Limited Size HP bar help [solved]

[Hblade]

Yes. AGAIN lol, I'm asking this same question for probably the third time. (This is what I get for not using GE in a while hehe). Basically I have a fixed-width canvas, I don't want it to get any bigger or smaller but I want it to be able to "draw" an HP bar. I got the bar drawing but how can I make it equal to the players HP again?

Code: Select all

int i;
erase(0, 0, 0, .5);
for(i=0;i<width;i++){
    setpen(255, i, 0, 0, 1);
    moveto(i, 0);
    lineto(i, height);
                    }


This is a small peice of code for an example, this draws an HP bar but when the HP is full, no matter how large or small I want it to stretch to the size of the canvas instead of increasing in size.

I wont forget again I PROMISE LOL

This has to do with percents. You know the max width of the bar, so you just multiply it by the percent of hp (remember, max health is 100% hp, and lowest health is 0%). width*1.0 will represent the full width, while width*0.0 will still equal 0.

Code: Select all

int hp_dist = ((float)hp/max_hp)*width;

Thanks again sky! Sorry for any inconvenience hehe

Edit:

Code: Select all

int i;
int hp_dist = (float)(hp/maxhp)*width;
erase(0, 0, 0, .5);
for(i=0;i<hp_dist;i++){
    setpen(255, i, 0, 0, 1);
    moveto(i, 0);
    lineto(i, height);
                    }


This for some reason isn't working, yet the text over the hp bar says "50/100"


Edit:
I also fail to see how hp/maxhp could result in anything -BUT- 0. Even as a float, it still returns a value of 0 when I debug using

Code: Select all

sprintf(text, "%f", (hp/maxhp)*HP_BAR.width);

Edit: fixed. thanks sky
