### Deprecated code snippets

Posted:

I found this code snippet and it seems to be deprecated:

and

Is there a way to do this with the latest version of Box2D?

Thanks,

Julian

EDIT: I found a solution:

is pretty much the same as

and

instead of

I found this code snippet and it seems to be deprecated:

Code: Select all

`leftWheel.GetXForm().R.col2.Copy();`

and

Code: Select all

`sidewaysAxis.Multiply(b2Math.b2Dot(velocity,sidewaysAxis));`

Is there a way to do this with the latest version of Box2D?

Thanks,

Julian

EDIT: I found a solution:

Code: Select all

`leftWheel.GetXForm().R.col2.Copy();`

is pretty much the same as

Code: Select all

`double angle = leftWheel.getTransform().getRotation();`

float vX = (float)Math.cos(angle);

float vY = (float)Math.sin(angle);

Vector2 ldirection = new Vector2(vX, vY); //This vector is R.col2

and

Code: Select all

`sidewaysAxis.scl(velocity.x * sidewaysAxis.x + velocity.y * sidewaysAxis.y);`

instead of

Code: Select all

`sidewaysAxis.Multiply(b2Math.b2Dot(velocity,sidewaysAxis));`
