Expression Editor - Minimum

JGary321

I am either really bad at understanding or this is a typo??

This is from the wiki, I would think the answer here would be 12....

min

Usage: min(x,y)

Return the smaller value of two numbers or variable values.

Example: min(12,35) = 25

Typo. Difenitely.

That is the all-powerful MIN function! Short for Minimum.

Use it to set a upper limit on something.

You would use it like this:

Let's say in your game you collect coins.
Every time you touch a coin in the game, the game.cointTotal increases by one.
Now let's say your wallet only holds 100 coins.

You COULD add in a Rule that says something like:

Rule
When game.coinTotal < 100
Change Attribute game.coinTotal To: game.coinTotal + 1

Or you COULD add a Rule that says something like this

Rule
When game.coinTotal > 100
Change Attribute game.coinTotal To: 100

The MIN function allows you to simplify and get rid of that extra Rule like this:

When Actor overlaps or collides with Actor of type Coin
Change Attribute game.coinTotal To: min(game.coinTotal+1,100)

The second number represents the upper limit.

It subtle, but getting rid of any extra Rules is very important on a resource-starved device like the iPhone!

You would use MAX in the opposite way to set a bottom limit on something.
Like this:

When my gun has been fired,
Change Attribute game.ammo To: max(game.ammo-1,0)

Hope this helps!

Hehe, yea I was gonna use it to set an upper limit like you said. Then I seen that & I was like what the heck, that's when I tried it & figured I would SMITE the Typo of Injustice. Salad eaters may not feel safe once again!

PS: Sorry you had to do a big write-up FMG. Just sleep well knowing you wrote it in vain... err...sleep well anyways..
