Hi All!

This is my first full-length script, and i hope that it will prove useful.

Best regards.

Additional Info: 

Update 03-11-2010
Now script warns of the error.


1. Select the desired objects and click on "Get Cars To Array"
Note! These objects should be solid.

2. Select the desired path and click on "Spread Cars"
Note! In addition to the flow of moving objects the script also adds a layer
into the layer manager for easy selection of the flow.

3. To change any settings, select the flow in the layer manager,
enter the desired value, and click the "Reset Cars"

Note! Script warns of the error, but if some actions returns error
i recommend to restart

FP Rand - Random positioning value within the distance between objects in parallel to the flow (in percentage).

WP Rand - Random position value perpendicular to the flow.

4. To replace objects in the flow matrix, select desired objects, press on "Get Cars To Array" then select traffic and press on "Reset Cars"

Flip Follow - Changes the direction of the flow to opposite.

Flip Cars – Reverses the objects in the flow on 180 degrees.

wheel turning alternative...

I noticed something that might help-- though it's true that the script indeed does NOT rotate the wheels geometrically, the same look can be achieved by simply rotating the wheel texture based on the average speed of the vehicles. I did this for a test and it looks quite great :)

My dear friend hanselmoniz!
This script makes the animation of traffic for long-range plan which are not visible to the rotation of the wheels =)

For rotating a wheel use Ant Traffic Simulator

I use this script for vehicles as well as people.... There are only two problems i face with it.. one if you want to merge/delete something it gives errors. Two the vehicles move fine but the wheels do not rotate..So it cannot be used for animations

Awesome script

The Script is very useful. It would be excellent however if we could have rotating wheels too. Just like civil view functionality

Hi !

Nice script thank you ! But I got an error as : "--Unknown property: "addnode" in undefined "

Any idea where it comes from ?

By the way, when I try to use it it also sometimes spread my poly all around and not along the selected spline... Any advice about the pivots pints and where they have to be ? When I reset them (on poly + spline) I got the error I writted first...

Thank you !

Your object must be solid(single mesh) Or...

Hi wearestardust
Your object must be solid(single mesh)
Or use attachment constraint for attached headlights to cars

Hi there, great script, but

Hi there,

great script, but is there a way how I could easily make it compatible with grouped objects?
For example: I need headlights attached to my cars and to get them to move with the cars, I need to either link them to the mesh or group them, but neither of these options work with your script...:(
