Overlays?

[PvtRyan]

I recently send an email to Rick Ellis, and received an answer today, now I've heard stuff about overlays a few times but still don't really know what they are (and I've used the search)

It's this email:

Yes, you can use overlays for this. I'm not sure what you mean when you
refer to the "rigidness of the suspension".

Hi Rick,

A quick question if you have the time for it:
Is there a way with Source to more or less simulate tank tracks
correctly?
And I mean in the way that they will 'bend' around terrain and certain
small obstacles and also accordingly to the rigidness of the suspension.
Is this perhaps possible with the same technology that does the 'rope
swinging'?

Well, thanks for your time, keep up the great work with the game!

With the rigidness of the suspension I meant the wheels of the tank themselves reacting to the ground based on how tight their suspension is and the tracks curving around the wheels.

Anyone cares to explain please?

I think he thought you were talking about tracks a tank would leave on the ground, instead of the tank "treads".

Don't really know about overlay's though.

AFAIK overlays are kind of like decals, they have a trasparent part so you can make footprints and stuff (someone tell me if I'm wrong). I'm pretty sure he thought you meant the tracks in the dirt that a tank would leave rather than the 'treads'. But I think he would have said yes to the treads question, I'm pretty sure the physics would handle that fine.

Yup the term overlays in source has been mentioned concerning the next evolution of decales.

They can wrap arround surfaces so you dont get that thing where bullet holes come off the sides of objects... If you get what I mean lol. :rolling:

Yup, think he thought you were talking about treadmarks.

Hmm used the wrong words I guess....
