Hello everyone,

I need help with my code. I want to make drills that consume fuel. At first I wanted to use the damage bar, but then I decided to use tooltips to show the amount of fuel. And here is my problem: I created a variable that is the amount of fuel. But when I use a drill, ALL the drills consume fuel instead of just the one. I know that this happens because I reduce the fuel for all drills with "fuel--;"(static context). How could I relate the consumption to the one that actually uses the fuel?

The DrillsClass:

Thanks in advance

ohhh, thanks, thats exacly what i needed

Hello,

Sorry for writing back again but despite several attempts I did not manage to change/create the tags. They always have the value 0.0

            pTooltipComponents.add(new TextComponent(val.toString()));


    }
}

 

Thanks

okay, but how can I then set default values and why and why is the value still 0 despite right-click(onUse)?
