal
end
I can then use an if statement to get the result and determine whether to move my character or not.
I assume you are using the Tiled library "Simple Tiled Implementation"? If so, I am the author. I have just recently added full collision support to STI using love.physics (Box2D). If you want to create a layer that is entirely collidable (such a sa furniture layer), then all you need to do is add a custom property to your layer in Tiled called "collidable" and set the value to "true".
Tiled now has a collision editor that can be used to add collision data to individual tiles in a tileset. STI also supports this out of the box with no custom properties required.
For more information about STI, check out the LOVE forum thread here.
