something like ticks per second ?

[xantier]

it is normally 4 ticks per sec (1 tick = 0.25 sec) in OSI. i have checked out the sources a bit but i couldn't actually find something like tickspersecond to control in-game timers properly. where actually are they checked and what is the interval ?

Not entirely sure if it's what you're after, but have you looked at what the following UOX.INI settings do?

CHECKITEMS=1.5
CHECKBOATS=0.75
CHECKNPCAI=1
CHECKSPAWNREGIONS=30

As an example, the lower the CHECKNPCAI value is set to, the more often UOX3 lets the NPC do stuff (like move, or start new actions, select new targets, etc).

no. i will actually code many things based on tick system, even includes the spells.
