How would I invert the magnitude value?

Hello there!

I’m currently working on a horror game which will have a spirit box like item inside (similar to Phasmophobia). I have got the distance between 2 parts using .Magnitude already but the further away the part is, the bigger the value.

I don’t want this to be the case as I want the value to increase as the parts get closer.

Anyone know how to do this?
Thanks in advance.

You could do a reciprocal function. A number (for example 1) divided by the magnitude.

You can use startMagnitude - currentMagnitude, the value will increase as they get closer

Yep like @Galactiq and @Jxl_s said you can use those formulas:

To make sure you understand what you are doing its best to plot it out on desmos like in this example here which uses @Jxl_s formula which is linear.

For clarification, my suggestion would be a rational function, whereas the suggestion made by @Jxl_s is linear. Just keep those in mind when deciding which is best for your need.

What would the start magnitude be compared to the current magnitude, or is it just flying over my head

The actual mathematical answer to this post is currentMagnitude^-1, because you’re asking for its inversion.

The inverse of currentMagnitude is currentMagnitude^-1 (remember to check if currentMagnitude is zero!), you can then multiply it by a factor if you believe it’s too low.
