Offset moving

[mtrain]

Is there a chance to somehow edit script for dasher, but replace it with x and y coordinates of frame offset instead of x,y,z coordinates?

void dasher( float Vx, float Vy, float Vz )
{// Dash with desired speed!
    void self = getlocalvar("self");
    int dir = getentityproperty(self,"direction");

    if(dir==0){ // Facing left?
      Vx = -Vx ;
    }
    changeentityproperty(self, "velocity", Vx, Vz, Vy); //Move!
}

The problem is in next:
I try to make moving decorations, like elevator backgrounds, moving buildings on the bike stages. And to achieve moving effect of entity from right to left or from up to down i was adding about 30 frames and each one have its own offset like next:

anim follow1
loop 0
#wait----
delay 10
offset 0 2160

So entity stand on one place but offset is changing and it makes effect of moving, but it looks "laggy" even if to add more frames, but if i add about 100 frames it is difficult to set all frames offsets manually for each frame. So i tried to make next:

anim follow1
loop 0
#wait----
delay 10
offset 0 2160
frame data/chars/misc/72/72_01.gif
#wait----
delay 17
@cmd dasher 0 0 0.513

With this method i can define so many frames as i want and correct the movement by changing dashing speed. With this method i can achieve a smoothness (looks great) but entity moves too. So i cant make it looped, because i need somehow to make entity come back to it previous position.

So, a script that will allow me to change offset of the entity smoothly like dasher script will help me a lot. Or maybe you guys have another solutions?

For this purpose I usually use 2 entities. One is the visible one containing image of wall or background you want to 'animate' and the other is invisible one shooting the former.

Yes shooting, since it's using script, I can control shooting speed and thus control speed background moves. The tough part in doing this is to synch it so when the next background is shot it is stickied to previous one

That's the trick I used in Contra mod in levels where player is moving up or down.

Yes, agree, i make the same yesterday and it is work good enough.
