How to make a walljump + move between rooms ?

[dMn420]

I've searched and nothing seemd to work. I will copy all the code, becuse there is no much of it and you can check it yourself if you need.
If you know How can I learn to ad even more mechanics like dash or stamina I will really appreciate it.

I've posted twice becuse I could't edit prevoius post and I have'nt seen this python function.

screen = pygame.display.set_mode(WINDOW_SIZE, 0, 32)  # initiate the window

display = pygame.Surface((300, 200))  # used as the surface for rendering, which is scaled

A dash would simply be the player moving maybe 4-6 times the usual pixels. For Stamina, just have a stamina variable and if it reaches 0, they can't move or if it get's low they move slower (half the usual pixels). One last thing, if you have a player, you should make a player class and give the class all the attributes of a player and functions such as move and draw. Then execute the draw and move functions from the game loop. Hope this helps!

For moving between rooms, I either have the player touch the side of the screen, or touch a door/exit
