Could someone please provide an effiecient stock of rotating an entity around its origin? I found some code in sentry guns plugin, but it is old, inefficient and hard to understand.

pev_avelocity (fakemeta) or EV_VEC_avelocity (engine).

[Kowalsky]

I am really bad in geometric functions, I somehow refuse to understand them... Everything that is connected with angles/velocity is hard to understand. Could you please provide an example and explain it?

[Arkshine]

Just pick up an axis and set some value.

You want probably:

new Float:avelocity[3]
avelocity[1] = someFloatValue; // rotating on y axis
set_pev(entity, pev_avelocity, avelocity);

Shed some light on this function, i can't seem to find anything solid regarding it

[Arkshine]

Nothing to say really.

_velocity is linear
_avelocity is angular. It just rotates around their own axis, like:

[Kowalsky]

So rotating code would be something like

pev( ent, avelocity, aVelo );

aVelo += 10.0; // add 10 degrees???

set_pev( ent, avelocity, aVelo );

If you want to rotate it immediately and only once you need to set its angles instead

So is there a difference between avelocity and lets say ( EV_VEC_ANGLES / pev_angles )?

position:velocity::angles:angular velocity
