Convert Velocity to Integer

[Miguelito Shilova]

Hi there. I'm working on a speedometer script and I need to convert the velocity vector to an integer. I'm thinking that I can use llGetVel for starters. SLWiki notes that to get the velocity relative the local frame (the direction the object is pointing), divide the output of this function by that of its rotation.," and provides the folloiwing to do that ...

vector local_vel = llGetVel() / llGetRot();

If I declare an integer 'number', how can I convert 'local_vel' to an integer that represents the speed in the forward/backward direction?

Speed is a scalar quantity, not a vector, so all you need is llVecMag(local_vec), which will give you a float that you may then typecast to an integer as you wish.

Thanks Rolig! Just now a question of syntax. So I would have to declare ...

integer speed;
float local_vec;

and then in the function set it up like ...

speed = llVecMag(local_vec);

Is that correct?

Or if I want to round out the speed integer, could I do this?

speed = llRound(llVecMag(local_vec));

[Rolig Loon]

No, you already have your local_vel, which is a vector.  What you asked about is speed, which is the magnitude of a vector.  And you wanted an integer version of that, so ....

integer Speed = (integer)llVecMag(local_vel);

EDIT:  You type too fast.   Yes, you could typecast with llRound or llFloor too.  :smileywink:

Ah gotcha - and since this converts it to an integer I don't have to worry about rounding it. Cool! Thanks again!

EDIT: haha - yep, I'm a fast typer (apparently not the only one ) I presume since it's typecast as an integer, I would not need to round the value, yes?
