Hi,

If you have an equation that uses local variables, is it possible to save/load that equation in an array in a useful way?

Let's say you have local variables "A", "B" and "C", and an equation like "lerp(A,B,C)", and you write that equation to an array. Is it possible to configure a condition that loads that array slot equation to variable "D" in a way that Construct will calculate the result of the equation, using your preset local variables, instead of thinking the array slot data is a string?

It's not possible. You will need to parse this string, and if you want to support many different equations or expressions, this will be a very difficult task.

You can try math.js:

mathjs.org
Replace variable names in the string with their values, then feed it to mathjs, and it will calculate the result.

Ok, good to know.

It would have been handy to be able to dynamically choose an equation from an array, but I can work around this limitation.
