Tag comparision with a string as variable doesnt work

Questions & Answers

very simple: I get the other as a string and if that string is equal to the tag of the player it should do smoething

    private void TakeDamage(string other){

    Debug.Log(Player.tag + " " +other);

    if(Player.tag == other){

        Debug.Log("attack player");
    }

}

The Debug.Log shows that both strings (tag and other) er exactly the same. But it just doesnt work. I tried it with Player.CompareTag and got the same result.

this is the Debug.Log:

tps_player tps_player (UnityEngine.GameObject) UnityEngine.Debug:Log(Object)

The tag of a GameObject is just a string, so that comparison will work if they are equal. since it doesn't work they are not equal. Maybe a space at the end?

ps. what does `tps` stand for? you don't wan't to write `fps`?

The existence of the CompareTag method suggests that tag strings may be stored in a way that doesn't work properly for normal string comparison.

Try this:

if(Player.CompareTag(other))
...

If that doesn't work, you could inspect the bytes of each string with a method like this:

void LogStringChars(string s)
{
    string msg = s + "=(";
    foreach (char c in s)
    {
        msg += (int)c + ",";
    }
    msg += ")";
    Debug.Log(msg);
}

Just add the following to your method ...

LogStringChars(Player.tag); 
LogStringChars(other);

Ok I found another way... or... I probably found the main problem.

the "other" string I sent was actually the name of a gameobject (I used gameObject.ToString(); to convert)that had the same name as the tag! Somehow unity makes a difference between strings and their origin.

So what I did now was to send the gameobject.tag instead of the gameobject.ToString(); which would have been the most logical in the first place... dont know what I was thinking there -.-

If you want to know if something is a specific game object, you can test if the gameObject is equal to the other gameObject.

Tags are good for testing if the hit item is part of a group of things.
