Legacy GM [Solved] Player Object shakes when moving vertically in any direction ( jumping/falling )

[XenoMustache]

The object I have created to test player movement appears to 'stutter' when jumping or falling. Disregard the shakiness of the GIF below ( due to low quality recorder ), the GIF still gets the point around, as you can see the obvious shaky movement of the player object as it moves up or down. I have tried changing the view, resizing the room, setting my code to the end step even; none of that seems to help.

Code for player control ( includes physics )

///Control Player Movement
//Get the player's input
key_right = keyboard_check(ord('D'));
key_left = -keyboard_check(ord('A'));
key_jump = keyboard_check_pressed(vk_space);
//React to inputs

friction = 0.5
move = key_left + key_right;
hsp = move * movespeed;
if (vsp < 10) vsp += grav;

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

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

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

Try rounding the y value of the player after moving.

Try rounding the y value of the player after moving.

This does not appear to do anything.

However, rounding the gravity appears to have worked. Thank you for your help, I never would have thought to try rounding it.
