Unity achieves physical drawing draw Physics Line overview

the implementation of the first edition demo involves three parts: 1. Draw lines and add physical events

(1) Get mouse input

(2) Convert to screen coordinates, then set to Linerender to draw

(3) Create a collider based on the information of the mouse input point

2. Handling of objects and obstacles

(1) Create objects and obstacles, add rigid bodies, and match the relevant collider

(2) To configure the relevant parameters such as gravity

(3) using the PHYSIC2D collision parameters, add the corresponding Addrorce

3. Post-collision processing

(1) Collision treatment of the main object

(2) corresponding UI and level handling
