change the length of the vector
hi, i tried to change the length of the vector using Vector3.Scale and it seems that it didnt work, here is the code is used:
//CALCULATE THE END POINT OF THE LINE
MicroLabel[i].endPoint=direction+MicroLabel[i].startPoint;
MicroLabel[i].endPoint=Vector3.Scale(MicroLabel[i].endPoint,Vector3(0.2,0.2,0.2));
it messes up the direction. so the question is how to make vector smaller or bigger in length and not mess the direction in the process? i cant seem to figure that out. also i would like to be somehow connected to the camera.distance so that labels and lines stays inside the viewport..any ideas?
thanks!
Based on the nomenclature you are using (start point, end point), it appears you are scaling the wrong value. Scaling the direction is what you should be doing. Something like:
Vector3 scaledDirection =Vector3.Scale(direction,Vector3(0.2,0.2,0.2));
MicroLabel[i].endPoint=scaledDirection+MicroLabel[i].startPoint;
In general, scaling is used on direction vectors rather than vectors which represent points.
I'm afraid that I don't have complete answer for how to scale a line's length to keep it in the view port. There was a case where I needed to scale the width of a LineRenderer based on the camera's distance from it. In that case, I obtained the distance of the camera from the target, then derived a scale based on that distance. E.g. scaleToApply = distanceToTarget * constantScalingFactor. Rudimentary, but it worked in my case.
Also, to scale a vector uniformly, you can simply multiple by the amount. Vector3 scaledDirection = direction * 0.2;
