Function to determine angle?

I'm not certain I even need this, but just wondering.

And I hate trig in grade 12 and now I'm paying for it.

I have two z points. one is low, and is high. And, I know how far apart they are.

So how can I figure out in SL the angle from the low to the high?

(something to do with picturing them in a right triangle, and working with opposite/adjacent sides??

I think you need to describe the problem with a little more detail.

Sample heights / distances

Cable car rising on an inclined cable.

Starts at 0 metres height, it's stop is say at 50 metres height, 100 metres away in a straight line.

Want to work out angle of incline. Maybe I don't need it though, might not do anything for me.

A friend made some groovy looking cable cars, and asked if I'd make some scripts to drop in, but this is turning out to be a heavy job. I probably should do this as a vehicle, but if so then I'll have to drop the project as have pre-commitments and no time right now to learn vehicles.

float angleOfIncline(vector p1, vector p2)
{
    vector delta = p2-p1;
    return llAsin(delta.z, llVecMag(delta));
}

Note that if p2 is below p1, this will return a negative angle. You could always use llFabs() if that's not what you want. Also note that the returned angle is in radians, and you should multiply by RAD_TO_DEG if you want to change it to degrees.

Thanks Hewee. Sadly, the function won't compile cause llAsin(float val) only takes 1 value. And I can't figure out how you wanted to join "delta.z, llVecMag(delta)" into one value, though I suspect that's an essential part of the magic. So sorry to bother you, but I wonder if you could just check to see if you made a typo?

Oh. Gosh. Yes. I'm sorry. I use llAtan2() 95% of the time I do trig in LSL, so that's where my head was.

float angleOfIncline(vector p1, vector p2)
{
    vector delta = p2-p1;
    float len = llVecMag(delta);
    if (len < 0.001)
    {
        return 0.0;
    }
    return llAsin(delta.z/len);
}

Hey listen, no, that's great that you can do trig at all. For some reason my mind always soaked up classical Greek and Latin noun declensions like a sponge, but always short-circuited in trig.
