Canvas drawing

[axelzellalex]

Canvas.DrawText(UTWeapon(PawnOwner.Weapon).MaxAmmoCount);

For some reason this is only out putting the current AmmoCount.
Even though I use the same call a couple of lines after:

DrawAmmoBar("",UTWeapon(PawnOwner.Weapon).AmmoCount, UTWeapon(PawnOwner.Weapon).MaxAmmoCount ,10,34,80,80,200);

I was also wondering how can i print out two text pieces but on the same line?
I am looking to have a standard "currentAmmo/MaxAmmo" (ie 4/20).

If I right understand you looking for this:

Canvas.DrawText("Ammo: "@CurrentAmmoCountVariable@" / "@MaxAmmoCountVariable);

[axelzellalex]

where '@curreammocountvariable@' is the name of my variable yes?

[Kuroi]

curreammocountvariable - name of your variable
@ - is string continuation symbol

[Kuroi]

"Ammo: "@CurrentAmmoCountVariable@" / "@MaxAmmoCountVariable - this means:
"Ammo: "+CurrentAmmoCountVariable+" / "+MaxAmmoCountVariable

and this print to screen:

Ammo: 32 / 50

[axelzellalex]

   {
		MaxAmmoCount = MaxAmmoCount;
		MaxAmount = ""$MaxAmmoCount;
    AmmoCount = Weapon.GetAmmoCount();
    lastweapon = weapon;
    lastammocount = ammocount;
    Amount = ""$AmmoCount;
    
    Canvas.DrawColor = WhiteColor;
    Canvas.DrawText(Amount);
    Canvas.DrawText(MaxAmount);
		}

thats my inital Ammo stuff, so i use the drawtext func:

Canvas.DrawText("Ammo: "@Amount " / " @MaxAmount);

[Kuroi]

Change to this:

Canvas.DrawText("Ammo: "@Amount@" / "@MaxAmount);

[axelzellalex]

bad or missing expression after "@" : "Amount"

[Kuroi]

what type Amount is?

}

thats my whole HUD.
at line 118, DisplayAmmo is where i set Amount and MaxAmount
then call at line 176.

[axelzellalex]

sorry i had it in the wrong place !!
thank you very much

[axelzellalex]

Oh wait, it displays as " 0 / 0 "
all the time...

[Kuroi]

Try change this:

   if (weapon.AmmoDisplayType != EAWDS_BarGraph)
   {
		MaxAmmoCount = MaxAmmoCount;
		MaxAmount = ""$MaxAmmoCount;
    AmmoCount = Weapon.GetAmmoCount();
    lastweapon = weapon;
    lastammocount = ammocount;
    Amount = ""$AmmoCount;
    
    Canvas.DrawColor = WhiteColor;
    Canvas.DrawText(Amount);
    Canvas.DrawText(MaxAmount);
		}

to this:

   if (weapon.AmmoDisplayType != EAWDS_BarGraph)
   {
       Canvas.DrawColor = WhiteColor;
       Canvas.DrawText("Ammo: "@Weapon.GetAmmoCount()@" / "@Weapon.MaxAmmoCount);
   }

i think i late with reply

[axelzellalex]

It still displays it as " 0 / 0"

[Kuroi]

Show current code of DisplayAmmo function.

[axelzellalex]

i changed to this

 Canvas.DrawText(""@UTWeapon(PawnOwner.Weapon).AmmoCount@ "/"@UTWeapon(PawnOwner.Weapon).MaxAmmoCount);

and it works fine ! thanks
how do i know when to use @ ?

[Kuroi]

how do i know when to use @ ?

use this when you need to add variables to string variable.

[axelzellalex]

cool, i think thats the same in php

[musilowski]

You can use the dollar sign ($) if you don't want a space between the strings.

[axelzellalex]

You can use the dollar sign ($) if you don't want a space between the strings.

Could you show me an example?
does $ not also mean Variable ?
