Solved Helicopter in the background

[Crimsondeath]

Hi again.
It's possible to stick an entity to the background and make it moves only in it? I need it for this helicopter enemy:

It's also posible that the helicopter balance a little, on the direction he is moving?

Here is the full Helicopter Code:

Spoiler: Helicopter

"Heli_Propeller" and "Heli_target" are separated entities:

the onmovexscript code:

void main(){
    void self = getlocalvar("self");
    void propeller = getentityvar(self, 1);
    float velocity = getentityproperty(self, "xdir");

    if(velocity < 0){
      changeentityproperty(propeller, openborconstant("ANI_FOLLOW1"), 1);
    }

    if(velocity > 0){
        changeentityproperty(propeller, openborconstant("ANI_FOLLOW2"), 1);
    }
}

Thanks

Yeah, you can limit his Z position using script.
If I am not mistaken, I am using this code:

void main()
{ // Limits z movement to certain z coords
    void self = getlocalvar("self");
    int z = getentityproperty(self,"z"); //Get character's z coordinate

    if(z != 200){ // Reached z limit
      changeentityproperty(self, "position", NULL(), 200);
      changeentityproperty(self, "velocity", NULL(), 0);
    }
}

About to make him to balance, you can add a walk and a backwalk animations, and use drawmethod rotate - So it will lean to the right when in the WALK animation and lean to the left in the BACKWALK animation.

This is how I did:
drawmethod rotate 2
drawmethod fliprotate 1

I used the code as "onmovezscript" instead of "onmovexscript" and works great .

Thanks again @O Ilusionista .
