Control Position / Input Position

How do I send the position input the right values?
I want to control for example only the x - axis of a position.
When I connect a wave with the position input it usually controls x & y.
Would like to control x and y with two separate wave modules for each axis for example.
Using Nodebox 3 on windows.

    Hi Franklin,

    Whenever you have a position value you can break it into separate X and Y values by doing a lookup:

    • Feed position into lookup node set with key set to x to retrieve X value
    • Feed position into lookup node set with key set to y to retrieve Y value

    If you have a single value that you wish to feed into a position port, use make_point. For example, if you want to vary just the X value, feed it into the X port of the make_point node and leave Y. at 0 (or whatever fixed value you want to use). The result will be an (X,0) position that you can feed into any node that needs a position.

    Use a second make_point node to do the same thing with your Y value (leaving X at 0) if you want.

    Does that answer your question? Please feel free to ask followup questions.

    Happy Nodeboxing!

    John
