Scale/resize Models and Parts and all Descendants

Version 2.0 adds non-uniform scaling by number, Vector2, or Vector3

Currently scaling the following types and properties:

• Model (Size, Position)
• BasePart (Size, Position)
• Attachment (Position) (and thus connected Constraints, e.g. Welds and Joints)
• SpecialMesh (Scale)
• Fire (Size)
• Texture (U/V)
• ParticleEmitter (Size: NumberSequence)
• Explosion (Position, BlastPressure, BlastRadius)
• PointLight (Range)
• Vector3 (Scale, Scale about Point)
• Tool (All Descendants, using Handle as reference)
• Joint (Thanks to @RRainmaker)
• Instances (generic catch-all for e.g. a Folder)

Usage

1. Install npm package

npm i @rbxts/scale-model

2. Import scaleModel, scalePart, scaleExplosion, scaleTool, or scaleInstances

import { scaleModel, scalePart, scaleExplosion, scaleTool, scaleInstances } from '@rbxts/scale-model';

3. Pass a Model, Part, Explosion, Tool, or array of Instances with a scale factor. Scale factor > 1 is bigger, < 1 is smaller

scaleModel(myModel, 1.5);   // All descendants of myModel to 150% size

scalePart(myPart, new Vector3(0.5, 2, 0.5);     // myPart and all descendants to 50% size on XZ and 200% size on Y (tall + skinny)

scaleExplosion(myExplosion, 10);     // myExplosion to 1000% size

scaleTool(myTool, 0.8);     // myTool to 80% size

scaleInstances(myFolder, 0.5, new Vector3(0,0,0));     // all instances in myFolder to 50% size

We need this special api for scaleExplosion since we need to scale it before it is parented.

Custom Scaling Center

You can optionally provide a custom center point in the 3rd parameter, instead of using the Model's PrimaryPart's Position, or the Part's Position.

The scaling of a Model can fail if attempted on a Model that doesn't have a PrimaryPart defined, and no custom center is provided. In that case, a message will be printed in the output.

The scaling of a Tool can fail if attempted on a Tool that doesn't have a Handle defined, and no custom center is provided. In that case, a message will be printed in the output.
