Hi evryone!

I have a problem 1 week now and I don't know what I am doing wrong. I'm making a small pixel game with some help. I was making a health-system, but I made the code and it just didnt worked. You can see why on the picture:



QWE has 15 HP and the healthbar is empty,
ZA has 16 HP and the healthbar is full.

the code I used:

if (HUDSHOWN >= 2){
         for(int i = 0; i <= modifier*2; i++){
            int manaColour = -1;
            int healthColour = -1;
            int mMax = 0;
            int hMax = 0;
           
            if(mana != 0 && maxMana != 0) mMax = mana/maxMana*16;
            if(health != 0 && maxHealth != 0) hMax = health/maxHealth*16;
           
            if(i > 0 && i < modifier*2){
               if(i - 1 < hMax){
                  healthColour = 500;
               }
               if(i - 1 < mMax){
                  manaColour = 115;
               }
            } else if(i == 0 || i == modifier*2){
               healthColour = 0;
               manaColour = 0;
            }
           
            int healthBarColour= Colours.get(-1, healthColour, manaColour, 000);
            screen.render(xOffset-2 + i, yOffset - 6, 1 + 27 * 32, healthBarColour, 0x00, scale);
         }
      }


Explain of the code:
The images are on a spritesheet and I can change the colours of the images. So I made a single healthbar piece that looks like 4 pixels above each other:

Pixel 1: [Always black (000)]
Pixel 2: [manaColour]
Pixel 3: [healthColour]
Pixel 4: [Always black (000)]

So at the borders I set mana and healthColour to 000. But in the middle I set the to how much health there is. Only hMax and mMax aren't working. It's probably because I made a little mistake or something. But I hope someone can explain it without saiying the code (Because I need to learn Java, not copying it).

[EDIT]:
Sorry placed the wrong code, it's this one:

if (HUDSHOWN >= 2){
         for(int i = 0; i <= modifier*2; i++){
            int manaColour = -1;
            int healthColour = -1;
            int mMax = 0;
            int hMax = 0;
           
            if(mana != 0 && maxMana != 0) mMax = mana/maxMana*16;
            if(health != 0 && maxHealth != 0) hMax = health/maxHealth*16;
           
            if(i > 0 && i < modifier*2){
               for(int ih = i - 1; ih < hMax; ih++){
                  healthColour = 500;
               }
               for(int im = i - 1; im < mMax; im++){
                  manaColour = 115;
               }
            } else if(i == 0 || i == modifier*2){
               healthColour = 0;
               manaColour = 0;
            }
           
            int healthBarColour= Colours.get(-1, healthColour, manaColour, 000);
            screen.render(xOffset-2 + i, yOffset - 6, 1 + 27 * 32, healthBarColour, 0x00, scale);
         }
      }

Thanks!

Probably some int casting problem:

hMax = (float)health/(float)maxHealth*16;

or

hMax = (health*16)/maxHealth;

Thx it worked!
