Best way to create an infinite runner

Hey,

Does anyone have any advice on the best way to create a complex infinite runner?

I ideally would like to spawn 'stages' of a set width with various sprites in each stage.

As with other infinite runners I would then spawn the next stage as the player reaches the half way point of the previous stage.

I do currently have a system in place but it is pretty long winded.

What is the best way of going about creating a system like this?

Thanks.

Break it down in small chunk and use FUNCTION + Family + Instance Variables, Arrays
