Making a scaling system and it scales from both sides (How to implement increment)

Help and Feedback Scripting Support
#1

I am making a game like Mashables. There is a building, rotating, moving, and sizing system you can do with objects in Mashables to make robots. I am trying to replicate this in my game. I have decided to start with the sizing system, and it is acting odd.

Here is the problem: It seems like the block is scaling from both sides, and when I scale it to the edge of the screen, it scales very largely. I want to implement an increment.

local scaleHandle = script.Parent
local block = workspace[script.Parent.Adornee.Name]
scaleHandle.MouseDrag:Connect(function(face, distance)
	if face == Enum.NormalId.Left or face == Enum.NormalId.Right then
		block.Size += Vector3.new(distance, 0, 0)
	end
	if face == Enum.NormalId.Top or face == Enum.NormalId.Bottom then
		block.Size += Vector3.new(0, distance, 0)
	end
	if face == Enum.NormalId.Front or Enum.NormalId.Back then
		block.Size += Vector3.new(0, 0, distance)
	end
end)

Hello? This is a very urgent matter.

#3

You need to also move the position by half the change in size, in the same direction.

#4

Okay, so I’m using this script:

local scaleHandle = script.Parent
local block = workspace[script.Parent.Adornee.Name]
scaleHandle.MouseDrag:Connect(function(face, distance)
	if face == Enum.NormalId.Left or face == Enum.NormalId.Right then
		block.Size += Vector3.new(distance, 0, 0)
		block.Position += Vector3.new(distance / 2, 0, 0)
	end
	if face == Enum.NormalId.Top or face == Enum.NormalId.Bottom then
		block.Size += Vector3.new(0, distance, 0)
		block.Position += Vector3.new(0, distance / 2, 0)
	end
	if face == Enum.NormalId.Front or Enum.NormalId.Back then
		block.Size += Vector3.new(0, 0, distance)
		block.Position += Vector3.new(0, 0, distance / 2)
	end
end)

and it is super buggy.

How could I put an increment into this system?

#8

What type of Instance is scaleHandle?

#9

Its an adornment but that shouldn’t matter to the item it helps to detect if has been clicked on and dragged upon.

#10

I have a question is this being done through the player side, and if so this could be solved quiet easily using the cameras position.

#11

I provided an image:

#12

I can’t find the documentation for the MouseDrag event you’re using anywhere. I need to know if distance is always positive or negative relative to the face, or relative to the part’s local space.

#13

I am using the Handles instance.

#14

Your code seems to assume that the distance will be relative to the part’s CFrame, so pulling out the front face would be a negative distance, and pulling the back face would be a positive. It doesn’t look like that’s correct though.

#15

Also this script can be altered to make a cleaner script and smaller one as well:

local scaleHandle = script.Parent
local block = workspace[script.Parent.Adornee.Name]
local ToAxis = { [Enum.NormalId.Left] = 'X' ; [Enum.NormalId.Right] = 'X';
	[Enum.NormalId.Top] = 'Y';  [Enum.NormalId.Bottom] = 'Y';
	[Enum.NormalId.Front] = 'Z'; [Enum.NormalId.Back] = 'Z' }


scaleHandle.MouseDrag:Connect(function(face, distance)
local Axis = Enum.Axis[ToAxis[face] ]
	block.Size += Vector3.FromAxis(Axis) * distance
	block.Position += Vector3.FromAxis(Axis) * (distance/2)
end)
#16

Okay, so, what am I supposed to do?

#17

You can do this but you need Back to be +z and Front to be -z, which this doesn’t do, same as the original code.

The code looks like this in the script.

#19

Oh I believe you have to put them in brackets or they have to be in the same line which I didn’t do because I wasn’t able to see everything. Also there isn’t any negatives in my script the back on yours has a negative remove that as well.

#20

It is still blue and red. There are still some errors it seems, and I have done everything you suggested.

#21

You don’t need the back and front to be alter they want it to go on both sides they have to be the same on each side but I believe you mean from the position.
