Skip animations steps when paused or state missing

Skip animations steps when paused or state missing

Description

The animation does the same steps on each frame. However, some steps (positions, entity creation, etc.) can be skipped when paused or when waiting for the new environment.

This can be useful to allow more time for queued tasks and speed up the loading of the environment.

Goals

• Disable optional steps when paused or waiting for new states.
• Make steps only loop through the entity that need to be check.
• Allocate more time to tasks when paused or waiting for new states.
