Use align position and create boxs which only it can collide with. Since you seem to be on a 2d grid you can use a aabb system to glitch it back in bounds
You have to keep it placementPart.size.X/2 away from either side. You should pretend that the baseplate is its size - placementPart.Size and then go from there. If you need it to handle rotated objects its a bit more tricky and you would need to essentially determine the smallest axis aligned box that would fit the whole thing for it first then do the same thing with that box.
get the size of the placement pad
get the size of the part
pretend the placement pad size is placementPad.Size - part.Size
check that the mouse point is withing the bounds of the placement parts pretendSize
Note that this would only work on a rectangular baseplate. Any other baseplate shapes would need a different method or an adjustment to this one.
That is essentially it I think, it just does not factor in the size of the piece that is being placed. It will clamp it, but it will allow the middle of the piece to go all the way to the bounds letting the edges go past. To fix that you have to pretend that the base.Size = base.Size - placementPart.Size. Then divide that by 2
They simply forgot to close the last parenthesis. This is a small modification to their code that fixes the out of bounds error you would still get by factoring in the size of the part you are placing in the variable
Here is a simplified version of the code, tell me if it throws another error. One thing to note is that I’m assuming the Sign.PrimaryPart.Size covers the entirety of the sign, otherwise this won’t work.
