simple step by step movement

//simple step by step movement

if keyboard_check_pressed(vk_space)
{speed+=3;} //makes it move
else if speed!=0
{speed+=-1} //slower downer
//note: makes slowdown gradual when button is released!

switch speed

case 0: sprite_index=spr_stap;break;
case 2: sprite_index=spr_slow;break;
case 4: sprite_index=spr_sp1;break;
case 6: sprite_index=spr_zoom;break;
}
//switches the sprites depending upon speed

//special note: this is only a snippet and does not account for other directions or possible other states! it does work however.
