unity float from another gameobject
// If your script is monobehaviour:
// You can use
GetComponent<ScriptName>().yourfloat
// if the script is on the same object as your other script.
// Or find the object first with a tag using
GameObject.FindWithTag("yourobject")
// and then do
.GetComponent<ScriptName>().yourfloat
// if your script is not monobehaviour you will have to make a new instance like
yourscript script = new yourscript();
script.yourfloat
// or make your float value static and you can do yourscript.yourfloat without making a new instance.
