Legacy GM parents

[filipe]

I have just finished following this plat-former tutorial the code works great but i more than one wall
i have try to use the parents thing but the other walls will fall down because of the player code.
here is the tutorial

and the all the code related to that tutorial

///Initialize Variable
grav = 0.2;
hsp = 0;
vsp = 0;
jumpspeed = 7;
movespeed = 4;

///Get the player's input
key_right = keyboard_check(vk_right);
key_left = -keyboard_check(vk_left);
key_jump = keyboard_check_pressed(vk_space);

//React to inputs
move = key_left + key_right;
hsp = move * movespeed;
if (vsp < 10)  vsp += grav;

if (place_meeting(x,y+1,obj_ground))
{
    vsp = key_jump * -jumpspeed
}

//Horizontal Collision
if (place_meeting(x+hsp,y,obj_ground))
{
    while(!place_meeting(x+sign(hsp),y,obj_ground))
     {
     x += sign(hsp);
     }
     hsp = 0;


}
x += hsp;
//Vertical Collision
if (place_meeting(x,y+vsp,obj_ground))
{
    while(!place_meeting(x,y+sign(vsp),obj_ground))
     {
     x += sign(vsp);
     }
     vsp = 0;


}
y += vsp;

Don't use the player object as the parent of the walls. In your code, you are using obj_ground as the object that the player collides with...so use obj_ground as the parent object for walls as well

Dont follow a tutorial. Figure out what the code's intent was and adjust it to retain the intent with appropriate code changes.
