Purpose of “self” parameter:

• It is required in every method of a class.

• This parameter refers to the specific object that the method operates on.

• It must be present in a method.

• It is automatically assigned to the object that was just created.

Example:

#define the class Emp_class

class Emp_class:

         #defined the init method

         def init(self, name, salary):

              #assign name

              self.name = name

              #assign salary

              self...

I want to ask someone who has experiences in writing physics based simulation software. For context I am building a game engine, and want to implement physics simulation. There are a few approaches that I managed to find, but would like to know what are other approaches to doing physics simulation entry points from scenes, would you be able to visually draw me a few approaches (like 3 approaces)? When I say entry point to the actual physics simulation. An example of this is when the user presses the play button in the editor, it starts and initiates the physics system. Applying all of the global physics settings parameters that gets applied to that scene. Here is the use-case, I am looking for. If you have two scenes, and select scene 1. You press the play button. The physics simulation starts. When that physics simulation starts, you are also having to update the physics through some physics dedicated delta time because physics needs to happen faster update frequency. To elaborate,…
