Creature Mod Tutorial 4 - Locomotion 1.0

Hi... I know this is old but I was trying to follow this tutorials but at this step the creature actually don't run, I tryed to enable the mod from steam, just as is given to me, and don't works... I don't know how to make the creature to actually moves by itself, in the tuto says "And that's it!  Now our creature can move around the world.  Right now it looks more like sliding across the world but in our next tutorial, we'll look at how we can setup a stategraph to animate our creature based on it's movement." but the part about " Right now it looks more like sliding across the world" doesn't work help... and thank you!!

(as this is old I will give you a hand, here is the tut04.lua file, the prefab file):

Spoiler

--Here we list any assets required by our prefab.
local assets=
{
    --this is the name of the Spriter file.
    Asset("ANIM", "anim/tut04.zip"),
}

--This function creates a new entity based on a prefab.
local function init_prefab()

    --First we create an entity.
    local inst = CreateEntity()

    --Then we add a transform component se we can place this entity in the world.
    local trans = inst.entity:AddTransform()

    --Then we add an animation component which allows us to animate our entity.
    local anim = inst.entity:AddAnimState()
    
    --The bank name is the name of the Spriter file.
    anim:SetBank("tut04")

    --The build name is the name of the animation folder in spriter.
    anim:SetBuild("tut04")

    --Here we start playing the 'idle' animation and tell it to loop.
    anim:PlayAnimation("idle", true )

    --[NEW] We need to add a 'locomotor' component otherwise our creature can't walk around the world.
    inst:AddComponent("locomotor")

    --[NEW] Here we can tune how fast our creature runs forward.
    inst.components.locomotor.runspeed = 7

    --[NEW] We need to add a 'physics' component for our character to walk through the world.  Lucky for us, this
    --      this is made easy for us by the 'MakeCharacterPhysics' function.  This function sets up physics,
    --      collision tags, collision masks, friction etc.  All we need to give it is a mass and a radius which
    --      in this case we've set to 10 and 0.5.
    MakeCharacterPhysics(inst, 10, .5)

    --[NEW] We need to tell our creature which direction to run in.
    inst.components.locomotor:RunInDirection(270)

    --[NEW] And now we're ready to tell our creature to start running.
    inst.components.locomotor:RunForward()

    --return our new entity so that it can be added to the world.
    return inst
end

--Here we register our new prefab so that it can be used in game.
return Prefab( "monsters/tut04", init_prefab, assets, nil)
