help generating completely random numbers

giacomopoppi

Hello everyone, it's been a while since I posted on the forums.
I am having some difficulties with a simple, but unresolvable issue. My game needs to generate constantly random numbers between 1 and 3. This may sound easy but when I try to use the normal method:

every 5 seconds
random(1,3)

I get about 90% of ones and twos (for example), and only a 10% of threes. This is surely not random.

Does anyone have an idea for a work around? maybe using game.time to generate a random number?

Thanks in advance
Giacomo

I just performed the same test (except I made it faster than every 5 seconds) and got 36% ones, 32% twos, and 32% threes.

Ok, ill reexplain the scenario to make it more clear and see if what i am doing is wrong.
I have a car (the actor) which I spawn 7 times in the scene which I then recycle when they go off screen. There are three colours for the cars: one green, one red and one yellow.
I need to assign each car a colour randomly. To do this I do:

change attribute: self.carimage to random (1,3)

when self.carimage is = 1
change image....

when self.carimage is = 2 ...etc

I also say this when I recycle the car:
when car is off screen:
change attribute: self.carimage to random (1,3)

Every time I play the game I get 3 cars one colour, 3 cars another and 1 car for the last colour.



understand?

Perfect, I saw that before but I didn't think it applied in my case. I just saw the video and I think it might work.
Thanks guys

You can always modify what he does in the video. For example, creating say a health bar is the same technique one might use to make a laser and such... Most of the techniques demonstrated in the videos can be modified or ported to other tasks, don't get locked in on the specific example or you'll miss the forest for the trees.

Yes, I think I might have to. It's a shame though... not being able to release a game because I can't change the image of a couple of actors...
Tshirt, will it be quite self-explanitory once tables arrive? (thanks!)
