What do I need to make an app that incorporates physics-based mechanics?

Physics-Based App Development Requirements

Key Components

• Physics Engine: Choose a suitable physics engine (e.g., Box2D, UnityPhysics, Bullet, or Godot's Built-in Physics) based on your requirements.
• Collision Detection: Implement collision detection methods (e.g., AABB, Separating Axis Theorem).
• Rigid Bodies: Define your objects as rigid bodies and decide their properties (mass, friction, elasticity).
• Input Handling: Create an input system to control user interactions within the physics world.
• Environment Setup: Build a simulation environment that supports physics interactions, including gravity and other forces.

Example Code Snippet

// Godot example of a moving body with physics
extends RigidBody2D

func _process(delta):
    if Input.is_action_pressed("move_right"):
        apply_impulse(Vector2.ZERO, Vector2(100, 0))
