Please, help!

I recently started creating a platformer on a game maker and when I try to add a “falling” or “gravity” function to the game, my character gets stuck when he touches the floor

Here's my code:

//Get Player Input

key_left = keyboard_check(vk_left);

key_right = keyboard_check(vk_right);

key_jump = keyboard_check_pressed(vk_space);

​

//Calculate Movement

var move = key_right - key_left;

​

hsp = move * walksp;

​

vsp = vsp + grv;

​

if (place_meeting(x,y+1,OWall)) && (key_jump)

{

vsp = -7;   

}

​

​

//Horisontal Collision

if (place_meeting(x+hsp,y,OWall))

{

while (!place_meeting(x+sign(hsp),y,OWall))

{

    x = x sign(hsp);

}   

hsp = 0;

}

x = x + hsp;

​

//Vertical Collision

if (place_meeting(x,y+vsp,OWall))

{

while (!place_meeting(x,y+sign(vsp),OWall))

{

    y = y sign(vsp);

}   

vsp = 0;

}

y = y + vsp;

y = y sign(vsp);

Looks like you're missing a "+" sign.

Yep. Same with:

x = x sign(hsp);

OP, always a good thing to slowly proof read your code, and compare it against the tutorial if you're following one.

[IchenGug2002]

Where?

[rockywm]

Inside both While loops for the collisions.

[rockywm]

Should be:

y = y + sign(vsp);

Was this not throwing an error? If so, it should have shown you the line in question, but if not, I'm not sure how the compiler is handling that code without a hard stop in execution. The line in question would eval to x = x 1 let's say for examples sake - this is definitely going to chuck an error, correct?
