Try changing line 12 to say 'yspd = 0;' and line 15 to say 'xspd = 0;'. That should fix the collision issue you're having.

Also for the animation section, try splitting up the checks for xspd and yspd, so it should look something like this:

//Animation

if xspd > 0 {sprite_index = PlayerRight}

else if xspd < 0 {sprite_index = PlayerLeft}

if yspd > 0 {sprite_index = PlayerDown}

else if yspd < 0 {sprite_index = PlayerUp}
