Hotfix for "Spikey Plants" not firing any of their "Thistle" weapons.

Apparently, for some obscure reason, setting the cvars.txt "kPhysicsDamping" parameter to 1 cause them to no longer fire projectiles weapons...

"kPhysicsDamping" was set to 0.999. Should be pretty close to absolute momentum conservation...

Initial Release

Change the following cvars.txt parameters:

kPhysicsDamping = 1.000

This cause the momentum of any object to be conserved as long as no force act upon it. Exactly like in real space...
