Hello,
I'm making a game were the player uses a sphere to move around a 3d enviroment and find a cone, once the sphere collides with the cone, it will move to a random position, heres the code i made for that:
Positioning the object
Make object cone 2, 200
Position object 2, rnd(2000), 0, rnd(2000)
Collision
[center] If object collision (1,2)>0 then position object 2, rnd(2000), 0, rnd(2000)

Pretty simple, but it's not really so random because after a couple of times of playing it, i've noticed that the cone makes itself go to the same "random" positions everytime. Is there any way I can make it go to different positions?

You need to change the rendomizer's seed value. Try putting RANDOMIZE TIMER() at the top of your code. Since Timer() is pretty much an everchanging value, you should almost always have a different randomizing seed value each time (unless the player plays the game, reboots their computer, and plays again at the exact same milisecond as before, which is nearly impossible)

It would help to put "randomize perftimer()" instead, because when you call rnd() more then once in a row it will sometimes give you the same number if using only "randomize timer()" It won't show up as a command but if you have version 1.066 or up it should compile fine.
