User tip! Never exceed a value again.

Atlanten

There has been quite a few posts on the forum about values growing too big despite rules and conditions etc.

I thought I'd share a technique that has been really useful for me, and instantly made my projects cleaner and more readable.

It's described in the Wiki, but it's so short that I didn't understand it first. (I'm not used to the math world)

It's the "min" and "max" functions. You can use them to limit values, like this:

If condition is true: change attribute x to min(50,x+1)

So what this does is it chooses whichever number is smaller, 50 or x+1

x will increase by 1 until it reaches 50, then it will just be 50 after that.

You use "max" the same way, except in this case you will get the larger number.

Never exceed a value again...

Hope this helps someone!

that sounds good on paper, but could you apply that as an example of something?

Atlanten

It is basically a rule like this:

if x>y then change x to y

But you don't need to make another rule to add to your long list of rules, you can just put it into the expression.

Here's an example from the forum:

Reading the comments of that post, I realise that's what SMDG is saying, he just didn't explain it!

Ah - I thought I'd read something about min and max somewhere, just couldn't remember.

Nice one Atlanten - I'll go through my games and slip this in!

Thanks a lot!
