[color=red]Hello! I'm red![/color]
[style=font-size: 12pt]i am smol[/style]

This is how many gems you've found: [icon=bloodDiamond][var=bloodDiamondMined] [icon=diamond][var=diamondMined] [icon=ruby][var=rubyMined] [icon=emerald][var=emeraldMined] [icon=sapphire][var=sapphireMined]

Here's your combat cooldown: [icon=combatSkill][time=heroCooldown]

Oh boy, this one is complex. Let's take a look at your rocket status:
[if=return var_rocketStatus=="1"][gif=rocket][/if][if=return var_rocketStatus=="3"][gif=rocketBack][/if] [eval=if(var_rocketStatus==1) return formatTime((384000-var_rocketKm)/2); else if(var_rocketStatus==3) return formatTime(var_rocketKm/2); else return "--:--:--"; ]

You can also use some of lassebrus's functions, which are included with this script:

        hudParsed = parseHud(hud);
    }

    function save() {
        localStorage.setItem(KEY_CONTENT, hud);
        hudParsed = parseHud(hud);
    }
