Let's say you're trying to find the distance between Player and Object, you could create a variable called Distance.

Distance = int(abs(Player.X-Object.X)+abs(Player.Y-Object.Y))

Then you'd create an event: "System" -> "Compare 2 Values" and then create your comparison however you want (ie. Distance < 5)ScottP2011-10-04 12:50:06

Construct 2 has an expression for this:

distance(x1, y1, x2, y2)

It's the same as it was in Classic btw.

Yeah, you COULD use the distance expression, but where's the fun in that? Don't you know that the more nested parentheses you have, the more impressive your code looks? :p

BTW: I just replaced the parenthetical mess in my project with the distance expression FTW! Thanks!ScottP2011-10-04 13:32:38

Ah, very useful, thanks for that one guys! Can't believe I didn't even think of that or notice the distance() function. I was wondering how to get an object nearest another object and this seems to be the way. :)

Guys, i could only find this Distance() function here, on forums. I used it yesterday when i needed. My question is: where the find built-in C@ functions/methods?

They are all listed in construct when you have to type an expression you should have a window (F4 if it's hidden) with all your layout object, and one of them is "system", if you double click on it you'll see all the system expression available.
Else, you can also read this page of the fabulouse manual
