Regex Help

I am aweful at using RegEx and I just wanted to know if there was an easy way to check for a group of floats separated by a comma. Here are some things that I want to check for (basically looking for Vector3 positioning):

0.10, .10, -2.4 return true

0.10, +.10,-2.4 return true

1.0,-2.1 1.900 return false, no comma

Basically a set of (3) floats with no preceding comma or trailing comma and no definite length of the fraction values and the whole number can be either 0, blank, negative, or whole and it can accept positive or negative signs.

Would something like this work?

 

([-+.]*[0-9]+)+([,]*(, )*[-+.]*[0-9]+)+

 

(used RegExr to go through test cases appropriately)

Close but it must fail if number of sets !=3

Ahh, i thought it looked funny

This is basically what I did. I was just curious if there was an easier way:

^([-+\d]?([.\d]+)?([,* ]))([-+\d]+([.\d]+)?([,* ]))([-+\d]+([.\d]+)){1}?
