Question

JavaScript => public var density: float;
C# => public float density;

Description 描述

The density of the collider used to calculate its mass (when auto mass is enabled)

碰撞器的密度用来它的质量（当自动质量启用）。

When using Rigidbody2D.useAutoMass, increasing the collider density increases its mass - as does increasing its area - as the collider mass is calculated as a product of density and area.

当使用Rigidbody2D.useAutoMass，增加碰撞器的密度会增加它的质量，质量=密度*面积。

Note that by default, Rigidbody2D.useAutoMass is disabled, so the mass of the collider is set directly by Rigidbody2D.mass, and this density value is ignored.

注意，默认，igidbody2D.useAutoMass是禁用的，因此碰撞器的质量是由Rigidbody2D.mass直接设置，该密度值会被忽略。
