Is it possible to get strings into certain parameters?

For me this would make a lot of sense and prevent extra work.

So would it be possible to create a string where a value in the string is based on a variable that changes so then you could change the location based on a changing sprite name?

So you have different objects - PointA, PointB, PointC.. And you want to get X coordinate from one of these objects, depending on the value in En1ac.point variable?

The closest solution to what you have in your screenshot would be using ternary operator:

(En1ac.point="A" ? PointA.x : En1ac.point="B" ? PointB.x : PointC.x)

.

You can also add all these point objects into a family and pick the family instance.
