Calc 3rd SimpleVector in a line
« on: April 30, 2013, 12:14:21 pm »
Having a bit of a SimpleVector brain fade lol, trying to calculate the position of the yellow SimpleVector from the first two red SimpleVectors, but the yellow one has to be exactly 500 units away from the middle red SimpleVector.

I could dissect xyx of the vectors and do it the long way but what is the quickest and easiest way of doing this using calcSub etc..?

Code: [Select]
SimpleVector yellowPoint = point2.calcSub(point1);
yellowPoint.normalize(yellowPoint);
yellowVector.scalarMul(500);
