Make a Platformer with Slopes in 30 seconds

Make a platformer with slopes using the new collision functions in GameMaker as quickly and easily as possible

SARA!! You are amazing!! After losing a day and a half, in this game jam, to fixing broken move and collide your 30 second tutorial SAVES THE DAY!!!

[grsegames]

When u do your tutorial, will u include moving platforms for the player to stand on up and down and left and right?

[Catrantula]

Perfect timing for this. This is just what I was starting to work on for my game remake. Thank you very much for explaining this.

[harrycepeda]

Is possible that you can explain how one way platforms works in this system?

[rangingaway]

I still remember your old tutorial. Brilliant

[bettyanderson]

Dude, thanks for this tutorial ! It help me a lot !

Hey, how to use the new variable with Ledge grab from the other tutorial or will it be a tutorial for later?

[AIG]

Going uphill works but downhill has caused my player to fall through... I use a walk animation code (from your platformer tutorial) the sprite is 32x48. Rectangular collision mask. Not sure if you can help Shaun

Really great tutorial! I'm looking to possibly use this in a platformer test or two; out of curiosity, how might one incorporate semi-solid/one-way platforms using this collision system?

[soubakouh]

I LOVE YOU!! How did it never occur to me to use this function twice separately? ;_;

[quinnkdev]

For some reason, this code doesn't allow my player character to walk back up the slopes. What did I do wrong? :<

[Jordnscot]

Will their be a video on sloped collisions using tile sets?

[spacesandwich]

I tried this code, when going down the slope my character often gets stuck in the slope and when I try to move I get teleported below the ground

Shaun Spalding. Have you find out how to make one-way platforms with move_and_collide?

[weegie]

As a scratch user, just seeing this instead of a basic

repeat (5)
if touching map
change y by (1)
else
stop this script
————————
change y by (-5)

before the horizontal collision code scares me

[Shmorez]

I am having a couple errors. Do you know how I can fix them?
obj_player Event: Step at line 26, 10 : variable _hCol only referenced once
obj_player Event: Step at line 7, 1 : variable slopeOn only referenced once
obj_player Event: Step at line 26, 13 : unassigned variable move_and_collide referenced
obj_player Event: Step at line 35, 13 : unassigned variable move_and_collide referenced

[OTLcrazyboy]

Why do you put the inputs into variables at the start instead of checking them every time instead? Is it more efficient or lower resource consumption?

[deflatedbag]

my god this is awesome
just one question, what's the point of slopeOn? im assuming maybe its a sprint key or something. either way this is incredible!

[Tormentadeplomo]

Now the challenge is to make one way platforms with this.

[IBelieveInCode]

Great. If you can make a platformer (with slopes !) in 30 seconds, you can as well make a AAA game, alone, in one year. Billions of dollars for you :-)
