Simulate physics checkbox
This functionality allows to apply the laws of physics to any Actor within the Unreal Engine. When the "Simulating Physics" option is enabled, the Actor adheres to real-world physics, such as gravity, collision, and momentum. This means objects will fall, roll, bounce, and interact with the environment and other objects in a natural and believable manner.
Physics Constraint Component
The Physics Constraint Component offers the ability to define and manage the interactions between different objects in a virtual world. This component acts as an invisible, yet powerful, force that governs how objects move and interact with each other. It allows for the simulation of various mechanical systems, such as hinges, sliders, and springs, enabling objects to behave under constraints like those in the real world. Whether it’s a door swinging on its hinges, a bridge suspended by cables, or a vehicle's suspension system, the Physics Constraint Component provides the necessary framework to make these interactions believable and lifelike.
