cool script
show user profile  hamid javan
A grate but cool script!

Hi there, recently I read the conversion between s_purs and Grap.
Grap's script was a simple but very useful script and I came to the idea to create a more advanced script based on what Grap had written.
In this script you define a Terrain (no matter the name). This Terrain must be a Mesh and not Poly or...
On top of the Terrain you have the object that want to walk on the terrain. I named it StrayObj
In the Top View turn on the Auto Key and move your StrayObj (make your animation). Just in X and Y position. Don't be worry about the bumps on the terrain, that is what this script should do. Define only the rough path of your animation.
Note that the StrayObj must be in your entire animation above the Terrain because later we want to use the Ray intersect function.
After that run this script. I named it: Walk on Terrain.
A rollout appears.
Define the begin and the end frame of your animation.
Pick your strayObj and your terrain
If you want that StrayObj has the appropriate rotation check the Calculate dir.
If you are satisfied press Calculation
If done close it, but if you want to have some change no mater simply press reset, change your begin and start frame if you want and press calculation again.
I hope that the script is useful for all to you and simple to use.
This is as a gift to Grap, for the help he had done for s_purs.
If anybody has any idea to improve this script, I would appreciate for it.
Simply copy the script and, USE IT.
The script is as follow:

Grap is my personal hero. I'll give the script a look this morning.

I've always said that Grap is the smart one, not that faker who calls himself Garp.

I just tried the script. It seems to work fine. It would be nice if you could make the object follow the angle of the terrain without adding strange rotations to it.

Yeah, you don't see that sort of effort from Garp, that's for sure. Huzzah for Grap!

What? There's a Grap AND a Garp? Confusing times for dyslexics like me.
