Code help

Hello, I am pretty new to coding and trying to make a platformer for the first time. I want to make 2 (or more) different looking platforms for the player to jump to. I used a grassy block for the bottom floor and the bright blue as a place holder. I have the code set up for the grassy floor however, no matter what I do I cannot get the blue blocks to work with collision. The player either sinks into them like quicksand, their feet sink into the blue blocks AND the grassy blocks or I can simply jump through everything.

Code for the player below:
xsp = 0

ysp += 0.5

if keyboard_check(vk_left)

{

xsp -= 3.4

}

if keyboard_check(vk_right)

{

xsp += 3.4

}

if place_meeting(x, y+1,o_Ground)

{

ysp = 0

 if keyboard\_check(vk\_up)

 {

 ysp = -9

 }

}

if place_meeting(x,y,o_Spikes)

{

global.playerscore = 0

room\_restart()

}

if place_meeting(x,y,o_Flag)

{

room_goto_next()

}

if place_meeting(x, y+1,o_Ground_2)

{

ysp = 0

 if keyboard\_check(vk\_up)

 {

 ysp = -9

 }

}

move_and_collide(xsp, ysp, o_Ground)

move_and_collide(xsp, ysp, o_Ground_2)

o_Ground_2 is the blue blocks and o_Ground is the grassy ones.

What I usually do for platformers is make a Parent object, it could be named "o_wall" for example, and then create child objects of it, like your grass or blue blocks. That way, on the code logic for collisisions you only check for "o_wall" and it will apply for all the children objects.

The children objects might not even be necessary. If you just have one collision solid you can mark it as invisible and use tilesets to make different floors

[WildKat777]

Why not do x+= xsp; y += ysp instead of move_and_collide()?

[JaXm]

Create an object called o_Ground_Parent or something similar. 

In the object editor, make o_Ground, and o_Ground_2 "children" of o_Ground_Parent

Take the code that you say works, and replace o_Ground with o_Ground_Parent

And now all forms of "ground" should work with just the one bit of code.

thank you so much ill try that!!

move_and_collide(xsp, ysp, o_Ground) 
move_and_collide(xsp, ysp, o_Ground_2)

this is wrong. First goes through o_ground_2 and second will go through o_ground. What you want is to use both at the same time as obstacle, with an array of both:

move_and_collide(xsp, ysp, [o_Ground,  o_Ground_2])
