What physics model do spinfusor disks use

tribes-ascend

In Tribes: Ascend, I often notice my spinfusor disks seem to go slightly off course over large distances when I'm flying, even though I could have sworn the reticule was over the (immobile) target. I know that disks are not affected by gravity, so there appear to be three other possibilities here:

  • I can't aim.
  • The game adds a slight random shift to the aim at high player velocity.
  • The disk velocity is the sum of instantaneous player velocity and muzzle velocity (that is, physically correct).

Which is it?

Best Answer

None of the above, you're just not accounting for a mechanic in the game called inheritance:

Projectile Inheritance (or simply inheritance) is a mechanic in Tribes: Ascend which causes projectiles you fire to "inherit" some of your current velocity. T:A currently has 50% inheritance on all projectile weapons. This means that if you fire a Spinfusor perpendicular to yourself while traveling at 200 km/h, the shot's end-point will be a trajectory taking into consideration its firing speed, aiming angle, and 100 km/h worth of inheritance in the direction you were moving.
