Hello Forum!! Randomized CanCollide?

Assuming we have Part1,Part2 and Part3:

Bricks = {game.Workspace.Part1,game.Workspace.Part2,game.Workspace.Part3} -- We save our parts in a table
RandomBricks = {} -- We create a table that will hold our randomised bricks
Amount = 2 -- We chose the amount of randombricks

for i = 1,Amount do -- We execute the following code the amount of time as we want to have bricks
	local random = math.random(1,#Bricks) -- We chose a random entry in the table
	table.insert(RandomBricks,{Bricks[random]}) -- We save our randomly chosen brick
	table.remove(Bricks,random) -- We remove our randomly chosen brick from the other bricks, so it cannot be picked
end

for _,v in pairs (RandomBricks) do -- For each randomly chosen brick we execute the following code with v being the brick
	v.CanCollide = false -- We set cancollide to false
	table.insert(Bricks, v) -- We put the brick back with all the other bricks
end

RandomBricks = {} -- We empty our table with random bricks so we can safely rerun the code

Above is the most flexible way (I can think of) to do this as you only have to edit the variables Bricks and Amount. You can also replace the table in Variable to game.Workspace.ModelName:GetChildren() if you wanted to use all the children of a model.

If you are simply looking for a way to get 2 randomised numbers that are not the same, this is an easy way to do that:

random1 = math.random(1,3)
repeat random2 = math.random(1,3) until random2 ~= random1
