what exactly does the elasticity tag do? I know elasticity is the ability of an object to retain its shape but how does that affect anything in the game? And I dont recall ever seeing a weapon with a lower or higher value than .75

It makes the projectile bounce. However, it can also be used to make the weapons more like tanks in RA/TD and make the weapons hit where the unit was rather than automatically home in on them. This was used to make the Nod Artillery useless against moving targets.

but on the disk weapon elasticity is not changed so why even include the tag for that purpose when the bouncy=yes tag is present?

Oh and for the second half of your answer: what makes shells tend to "miss" their target, a lower value or higher value?

Lower. Use Elasticity=0.0
The Bounces tag is used for bouncing weapons but to my knowledge Elasticity is too.

Elasticity defines how much an object bounces. Tire debris bounce more than disc-thrower grenades.
With a higher Elasticity they simply bounce more.
And to have them even Bounce you need the Bouncy=yes tag, else Elasticity is useless.

I have studied this a bit, it seems odd that the elasticity can be set to something between 0.0 and 1.0, and if elasticity is 0.75 (the default), the effect is neutral. It would make more sense if it was 0.5. Why is this?

I think .75 is an actual value used in physics that creates a neutral value. I wonder what would happen if you put a number in like 2 or -1 for elasticity.

It might crash, TS rules ini recommends to use values between 0.0 and 1.0.

Hey Check this out, negative elasticity does some crazy things with weapons. Apparently when the value is negative the projectile seems to go under the map a certain depth then detonate just behind where the projectile went under the ground. You could probably make a good suicide weapon if the damage was done high enough with a high enough blast radius. Anyway I found that lowering the elasticity (including negatives) makes the projectile behave like a rock while raising it makes it behave like a bouncy ball. I raised the elasticity to 2.0 and the projectile bounced more than 1/2 way across a 90x90 map! At 20 it just disappeared from the map after a few frames of airtime. I actually think it went above the max speed of 100 at one point.

That's odd...that is very odd...

I think what's happening here is that since elasticity in TS dictates how far an object bounces and how fast it bounces (I think its exponentially relative to the speed of the projectile) perhaps that is exactly what is happening JUST UNDER THE MAP! Think about it, maybe the disc is bouncing underground! But since there is no -z (i think) axis under the map everything gets distorted. I'm not sure if the gravity settings for TS (its 1-6 whatever the hell units they used) apply when something somehow gets under a map.
But I dont know how to explain how the lighting ended up there. Unless, its an optical illusion like in the "Large Ion Cannon" test I did with a multimissile. The beam appeared to spawn adjcent to the rings when it was actually on top of it!

Lets call banshee over here and see if he knows. Hell we must summon the grand council of modders!!!!!!
I'm also going to do some experiments with gravity settings and see what I get.

first: yes a -z axis exist. It is often used to adjust animations on buildings.
Just think about underground units. They use -z too.
second: the lighting is very normal. it's just at the place where the projectile exploded in the underground. The "distorted" place is always along the vertical view-axis showing that the projectile exploded ca 8 height steps under the scorched earth. So you just found out how to make an underground weapon.
Also here, look at underground units. They drive always to a cell under the actual target and then drive straight upwards about 2 or 3 cells.

Something you can test is, if you can make a weapon able to shoot at those underground driving vehicles using an underground weapon.

so are we saying we have subterrain weapons? like a subterrain missile is possible?

the thing is though, that when the disk thrower has a target the disks usually go to the unit with no problem. So instead of a disk bouncing to a unit they just land on top of a vehicle. However if the disk misses the target it goes underground
