Hi Guys, how i put a IF in a text field for example:

		GUI.Box (Rect(Screen.width * (guix),Screen.height * (guiy),Screen.width * (guiw), Screen.height * (guih)),
	
	if(RifleShort > 0){ "Content" }
	
	);

But, not work :confused: Have other Way? I tryng to make for example,

if(RifleAmmo > 0){ "
RifleAmmo : More thanā€¦" }
if(PistolAmmo > 0){ "
Pistol Ammo : More thanā€¦" }
if(SubMachineGunAmmo > 0){ "
Subā€¦ Ammo : More thanā€¦" }

An if statement influence the control flow and represent a conditional branch in the execution order. It can't be used inside an atomic instruction as parameter.

If you want to pass a different string as parameter depending on a condition you have several possibilities:

  • Use a variable as parameter which get set to the desired value before you call your GUI.Box:
var text = "";
if(RifleShort > 0)
{
    text = "Content";
}
GUI.Box (Rect(Screen.width * (guix),Screen.height * (guiy),Screen.width * (guiw), Screen.height * (guih)), text);
  • direct call different versions:
if(RifleShort > 0)
{
    GUI.Box (Rect(Screen.width * (guix),Screen.height * (guiy),Screen.width * (guiw), Screen.height * (guih)), "Content");
}
else
{
    GUI.Box (Rect(Screen.width * (guix),Screen.height * (guiy),Screen.width * (guiw), Screen.height * (guih)), "");
}


GUI.Box (Rect(Screen.width * (guix),Screen.height * (guiy),Screen.width * (guiw), Screen.height * (guih)), ((RifleShort > 0)?"Content":""));

The ternary operator should be avoided since it results in very long lines and it's difficult to read.

Wellā€¦ the simple answer is to just assign it to a string and apply the assigned stringā€¦

var theString : string = "DEFAULT";

if(RifleShort > 0)
    theString += "Conent";

Debug.Log(theString);

Then you can use that string however you wantā€¦ soā€¦

var theRifleString : string = "";

if(RifleAmmo > 0)
{
    theRifleString = " n RifleAmmo : More than...";
}

var thePistolString : string = "";

if(PistolAmmo > 0)
{
    thePistolString = "n Pistol Ammo : More than...";
}

var theMachineGunString : string = "";

if(SubMachineGunAmmo > 0)
{
    theMachineGunString = "n Sub... Ammo : More than...";
}
