Expression Question

[Lukich]

hello. i have a quick question - i'm trying to create an expression that qould rotate my object to 45 degrees or one of it's multipliers. it was fairly easy to create one, which rotates the object every frame:

int(rand($FF)*10)*45

but how would i make the new value being generated every 30 frames, for example? i was experimenting with using modulus, but no luck so far. does anyone know?

thanks a lot,

luka

Have you tried

int(rand($FF%30)*10)*45

hey lukich,

your problem is in the rand.. you are still generating a random number (0 to 1) every frame...

this should get you where you want to be (with the "30" in "$F/30" being how often, in frames, it randomizes)

int(rand(int($F/30))*10)*45

the modulus here is good for creating a loop of the same 30 randomizations over and over again, but will still generate a value every frame.. this is because $FF%30 alone is a different number every frame in itself..

it's alive! my preciousss!!! thanks deecue
