CollisionDetection in a Placement System?

Asked by

So I'm working on a small placement system, their isn't much to the code. But I am having a hard time figuring out how to detect collision with other parts they they place down. As well as how to make it so they can't place within like 1-2 studs of another part.

Here is my code so far:

local model = workspace.Brick;
game:GetService("RunService").RenderStepped:connect(function()
    if mouse.Target then
        if mouse.Target.Name == "Baseplate" then
            model.CFrame = CFrame.new(mouse.Hit.p.X, mouse.Hit.p.Y, mouse.Hit.p.Z);
        else
            print('not good');
        end
    end
end)

Any help would be appreciated, thanks.

Well, you could get the size X of a part, and the size Z and then make kind of, a little box around the part with adding those to the position of the part. Like,

function detect(part)
local partX = part.Size.X;
local partZ = part.Size.Z;
local pos = part.Position;
local extendX = part.Position.X+part.Size.X;
local extendOtherX = part.Position.X-part.Size.X;
local extendZ = part.Position.Z+part.Size.Z;
local extendOtherZ = part.Position.Z+part.Size.Z;

--// Now you can use this, to create a box just on the border of your part's perimeter. Then you can check if there is a part within that border. Your welcome!
