How to make a GUI or HUD

Archived Forums Questions & Answers

I know there are tons of threads on here about making a gui but none of them seem to be working for me. I am trying to use a GUI.Label and make a "PlayerHealth" variable visible to the player as a number, not a healthbar. i.e. it shows 100 when at max and you get hit it falls down to 94. Is there any way to link a interger variable into a GUI.Label script?

thanks in advance

ok so, this is my new code 

var PlayerHealthDisplay : int;

FPSWalker.PlayerHealth = PlayerHealthDisplay;

guiText.text = PlayerHealthDisplay;

but the console says "Cannot convert integer into String".

Now what?

Yeah sorry about that, I guess you do need to do to convert PlayerHealthDisplay into a string. Just try: guiText.text = PlayerHealthDisplay.ToString();

I think what you are looking for is not GUI.Label, but a GUIText

http://unity3d.com/support/documentation/ScriptReference/GUIText.html

When you have the Text in place, you can simply create a reference to it in your script, and change it's value by changing .text with your script.

So in C# just:

GUIText myText;
int myHeath = 100;
myText.text = myHealth.ToString();

:( im not too good at c#, if my variable is PlayerHealth, would i just replace myHealth in your sample script?

I think in JS, you don't need the .ToString()... Just: myText.text = myHealth;

Actually... Can't you just do a OnGUI script?

Like...

function OnGUI(){
    GUI.Label(0,0,200,200,PlayerHealth);
}

On the object that contains PlayerHealth? http://unity3d.com/support/documentation/ScriptReference/GUI.Label.html

If you're talking about using a GUIText though, like Smorpheus said above... It would be kinda like

theGuiText.text = PlayerHealth.ToString();

As he has done so above, with theGUiText referring to the GUIText you created, and PlayerHealth being the float/int variable you created.

If you want it Updated you should keep it inside of a function Update(){}
