Rotation to point at some vector?

Slowly going crazy here. I want it to rotate an object so it points towards some location.

I put this in a cube:

default
{
    touch_start (integer count)
    {
        vector here = llGetPos();
        vector there = here;
        there.y += 5.0;
        there.y += 5.0;
        
        llRotLookAt(llRotBetween (there, here), 1, 1);
    }
}

When I do this, it barely moves.. Just twitches a little on each axis.

Shouldn't this make the cube point towards x+5, y+5??

The problem is the documentation is a bit ambiguous, I tried to clear up the LSL Portal version.

The two vectors are actually directions and are relative to <0, 0, 0>. The forward direction vector is <1, 0, 0> not <0, 0, 0> which doesn't define a direction at all since it is the origin.

Try doing <1, 0, 0> and <5, 5, 0> which is the same direction as <1, 1, 0> or <.1, .1, 0>.

Also your codes adds 5 to y twice, not to x.

This and other similar questions have been answered many times. Here is how I do it...

there = llGetPos() + <5,5,0>*llGetRot();

I think. i am a little rusty...that's why you should search the forums

I think you'll have more luck with llLookAt(), which will do a lot of the math for you. You give it a point, and it points one of the axes at it. So if you have a vector direction, just add that to llGetPos() and feed it into llLookAt().

llSetRot(llRotBetween(<0.0,0.0,1.0>,llVecNorm(target-llGetPos()))); // point object's Z-axis at target location

/me eeps. Didn't work either way..

Thanks, Guys! Got it all sorted now!
