This is the problem I have, I want to make a Custom Attribute slider that moves one object 1 unit distance along local axis X and another object the same distance in the opposite direction. Basically the objects would swap positions.
By the way, a complication may arise from the fact that the second object itīs parented to the first object.

Now Iīve been squeezing my brain and I havenīt found how to make this, apparently simple thing. Itīs not that I canīt come up with the logical steps for it:

Slider with a value from 0 to 1, create a variable with the input from this slider, letīs call this variable "Bob"
The X position of the first object should be "X position + Bob"
The X Position of the second object should be "X position - 2*Bob" (since this object is a child of the first as the parent moves one unit it has to move back 2 units to end up in the original position of the first object... clear, no?

Quite simple, but I canīt figure out how to get it done. Any ideas?

You could use wire parameters. For this we'll say use Point1, Point2, and Slider. Point1 is the parent of Point2. Wire Slider value to Point1 X_Position with default expression of "value". Then wire Slider value to Point2 X_Position using the expression "-(value * 2)+1".

Make sense?

Iīll try that later, Iīm fuzzy about this part: "Wire Slider value to Point1 X_Position with default expression of "value""... "value" is the name of the slider... value, right?, not a defined variable.

*scratches head again*

I shouldnīt post inmediately after I wake up. :blush: (misc.php?do=getsmilies&wysiwyg=1&forumid=0#)
