Percentage Explanation, please?

[Hblade]

I've asked this before, but now I'm actually ready to "Pay Attention". How would one go about making an HP bar but keep it's width solid and yet still be able to gain HP? Example, the start off HP is 100, but the HP Bar is 200Pixels. And never changes. How would I keep the HP bar 200 pixels even if the HP is 9999? and still go down slowly until it reaches 0?

If you have a fixed width, so a canvas's width, then the full width is 100% hp. Completely empty is 0%. Half of it, 50%. That's pretty straightforward, so, all you need is to multiply the width by the percent of hp, which can be obtained by hp/maxhp. If you make maxhp a variable, you can increase the player's maxhp at any time.

Thank you very very much!

Actually I'm still confused. What I currently have is:

Code: Select all

void Draw(int R, int G, int B, double TRANS, double VAR) {
    int i, i2;
    erase(0, 0, 0, 1); //Empty the canvas
    setpen(R,G,B,TRANS,1);
    for(i2=0;i2<250;i2++){
        setpen(0, 0, 0, 0, 1);
        moveto(i2, 0);
        lineto(i2, 12);
                         }
    for(i=0;i<VAR;i++) {
        moveto(i, 0);
        setpen(R+(255/250), G+(255/250), B+(255/250), TRANS, 1);
        lineto(i, 12);
                       }
                                                         }


And 3 variables
HPX
MAXHP
LENGTH

I tried:

Code: Select all

LENGTH=(HPX/MAXHP);


but that bugged out and only made 1 pixel line. I have:

Code: Select all

Draw(150, 0, 0, 0, LENGTH);


EDIT:
I tried

Code: Select all

LENGTH=(HPX/MAXHP)*250;


Which 250 is the width. now it just teleports to 0 o-o

Made a few optimizations, and since I honestly can't stand your bracket placement I changed that as well.

Code: Select all

void
draw (int R, int G, int B, double TRANS, double VAR)
{
    int i;
    erase(0, 0, 0, 1); //Empty the canvas
    setpen(R,G,B,TRANS,1);
 
    setpen(0, 0, 0, 0, 1);
    for(i=0;i<12;i++)
    {
        moveto(0, i);
        lineto(250, i);
    }
    setpen(R+(255/250), G+(255/250), B+(255/250), TRANS, 1); // what?
 
    for(i=0;i<12;i++)
    {
        moveto(0, i);
        lineto(VAR, i);
     }
}

Using, width*HPX/MAXHP should work.

Hahaha, sorry about that. I always seem to make messy code.

Thanks again, and "what?" I was trying to make it get lighter color for a gradiented look. >.> Again, a fail on my part.

Edit:
Oh god yes! It works! Thanks a billion. now only to find out the color gradient

Haha yes. I get really annoyed when I see people online put there brackets like that
No offense to you Hblade of course =D

[Hblade]

lol sorry guys xD

Same. For example, DST has done many great things but I can't understand the code because of how he places the brackets. It makes it very hard to understand where the brackets start and end.

[Hblade]

Where should I place the brackets? Oh and None taken LCL XD

[foleyjo]

I use this method

Code: Select all

statement  //The bit of code above the bracket
{
  code  //indented to make it easier to keep track of 
}


[SuperSonic]

Yeah, me too

[Hblade]

xD Alrighty, traditional it is :3
