Documentation Request: Control game loop like pygame

[f-bdolan]

I am interested in building a Gym environment using Ursina in a way like PyGame in this example

This example takes advantage of PyGame's ability to control frame-by-frame with methods like

pygame.init()
pygame.display.init()
pygame.draw.rect()
pygame.event.pump()
pygame.display.update()

It is not clear to me if this is possible in Ursina, or perhaps there is a better way to control the loops beyond app.run().

There is the app.step method wich you can use instead to manually execute the update loop
