This platformer video tutorial series teaches you how to create a platformer in simple steps.

For that we use the move_and_collide function that does a lot of work by itself. The idea is to go step by step and create first horizontal movement that is being blocked by walls (instances) and then we use a variable to speed up the horizontal movement (which is being used later for walk, run or other speed values). Lastly we flip the scale of the player if he goes left or right aswell change the image/sprite weather the player moves or is idle.
Thats it!

Tldr this video:
- horizontal movement
- sprite/image setting
