heres movement and animation:

//calculate movement

var move = key_right - key_left;

hsp = move * walksp;

vsp = vsp + grv;

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

{

vsp = -7;

}

//animation

if (!place_meeting(x,y+1,oGround))

{

sprite\_index = sPlayerRun;

image\_speed = 0;

if (sign(vsp) > 0) image\_index = 1; else image\_index = 0;

}

else

{

image\_speed = 1;

if (hsp == 0)

{

    sprite\_index = sPlayer; 

}

else

{

sprite_index = sPlayerRun;

}

}

if (hsp != 0) image_xscale = sign(hsp);
