📦 Prop

A Prop represents a Dynamic Mesh which can be spawned in the world, can be grabbed around by characters and have physics.

💂Authority

This class can be spawned on both 🟧 Client and 🟦 Server side (if you spawn it on client, it won't be synchronized with other players).

👪Inheritance

This class shares methods and events from Base Entity, Base Actor, Base Paintable.

🎒 Examples

local my_prop = Prop(
  Vector(-900, 185, 215),
  Rotator(0, 90, 90),
  "nanos-world::SM_Crate_07"
)

🛠 Constructors

Default Constructor

local my_prop = Prop(location, rotation, asset, collision_type?, gravity_enabled?, grab_mode?, ccd_mode?)

Type	Name	Default	Description
Vector	location
Rotator	rotation
StaticMesh Reference	asset
CollisionType	collision_type	CollisionType.Auto	Setting CollisionType.Auto will make it automatically switch between Normal and IgnoreOnlyPawn if they are smaller than radius 40 units.
boolean	gravity_enabled	true
GrabMode	grab_mode	GrabMode.Auto	Whether or not the Prop can be grabbed
CCDMode	ccd_mode	CCDMode.Auto	Whether or not the Prop should have CCD enabled (disabling it may cause Props passing through objects if it's kinda small). It's smart to force it disabled on 'visual only' props.

info

If the Prop was spawned by the Client. It will have all interactions disabled (e.g. it will not be able to be grabbed by Characters).

info

Props smaller than radius 40 units or very thin (any side smaller than 20 units) will have CCD (Continuous Collision Detection) enabled automatically to avoid falling through the floor or other objects. This will slightly increase the performance cost of them!
