Member Data Documentation

float angleLim = 1.0f

rotation of the joint

angleLim [0.0f - 1.0f]
lock of angle angleLim=1.0f
free of angle angleLim=0.0f
When you set the value which does not belong to [0.0f - 1.0f], it will be truncated

Vector2 axis1Lim = new Vector2(1, 0)

one axis of the joint

axis1 direction and axis2 direction should be orthonormal to each other
axis1Lim = new Vector2(1, 0) means that it lock the x-direction movement
when it is normalized, it means for joint to lock the direction completely

Vector2 axis2Lim = new Vector2(0, 1)

the other axis of the joint

axis2 direction and axis2 direction should be orthonormal to each other
axis2Lim = new Vector2(0, 1) means that it lock the y-direction movement
when it is normalized, it means for joint to the direction completely

float friction = 0.001f

friction of the joint

friction is necessary to stop joint rotation finally, ball joint will continue to rotate if this value is not set properly /remarks>
