Grenade impact - kinetics way off
Closed, ResolvedPublic


Throwing grenades (any type) at vehicles will move the vehicle upon impact, sometimes several feet!

So hand grenades impact as though they weigh 200-1000 pounds. This may also be why they hardly ever bounce, even with flat trajectories.

I just tried it with current alpha version and it isn't as prominent (not "way off"). It seems more evident on damaged vehicles.

If a grenade detonates next to an empty hunter (all passenger vehicles seem to work) and damages it, the next grenade you throw at it will jar the vehicle upon impact.. smoke grenades, frag grenades... haven't tried any other thrown objects.

When I made this thread the impact was enough to move a vehicle several feet however now it only shakes the vehicle. Regardless, a 1 pound objects impact should not move a multi-ton armored vehicle at all when thrown by a soldier.

@Astaroth it's fixed. Ticket can be closed.
