I'm trying some animations, but i can't make the sprite rest. Any suggestions?

actor={}
actor.x=40
actor.y=30
actor.sprt=0
actor.spd=0.75

function move_d()
    actor.sprt+=0.125
    if actor.sprt>2.9 then
     actor.sprt=1
    end
end

function move_u()
    actor.sprt+=0.125
    if actor.sprt>18.9
    or actor.sprt<17 then
     actor.sprt=17
    end
end

function move_r()
    actor.sprt+=0.125
    if actor.sprt>4.9
    or actor.sprt<3 then
     actor.sprt=3
    end
end

function move_l()
    actor.sprt+=0.125
    if actor.sprt>20.9
    or actor.sprt<19 then
     actor.sprt=19
    end
end

function _update()
    if btn(3) then
        move_d()
        actor.y+=actor.spd
    elseif not btn() then
     actor.sprt=0
    end

    if btn(2) then
        move_u()
        actor.y-=actor.spd
    elseif not btn() then
        actor.sprt=0
    end

    if btn(1) then
        move_r()
        actor.x+=actor.spd
    elseif not btn() then
        actor.sprt=0
    end

    if btn(0) then
        move_l()
        actor.x-=actor.spd
    elseif not btn() then
        actor.sprt=0
    end

end

function _draw()
    cls()
    spr(actor.sprt,actor.x,actor.y)
end

Ways to select objects by pushing a button?

Hi everyone! I know something about coding (very basics stuff) and I'm new to PICO-8.
I'm doing some tests, one of this consist in highlighting an object when the user switch between two objects.
I need some kind of switch, like: when you press 4 the first time highlight X, the second time Y, the following times switch to the other.
This is the code, sorry for bad english:

rect1_x1=5 rect1_y1=120
rect1_x2=20 rect1_y2=110

rect2_x1=5 rect2_y1=5
rect2_x2=20 rect2_y2=15

sex1=-1 sey1=-1
sex2=-1 sey2=-1

function _init()
    cls()
end

function _update()
 cls()
 if btn(4) then
    sex1=rect2_x1-1
    sey1=rect2_y1-1
    sex2=rect2_x2+1
    sey2=rect2_y2+1
 elseif btn(4) then
    sex1=rect1_x1-1
    sey1=rect1_y1-1
    sex2=rect1_x2+1
    sey2=rect1_y2+1
  else end
end

function _draw()

    --background-----------
    rectfill(0,0,127,127,1)

    --select---------------
    rectfill(sex1,sey1,
                                        sex2,sey2,10)

 --1--------------------
    rectfill(rect1_x1,rect1_y1,
                                        rect1_x2,rect1_y2,8)

    --2--------------------
        rectfill(rect2_x1,rect2_y1,
                                        rect2_x2,rect2_y2,8)
end
