How to give a tension to rope...

[josemendez]

Tension is defined as a force that increases strain. Strain is the ratio between the rope's rest length and its current length:

Code:

float strain = rope.restLength / rope.CalculateLength();

So if you want to increase strain, all you need to do is reduce the rope's rest length so that it is a percentage of the length between the points it is attached to. You can use a cursor to do that, like this:

Code:

cursor.ChangeLength(Vector3.Distance(attachmentA, attachmentB) * 0.6f); //rope is 40% shorter than the distance between its endpoints.
