Classes

Every class a world can hold, with its members. Make one with new("ClassName", parent) or KHIM Engine's Insert Object. Roblox's PascalCase names for the same members also work.

Every object

Member
name, className, parent
find(name), waitFor(name, timeout?), findByClass(className), children(), isA(className)	Finding
clone(), destroy(), destroyAfter(seconds)
tween(goals, time or options)	Parts, UI, Lighting, the camera
addTag, removeTag, hasTag, getTags	Tags
setAttribute, getAttribute, getAttributes, attributes, attributeChanged, getAttributeChangedSignal(name)	Attributes

Parts

Part

position, rotation, transform, size, color, transparency, anchored, canCollide, shape, material, velocity, group, mesh, texture (read-only); touched(part), touchEnded(part); applyImpulse(force), loadAnimation(animation) (a rig).

Spawn - a Part players appear on. MeshPart - a Part showing a 3D model (mesh).

Model, Folder

Groups. A Model moves and copies as one; new("Model") makes one. A Folder keeps things tidy.

Players

Player

name, displayName, userId, team, neutral, position, health, maxHealth, walkSpeed, jumpPower, stats, backpack, character, gui, characterModel; died; teleport(position), damage(amount), kick(reason?), equipTool(tool), unequipTools().

Character

body (a Body), root (a RootPart); moveTo(position), pivotTo(transform).

Body

health, maxHealth, walkSpeed, jumpPower, sitting, state; died, stateChanged(new, old); damage(amount), loadAnimation(animation), getPlayingAnimationTracks(); idleAnimation, walkAnimation, jumpAnimation, fallAnimation, climbAnimation.

RootPart

position, transform, size, velocity.

Tool

enabled, toolTip; activated, equipped, unequipped. Its part named Handle is held.

Team

color, autoAssignable; getPlayers().
