Hello everyone.

I have trouble with creating creating a hud. I'm trying to make a hud to show if the player is ads and have a specific weapon. And if the player doesn't do that, the hud will be removed from the screen. However, no hud creates at all.
And "self" is the player.

Why not?

create_ads_hud()
{
        text = undefined;
	while(1)
	{
		WeapName = self getcurrentweapon();
		if( self AdsButtonPressed() && WeapName == "zombie_colt" && !isdefined(text))
		{
		self AllowMelee(false);
		wait .4;
		text = create_simple_hud( self );
		text.alignX = "center";
		text.alignY = "middle";
		text.horzAlign = "center";
		text.vertAlign = "top";
		text.fontscale = 14;
		text.x = 0;
		text.y = -4; // -265;
		text.alpha = 0;
		text SetText( "Do something random, I don't know" );
		text.alpha = 1;
		}
		else
		{
		if(isdefined(text))
		{
		text destroy();
		text = undefined;
		}
		self AllowMelee(true);
		self SetClientDvar("cg_fovMin","60");
		}
	wait .01;
	}
}

Thanks in advance.

    !isdefined(text)

                if(isdefined(text))
		{
		text destroy();
		text = undefined;
		}

                if(isdefined(text) && !(self AdsButtonPressed()))
		{
		text destroy();
		text = undefined;
		}

Hmm. It is still not working, it is so wierd imo. "else" is for if the others statements are false right? Well I tried to print and see what happens if I print in the else statement, and it printed even if the statements were true. Why is that happening even if the statement is true?

Here is how my code looks now.

create_ads_hud()
{
        text = undefined;
	while(1)
	{
		WeapName = self getcurrentweapon();
		if( self AdsButtonPressed() && WeapName == "zombie_colt" && !isdefined(text))
		{
		self AllowMelee(false);
		wait .4;
		text = create_simple_hud( self );
		text.alignX = "center";
		text.alignY = "middle";
		text.horzAlign = "center";
		text.vertAlign = "top";
		text.fontscale = 14;
		text.x = 0;
		text.y = -4; // -265;
		text.alpha = 0;
		text SetText( "Do something random, I don't know" );
                wait 1;
		text.alpha = 1;
		}
		else
		{
		if(isdefined(text) && !(self AdsButtonPressed()))
		{
		text destroy();
		text = undefined;
		}
		self AllowMelee(true);
		self SetClientDvar("cg_fovMin","60");
                iprintln("none of the checks shouldn't be true");
		}
	wait .01;
	}
}

create_ads_hud()
{
    text = undefined;
	while(1)
	{
		WeapName = self getcurrentweapon();
 
		if( self AdsButtonPressed() && WeapName == "zombie_colt" && !isdefined(text))
		{
		self AllowMelee(false);
		wait .4;
		text = create_simple_hud( self );
		text.alignX = "center";
		text.alignY = "middle";
		text.horzAlign = "center";
		text.vertAlign = "middle";
		text.fontscale = 14;
		text.x = 0;
		text.y = -4; // -265;
		text.alpha = 0;
		text SetText( "Do something random, I don't know" );
		text.alpha = 1;
		}
		else
		{
		if(isdefined(text) && !(self AdsButtonPressed()))
		{
		text destroy();
		text = undefined;
		}
		self AllowMelee(true);
		self SetClientDvar("cg_fovMin","60");
		}
	wait .01;
	}
}

text.vertAlign = "top";

text.y = -4;

text.vertAlign = "middle";

text.y = 40;

This is the code that I used and tested:

create_ads_hud()
{
    text = undefined;
	while(1)
	{
		WeapName = self getcurrentweapon();
 
		if( self AdsButtonPressed() && WeapName == "zombie_colt" && !isdefined(text))
		{
		self AllowMelee(false);
		wait .4;
		text = create_simple_hud( self );
		text.alignX = "center";
		text.alignY = "middle";
		text.horzAlign = "center";
		text.vertAlign = "middle";
		text.fontscale = 14;
		text.x = 0;
		text.y = -4; // -265;
		text.alpha = 0;
		text SetText( "Do something random, I don't know" );
		text.alpha = 1;
		}
		else
		{
		if(isdefined(text) && !(self AdsButtonPressed()))
		{
		text destroy();
		text = undefined;
		}
		self AllowMelee(true);
		self SetClientDvar("cg_fovMin","60");
		}
	wait .01;
	}
}

You have:

text.vertAlign = "top";

and

text.y = -4;

If you change this to :

text.vertAlign = "middle";

or change this to

text.y = 40;

You will see your hud.

The reason it prints is because you put the print in the else statement. The first statement is only true when you ads. As soon as you do, it waits the total of the waits you have in and then continues to print, and neither statement is true until you release ads. Then again when you hit it again, and so on... If the print statement was in either if statement it would have behaved differently.

text.y = -4;

text.y = 40;
