Configuring a Dynamic Item Behavior
Specifies whether rotation is allowed for the behavior’s dynamic items.
The relative mass density of the behavior’s dynamic items.
The amount of elasticity applied to collisions for the behavior’s dynamic items.
The linear resistance for the behavior’s dynamic items when two slide against each other.
The linear resistance for the behavior’s dynamic items, which reduces their linear velocity over time.
The charge associated with the item.
A Boolean value indicating whether the item is anchored to its current position.
