Moving objects using VEX

[victorrijo]

Hi everyone,

 

I'm trying to make something similar to this using VEX.  

 

For some reason my cube its "jumping" every time it changes direction. (see attached video)

Here's the code I wrote so far:

 

f@random = random(@Time);
@random = fit01(@random, 0, 3);


//moves in X
if (@random < 0.5){
    @P[0] += (@Frame / 15);
}
//moves in Y
else if (@random > 0.5 & @random < 1.5){
   @P[1] += (@Frame / 15);
}
//moves in Z
else{
   @P[2] += (@Frame / 15);
}

I tried doing the same using VOP (see attachment) but I'm getting the same results.

Because each position calculation is done from scratch each frame. Take your wrangle node and paste it inside a Solver Sop connected to 'previous frame'. I think that will be what you are after.

 

Cheers,

Thanks, the solver sop worked great. I changed the vex code as well. 

 

f@random = random(@Frame);
@random = rint(fit01(@random, 0, 6));


if (@random == 0){
    @P[0] += 0.1;
}

else if (@random == 1){
   @P[1] += 0.1;
}

else if (@random == 2){
   @P[2] += 0.1;
}

else if (@random == 3){
    @P[0] -= 0.1;
}
else if (@random == 4){
    @P[1] -= 0.1;
}
else {
    @P[2] -= 0.1;
}
