Hi,
Following a request in mantis 7973
(http://opensimulator.org/mantis/view.php?id=7973) I did a few changes to
damage, since improvements on physics broke what we had even more.
If llSetDamage() is not used, damage amount is now estimated
from collision relative velocity, and not the penetration depth.
The value reported by physics for this (and collision sounds
intensity) is the projection of the relative velocity on the direction of the
collision plane normal, so it does depend on the collision angle with that
plane normal. This value is then squared so to express a kind of “Energy”.
Objects mass is not taken into consideration
This result value is then scaled to give a little amount of
damage identical to sl, with the difference that moving objects do damage to
avatars not sitting (currently physics doesn’t know about sitting ones).
Physics engines are temperamental things. The collision plane
may not match a real object surface, etc, etc, so results may still seem odd.
To have effective and predictable damage, llSetDamage() should
be used.
Automatic heal is now done on a timed event (heartbeat
actually) so it should work a bit better.
Added OSSL functions:
osSetHealth(key avatar, float health) sets current health (1%
to 100%) (avoided 0 for now because it would not work predictably)
osGetHealRate(key avatar) gets the current automatic healing rate in % per
second
osSetHealRate(key avatar, float healrate) sets the automatic healing rate in %
per second. A value of zero can disable automatic heal, current maximum value
is 100 % per second.
Default heal rate is now around 0.5% per second.
(think we do need to also be able to disable the llSetDamage object autokill,
eventually the death behavior, ?)
The goal is just to improve the current simple health control system, for
simple uses.
Keep in mind the testing nature of opensim master branch.
This may be broken and will change, at least in details, also according to your
feedback
Regards,
Ubit
