Variable tutorial...

Can someone point me towards a tutorial that explains how to implement variables?

I've looked through the manual but the explanation seems pretty light. I need a working example so I can see how set them up within the Construct interface.

Thanks all

OK - if no one can point me towards a tutorial, can you help with the following:

Each time my game loads I want the system to choose a random variable (called result), either 1 or 2.

So my event currently looks like:

System > Every tick > System > Set result to int(random(1,2))

How's this? Does this look right?

choose(1,2) would be simpler.

Read the manual for random - 2 will never actually be reached. int(random(1,3)) would give you 1 or 2.

Every tick is every frame, so you are setting a new value potentially 60 times per second

If you just want to set it once each time the layout loads, you would be better off with System->On start of layout

And if you need it set only once per game session, have it initially set to 0 when you declare it and add System->Compare variable result = 0 as an extra condition

Brilliant - thanks for the help. Makes sense
