📦 Prop

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

info

🟦 Authority: This class can only be spawned on Server.

⏬ Inheritance: This class inherits from Actor and Paintable.

Usage

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

Note

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

Note

Props bigger than radius 200 units will have Grabbable off by default. This can be overridden with :SetGrabbable().
