bounds_dist help?

Code:

    Wooden_Floor
        icon = 'turfs.dmi'
        icon_state = "weakfloor"
        var
            health = 5
        Click()
            bounds_dist(usr, src)
            if(usr.hand1 == "")
                if(src.health > 0)
                src.health -= 1
                usr << "The [src]'s health is now [health]"
                view() << "Bang!"
            if(src.health == 0)
                del(src)
                usr << "Your broke [src]!"
                view() << "[usr] has broken [src]!"

Problem description: I have no idea, even after looking at the reference, how I can make it so that if the user is within a few pixels of the floor, they can break it. But when I try to make the bounds_dist into a proc, it throws errors. So really, I need to know how to limit the Click range.

Thanks so much for all the help in advance, because I need it -_-

Kozuma3	if(bounds_dist(usr,src)) I believe you have to use it in an IF statement. ^^

        Click()
            if(bounds_dist(usr,src))
                if(usr.hand1 == "")
                    if(src.health > 0)
                    src.health -= 1
                    usr << "The [src]'s health is now [health]"
                    view() << "Bang!"
                if(src.health == 0)
                    del(src)
                    usr << "Your broke [src]!"
                    view() << "[usr] has broken [src]!"

Alright, now it makes it so that if I touch the border of the floor, it won't break, but far away or on it you can. Do I need

            if(bounds_dist(usr,src) == 10)

or something? Thanks again!

"The value returned by bounds_dist() is the number of pixels that the two objects would have to move closer together (if this is even possible, of course) to be touching but not overlapping.

A return value of 12 for instance means the two objects have a gap of 12 pixels between them.

A return value of 0 means the two objects are not overlapping, but their bounding boxes touch.

A return value of -2 means the two objects are overlapping by 2 pixels; they would have to move 2 pixels apart to separate "

So... Yes, if(bounds_dist(usr,src)==10) would tell you if the bounding boxes are exactly 10 pixels apart. You want to use the <= operator here though, to check if it is within 10 pixels.

Jacob843	Wow! I never would have guessed that I would need the <=; thanks so much for the help!

NNAAAAHH	Not sure if sarcasm or ignorant to DM. Also, I added a href to the <= in my previous post to the referance that explains the operator.

Sep 8 2012, 9:45 am
Jacob843	What? You really did help me...

Sep 8 2012, 9:48 am In response to Jacob843
NNAAAAHH	Lol, not a problem then. You probably should read up on DM, there's probably a lot you don't know about it that you could learn from the referance.

Sep 8 2012, 9:49 am
Jacob843	Well, I was looking at the reference, but for bounds_dist, it never said anything about the if statement. But otherwise, I have used the reference for mostly everything else

When something returns a value, simply calling it doesn't give you that value.

var/a=testproc()//Make variable a equal the return value of proc testproc()
proc/testproc()
    return 2//the return value is 2, variable a will now equal 2
if(testproc)//Checks if there is a return value for the proc testproc()
    ...//If the value isn't FALSE, 0, null, or "" then preform action
if(!testproc)//checks if the inverse of testproc is a valid value
    ...//ect
if(testproc==2)//checks if testproc()'s return value is equal to 2
    ...//if yes, preform action
