Does anyone have an idea what this error is about:

ERROR: Invalid number argument provided. Attempt to set property x to NaN

It appeared after I changed a value I’m multiplying some other values with and using this result as a position in a transition.to action as x goal position. Is the resulted number to small maybe? What does “NaN” mean?

#2

share the piece of code please.

be sure to put a number

x=results\_Of\_Multiply(a,b) --\> local x=tonumber(x) transition.to(obj,{time=100,x=x})

 

#3

NaN means “Not a Number”. Something in your calculation resulted in something that’s not a number.

I would print out the values you are multiplying. It would also help to use the type() function to find out what type of variable Lua thinks each operand is.
