Obi Rope Pipe Water Flow Effect

[josemendez]

Hi,

You can change individual particle radii using the particle API:
http://obi.virtualmethodstudio.com/manua...icles.html

Do this using a sine wave, and displace the sine wave along the rope to get the bumps moving. Like this:

Code:

// accumulate time on a member variable:
time += Time.deltaTime * speed;

for (int i = 0; i < rope.solverIndices.Length; ++i)
{
     int solverIndex = rope.solverIndices[i]:
     rope.principalRadii[solverIndex] = Vector3.one * (baseThickness + Mathf.Max(0,Mathf.Sin(i + time)*bumpThickness));
}

Should be pretty easy to do.

let me know if you need help!
